SD card unmounting - Desire HD Q&A, Help & Troubleshooting

My 16GB SD card was randomly unmounting in my phone (Desire HD) I assumed it was a bad card as my PC would not detect it in a card reader. I got a new 16GB card today and it has started randomly unmounting in the phone, I get a warning message and the sd card vanishes.
This does not happen when i use an old 2GB card, the previous 16GB was running in the phone for at least 6 months.

I did I was originally on AOSP when I switched to Jellybean this started happening but the first thing I did was go back to AOSP. And it make s no difference, it is fine with a 2GB card but keeps losing my now 2nd 16GB card.

You sure the battery cover is on correctly. If not check the SD Card holder.
Last resort is to go fully stock and see what happens.
If the above fails, its a hardware issue

Thanks - going back to fully stock was my next plan at the weekend. Is there any form of pre-rooted stock ROM I can use, will going back to stock HTC ruin my bootloader and S-OFF and such things ?

Have you tried formatting the SD with the phone and not the computer? Also look for the rooted stock rom for your phone is your best bet, its out there in pd98 zip form. Good luck

The stock ROM isn't in PD98 format, its in a ROM, search for autorotation fixed in Jellybean and that the prerooted stock ROM
TheCorner approves..

I tried going back to stock and it still does the same thing, I noticed the SD card slot and SIM slot are on a daughterboard so I will try replacing it and seeing if it is a hardware issue.
Thank you for all your help.

I had a mounting issue after going from the stock 8GB card to a new 32GB one, all it needed was formatting and job done.. If you can format it in the phone do it, if not, put it in a card reader on the PC, it should open find it.

Thanks for replying but as i originally posted, I have had a 16GB card since probably last xmas, after going to Jellybean it started vanishing and that card is now dead, will not format in anything, PC card reader,laptop or phone. I got a new one and the phone has started ejecting it again. I assume the phone killed the original and this is not a card fault.
I have formatted the new card in PC,phone and my tablet and the phone is still losing it, it's fine on a PC. I am going to replace the SD card socket daughter board on the phone and hope it isn't a fault any worse than that !
Fingers crossed.

Download 4ext Recovery Updater from www.4ext.net and flash 4ext Touch Recovery if you haven't already. Then back up your SD card data, boot into recovery, go to 'wipe | format' and format SD card. Then go to 'tools' and run 'check partition alignment' and 'file system check'.
I used to have this problem real bad a long time ago with both an old 8GB card and a new 16GB card. I messed around a bit with all this and fixed it. I've rarely had the problem since. It happens once in a while, and a reboot fixes it. Not frequent anymore though. Also, format SD card in recovery always. I remember that this problem became very frequent for me when I used to format my SD card in PC with different cluster sizes. Don't know for sure if that was the reason or whether it was coincidence, but I suggest you format in recovery. Unless you use TWRP recovery, which just runs an 'rm -rf' command to delete all folders in SD card and doesn't actually format it. 4ext Touch Recovery is the best recovery for the DHD.

Thanks I will definitely give that a go today before ordering any parts.

I tried all the stuff with formatting and partitions and it made no difference to the new 16GB card, strangely my old 8GB card seems to work fine, so really not sure what would cause this to happen, none the wiser but the 8GB card will do fine for now.

[Q] CyanogenMod 7 is ruining my SD cards

Now I'm not moaning about CyanogenMod here, I'm just trying to understand how I can fix the issue.
Basically, I had CyanogenMod 7 RC2 on my Desire Z. That was it.
Eventually I saw through ROM Manager that the full release of 7 was out so I downloaded, took a backup, wiped everything and did a fresh install of the new ROM.
It installed fine, but none of my apps that needed root access were getting it.
So I booted into recovery, restored my backup, root was back.
I then installed 7.0 over my RC2. That worked fine, but again root was gone.
At this point, my phone started damaging SD cards.
It suddenly started saying that my 8GB card that came with the phone was damaged. I tried to fix it on the phone, but it just said 'Checking card' and then giving up.
Putting it in an old MP3 player, it is not detected at all.
Putting it in a card reader, the card is unreadable and when I try to format it Windows says the card is 'read only' (this is not due to the reader).
I put a functional 2gb card I had lying around into my Desire Z and it broke it in the exact same way.
My question to you guys is - what could be causing this and how do I fix it because I have a 16gb card coming and I'm obviously cautious of putting it in the phone.
Also, how would I go about flashing the new Cyanogenmod 7.02 ROM if my phone keeps breaking SD cards I put into it?
This error can be because when ever you install a CyanogenMod ROM over another, It leaves files your new ROM think is useful such as data that the new ROM doesn't support. It is damaging your SD Card because it keeps attempting to fix the error but is making it worst by trying to remove system files. Your best bet is to try another ROM and see if it does the same thing and report it to CyanogenMod Developer Team if it only does this to CyanogenMod ROMs otherwise it would be just a virus on your SD Card feeding off of personal data. If it is only CyanogenMod ROMs, we will adress this issue ASAP. Hope I helped
Thank you VS4, you are indeed helpful
I've since heard some people have managed to fix their SD cards by formatting them in ClockworkMod but I can't even mount it first in order to do this! Is my card truly dead?
Also, do you think the reason that CM7.0 had no root (even when it was a clean install) was due to me not 'fixing permissions'?
Thanks
Just a note to say that I've managed to fix it!
Despite being unable to 'mount sdcard' in clockworkmod, I found I was able to activate USB Storage and through this I was able to format the card (Windows 7 was previously saying that the same card was 'read only' in a multitude of card readers).
I hope this helps any poor chap with the same problem.
I had this exact same problem, munched 2 of my 8GB cards, and had a 16 on the way. I somehow fixed it before the 16 came and I've never had the issue since, glad to see an explanation of it.
Thanks, nofixio!
I had the same problem on my Samsung Fascinate with CM7. It ate my 16GB SD card to the point where the phone wouldn't recognize it, CWM wouldn't mount it, and it wouldn't show up on my computer in multiple SD readers.
I wasn't quite clear what you were suggesting when you said you were able to "activate USB Storage." I thought maybe you meant within CWM. That didn't work for me, but I was able to boot the phone up with the problem SD card in it and turn on USB storage as normal. Suddenly my computer could not only see the SD card, it could see all the files that were on it before it died! I backed everything up, formatted the card in Windows, and everything's good now. Thanks for the tip!

