my htc hd7 driving me crazy and i tried many roms but still the same problem after 5 or 7 days of flashing the new rom my phone suddenly do a hard reset i lost many pictures and many other because of this can any one help me plz
Sounds very much like a hardware bug. I'd get the phone replaced under warranty if I were you.
Are you flashing stock ROMs or custom ones? The custom ones may be less stable than the stock, but you shouldn't be having the problem you describe anyhow. Does anybody else have access to the phone? It's entirely possible for kids to accidentlaly hard-reset the phone; it takes a little effort but less than you might think.
i flash custom roms and no one touch the except me and my phone warranty expired
It's entirely possible that the custom ROMs are buggy, and even slightly possible that they damaged the phone somehow (not likely, but possible). Have you tried flashing a stock ROM and seeing if the problem continues? Be aware that it will overwrite HSPL if you do so, but it's easier to re-unlock the bootloader than handle constant hard resets.
If that doesn't fix the problem, you're probably SOL. I've not heard of anybody else experiencing what you describe unless it was a hardware problem. I guess you could try opening up the phone (it's tricky but totally possible, especially if you don't mind voiding your already-expired warranty) and re-seating the internal microSD card.
i opened the phone and re-seated the sd card now i must wait 5 days
if it reset again i will try to flash it with the stock rom
I hope that helps! Sorry I can't offer more advice (except to search for anybody else who has had this problem). My HD7 has stayed perfectly stable without a single unexpected hard-reset, so I can't help you from experience.
Have you changed the stock sd card to a higher capacity/different sd card at some point?
This could be the cause, if the card is not 100% compatible/fast enough etc. After 5-7 days of use the memory card could reach a point where it has certaint level of data and the problems start.
EDIT: Asking because you so nonchalantly told you opened the phone and re-seated the sd card, kind of gave me the impression you did it before?

hhh yes i did it before to change the sd card from 16gb to 8gb class 2
i noticed that if i put the phone in my pocket it became too warm from the down back side maybe this is the cause of the problem
and it get very hot if i put it in charge too
The class 2 card is too slow, stock is class 4. Putting too slow card in the phone can cause all sorts of problems.
I changed on my HTC 7 Pro from SanDisk 8gb class 4 card to SanDisk16 class 2. After 4 days or so it started to cause resets and after little more time programs wouldnt run anymore etc.
Now I ordered a Samsung 32gb class 10 that people all seem to have good results. It was 32eur delivered. The phone is wayyyyyyyyyyyyyy faster and no more problems at all. I installed it a week ago.
What I read its not only the class either, some cards seem to have compatibility issues also. This Samsung card seems to be working for everyone, but there are more choises.
The "class" rating on SD cards is a rough measure of their sequential read and write speeds. This is important for things like cameras, which need to rapidly write a lot of data in a smooth sequence. The phone needs a certain amount of this, but not much - Class 4 cards are about as slow as you can buy today, and will do just fine. What the phone does need is extremely fast random access. Many SD cards, especially "high-speed" ones, actually perform relatively poorly in this regard. It's generally not tested for, either, so even within the same brand of card individual chips may vary.
Im sure whats above is correct, I dont know much about the tech side of this.
However Im pretty sure the OP's problems are due to the sd change.
The thing for me and what Ive read for others too, is that the problems do not start right after change of the card, everything looks normal for a while.
yes every looked normal in the first week but before this class 2 8gb sandisk card i tried a normal card calss 4 16gb and it didn't work
Reliable 32gb Samsung SD card ?

I don't suppose you have a link for this Samsung card do you ? I'm a bit wary of buying SD cards due to all the problems with compatibility and fakes.

Well I know about the fake cards, specially on eBay. I bought from eBay , German seller, member since 99 and sells a lot of memory.
The seller seems to have raised the price for the card little since I purchased, I paid 27,90+shipping. (he had +10 sold at that point, now 40)
Here is the link for that :http://www.ebay.de/itm/180835219519.
EDIT: The price seems to be at the right ballpark for this card. I saw similar price (discounted) for the same card on some store link posted here at XDA. It was some of the topics regarding memory upgrade on WP7 device (most likely at HD7 or HTC 7 Pro section).

