8Gb Micro SD Issues

Hello all, I recently upgraded to the ATT Fuze and then installed an AData 8 Gb MicroSD card. The issue is sometimes the phone will not detect the files in the card. So if I restart my phone everything works fine and the phone sees all files in the SD card with 80 mb used. If I restart again the phone takes a long time to view memory of the storage card and then shows nearly the entire 8 gb used. File explorer show the folders but none of the files in the SD card.
If I remove the MIcro sd card and plug it directly into my laptop then it shows the actual space use and al the files correctly.
Anyone see this issue or how to resolve it. I have already replaced the phone once. SD card works perfectly when used in a laptop.
IS THIS A PROLEMWITH THE PHONE OR THE SD card.
Please help

Why don't you try re-formatting the memory card?

If you've replaced the phone and you're still having the problem, I'd say it's the card.
I use a SanDisk 16GB MicroSD in my Fuze and have never had any problems with it.

I have reformatted the card multiple times using both vista and Xp and still the same results. The card works just fine on my laptop. When I put the card in my phone it does not detect the card till I soft reset the phone. After it comes up, the phone will see the card but show space used as the entire 8 gb even if the card is empty.
I have ordered a new Kingston 8 gb card. Hopefully that will work

Sometimes there are compatibility issues with certain cards. I use a Sandisk 8gb card and it works well. TP reads and writes quickly to it. Try this other card you ordered then adise results here. Good luck.

HTC recommends Sandisk.
I use sandisk 8 Gb Micro SHDC Mobile Ultra with the Tyynt sdtune up cab!
Suggestion
Format the card sell it and buy a real sandisk ;-)

Yea! will try the Kingston. What is the sdtune up cab file. I could not find such a file.

I too
Hi, i have the same issue with same A-DATA SDHC 8GB Class 6. On PC everything is ok, but when i put it in TP (no branded) PDA didn't recognize it. I reformat it 10+ times, same. I make some experiments and realize that when on the card i have to 2GB files work fine, but when i exceed that limit the card stops to mount in file system of TP. I fill the card to max with some stuffs and place an image file, then try to flash the phone with it, the strane is that the phone is flashing ok, but after flash and hard reset the card didn't mount at all. If i change the image file i can flash again, but in file system i haven't card. Very strange. I use few roms ot NRZ28. Do you think that the problem is in any dll in rom or the problem is in card. Becouse bootloader see and use card, but the system didn't.
p.s. Sorry for bad english.

My Kingston SD card works. The only difference I can see between the two is that the AData is a class 6 while the Kingston is a class 4.
maybe the Fuze has an issue with class 6 cards?

I am using the ADATA 8G MicroSDHC memory card without any problem for my HTC Fuze. This is a Class 6 card from Newegg.

Yea, I had bought the exact same one! Dunno why it didnt work for me!

i am using an 8GB Adata microSDHC card from Newegg.com and my HTC Fuze will NOT see it. I have tried everything I know (very computer knowledgeable). Checked the reg settings, etc. but it will not ever see the card even after reformats and reboots. The card works fine in laptop and other devices, but not my HTC Fuze... ???????

I had big probs with my 8 gb sandisk: Files and folders were lost after a time... i formatted with a lot of utilities, nothing helped now i use kingston without any probs on my TP ...

I purchased DSE 8Gb card, like you could see it, reformat it & everything worked a treat on the PC, but when putting into the TP it was a very different story!
Sometimes it would see it, sometimes not, very hit & miss affair without any reliably repeatable circumstances, so took it back, tried another one - same issue, then sucked it up and went to purchase a Kingston one (5 bucks cheaper)... it worked first time and haven't had (touch wood) a problem yet!

Mariobg, I am in the same situation you are. I am using NRG Energy Rom 2.0 4/14/09. I am having the same problems with my A-DATA micro SDHC 8GB Class 6. I also own a SanDisk 512 MB micro SD card that works no problem. I will try flashing to a different ROM to see if that fixes it. Did you ever solve the problem.

