So I noticed a very annoying single/double bootloop. When the phone starts, it boots, shows the lockscreen briefly, then goes back to the Samsung logo again and boots again, then finally goes to the lockscreen and functions normally. Sometimes, it loops twice before it finally finishes. 90% of the time, it does just one bootloop per reboot and then works perfectly fine.
Then I noticed it doesn't do this with my SD card removed. It's a 64GB Samsung Pro card formatted into exFAT with about 12,000 files on it.
Then I deleted most of the files from my 64GB card, bringing the number of files down to about 2,000, and it stopped doing the bootloop.
Then I put in a Samsung Pro 32GB FAT32-formatted card, put the same 12,000 files on it, and no bootloop whatsoever.
Anyone else experiencing this bootloop with an exFAT-formatted card? I have a strong hunch Samsung screwed something up in their exFAT implementation or something else that bombs when there are lot of files on the card.
Have you tried formatting the larger card in the phone and then loading it?

Yes, reformatted it several times, both in the phone and on a Windows 7 computer.
It's consistently sensitive to how many files are on it. 12,000 files = bootloop, 2,000 files = no bootloop.
And it only happens if the format is exFAT. It doesn't happen when it's FAT32.
I had this problem before I even fully loaded up my Samsung card. I reformatted and haven't had the problem since. I was having other minor issues at the time that got resolved. I am going back to sandisk next time I need a card.

Format your Sandisk to FAT32 & try it again.

Hi,
Seen various SD card problems posted here and other forums but no solutions.
A few nights ago I was transferring a large number of files to my Desire and noticed the transfer windows froze so I disconnected my phone. When I then tried to turn the screen on it wouldn't turn on (though the led kept blinking). I eventually had to restart the phone by removing the battery.
Upon restarting I got an error saying the SD card was corrupted and needed to be formatted. Tried restarting again etc but didn't work so clicked on 'format' in the pop-up but nothing happened even after several attempts. Then tried doing this through the settings menu but again didn't work.
Gave up. Wake up next morning and phone screen won't come on again. Took out battery again and still had memory card problem so connected to pc and formatted card on there. I think after this the card started working again but WITH ALL THE DATA STILL ON IT. No idea how!?
This morning after 4 days working fine I connect phone to pc to transfer music and don't get an option to mount USB so I unplugged and get a new SD card error: blank SD card. SD card blank or has unsupported file system. So tried everything I tried last time but this time I can't mount the card so I can't access it on a pc to format it.
Anyone had similar problems on here? Seems to have happened to quite a few on Android forums etc. Any suggestions? Have tried putting card in and out several times. Have tried SD mount widget. Getting pretty desperate here.

had exactly the same issue you had the second time, posted, found no fix.
Using a spare sd card I had in it's place, my phone registered it as blank again the next day! It was a reboot job though and it has been fine since..
Would like to get to the bottom of this before a blow a decent sized card
I have had many many bizzare and quite frankly random SD card errors with this phone. Nearly one everyday doing something. Most of them read the same SD card missing, needs formatting, is empty or corrupted notifications. The latest one occurred 5 mins back on reinstalling NewsRoom app -- suddenly left with a totally empty SD card when trying to save RSS to it. As in every case, an immediate reboot fixed the error so I can't offer any more help.
Whenever I've had the "needs formatting" error I removed the card for a few mins before replacing it back inand it worked fine thereafter.