I have to hard reset my phone this weekend due to a bizarre problem with Internet Explorer on my phone, if that doesn't fix it, I may swop out the sd card and flash my first Rom
Do keep us posted on your new card.

Im using Ansar's lates rom btw. When I started to have problems with the old card I didnt flash a new rom, just changed the card and did a hard reset... Tomorrow I think it will be 2 weeks with this new card, no weird behaviour at all.
i changed my memory to sandisk 16 gb calss 4 and now my phone reset and restart many times a day omg i can't find the samsung calss 10 in my town and i can't buy from ebay
There are other cards that work too. You can find more info about cards here: http://forum.xda-developers.com/showthread.php?t=883582
Read and surely you can find a card you can buy from your city.
where i can find the memory card references?

Hi, I recently bought a 2GB MiniSD card for my Treo750v. When I put it into the system it worked fine, I installed some programs and put some music on. Then I left the phone alone for a while and the automatic keylock came on. When I returned to the phone and activated it from keylock the sound that is played when removing the card was heard and it reported that there was no card installed when there clearly was. To return the card to working order i had to remove and re-insert it. After that it was fine until keylock came back on and the same thing happened again!
Anyone got any ideas on why this is doing what it is doing!
Point to note, the card works perfectly in an HP device running WM5 and my Digital Camera!
I am starting to think this is a "problem" with the Treo because mine does the same with a 512mb card. Sometimes it wont be "seen" by the PDA but not a problem when put in my other pda.......
Jim
I get the same thing, also with a 2 gig card. But it happens only every other day or so. Still very annoying. Have no clue why this is happening.
I had the same trouble, too. But the trouble has already disappeared by replacement of 2GB mini SD to 1GB mini SD.
Remainning problem is that Spb pocket plus still cannot get application icons on storage card.
Went to a Vodafone store today and told them about the issue. They said it is a known issue and was a problem on a couple devices. They said if I would bring the box and invoice, they would exchange the device. Will do that in the next few days. Hope that solves it.
I have the same problem with my 512mb card and my 2Gig card. But I am in the U.S. and cant bring it in to Vodafone. Does anyone know what else can be done?
I should've did some homework and checked this forum before jumping on my 2GB which I bought 3 days ago. 'doh... I have the same issue here... except in the midst of playing with it, inserting and removing etc... all the data got corrupted. I have to figure out how to reformat the whole card.
Hopefully, there's a software fix later.
Hey
Thanks guys n gals for ur help!
magxs I might have to do the same!!!
Oh bum, silly silly smartphones! I just want something that works!
I've also been having problems with my Treo 750v and the miniSD card (2GB SanDisk Ultra II).
When I insert the card, the Treo sees it and can run programs that are installed on it. When I return the Treo after it has been off for a while the card is no longer recognised and the memory manager claims that no storage card is installed. At this point all I can do is either take the card out and reinsert it, or otherwise to a soft reset. The time it takes for the Treo to loose its connection to the card varies; sometimes I can turn it on after a few minutes and the card is gone, sometimes it still works after a couple of hours.
When I came across this discussion yesterday, I phoned up Vodafone and reported my issue. According to the customer service rep, this is not on their list of known issues but he agreed to an exchange anyway. I'll get the new device today. I hope that'll fix it, but by now have my doubts.
Someone else suggested formatting the SD card, citing issues with FAT16 vs FAT32. I might try that if the new Treo still suffers the same issue.
In another thread on this topic, someone reported that such an issue was observed on some other PPC device and was fixed by a ROM upgrade. I emailed Palm about it. Palm eventually got back to me today saying:
This may occur only with cards that are not Palm branded. If possible please try to use a Palm card to test it.