Adata issues on rapahel
Hi there , i have the same problem with this &*^&*%$ Adata card on my raphael.
Rom : Elite rc3
Tried Hard Reset
Tried Soft Reset
formatted it untill it was smoking.
Learned one thing with this....first read...then buy.

Well I tried several different ROMs and still no success. i ended up trying the memory card in my friends HTC Fuze, and it did not work either. He had a 4 GB micro SDHC A-data card that works great. So I tried his card in my phone, and it also worked great. So, it appears that the 8 GB A-data card is defective. I am going to RMA it tomorrow.

But, unfortunately, it did not solve my problem.

I have a Class 4 Kingston 8GB MicroSD that was in NTFS format. My HTC Fuze couldn't see it until I format it in FAT32. Works now .

8GB Transcend SDHC not working in Fuze

Ok, so I just bought an 8GB Transcend SDHC Class 6 from Amazon. My Fuze (with default ATT rom) won't recognize it, but my friend's Verizon Touch Pro does. It also works in my laptops SD slot with the adapter. I tried formatting it, but my phone still doesn't see it. I tried googling for help, but the only thing I found is wm5/6 having issues with SDHC. The Fuze is supposed to be compatible, right?
Is there anything you guys could would suggest? I found a SDHC.cab file, but it doesn't do anything.
-nate
also, my 2GB Kingston works fine.

I have found Transcend SDs to be iffy.

I've been using a Transcend Class 6 microSDHC card that I purchased from Newegg (with miniature USB reader) since day one with my Fuze, hasn't missed a beat. Sounds like you may just have a faulty one.
This is what I have: http://www.newegg.com/Product/Product.aspx?Item=N82E16820208460

same problem here, please help ..........

Using a Transcend 8GB Micro here no probs at all!! Been using for months I'd say

JFlitt

So here's what I tested:
I bought 2 of the Transcend 8GB C6 cards.
Neither card worked in my Fuze or my bosses Fuze.
Both cards worked in a Verizon Touch Pro.
Both cards worked in multiple Verizon 6800's.
I found a friend with a Trans 8GB CLASS 4 card, it works in my phone.
I sold one of the class 6 cards and traded the other to my friend.

Oh also mine does say C6 on it, or more specifically a 6 with a C around it!
Thanks
JFlitt

Sandisk is the only way to go..pretty cheap on Amazon

You know just for the hell of it, one of you guys w/ the 8gb card should dl and try the Panasonic SD formatter program. Google it. I have one that just says V2.
I had weird issues w/ a 4 gig card, reformatted it numerous times, w/ numerous programs nothing worked until this panasonic program i found.
SDFormatter V.2

My 8GB Transcend Class 6 works great in my FUZE. What I found interesting is that I bought an 8GB Transcend in November for $16 and another in January for $15 but now they cost $21! How does the price RISE $6 in 6 months? I think there is something fishy going on in flash memory prices. They had working 32GB prototype cards a year ago yet they still are not out.

it could be putting the storage card at the bottom of the list in file explorer. you made sure it wasnt there by looking at the storage card tab under memory settings right?

Trying it Now

I've got the same card with the same problem. The card actually worked for the first time, but after flashing a new ROM onto the device, the storage card was no longer accessible from the phone itself while it is from card reader. Formatting does nothing.
I had an issue like this once with SD cards on a Dell Axim but it turned out to be the fault of the WMDRM folder--which isn't the case here since the card is empty now.
Is there some other method in which the device locks the card?

Just wanted to throw my two cents in. I bought two Transcend 4gb class 6 SDHC cards, both of which worked find in my computer and camera, but neither worked in my Fuze. I ended up buying a Sandisk card which is working famously in my device. However, it is only a Class 4 card... Hey, as long as I can save and playback video to it without interruption, I'm happy.

So it stopped working after flashing a new ROM? Have you tried going back or flashing a different ROM? It could be a problem with the ROM if the problem started happening after you flashed a new ROM.

