[Q] Strange problem with 32 gb card

Ok, so I'm going crazy now, but I just can't figure out what's wrong with my card.
I bought a new 32 gb card. I know, I know, you're gonna say it's a fake card, but it's not. I tested it with H2testw and it fill up the card with 32GB of random data.
So, here's what's happening.
1. The card came formatted, I just swapped it with the old card and the Tab recognized it without problems.
2. I took it out and copied backed up files from the old card onto it.
3. When I put back the card into the tab, only a few folders were visible and other data that was copied and visible via the card reader was no where to be seen on the tab.
4. Then I took it out and tried repeating the process - same thing.
5. I tried quick formatting the card through the PC, and tried everything once again. Now the results were different, but again not all folders were copied.
6. I tried formatting through the Tab. The format went fine. Then I tried copying files through the USB cable (mass storage option). That also went ok, but a few of the files could not be opened. Scanned it with disk check and automatic fix error option.
7. Back to PC, did a full format with a Panasonic sd card formatter. Ran H2testw. No problems. Put the card back, re-rooted the tab (since I started suspecting it could be somehow related to this).
8. The card is back in the Tab, but it's still showing some strange behavior, such as folders dissapearing or files not being readable.
Anyone have any idea what to do? I would also like to note that the card works fine when in my reader, I can copy files to it, open them directly from the card etc. No problems at all. But as soon as I put it in the tab it goes crazy.
P.s. The tab is rooted, firmware is out-of-the-box. I have app2sd, but I didn't put any of the apps on the old card, and all apps work normally with or without the sdcard.

I dunno. Bad card? Or maybe just incompatible with the Tab?

just wait android 2.3 to fix this program
Sent from my GT-P1000 using XDA App

the card is fake,
i had this a while ago, i could copy files over fine and the files showed in the file structure in windows explorer. BUT if i restarted the computer loads of the files went missing, i then found out the 32gb card was in actual fact an 8gb card but some trickery makes it look as if you have copied 32gb over. the best way to test it is to copy over say 25 films at 1gb each, see it copy over, restart your computer and then see how many are left after the restart, you will then see how big your card actually is!! Sorry to be the bearer of bad news but i hope you can send your card back and get a full refund.
I have tried a genuine 32gb card from expansys which works correctly in my galaxy tab (JM6 firmware) and my x10i.

AFAIK only Sandisk and Kingston make 32GB microSD cards now.
I got my Kingston 32GB card from Newegg and it works great in my Tab.
Where did you buy your card?
I would not dare to buy SD card from eBay or from a store that has no good return policy.

[Q] Have I Killed My SD Card?

I purchased a new SanDisk 32GB microSDHC card for my Magic a few weeks ago. As of the beginning of this month, I started noticing some strange things happening like the card being set to read-only at random. I first noticed it from the camera app where it stated that I needed to insert an SD card before using it. I checked using Root Explorer, and strangely enough it was mounted as read-only. I mounted it back as R/W, and everything seemed fine...or so I thought.
A few days later, I was gonna send those pics that I took with the camera, but they were gone and nowhere to be found on my SD card. I got suspicious so I took a few test pics after (again) having to set the SD card with R/W permissions using Root Explorer. I checked the card, and the pics were there, but as soon as I tried to send them via MMS, the files disappeared. From here, I put the card in my PC's card reader and copied a random file to it. No issues with that, so I put the card back into my phone and that file was gone. Scratching my head some more, I put the card back into my PC and copied another random file. Then I refreshed the folder view within Explorer, and the file was not there. Seeing that I could read the files on the card, I feel that something strange was going on, so I made a backup to my PC. The files copied fine, and I can see the contents on my computer, so reading from the card isn't an issue. I, then, attempted to reformat it from the computer. Windows complained that it was unable to format the card, so I thought I'd go with something a little more refined when dealing with partitions. Using Paragon Partition Manager, I was unable to reformat without first deleting the partition already present, so I did just that. However, after deleting the partition, it gave an error saying that this drive cannot be formatted. Having gotten really frustrated with this issue, I decided to try out GParted on my laptop. I put the card in my card reader on that and ran GParted. It recognized the card, but showed that it was still partitioned...leaving me to believe that Partition Manager didn't actually delete the partition as it said it did. Didn't worry about that too much, and went ahead and deleted the partition through GParted and reformatted to FAT32 with no errors whatsoever during the process, and everything seemed to work fine. However, the used file space was exactly the same as it was before starting this process. I slapped the card back into my PC, and sure enough nothing has changed.
It now seems that the state of my card is somehow "frozen". I can read the files already existing on the card, but nothing can be written to it. The only thing that I did differently with this SD card, in comparison to any other card I've used, is using Swapper (org.azasoft.free.swapper) to create a swap file on my SD card that appeared to work fairly well until all this happened. Though maybe a 1GB swap file wasn't such a great idea, and most likely unnecessary anyways.
I've had a card die on me in the past, but just because it was old. Though, it was completely unusable...couldn't read or write from/to the card, respectively. So being able to read from the card is quite new to me, and I'm not sure if I've killed it, or if (possibly) there is a chance for revival. Normally, I wouldn't worry about it too much and just have the card replaced, but due to the highly sensitive data currently present on the card, that's completely out of the question at this point.
Any insight on this issue would be very highly appreciated.