Either that's a lame excuse, or they're trying to force people into buying their overpriced own branded accessories by making their hardware incompatible with the industry standard. Unless SanDisk don't know how to make miniSD cards...
I guess my next step - after the reformatting - will be to throw £60 at a Palm branded storage card; I don't expect that would work any better than my current card, but at least then Palm can't argue that I'm using "unsupported hardware".
I exchanged my Treo yesterday at a different Vodafone store. The people there didn't know anything about SD card issues either, but they exchanged it anyway. Have been running the new device for about 24 hrs now and no issues, yet. But even on the first device, the problems only started later and even then it wasn't an everyday occurrence. So, I will need to watch it a bit longer.
new rom
Have you tried loading the Cingular ROM and see if it fixes this problem?
After two full days with my new Treo, the SD card was lost again over night. So, it doesn't seem to be an issue that just a few devices were affected by. Too bad....
I didn't try any other ROMs yet.
I have the Cingular ROM, and have the same exact problem.
hi,
i am new to this board and hope you dont mind my bad english. i am from germany and proud owner of a treo 750v
and i tell you what: i am so glad i am not alone with the storage card problem.
it was nearly making me mad.
now i know that there are a lot of other people with the same problem. that may not solve it but gives me a better feeling an hope for an update which solves that.
PS: i use a 1gb sandisk
Well It's working
I bought another MiniSD card the other day, a 512Mb Kingston one, and so far so good, it works well (about 5 days now) and has not been "lost" so far! Not sure if it's the size of card or the make or what but I will keep investigating this!
Hope you resolve your issues!!

What kind of card did you have issues with?
I get the feeling the this might be related to specific cards. To find out: please everybody state which card you are using and if you have problems.
I'm using Sandisk Ultra II 2GB and it's dropping out.
Thanks

Card Type
Mine was a generic 2GB card bought on EBAY but the one that is working now is a Kingston 512MB card. The Generic 2GB works perfectly in my Digital camera. There are no Identifying marks on the 2GB card sadly so Cannot say for sure who makes it!
I'm also using a SanDisk Ultra II 2GB, and it's getting dropped regularly.
Sounds like SanDisk is the one to blame.
But would be good to have more reports before we all go out buying new cards. Keep em coming...
My shiny new Galaxy S III has now destroyed two 32gig micro SD cards on me. About two weeks after I installed the first card, my phone started giving messages about the SD card being improperly removed, then it would immediately try to re-mount it, then would say it was removed again, then finally started just repeating the "unable to mount SD card" error until I physically removed the card. I argued with best buy to give me another one, and now today (about two weeks after installing the new one), the same thing happened. I put the card into a USB reader to try it on my computer, and now even my PC does not recognize the card.
Has this happened to anyone else? What can I do to fix this?! I pre-ordered the phone from verizon, so I'm now well out of warranty replacement time.

I have a 32gb MicroSD card and haven't had a problem. I do wish I could use it more as internal memory rather than hardly usable external storage...but that's a different issue.
Sorry I couldn't help, but just wanted to say that Galaxy S III does support that much external storage. Maybe a hardware issue? Try troubleshooting it with another MicroSD card.

Gotta be the cards you're getting I would think. I had a 16gb card that came with my Droid x almost 3 years ago in it for almost 2 months before the card finally crashed.(I'd abused that card tho, carried it in my jeans pocket, left it sitting on my table etc) Then I put my 64gb in it. It's been a little over two weeks now and no probs with it. I've written too it and erased and so on so I've actually used it. It's almost full now actually lol.
I have that same 16 GB from the droid x. Do I still need to format it if I flash a ROM? And how do I check what format its in

My 32gb card was doing that on stock until I finally installed a custom rom. No problem since.
Synergized GS3
SD card gs3 issue
I also had trouble with my external 16gb card after flashing 2 ROMs (synergy & beans v9). I was not even able to get a computer to recognize the sd card after the flashing.
I thought it had to do with using a stock, then rooted stock, then custom kernel. i thought the combination and repeated TBU access over a 4 day period just trashed it. maybe there is more to the story?
1) What is your ROM flashing history (what roms, how long were each installed)?
2) Which rom did you notice the problem on?
3) Were the original and replacement cards the same make/model?
4) What format were the cards in (FAT32, exFAT, or other)?
5) are/have you overclocked your cpu?