I've gone back to that ROM with no success and on to different ROMs with no luck. Changing Device ID doesn't seem to help.
I will try that format utility when I get home.
My 64MB Sandisk works fine however.
The only way to access the 8GB Transcend card is to install wm5torage and use the phone as a reader, so it's not a hardware issue. The storage card itself cannot be viewed in File Explorer/TC or through ActiveSync--basically WM refuses to acknowledge its existence.

No deal with the Panasonic format program.
I'll just use the card in my Garmin for MP3s instead.

The card just arrived from Amazon for me, and it isn't working. I should've searched this up before buying the card. Still no fixes?

i have trancend microsdhc class 6, 8gb and not working in my raphael (asia wwe stock rom)
is there any chance that upgrade rom to the newer one / flash custom rom will fix this issue? panasonic sd formater didn't help.

i have this card 1month and it work ok for me. one day card crash i get new (same) but device don´t see this card. i try new rom, panasonic sd format but no change.
i try 8gb sandisk class 4 and kingston class 6 and this cards works ok.

Moto G 4g LTE - Sandisk ultra 32gb microsd card won't mount

I picked up the Moto G 4g LTE version recently hopping on the fact that they added an sd card slot. Anyway, I purchased this http://www.amazon.com/SanDisk-Ultra-MicroSDHC-Memory-Adapter/dp/B007XZM6VG/
microsd card hoping for some nice expansion. But for some reason whenever I insert it it says damaged sd card, tries to format it, then says blank sd card, and basically loops this process. Now here's the weird thing, this sd card works fine (can read and write) in other people's phones, but just doesnt seem to work in mine!
I even tried my friends 32 gb microsd card and it worked (it was a slower class 6 varient),I tried *my* sd card in that persons phone, and it mounted and worked fine, the sd card works in my PC also.
I'm wondering if I need a slower speed card? Maybe class 6 or 4. Because I read up on another guys problem on here, his is freezing but he got a slower 32 gig card and now it works without a problem. I know he was having a different problem but I'm wondering if the phone is having an issue with class 10 cards.
Anyone having the same problem or have any idea what might be going on?

Hi,
As I mentioned on the "other guy"'s topic, I experienced this kind of issues with my previous phone, which were entirely solved by replacing my 32 GB Sandisk class 10 card with a 16 GB Samsung class 6 card. AFAIK, fast cards may cause malfunctions with some Android phones, because of the access response times.

Had the same issue. resolved by getting a different brand and lower class. all issues resolved.

I'm using this card bought thru Amazon for 17.99 ------Samsung Electronics 32GB EVO Micro SDHC with Adapter Upto 48MB/s Class 10 Memory Card (MB-MP32DA/AM)------
I have had 0 problems with it and high benchmarks, I use to use Sandisk but after multiple problems with multiple cards over they years I have completely abandoned them for Samsung and have yet to have a problem.

The problem comes from that, some cards won't fall back to lower performance level and thus causing issues for the device that it is inserted in.
Some devices does not have problem with that tough.
Another reason could be the file system used, but that's less likely, although not very rare.
And one more thing is that brands like SanDisk, Samsung, Kingston etc are the actual developers of the SD technologies and sometimes you may get a product that is using newer technologies, which often causes troubles.

I purchased same Sandisk micro card from Amazon as OP did. I got same results. It is sitting here on my bed with RMA on it to back to Sandisk. Just got a new speck sheet which was posted from the motorola forms that says the following:
Micro SD UHS-1 "The card will work, BUT the Moto G 4F/Lte WILL NOT SUPPORT UHS 1 - SPEEDS.
So it appears, a slower speed card is in order. I just had to purchase a Samsung 16 gb class 6 card. Would rather have had a 32 gb but could not find in class 6.