im running cm7 ... it wont read from computer. i tried several micro sd card readers. it just tells me it cant format. its just like what was mentioned before.
Weird, I've never had any problems with Cyanogen 7 roms. I've flashed one over another and had no issues at all, Mayb because I use SuperWipe before hand? Or maybe its a certain sd card issue???
Running Desire Z and Andromadus Beta 11 I had similar problem after I had applied remote wipe from Exchange (wanted to see if it works). Remote wipe worked: it destroyed contents of SD card and erased phone back to factory settings. After wipe mounting SD card failed and Andromadus seemed to be unable to format the card.
Solution: Booted phone to Clockwork recovery and applied advanced -> Partition SD Card.
Posted this on this thread since it came first when searching solution.

Go into Recovery (Clockwork), go to mounts and storage, then scroll down and it should say mount USB storage.

SD card not recognized by ROMs?

Strange problem with this desire, I can access the SD card from recovery with stuff like USB-MS and flashing from SD but with stock it says the SD card isn't recognized (the options in Settings are all grayed out). With a rom that has Apps2SD like InsertCoin where some of the main apps are installed to the card it just leaves me with a blank screen on boot with the background/top bar still there.
Pretty strange desire really, when I first looked at it the problem I mentioned above was happening (it was originally on InsertCoin, worked for around 4 months before this started) so I reflashed it to stock and then had it returned to me with the owner saying that their SD was broken.
If anyone knows how to fix this it would be much appreciated as I'm as stuck as a brick wall right now :/
Explain your problem in no more than 2 sentences that actually make sense and I may be able to help you out.
Add on information such as
ROM you are/were using
Can you boot
Does PC recognise phone
Hboot (S-ON/ S-OFF)
Have you tried with another SD ? Maybe it is the SD thats broken ?

Sorry, let me dumb it down a bit:
In Amon Ra recovery it sees the SD card fine and lets me use it over USB fine too but when I boot up into a ROM it doesn't seem to find it.
Using InsertCoin/stock ROM and neither recognize it, it boots up fine and the PC can see the phone too, but since it can't mount the SD card I can't use disk drive mode :/ It's using S-OFF hboot too.

The SD is fine, it works in recovery and in my own desire but I've tried another SD card to be sure and still nothing
hmm ok try to reformat the SD card using recovery and tell me if it works
I've had/got a similar problem. I believe it's a problem with the contacts between the sd card and the 'holder' for the sd card.
Try removing the back of your phone, removing the sd card, pushing down on the metal 'holder', replacing the sd card, and rebooting.
This works for me for anything between 1 minute and a couple of days before the problem starts again.
I have no idea why the card is still accessible in recovery. If the above had no effect then please ignore!
The only solution, and it's really not useful, is to remove the sd card. I've returned my phone for repair and nothing got replaced (my guess is because the sd card is still accessible on recovery)
EDIT: No longer convinced it's the contacts as whenever my phone 'freezes' if I reboot into recovery the sd card is always accessible.
Now think it's to do with the file system/structure on the sd card becoming corrupt.
If I format the sd card as one single fat32 and keep ALL apps on the phone then I have no problems.

P.S-i think i know the problem..i made an ext2 partition on the card for 1gb which it is not showing now even in the partition tool wizard..any ideas how to get it back,my ful card capacity???
solved it finally...it was a simple step...i had to make a partition in the sd card through cwm and give the swap size as 0..finally its working..thanks for ur support guys!!
No Luck For Me
I believe it may just be a hardware issue I am having. But maybe someone can point me out to something helpful.
I put the card in, it is not recognized, by either the phone, or by CWM
With the phone on, and in 'Settings' -> 'SD & Phone Storage', the card does not appear. I slowly pull the card out, and 'Mount SD' & 'Erase SD Card' both go from unavailable (greyed out), to full on available and White for a split second. After that nothing...
It does this with 3 different cards. an 8G Class 4, a 2G Class 10, and a 2G Class 4
I've contacted HTC about it, but who knows when they'll get back to me. Anyone here know of a solution?

It's as if the contacts inside the phone are screwed up. Like I said, when I pull the card out of the phone, while in the settings, it recognizes it on the way out for a split second.
I've been trying for the last half-hour to try to get it right to that point where it flashes the 'mount' to white... but I must just have goofy thumbs, because I can't quite get it...

[Q] SD card unexpectedly removed / Damaged SD card

Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.
Maybe its a bug in the rom?
Sent from my HTC One V using xda app-developers app
Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?
Sent from my One V using xda app-developers app
OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!
Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?

OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\
Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.

Suddenly Getting SD Card Unexpectedly Removed Error

Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know
I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I'll give that a go but why has it been working fine for over a month whilst exFAT if that is now the cause?

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.
Sent from my HTC One_M8 using XDA Premium 4 mobile app
Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.
I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..
when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