Thanks for the responses guys. I'm still fully stock, I haven't done anything to the phone (yet). I don't know what the format was, I just put them straight into my phone and let it do whatever it wanted to do. The original and replacement are the same make and model, from the same store. So before i panicked too much, I was considering buying a new/different card from amazon and seeing if it does the same thing still.
Just didn't know if anyone else was experiencing this, or had any thoughts on why that would randomly happen on a completely stock phone?

That sounds like your best bet. There are plenty of crappy cards out there. My ADATA 8GB class 10 has been great so far. I have noticed that the GS3 gets really hot right near the cards (micro sd and sim). Can't be great for the cards long term.
I've had my VZW GS3 since 7/5 and have been fine with my card. I've seen plenty of people who've had trouble with FAT32 vs exFAT, but none who have lost their card.
I have seen a ROM break cards before (an early AOSP gingerbread build for the Fascinate claimed one of mine), so I've actually been looking. This is the first thread I've seen.

I've also noticed it gets really hot toward the bottom of the phone. Now that I think of it, both times I noticed the SD card issue right after taking the phone out of my pocket. Maybe it's just getting too hot? I wonder if my case is also holding in a lot of the heat and making it worse? I wish there was a way I could test things without breaking an SD card every time!
My GS3 fried a new 32gb card that I put in it after about 3 weeks. Randomly got an "unreadable SD card error", can't correlate with any specific activity. I reformatted the SD card & it works again in the phone. I was rooted, running stock at the time. Maybe it's the heat, but I don't recall it being hot at the time (I also don't recall it not being hot...)
Try sandisk.I was having problems with lesser brand

I have been using the 32 GB San Disk brand card that came with my thunderbolt and it's been working great.
I really don't know what could cause that to happen to a card and I haven't noticed any other reports of it happening with this phone.
If it comes down to it VZW SHOULD give you a replacement because it could be something to do with the card slot in the phone. I would try talking to them if you can't get it worked out.
So going on the theory that maybe it's just getting too hot, I just ordered a 16gig sandisk ultra micro SD card. It claims to be "temperature proof", whatever that means. Hopefully that clears things up, otherwise I'll have to deal with Verizon, and I'll be super mad if they give me a refurbished phone when this issue actually started two weeks after I got the phone.
If I don't post back here then you can assume all has gone well!
16gb card from droid x
same as others, used the same 16gb card from my droid x, transferred to the bionic when it was released, and now have been using it in the GIII since release. no issues.
I don't believe the phones are getting too hot to do the damage. The hottest temp my battery has gotten had been 106 and they say that heat damage isn't even a concern until around 140 or so. I would think the cards could take the same if not more than the batteries.
I had a similar problem, my sd card wasn't destroyed, but it would randomly become unmounted. It started happening after I hooked my phone up to my corporate email and it forced me to encrypt my device. After I removed the corporate account it stopped happening. This was all on stock TouchWiz from the factory.

I have had my 64gb SD card for a month and so far nothing went wrong. did you buy your SD cards from a reputable source? I have always used sandisk SD cards try buying one from Sandisk or even Samsung. if you bought your card from ebay make sure the card works, I have heard that some times people sell damaged cards for very cheap. But other than that good luck.
16 GB class 10 sandisk 30 mb/s version died on me with this phone after 2 weeks, stock ROM, formatted with phone. It was brand new.
The error I had was it became read only. And no it was not fixable, I tried everything. Low level format, checking permissions, different OS's, putting it in SD adapter and messing with lock switch on there.
I read class 10s are more prone to die quicker and aren't necessarily better, but just different from a lower class. Ie a lower class will last longer because it read and writes differently and doesn't skip certain safeties like a class 10 does.
Running a class 4 16gb sandisk now and it is annoyingly slow.