Random and Sequential of my 32gb Samsung Evo UHS-1 in my Moto G LTE using A1 SD Bench

Thanks so much for the input and advice guys! I was too impatient to order another sd card and wait for it to ship so I went and bought a random 32 gig class 10 card from a brand i've never heard of called "Monster digital" and it works perfectly. So I'm not sure what really fixes it, if it's a brand thing or size or speed or what. But my change from my non working sd card was Speed: UHS-1 -> Class 10, and Brand: Sandisk -> Monster Digital

Regarding the SD card issue. I tried with three separate phones with a 32gb class 10 and and a 16gb class 4 -- failed on two of them, but works fine on one of the phones. So there is definitely a build quality issue ( and/or difference ) between the phones, aside from the mentioned 'supported sd card class.' Both of these cards work fine on all other devices ( pc/laptop/tablets including old SD card readers with adapters )

Wanted to give an update. Tested with four devices now ( 2 black, 2 white ) and First one ( white ) worked, next two did not work, but the fourth device ( black ) it worked to detect 32gb sandisk without fail. So there is _definitely_ a difference between them from device to device -- maybe even assembly line quality control issues depending on week of manufacture, who knows.

Very interesting (and puzzling). Do they all run exactly the same version of Android? Are they all exactly the same model (eg. XT1032) and the same internal storage capacity (8/16 GB)?

Oops, Moto G LTE is 8 GB only, sorry.

Yes.. exact same model/capacity and OS, all ordered within the same 1 week period ( two being RMA )

Can verify that the XT1045 4G LTE performs very well with a 64GB SDCard inserted internally, ALSO..with a 32GB MicroSD card inserted into the USB / Charge port..and runs both very well, and with both cards mounted..

I have a Moto G LTE on order, and am wondering if the various problems people are seeing are due to the file system used on the card: exFAT or FAT32. I would assume the newer SanDisk cards are formatted with exFAT. Does the flavor of Android on the phone support exFAT ?
Another issue I've found in the past with some other devices and ROM's is that if the card is formatted as exFAT, it might need be set up as a primary partition and not a logical drive (using MiniTool or some such).
But we'll see what happens when the phone & card actually arrive

As far as I'm concerned, my cards were all FAT32-formatted, both the malfunctioning SanDisk and the Samsung that worked well. Nothing to do with exFAT vs. FAT32 then.

Exact same 2 cards ( check my previous post ) , tested on 4 (four) MOTO G LTE , 2 Samsung and a Camera and a Tablet worked only on 2 of the MOTO G LTE's + all the other non motorola devices. It cannot be the formatting or even the make of the card if it's a compatiblity issue.

I am getting 'Removed SD card' / 'SD card removed, Insert a new one' error by using exact same Samsung 32GB EVO Micro SDHC. I could not format it by using Moto, so I did a full format in my PC, Same result. The microSD symbol is UHS-1 (one capital U with '1' inside') - matched Amazon's picture.

Try a slower card (class 6 fort instance).

My XT1045 and sandisk ultra 32gb card both arrived, and they seem to work together just fine. Android version is 4.4.3. Card came formatted as fat32. Promptly unlocked the bootloader in hopes of flashing slimkat at some point

Just got my moto G 4g delivered today and My 32gb Sandisk Ultra (which I had for 2 years in 6 different phones) won't work. looked it up, saw this thread and I'm kinda sad that I have to buy a new sd card for this when I paid a premium to have the ability to use a sd card in the first place. Nonetheless, I'll take the safer route you guys talked about and try for a lower class speed. Just ordered a samsung 32gb (not the evo model) class 6 from amazon for about 19.25 after tax. it should be here on the 25th I'll let you guys know if it's a good one to use. I knew kit kat didn't play nice with sd cards but this is ridiculous.

[Q] 128GB MicroSD support, problematic?

