Hi.
i've been using my samsung galaxy tab 2 7.0 (GT 3110) with stock JB 4.1.1, rooted and running Smanager with "internal2externalsd swap" script.
it had been working fine for 1 week, yesterday i was playing alien vs predator which i didn''t like and erased it. i go to sleep, wake up, and now the tablet says the microSd is damaged, but does not let me format, neither in my laptop (it does detect it, but when trying to format it tells me to insert the microsd).
it is a MicroSD 32gb class 4. (apparently no one brings class 10 to mexico).
This is the 2nd MicroSD i screw (yet the previous to this one, which was replaced by warranty, there was an obvious cause, because i did something wrong and the tablet stucked and it would auto reboot many times so the microSD was under lots of pressure, and besides i had the memory swap script running alog with "Link2SD" app so it was like a constant battle between them i guess)
anyway...
i do not want to screw another one as i doubt they would replace this with another one as obviously my tablet is the problem.
could it be the script?
could it be the fact that i use to force stop some apps?
could it be that i deleted some stock samsung apps like the game center and that stuff?
there was really nothing to suggest a malfunction :S, and i've used temporarily the microSD of my cellphone (8gb class2) and no problemwith that one :S (used it 2 weeks while waiting for the replacement of the first one, in those 2 weeks i formatted the tablet, started clean and had only the script running, no problem at all)
what do you guys think and suggest?
Every time i read those threads, i think that samsung has anything include in this tab, that destroyd every sd card, that is not from samsung.
Its not the script, its the tab, it doesent like non samsung sd card's

really? damn.
i tried to find similar threads but no luck :S.
it will be hard to find a samsung microSD here in mexico =(.
is it really my only option? no way to prevent this? i can't find any info anywhere =(.

You're really suggesting this? I highly doubt this is the problem. I've been running a non-Samsung SD since the beginning. The problem is with the script. Try running a higher class SD or stop running the script.

The problem is the microSD card.
You don't need a higher class microSD card to effectively utilise the swap script. Neither does the swap script directly damage the card.
What happened here is likely a poor quality or defective card that could not handle the increased R/W when using the swap script.
Some may argue that there is increased wear & tear on the microSD card when using the script, but the microSD card, regardless of class, would last a long time before failing.
There have been many reports of Sandisk cards failing in Samsung devices. Sandisk has already acknowledged defective batches of cards. Go google to learn the specifics.
It was a Kignston 32GB Class 4.
i am planning on getting an AData 32GB class 10. (the only class 10 i could find anywhere, there are Kingston also, but not trusting them again =/, i have and externa HD from AData that has been working excellent for about 2 years)
probably it was defective.
do you guys suggest more a class 4 or class 10 for the increased R/W you mention?
i've been reading and aparently class 10 has a faster write speed but less overall speed so i got a little bit confused =(

I would argue that the script does cause the issue. He's already been through 2 cards, and they weren't SanDisk. The tablet is not designed to run everything from external, so it will cause more stress.

Well, if you said that the card failed after a year or so, I would say it could be the high levels of wear & tear due to the script.
But, just a week ??? Come on, that's ridiculous to think that the script could induce such shocking levels of wear & tear on the card to cause it to fail in a week.
Very likely it is a poor quality or defective card.
i agree with jaydaman.
i guess it's worth to add that during the 2 weeks i waited for the replacement of the first MicroSD card i used a Kingston 8Gb class 2 (that was already on my cellphone) and had no problem during those 2 weeks. so maybe it was defective :S.
guess i'll get the AData 32Gb class 10 and hope for the best =/, it's really useless to live without the script as apps wont install or run directly from the "external sd", so that limits the number of apps i can have.
=(

I agree, i have been storing apps on my card since i bought my tab, either with the script, or folder mount,with no prob. Besides, older phones store apps on sdcards almost exclusively, because of small internal memory.

Flash memory like microSD cards are being mass-produced in greater volumes than ever, especially with the popular brands such as Kingston & SanDisk thanks to the proliferation of smart/mobile devices.
It is thus likely that there are more 'lemon' cards with every batch.

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
http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=2074251
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?

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.

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'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.
Alright so I recently bought a 32gb sd card so I could put the rest of my music on my phone. And I transfered all my music on to it. Put it in my phone. And all of the sudden half of it is deleted? So I thought I was crazy and put it back in my laptop and sure enough half of it wasn't there. So I transferred the music again by selecting all the music instead of just moving the folder.. Waited till it was done. Checked to make sure it was all there and put it back in my phone.. Sure enough half of it has been deleted again. I'm on Embryo 6.5, I use player pro as my music player, and the card is a SanDisk 32gb.

I've moved a lot more to different storage devices and never had a problem. Like I said, it disappears when I put the card into the phone. I did it again and threw it in my tablet this time, and it all showed. It's definitely a phone issue. The card is fine.

Both. The music files are gone. It shows them gone when I put it back into my laptop also. As soon as the card goes in the phone, it deletes them for some reason.