I was going to post this in response to a couple of people in the development sections but my post count is too low so I'll post it here instead.
The SD slot in this phone seems to have an issue with corrupting SD cards, I've had to format both my old and new SD card multiple times with this phone as it becomes unusable every few days. I'm not versed enough in hardware to know if this is a bad connection between the SD slot and the "motherboard" of the phone. I've seen a number of people have their SD cards go bad with this phone and I assume that means we had a manufacturing issue. It would be really cool if a hardware hacker experiencing this issue could take a look inside and confirm whether or not the hardware is connected correctly.
Well, perhaps there's a high number of bad readers....
I've had the same card in my Q since the day I got it (mid-September), no issues.
Mine wouldn't read the day I swapped up from My Epic 4g Touch to This phone, So I popped in an sd reader backed up my data then let the Moto format it, no issues sence
Curious to know what class of card you guys are running. I've been running a Patriot class 10 but my previous was a class 4 without branding that came with my old Transform.
I'm really hoping that I just had my old SD card die at a bad time and that my newer SD card was just sent bad. Today I couldn't get the card to read from the SD slot in my computer, and it would not be cool if my phone caused it to become that way.

Class 10 Maxell

No issues here. I tossed the crappy class 2/4 that shipped with my Epic long ago.
Well I found an extra class 4, 2 GB SD card lying around the house when I was cleaning today. It may be that the local shipment of phones was bad, so if this SD card goes on me then I'll try exchanging the phone in another town just to be safe.
Just out of curiosity does anyone know whether Sprint orders enough phones for replacements with their original shipments? I'm not from a very large town so I'd imagine they would keep replacing with phones from the same batch.
I've got a Samsung 32GB class 10 mSD.
Nearly everytime I reboot my Photon Q it says "SD Card is damaged".
Go into settings, Mount SD Card once or twice and it works.
I've read, that other Android Devices have also problems with that size of SD Cards. (Google)
I had also problem in recovery restoring a backup, the restore process didn't went correctly
(said that everything was fine), had to use my 2GB mSD, which worked nicely and the backup also.
So I think it's an android/kernel issue than a hardware issue.
I have noticed that I get the corrupt sdcard error everytime I try to use the "mass storage" or "media device" setting with Windows.
I use Ubuntu 99% of the time and leave it connected in "camera" mode, have never had that pop up like that...
I usually just use ADB to copy everything anyway so I do not miss the "mass storage" mode at all.
Just had a 16gb class 10 microcenter branded card go belly up on me. Phone just all of a sudden said it was removed and now nothing seems to recognize the thing. The mount option is completely greyed out, and does the same on my note 10.1 if i pop it in there.
When your cards have gone did they completely disappear and refuse to read?

I wonder if it's the c10 cards...
You guys really shouldn't be using high class cards in a phone - there's really no benefit, as phones use SD card's very differently from camcorders or cameras...
On my ooooold phone, anything above Class6 was bad juju. I have always had class4 or lower cards, no fried cards (yet... lol)
kinda what I am feeling too. Not sure what class card I have but it was just a cheap 32gb from wallmart... Only had that error pop up once with this one though, and that was after trying to use usb storage.

Class 10 shouldn't make a difference to a device. The class/speed only comes in to play when transferring data from/to a computer, which will be faster on Class 10 vs Class 4 or 6.

As best as I can tell, thats a negative. Ive been running with a 32GB class 10 since around when the phone was released, and Ive had no issues. Quite surprising on its own, seeing as I abuse the poor thing. True that class 10 arnt useful for the phone specifically, but some shops only carry class 10 cards.
@hfase
I dont seem to have any issues with mass storage, with ~1GB written a day. Im quite curious as to why some people have this issue.

Quite surprising on its own, seeing as I abuse the poor thing. True that class 10 arnt useful for the phone specifically, but some shops only carry class 10 cards.
@hfase
I dont seem to have any issues with mass storage, with ~1GB written a day. Im quite curious as to why some people have this issue.