H2testw verified card (passed) caused my MT7-L09 to reboot spontaneously over and over again until I remove the MicroSD card. This started yesterday probably after I installed a few more apps. These have since been removed. Card has about 62.4GB out of 119GB, used 56.5GB. Formatted to exFAT on Windows 7. Working fine for about 2 weeks until yesterday.
I bit the bullet and hard reset the phone this morning. Clicked the MicroSD card back into the slot and loh and behold, it started to restart again!
Anyone have the same problem? Using a Sandisk SDXC-UHS-I card here. Its not hardware fault with the MicroSD card slot because replacing the 128GB card with a 64GB card presents no such problem.
Edit: Inserted the card into my Note 3. Card presented no problems at all.

Have u solved this problem yet? Im thinking of buying the 128gb sandisk ultra with the 48mbps read speed to be used in the Mate 7. Is this the same sandisk microsd card you are using?

I am proud owner of MT7-T10 who is having exactly the same problem after inserting newly purchased 64GB Sony UHS-I Class 10 microSDHC Card. In fact, I actually bought 2 of these type of sd - I have not tried replacing it with my wife's sd card - must do this test to flag out DOA (defective on arrival) sd card.
It was working just fine until the sd card is half full. I tried factory reset and reformatted the sd card and the issue reoccurs after transferring all my data back to sd card (i have not tried without removing sd card thou). Since the unit was still under warranty, I took initiative and brought the MT7 to Huawei service centre and even demonstrate the issue. They happily replaced with a new unit but even that had the same problem out of the box. I also asked if they have any list of compatible sd card supported on MT7. The front desk simply mentioned that it usually kingston, but there isn't any black & white papers or sites to support that statement.
I also came across forums emphasizing to use only popular branded sd card and sandisk was one of them. Since you are having the same problem even with sandisk, I won't be surprised if kingston too have this problem. Or may be it is MT7 sd slot defect by design. :fingers-crossed:
As overall, I'm happy with MT7. Extending the storage using sd card would have been a added advantage but this is not the case at the moment. :good:

I did it twice but the problem persist.

i experienced that before, but in xperia and old s3. It happened due to runaway media-scanner process. somehow it kept running scan all the time from the start. It didn't cause bootloop / restart, but it literally hanged my phone that time

I'm not 100% sure but i read somewhere that Huawei recommended to use 32 gig capacity Max. Or you could experience bugs.

My phone never rebooted, I have a 128 GB SanDisk Class 10 sd card. But after like a few weeks or months I got a sd card error and soon after that I couldn't access any files on it.
Only rebooting solved the issue, but once I got it it would occur more often and often, sometimes every 2 days and sometimes multiple times a day. Formating the SD card made it work again for a few months until it started all over again.
I formated it to different formats (in windows), I also formatted it with the phone itself, nothing helped.. I'm constantly running out of space now because I only store my music and photos on the sd card.
I never tried a different sd card long enough to recreate the problem, but I used this sd card for a few months on a different device.
If someone fixed this please help me I'm so tired of this :crying:

I have a 128Gb Sandisk in my Mate 7, runs with no issues at all. Maybe clean your contacts?

To be honest I never tried it lol, but if rebooting the phone solves the issue I don't understand how dust or dirt could be the problem. I will try it anyways, maybe it works :cyclops:

Cleaned the sd card and the sd card slot as good as possible, but after a few days I had the same problem again... Maybe my sd card is broken but I can't really test it so I guess I'll live with this forever...
Just now it came to my mind that I could've bought a fake SanDisk card, even though I got it from amazon. I will test it tomorrow I think.

Maybe.
How is it formatted? Probably most compatible to format to FAT32.
I have a 64Gb card in an old phone that was supposed to take a maximum of 32Gb and it works fine when formatted the right way.

It is formatted exFat right now, I formatted it quite a few times since i got the card so I don't know whether I always had exFat or not. I'm checking the SD card now for it's real capacity, with 100 GB left it will take 8 hours, but if it's really a fake card it should cause errors way earlier I think. If that's not the problem I'll wait until I have time to flash KangVIP, then I'll re-format the sd card and do some cleanup while I'm at it.

i bought a 128gb samsung evo+ sdcard and working great so far