I would see if you can get it replaced. If you can't, and their is sensitive info on it, completely destroy it (break it into several pieces, blend it, then use fire) and buy a new one.
Seems like you've done everything I could think of. So I'm not sure what to suggest to try and fix it. Maybe try to dd if=/dev/zero of=/dev/whateveryoursdcardiscalled and then format?
you should really encrypt sensitive data so you don't have to worry about it when problems occur

tl;dr
However, it did seem like an issue I had with an SD card back when I was trying linux distros on USB sticks. My 16GB was turned into an 8GB one. That sucked LOTS. You know what fixed it?
My camera
Yeah, I put the SD on it and pressed Format. It automagically partitioned it and it's working correctly as we speak ... try other devices, such as handycams, cameras, mp4s, iPhone/iPod & such. They can do what Linux + gParted and Windows can't =)

SD Card

hello, so after recently using WP7, I've found myself unable to use my SD Card
Windows doesn't recognize it (That sd card formatting tool that's in several stickies, DISKPART, device manager, etc.) (I've also used 2 MicroSD -> SD Card adapters in an attempt to fix)
my phone doesn't recognize it (WP7 will use it) (Magldr says it clears the MBR, and I've reinstalled WP7 in an attempt to use the sd formatting tool, but no avail, and CWM fails to recognize it)
I've also installed busy box on my phone and tried to fdisk it, I plugged a 1GB microsd card I have into the phone while in android, used 'mount' got the /dev/ location of the sdcard (/dev/block/void/179:1) and swapped cards, but it won't open the stock 16GB
any ideas XDA?

I had this Problem one time too. My Solution was to put the 16GB Mirco-SD Card inside the SD-Adapter. After that i plug this SD-Card inside my Digital-Camera ( Powershot G7 ) and make a "Deep Format". After that, everything works fine...
Maybe this helps!
Happy Christmas,
Michael

Thanks for the tip, I've tried it on one camera but it was a rather crappy one and it just froze the camera o.o
going to try with my nicer camera when I get home
--edit--
eek. tried it on a PowerShot Aesomething and it jsut said memory card error and greyed out the format button, might be time for a new card, oh well, I could go for a higher class on android since it lags my apps a bit

SD Card showing Unsupported and Unmounting automatically on Android, fine in laptop

Hi,
My Sandisk Ultra 32GB microsd card is not getting mounted on my Moto X Play from yesterday on. It was working perfectly before that.
Problem in Detail: Yesterday when i tried to play some music only I realized that its not getting mounted. I tried removing the card and reinserting it. But it's not showing up any notification. When I went to 'Storage and USB' settings suddenly after reboot, its showing 'Unsupported' for a minute and is getting unmounted automatically.
Possible Cause: One of my friend connected my phone with USB cable to his laptop day before yesterday for transferring data. I dunno exactly whether its infected or he didn't eject it properly.
What all I Tried: Initially, I tried connecting it to my laptop using Card Reader. Fortunately, everything was fine inside the system. The file system FAT32, all the data it had, and no memory was unallocated. Afterwards I did a quick format and a complete format as well, with file system FAT32. Both didn't help anyway. Then I installed mini tool partition wizard. But haven't done anything with that yet.
Kindly help me with this ASAP.

Can you use your SD card with the phone ?I have the same problem - my sd card is not recognized by my MXP. There was some speculation that the SD card slot is not working properly or just damaged however all SD cards I have are working fine just nor with my phone.As of today there seems to be no fix to this bug.

I have tried this SD card in my friend's phone and it is working fine.
Afterwards, tried formatting the card from that phone, my laptop, (quick & complete with different names) and the tool "sd card formatter" (erased everytihng).
I even tried a factory reset of my phone.
Nothing helps. Really frustrated

try the slow format sd card option from pc...

SD card corrupt issue

Anyone facing corrupt SD card issue on moto g5 plus ?, This happens to me each and everytime my phone got switch off due to low battery and when I boot it again my SD card got corrupted...

Still on first day of ownership with device here. Android currently reports a corrupt SD, and I recall reading that there's two options for storage under Android 7. The traditional, of keeping the SD card as a separate file system, and I think the updated handling has to do with encryption.
Will revisit post if I encounter similar issue, regarding low battery.

It's natural for the first time, but in my case it shows corrupt SD even after I ve already formatted it with my phone (Only if phone switches off due to low battery).

Well It gave me corrupt card error on the 3rd day of use, all I did was just restarted my phone and when it turned on It show Sd card corrupted. Although my PC was able to read it. Then i took a backuo, formatted card with phone and restored data. Hope I don't see the error again.

My card got corrupt yet again after a normal switch off and on process.
It's a 64Gb card. Don't know what to do.