Yep, sounds that way. There is a huge problem with counterfeit and sub-quality SD and Micro SD cards these days. It is so huge of a problem that many of the cards that are sold from Amazon, E-bay, and Brick-and-mortar stores are fakes. Its so hard to buy a legit SD card these days because the fake or altered cards are actually in OEM packaging or at least it looks very similar to OEM packaging. Many times defective cards or lower capacity / lower class cards are being physically altered to appear like more expensive cards. It seems to mostly be a problem with the class 10 cards. Sometimes people don't even know they are getting screwed because the cards usually work for the purpose that they use them for, but if checked (and some never do) the actually specs of the card fall way short. Many of these cards fail quickly as well. To add to the problem, certain phones "like" certain cards better than others. So one card may work well, and another card (same manufacturer, class, and capacity) doesn't work well at all. It's a crap shoot even if the card is good quality and legit. So, sometimes you just have to go through a few before you can get one that works well or just get lucky with buying one card that happens to work well. I purchased 2 cards that were counterfeit before I learned of the problem. Both were supposed to be 32 GB class 10 San disk cards and were marked as such. One was from Amazon and one was from Radio shack. I noticed a problem with both because while I was taking video in very fine mode, the phone would lock up when recording to SD card. Both fine and normal video modes worked and very fine video mode worked with no problem when saved to internal or when saved to another SD card I have (16 GB class 10 PNY). The problem was that both of the San disk cards were recording data at a rate that was too slow for very fine video and certainly way slower than a class 10 card. So, they were fake or altered to appear to be a better class card than they were. Just check Amazon reviews for most 32 GB class 10 cards (manufacturer doesn't matter) and you will see several benchmark reviews that show how bad these cards can be. Good luck, the best advice I can give is never trust an SD card with important info and ALWAYS back all data up...TWICE!
That's way when it comes to these things I always buy after I make sure I can return a defective item..
A bad sd card doesn't explain why it works fine in my tablet. Then music deletes when I throw it in my phone.

It was definitely Embryo. I switched to Rogers latest CM fix and everything is working fine now. All music is there, nothing is deleted randomly.

I have tried both a 64gb and a 32gb micro sd card and if I try to save or backup my documents on it sooner or later a few weeks down the road my Note Pro 12.2 reports that I have a corrupt card. I never take it out so that is not the cause. I do not have any apps installed on the card. I am not rooted.
All I am trying to do is keep my music, videos, pictures, and a copy of word and excel files on a micro sd card but I have no trust that my micro sd card is going to work.
I have formatted these cards using my Note Pro. I have formatted these cards using my Windows PC. But several weeks down the road I get the corrupt disk error... please reformat!
Is rooting the answer?
Any help is appreciated.
Sounds like a bad card to me. What brand is it?

This usually happens with low-class or cheap-brand cards.
In general you're best off only using class 10 or above cards by Sandisk or Samsung. Anything else is highly unstable.
I have a San Disk Class 10 64gb but my other card is a PNY Class 6 32gb. I guess I'll look at getting a Samsung? I believe I had read somewhere about this device not liking 64gb cards? Or maybe I read something about it not allowing files to be saved to external storage. Something Samsung was doing.
Anyway thanks for the input. I would like to use a 32gb card as I really don't need 64gb so if my PNY isn't going to work I need to get something that will.
How does this card look?

If that samsung is as fast as it's rated that looks like a good card.
I'm using the Sandisk Extreme Plus 64gb but have only had it for a month and a half. So far no issues but I wonder if it too will be a time bomb.

I ordered it since it was only $27 & I had a $25 gift card.

There's no issue with 64GB cards. There's no issue with 128GB either. Some of the older devices had issues with SDXC UHS-I cards, but that was over a year ago.
There is, however, an issue with Android KitKat no longer allowing non-stock apps to write to the SD card. That's Google's doing. It has nothing to do with corrupt cards.
Samsung and Sandisk cards are both excellent. Just make sure they're class 10 or higher.

What is the best method to copy delete movies to/from my micro SD card? Should I unmount it and remove it or should I power off my tablet and remove it. Or will it be better just to copy them from a USB stick to the card while the card is still in the tablet? I'm hoping to keep 10-15 movies on my card and swap them off to put more on probably every 6 weeks and I want to know which way is the best way not to harm my card.

Unmount the SD card through Settings --> General --> Storage --> Unmount SD Card.
Or connect the tablet via USBcable to the PC and copy it onto the SDcard that way. (It loads as a network device in explorer)
I've got 11 films, two shows and a handful of concerts on my MicroSD and swap regularly, I usually use one of these two methods.
For me, I use a MacBook Pro which for some reason does not allow me USB 3.0 connectivity to the tablet (driver issue I'm sure but try as I might I have never gotten it to work). I therefore use a USB 2.0 cable and Kies to copy files to the tablet that way. I'm able to pick the external card as a destination and transfer at USB 2.0 speed.

Thanks for all the help everyone. Hopefully with the new card coming Wednesday my problem will be solved.
I have and use a 64GB SanDisk Micro SD Card on my P900 and can open, copy, move files from and to the sdcard using samsung's stock file manager (My Files) without any problems.

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.

Card has been used in 3 Samsung phones. Never had this issue before. Is not a fake card and not disabled and packages

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
Write speed: 10:78 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:
Read 1692.00MB/s
Write 14.81MB/s

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.