Maybe it's all down to the quality of the actual card itself?
Perhaps the cheaper no-name / off-name brands have a much higher failure rate....?
I'm not really sure, short of actual hardware issues on the device.
AW: Your SD card likely isn't the problem
Well here is my experience:
I am using a new san disk 32GB class10 micro sdcard. It was never format ed/ used before. The q itself formated the disk.
I have had no problems until using the twisted asanti prebuild
Version. Since then I only got problems with the qu saying the sdcard would be corrupt, after reboot. ( I expected some additional wired things, like the currents widget, which I deleted before reboot reappeared). So I would suggest it is an error in un mounting the sdcard before shutdown, which causes this failure.
Since I usually do not reboot the phone expect for flashing new roms, I had no trouble since then.
Hope this might help to further circle the problem, and maybe find a solution for this.

Since CM10 I haven't noticed any SD-Card issues, but I have the feeling, that there are some issues, which aren't detected.
In the last few days my CM10 was acting weird.
1. The gallery (together with the camera app, 2in1 app) disappeared in the App Drawer (was still in /system/app) and didn't appear again after overwriting gallery2.apk again.
2. The Google Weather App had a graphical issue, so I was sure, that there was a flash issue by restoring ASA14 and flashing CM10 (from SD-Card!).
I solved this issue in copying the nandroid backup and CM10 to the phone and flash it from there.
I have tested my SD-Card in my external cardreader, it had no issues in doing so.
My guess is, that the SD-Card needs more power than the Photon Q can give and is losing some read/write commands.

I think This may have hit the nail on the head. I have had a couple cheap discount cards die but they really died. Cant even read in the PC and one even got really hot when plugged in. Got a good branded card from amazon and havent had a problem since.

I've used better Samsung and Sandisk cards and have had this issue. It just randomly wipes all my data and creates the LOST.DIR with it all in there, but file names are all renamed and would takes years to sort through and try to figure out what is what. All my photos, music, etc.. were basically gone then. It didn't matter that the card was a name-brand or not. I've had the issue with several cards.
I constantly have this problem as well, and I've found that mounting the SD card with a reader or in another phone in a Linux environment fixes it for the most part. I think files still get lost, but you get most of what you had back.
I got a 32GB UHS1 card last week and it hasn't had a problem.
Hello guys, I have problem with my 16GB and 8GB MicroSD, it just standard class not class 10. I got weird behaviour, maybe many people facing the same issue with me. My sd card removed unexpectedly even my sensation was idle. There's no heat no heavy usage running. Tried reformating several times but again this problem still there. Tried changing rom from ViperS, CM10.2, CM11 no luck. Also I had already returned to the distributors with the new microsd but again, it happens to me. I don't why when I use 4GB my sensation running fine, no problem at all. This is the Sensation limitation? Maybe people have some advice how to solve this problem. Thank you
anyone?
Never heard of it, I've used 8gb, 16gb,32gb, and 64gb on multiple htc sensations, never had a that problem you describe.
But, it sounds like the pin might be lose?? does the card pull out easily when you pull it? i.e. you don't push it in first to get it out but even in this case, the card should be lodged safely inside the enclosure. Maybe it's bad design on the card? like too thin or something and so the electrical contact keeps shorting out
try googling
Sounds like a bad SD card to me. I'm using a 64GB Sandisk card without any problem.
I found this thread mentioning problems with S-ON might cause this.

I thought it was my bad sdcard too. Because now I've tested sandisk 4Gb class 4 running without any problem. Don't know why with Vgen Sdcard(local brand on my country) I keep facing this problem, both 8Gb and 16Gb. Maybe the vgen sdcard can't survive with high temperature on sensation, since sensation sometimes getting hot. Today I've ordered Sandisk ultra 8Gb class 10 and will check if the problem still exist.
I can get my phone to backup to the Samsung account and cloud but if my sdcard is In it takes an ungodly amount of time to calculate the amount of music I have on the sdcard so I give up.
I've switched it dso it doesn't backup my music (which is on the 128gb memory card) but it still wants to calculate it every time.
I want to be able to backup without having to take the memory card out
Any ideas?