Here the problem comes..., it's a software issue I guess, BTW there is a workaround. Connect ur SD card to a computer and scan it for errors(apply fix if needed), after that test u can use it as before. I hope it helps :good:

Tried everything but not this, yes I also believe it's a software iasue coz data stays intact after it says corrupt. My 1st workaround is not switching off the phone.
Thanks

Same issue here. I bought my Moto G 5 Plus 3 or 4 days ago. Have a Sandisk 32GB (Class 10) MicroSD formatted as Internal Memory. I restarted the phone several times and everything was fine. Till one moment I wanted to take a picture, but the motorola photo app was crashing every time I wanted to take a picture. I restarted the phone and the MicroSD card was corrupt. The MicroSD was basically new, never used, only inserted once in an other phone, but not even used once to store anything. I really hope this is a software problem and not a hardware problem, and that they will fix it..

Was this ever fixed?? Im buying the phone and getting on Friday

Well, no OTA updates so far, so I guess no fix. I'm using my SD card as external storage (Not formatted as internal) and I had no issues so far. The only downside is that you can barely move any apps to the SD formatted like this. But with the internal storage space of the Moto G it should be enough for now. I hope tough they fix it in the future. I'm wondering tough if it's not an Android issue. I wasn't lucky so far with internally formatted SD cards, on my previous phone if the phone crashed for whatever reason, anything that has changed on the SD since the last reboot would disappear. So I wonder if it's an global android issue.

I'm getting corruption errors with two brand new 32GB and 16GB Toshiba Exceria M302/EA microSD cards (http://www.toshiba-memory.com/cms/en/products/microsd-cards/exceria/exceria-pro-m302-ea.html).
Now I'm testing an old 16GB SanDisk Ultra and it seems to be working but I fear it won't last.
I have a G5 XT1676 with stock NPP25.137-15 and no updates available.

No corruption issues here. I bought a Sansdisk 128GB Ultra card. Ive been using the phone for a couple of months now. I have 80GB worth of music on it and I have photos saved to the card. I think the quality of your SD card will have a lot to do on seeing this issue. Good luck

Similar issue with 32 GiB Lexar SDHC, brazilian G(5)+
Greetings,
The same thing just happened to me: after a manual shutdown {1}: SD reported as corrupted, but reads fine on a Mac. The SDHC card is a 32 GiB Lexar and my G(5)+ is a stock factory unlocked brasilian version.
This did not happen in the prior manual reboots, since I got it in March.
{1} Launcher3 was throwing "not responding" warnings and Google Cards was very laggy, so I manually rebooted the phone after clearing Launcher3 cache and storage.
Cordially,
GemSev.

Update:
So far, all attempts at formatting in-phone stall, in both internal and external modes, at 20% and 30%, respectively.
Waiting for another SD card to arrive for further tests.

My Lexar card just died after a reboot it was working fine in my m8 before I got the moto g. When I plug in the card to my pc I can see all the files but they are write locked so the card is effectively dead.

Subscribed. I am also seeing the SD Card Corrupt on bootup. Wonder if it's bootup or restart/shutdown that messes it up? Tryinig to eject media, turning phone off and booting to see if it's happening on boot time or on restart/shutdown.
EDIT: Didn't have to go that far.... I press EJECT, then took out, inserted back in, CORRUPTED. Must be the EJECT or SD Prepare sequence? Or maybe an encryption issue (when re-inserted it has new keys/whatever encryption it uses?)
EDIT 2: I rebooted phone (power button until it rebooted) and SD Card shows CORRUPTED. It's either not updating the FAT table or must be the SD Prepare sequence corrupting it. I inserted the corrupted SD card on Windows and it showed "You need to format the disk in drive before you can use it." and no matter what format I use it gives me the message format not recognized on the phone.
I ejected the card via OS and checked on PC, CORRUPTED.
I HARD ejected the card and checked on PC, CORRUPTED.
I rebooted phone (power button until it rebooted) and ejected the card before boot and SD CARD is
CONFUSED!!!
It's like the card is good until it powers off, then it's no good.
CONFUSED!!!
Regret not getting the 64GB version now...if that's all I am going to have.. Moto needs to address this issue...

Fixed my SD card
This same thing happened to me.
I repaired my SD card by taking my SD card out of my phone and connecting it to my computer using a micro SD adapter.
When you click on the card's drive letter in Windows Explorer it will probably say 'This drive is corrupt and inaccessible'.
So I opened up the run box by pressing 'Windows Key + R', typed in 'cmd' then 'enter' to open the command prompt.
Then I typed the command 'chkdsk (drive letter of your card) /f'
for example: 'chkdsk D: /f'
Press enter and then chkdsk will run and should repair your card.
You should now make a backup of the files on your card just in case this happens again.

sd card is not even showing so how to format it
guys i have a samsung 16gb sd card it was lost and i found it after 2 days and now it is not even showing in any phone any pc.... i think its pin has tempered but if there is a way to fix it then tell me

The same happens to me, Moto G5 (NOT Plus). All cutom and stock ROMs have had this SD card being corrupted after a boot, came here for help but as I see, there's still no solution to this problem. Gosh, I'm starting to hate this device, buttons are not clicky anymore!
Last time i tried to make my SD card work, after watching a coupple of videos from my SD card, it couldn't read it anymore, I had to format it again, practicaly I can't use my device with SD cards. (Sandisk 16GiB Class 10)