I've just tried leaving the card out for a few minutes with the phone off and reinserting to no avail. Tried restarting lots of times
Going to try another SD card now. Most people on other forums had problems with their stock 4gb cards whereas mine is an 8GB card i got separately. I think it's the phone at fault not the cards.
**Update** The other SD card is working fine so far. But i'm now left with a screwed up 8gb card that's not recognised by any pc. Any suggestions of how to fix this?
If my 4gb card is screwed up by the phone too i'll let you all know
So I recently tried to put a 4.4 based rom on my cousins boost (d2vmu) s3. I tried cm11,cyanfox and avatar. All ran super smooth except for one issue. I get a "SD card unexpectedly removed" and "Preparing SD card" loop. I tried with two different SD cards (a class 4 PNY 32gb and a class 10 PNY 16gb). I formatted both cards multiple times using a combination of Windows, parted, and recovery and tried fat, fat32,NTFS and exfat and I get the same thing every time. I would normally blame the phone but wouldnt u know it, the stock ROM has no issues with either card. Occasionally I could get the card to mount on boot but most files did not appear when viewing the card with a file manager and eventually would go back to looping the error messages. Philz recovery also had no issues mounting and installing Roms from the card but occasionally hangs during a factory reset when it gets to /storage/sdcard1/.android_secure
I'm not sure what to try from here if anything. He's back on stock for the time being but I'd like to figure this out as its bugging me.
Thanks
I didn't see this particular fix anywhere else, but it seems to be happening with larger SD cards for many phones, so...
Running: L900 CM11 4.4.4 mid-august nightly w/ stock kernel.
Problem: My SanDisk 64GB SDXC SD card was mounting but showing no data and no absolute file size, with only the option available in tools being the delete all data function (I never tried using it though.)
Kitchen Sink: Tried rebooting, wiping both caches and flashing an older nightly. While a fresh card format seems like the obvious fix, transferring and formatting takes time on such a big card and requires a PC nearby.
The Fix: I booted the phone with the back cover off, and without the SD card inserted. After a full boot to my home screen, I then inserted the offending card and received a notice that it was loading. Saved data was now available with all functionality. After a reboot and battery pull, the card hasn't failed to load since.
I'd be interested in any insight to why this might have worked, it feels like a janky fix at best. A quick search tells you that big SD cards and CM/Android don't always play well.
Hey guys and girls!
This morning my phone turned off by itself (13% battery left) and needed somewhat longer than usual to reboot (in the meantime I plugged it back in to the charger). First thing I noticed was that my whole theme got reset as well as it started showing me introductional tips ("long press here to move your apps to the homescreen, ecc.). It also started to update apps in the Play Store even though I set it to manual ... so basically a LOT of things were reset.
The biggest problem I'm having now is though that all my files (pictures, videos, music) that are stored on an external micro SD card are corrupt. It's not possible anymore to open anything. I already removed the micro SD card and put it into an adapter to have a look at the files via the laptop. But nothing, even though the sizes of the files seem OK, I can't open them.
Does anyone have a clue as to what exactly happened here? Are those files lost (at least of some I have a backup) or is there anything I can do to "repair" them? Help is really appreciated, thanks!
PS: Things like the card unmounting and re-mounting never occurred. So I can't tell if the card was dying or if actually the phone ruined my files.
Did you happen to be using a SanDisk SD Card? I've had my 10 brick 2 of those until I switched to Samsung SD Cards about a year ago and haven't had issues since.
I never could manage to recover files from the damaged SD cards.
I have a Samsung SD card and had something similar.
I guess I was on Viper Rom and basically my phone restarted around 15-20% of battery. After a long wait for booting back again, all my settings were gone.
Files and others in the SD card was okay but basically until I formatted the card, I wasn't able to boot into the Download Mode to install a new rom...
I fixed the restart issue by installing the official HTC Rom.
Thanks for your replies.
It is indeed a SanDisk 16GB card. It seems though that the card is still working (no problems accessing it via phone or laptop), just the files appear to be broken. In the meantime I also tried apps like PC Inspector File Recovery, but to no success
I'm still on stock HTC Sense by the way, no root, nothing.
Anyone know though why that happened (resetting everything, etc.)?
Hit me with a PM I'll give you a SanDisk restore tool which works quite ok. there is a huge chance some files can be recovered, some will be damaged though. Don't push any new files on the card after you tried to restore the files
HTC 10-Corrupted microSD card
I know this is an older thread, but I was wondering if there is a solution. I have an HTC 10 which has an micro SD card in it, that is "married" to the phone. When connected to a computer, the computer recognizes the phone, and the microSD card, and begins to load the folders/files. Eventually this process stalls, and the phone/drive is no longer readable by the computer. To get the computer to recognize the phone/card again, I need to restart the phone, but the same thing happens again.
I have like 20gigs of data on the card, and cannot just put the card in a reader, because it's encrypted to the phone. Any possible solutions? It's frustrating to see the files/pictures for a minute or two, and then have them disappear. I have tried copying/pasting the files while they're visible, but this often triggers the computer to no longer recognize the phone/memory card. I've tried to un-encrypt the microSD card, but the phone can't recognize/access the microSD card long enough to complete that process.
Please help if you can.

Hello everyone.
My main issue for a few months has been the microSD card. Before I unlocked the bootloader, rooted and installed custom ROMs, my SD card worked fine, which was a SanDisk Ultra Class 10 32GB. After doing those things, my microSD card (or my phone) has been suffering a problem where it either corrupts or it disappears from the configurations of the phone, even after buying a SanDisk Ultra 64GB microSD card. I even unrooted, reinstalled the stock ROM and locked the bootloader but this keep happening.
This is incredibly frustating, because my main use for the card is Spotify, Netflix and Youtube Go! (I like to download everything on the highest quality possible) and every time it corrupts or dissapears I have to format the card and download everything once again. I even tried formatting it for internal storage but it dissapeared out of the blue other day just like it happens when it's setup as external storage.
Does anyone else have the same issue or know any fix to this?
It may be a hardware issue with the sd card reader

And only Motorola would be able to fix it?
A hardware specialist could, it's not just limited to Motorola workers.
I have similar problem/s
A. It takes a lot of time until card is ready
B. After it shows as ready, it can dissappear after a few min.
I u reinsert it, it takes more time, and sometimes fixes the issue.
The weird part. If it is ok, it will work like that until next reboot.
I really dislike this phone.

You don't need to format it
If it says sd card corrupted when you turn the phone on simply remove the sdcard (whilst the phone is still on) wait a few seconds then put it back in again
This works if formatted as external storage - not tried as internal as I don't see benefits in this

It says SD card corrupted while using the cell phone. Like, let's put this situation:
I had downloaded all my Spotify songs in the highest quality they allowed, listened to them while coming back from University on a Tuesday night. I put my G5 to charge during my sleep. When I wake up the next day to go to work, I cannot access any of the music, because suddenly my SD card disappeared from the cell phones (if I go check in the settings, it says 24,59 GB instead of 84,06 GB). After a few minutes, the SD card re-appears but says it's corrupted.
Since creating this thread, I haven't added anything to the SD card and I never got the issue again, so I'm pretty sure it's something with the way Spotify files work.

Have you tried connecting your sd card to the pc and check for the available space ? If it does then copy the data to your pc, format your sd card (ControlPanel>Administrative Tools>Computer Management>Disk manager).
Then re-insert the blank sd card into your phone and see if it shows up.