Do you have wifi turned on?
yes
it works perfectly........... but only when the sd card is out of the phone. before backing up it seems to want to calculate how much music is on the sd card

I have a 200Gb card with loads of images and music and don't have any issues. Did you disable any services with Package Disabler pro? That might be an issue as when you restore a backup from the cloud you have to re-enable all services.
Could be a fake SD card. Did you buy it from a reputable seller? Fake cards can be incredibly slow or take ages to scan contents because they often use shady tactics to make the card appear to be 128Gb for example when accessed on a phone or PC while in reality being much smaller in capacity (2-16gb etc). These fake cards can look incredibly convincing too so dont be fooled by an elaborate copy.
Here's an app from the Play Store that can check if you have a counterfeit sdcard, SD Insight. The app isn't compatible with the S8 but if you have an older phone you can test your sdcard.

If its been with you for at least 3 phone cycles, was the speed ever really that good to begin with? It sounds like it may be an older card perhaps. Keep in mind, technology moves quick.
If you happen to be using a card that was cheap/midrange only a couple years ago, it would stand to reason that it may be underwhelming and feeling pretty slow by today's standards.
Download an app along the lines of "A1 SD Bench" and run a test for me. Post your Read/Write speed results in here for us when you're finished.
If the result of this test is poor you may want to look at the newer UHS-I supported cards if speed is becoming an issue.
I bought the card pretty much when 128gb micro SD cards were released and use it every day in the phone with no problems to play music and store pics
To be fair I presume that means it's old tech and I've been meaning to replace it. Just bought a brand new Samsung 256gb one.
Don't understand what any of the jargon means regarding sdcards and can't be bothered to test the issue.
To be fair it never occurred to me that the card is a bit long In the tooth as I've used it with the s7 edge with no probs. So just surprised the s8 struggles

Why even bother posting if you "you can't be bothered to test the issue?"
Because I decided I wanted to.
I tend to do what I want and considering the card is in 100% working order what's the point.
If times have changed and I've gotten to answer that it's old tech I can replace it with newer tech.
Thanks for your help but I can assure you I'll post what I want, when I want, how I want. I don't have to do anything I don't want to when I've already been told the card is old tech

Ah yes, I figured that was the case. It will be interesting to know if that new card solves your problem. If you still want to run a quick benchmark on your old card its not as involved as it sounds. If you use the app I recommended before you just choose your SD card in the UI and it should only take a few minutes to run a speed test.
Read speed: 33.97 mb/s

Presume this is rubbish. I bought the SanDisk card the week 128gb cards were released in the UK so it's quite old now but never had any problem with it.
All photos and all my music is on the card. Never had any issues with it. Have now purchased the following:
Samsung MB-MC256DAEU 256 GB EVO Plus MicroSDXC UHS-I Grade 3 Class 10
My 2 year old 200Gb card:

Oh wow, that write speed is pretty terrible. The read speed is "passable" I guess but still below average and well below the UHS-I cards.
I had one of the first 64GB Sandisk cards (around the time of the Galaxy S4 I'd like to say?) so I know what you mean but that thing was relegated to my drawer long ago after I realized just how agonizingly slooow it was.

it isn't slow
it's perfect for listening to music from and saving all pics to. perfect to the point of there would be no need to change the card. exceptional performance.
why the s8 has issues trying to calculate the amount of music on it to back-up even when i've toggled it NOT to backup music is a bit of a stupid upgrade on the s8 when the s7 was fine.
maybe samsung haven't figured out that most sd card users just throw pics, film and music on it so it doesn't need to be super fast as they've toggled off the backup option. seems to be a really strange software decision to try and calculated stuff to back up you don't want backing up lol
Objectively it is on the slow side but I understand what you mean. If all you plan on doing is copying a load of files to it once and only need it to access a few songs or pics here and there than you're right it should be fine. Let us know if you're able to solve your issue with a new card or whether the problem persists. :good:

I've used it all an excuse to buy the 256gb card though.
Is the one I've bought any good?
Samsung MB-MC256DAEU 256 GB EVO Plus MicroSDXC UHS-I Grade 3 Class 10
Its quick as hell. "Up to 95MB/s Read and 90MB/s Write speed with UHS-I, Class 10 and U3 compatibility."
It should serve you well for quite a while I'd imagine. Even I'm tempted to get one right now.
