Hi,
I've a Desire HD with the 8GB microSD card that came within. Randomly I got a message something like "Sd card unexpectedly unmounted and I can't access the card. The only way to have it back again is rebooting the telephone with the option Fast Boot disabled.
Any clue about what this should be?
Regards,
I had a similar issue, although I never got the warning, well, it never actually unmounted.
I would try and take a photo and it would drop to the homescreen. I figured I had to unmount and remount the SD card
I did a factory reset to fix it. Maybe the same can help you?

I have had the same from time to time and figured it was due to low quality of the SD-card.
So I actually just switched a few moments ago for another SD-card i got laying around. This is a class 6 card though and a bit better than the class 2 samsung card that comes with the phone. We'll see how this will turn out. Hopefully its a bad microsd card and not the phone.
This solved it. Havent had any problems with the card unmounting since i changed the card.
I had this problem, even start a new thread...
This is due to some corrupt file inside the sdcard or even a bad sector.
Try to do a "chkdsk /f /r" on the sdcard...
Hi,
I've checked the original SD Card with chkdsk as sugested and everything seems OK.
Since then I've changed the original card with a 16GB Class4 Kingston card and the problem does not happen again.
Let's see......
Regards,
If I did only "chkdsk /f" it also reported that the sdcard was alright... but I still had problems...
I had to use "chkdsk /f /r" to discover that I had a bad sector...
Now, for a few days I still hadn't any problems...
Oh, this didn't happened with the stock 8GB card... it was another SD card that I already had.
Replacing the stock card did help.
Hi Everyone
Any ideas why my Moto X Play would not even see my brand new MicroSD Card?
It's 128GB and so far I've tried it formatted as both EXFAT and FAT32 and no dice! It just doesn't even see the card.
Anyone have a guess at what gives?
**Edit**
So I've tried multiple sizes and brands of SD cards and none of them seem to be detected by android. Also tried resetting the device and no dice. Looks like my card reader may be borked.
** Edit 2**
I ended up having to return my device, as the card reader was pooched. The store simply did an over the counter exchange.
Can't see any reason why it wouldn't work. Maybe the card isn't mounted properly (in the wrong position) or as you said, you may have a faulty card reader on your phone.
I may be suffering the same issue. Have you been able to achieve anything regarding this?
I ended up having to return mine. The SD card reader was dead as I had suspected.
if you can format the sd card that means your phone see's the card and you can choose weather if you want to format as internal or external i like it internal but you have to get a faster card for sure and if you switching card from 16g to 32g....ect you have to forget the latter card then you can restore all your files. it worked for me.
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...
Hi everyone,
i have a G900F running on the current version of the ALEXNDR Rom, rooted, Knox 0x1, Android 6.0.1.
I have my SD card formatted as (mixed) adoptable storage (via adb), so I have 50% of space as SD card memory, 50% as adoptable storage.
And now for the problem: The SD card is repeatedly shown as "damaged". As soon as I put it into my PC, it'll work without any problems, but the SGS5 will work for quite a time with it, and then suddenly shows it as damaged and will not mount it unless you format it. It usually happens when a larger amount of data is written to the card.
So I thought that the card might really be damaged (was an old and small and slow one) and went vor a SanDisk Extreme 64GB card - same thing here. Then I read about some problems with Samsung devices and SanDisk cards (may the be true or not, I dont know) and swapped it for a Samsung 32 GB Pro SD card - same thing here.
Does anyone know why this is happening and how to stop it? Or will the adoptable storage just not work?
In addition: I could reproduce this when I was downloading Videos to the SD card from Amazon Prime Video for offline use. Seems that a) this is a large amount of data and b) split into thousands of small files. I dont know if its the number of files or the amount of data, but when I deleted the folder on my PC and put the card back into the phone, it suddenly worked perfectly again. Any ideas on this?
Hey there how are you?
I recently have had an issue with my samsung 128 sd card that was formated in a 50/50 mix from adb too.
As the sd card was formatted in exfat I posted an issue on the exfat home page. https://github.com/relan/exfat/issues/49 I was provided with advice on my mac on how to reformat it using the dd command. This was the only command that I came across which gave me an input output error indicating a hardware issue on the sd card.
I have since purchased a new sd card. I'm thinking of formatting it as either an ext4 format or f2fd format to see whether this makes an impact of its longevity.
Hope this helps.

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..

SD Card Corruption - Lenovo Community
https://forums.lenovo.com/t5/forums/v3_1/forumtopicpage/board-id/MotoG5thGen/page/1/thread-id/1525
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)
