[Q]HTC Desire HD SD Card Un-mounted Itself?[Q] - Desire HD Q&A, Help & Troubleshooting

Hi XDA, seriously problem here that I really, really need to fix.
My father left his phone at home for the FIRST time ever today, his HTC Desire HD was one of the first in the UK, he go it the first day it came out. Today he forgot to take his phone to work, so I put it on charge for him and left for school. He came home halfway through the day to find a warning in the notification bar alerting him that the SD Card had been un-mounted. On seeing this he immidiatley blamed me, as any father would do to a son that enjoys messing around with electronics, however after taking a closer look I noticed that the phone will accept any card except the one that was in it when it unmounted itself at some point within the day.
The card that broke, is the origional Samsung 8GB that came with it (on Orange anyway ~ unbranded as first in UK FTW) when the Samsung Card is inserted all the stats about the card show as Unavailable, and the phone doesn't even recognise a card as being inserted, the same happens when the SD Card is plugged into my computer running Ubuntu & Windows. The card is not recognised at all, infact Ubuntu thought I inserted an empty SD Reader, and thats from Ubuntu! My dad has so much saved to that SD Card, like literally 5 months of holidays and things, I know he should have made back-up's, but is there anyway we could get this back. Thanks.

Hey i had a simmaler problem but i fixed it with my 16gb micro sdcard by takeing it out of my phone and pluging it into my lapyop and move all the files off the sdcard and onto the desktop and then move then back and then put it back into the phone and turn it on and see if it worked
If it didnt please responed and tell me the exact message it says

Hey Man,
I would do this, but my computer doesn't detect the MicroSD even if its in a SD Reader and plugged into my PC?

I had a similar problem... after i got my DHD, I bought a 16gb card for storage. I used this for about 4 months then I started to get the dismount messages every now and then, particularly when the card was being used a lot (playing music from it especially). Then a few days later it would do it after every boot.
My PC can see the files on the card, but trying to copy them off throws an error. I can't format the card either. I have since bought a new one and that is working fine, so it may have just been a faulty card.

It is HTC's fault, bug in the rom causes that. Your father should get an OTA update any time soon that will prevent it from happening again. You can format the SD using a PC and a card reader, it might just revive the card.

If you want to retreive data on the SD do not format or delete the partition.
Try to use a "data rcovery" tool first.
But if it's not recognise at all (like a piece of plastic and not as a non formated sd) all data maybe lost.
Usually OS corrupt the SD, it doesn't destroy it. If it's dead it not your fault or the OS fault. It's just no luck (try to explain this to dad ).

And beside I think its an San disc not an samsung, like I have, and try read it with partition manager. If not you can get a new one. And never buy Kingston cards, I had 5 of them and all died in few weeks.

Kingston makes the best and fastest cards, you have just abused them or something like that..

I do not think so, all Kingston was a waste of money for me, but my sandisc m2 micro sd are working fine for 6 years with no problem at all.

Well, both Kingston and SanDisk have worked well for me, and the price is usually almost the same. The difference is that Kingston gives absolutely awesome warranty, and the cards are fast has h*ll. My Class4 Kingston reads 21 megs per second, and writes 12 megs per second.

IMO the Kingston of England is not the same one in Finland, call me stupid but I lived in both countries and bought many Kingston memory sticks/SD cards from both

Loads of bootleg Kingston cards in England and I never noticed any kind of warranty on them while it was the most tempting thing on the ones I used to buy from Finland

Thanks for the information, i've sent an E-Mail to HTC complaining about it. Hopefully they will see the light, and send a new SD-Card as it was shipped with the phone from HTC.

[Q] SD card unexpectedly removed

Using the pre-installed stock Samsung Class 2 micro SDHC 8gb
Constantly getting this error from the DHD:
"SD card unexpectedly removed"
Symptoms:
1) Usually happens after installing / removing apps.
2) Tends to re-boot by itself after "hang" after about 10 seconds
Note the following items:
1) USB Debugging = ON
2) SIM card is fully inserted
3) SDHC card is fully inserted
4) Using stock ROM
5) PC Error Checking (bad sector) = No error
6) Have tried to format the SDHC. Result = same error
Any ideas on how to troubleshoot tis ?
Is the pre-installed SDHC card at fault ?
Thanks
Another thing you can try is to check with another card (New or Old)
If it still does it....then there shud be some problem with the card holder unit or something...get it replaced mate
Had the same issue. Think your SD card is broken. Mine was. Couldn't even get it to work on a pc. Tried a new SD card and the problem was gone. Just got out of the Vodafone store. They replaced the SD card under warranty.

I've got EXACTLY the same problem. It's bloody crazy!
I read that the phone may not be able to cope, as it's only a class 2 card - but I don't think that is correct, is it?
I've contacted HTC, and they just told me to take it back to the store and ask them to check it out. I'll probably do that in a week or so.
it just happened to me!! randomly. everything was fine and then suddenly it just failed on me. any clue why?

Bundled Samsung SD cards with the latest OTA update are known to fail, search for more info in other threads here to see if you'd qualify for a warranty replacement.

Been happening to me on the stock Samsung class 2 8gb... anyone encountered any problems changing to a class 4 card?
Sent from my Desire HD using XDA App
when I woke up this morning I couldn't access any of the programs on my sd card (SanDisk 16GB Class 2 SDHC), when I rebooted my desire HD the same thing happened. I tried manually mounting it, rebooting like ten times, inserting, ejecting the card etc, nothing would work.
Can't be the phone just smashed a 16GB card over night :/
YES....!! Gggrrrrr! it just happened to me last night. I rebooted my phone after installing some different Apps throughout the day (as is usual in my Android daily life). then after the phone rebooted about 30-45 seconds later i saw the "SD Card unexpectedly removed", thats strange i thought. Couldn't get past that after about another 4 reboots i removed the SD Card and tried it in a card reader on my PC. similar thing, I could ready the file structure on the WIN PC but then about 30 seconds later the drive disappeared and was no longer available. I then re formatted the card (started the process withing the first 30 seconds) and thought that would fix it. Now neither my WIN PC or Desire can read the card. also tried in Lynx Puppy environment but no go.
I think my 16GB Class 2 card is TOASTED. Was it because it used an Ext4 Partition on the card for the past 7 weeks? I heard some people in the site saying that Ext4 can damage your SD Card...?
Had the same problem - lost all my unbacked-up data. Quite disappointing. Bought a new micro SDHC and hasn't had a problem since.
So it's the SD-Card then?
It's happening to me most of the time and it's really anoying!
Yep time to buy a new one.if your luck and still able to access your old card then get it backed up quick.......before it goes tits up.
Sent with Desire.
Just visited the HTC customer center last week to check on this issue. Seems like its got to do with a bad batch of cards.
They replaced an identical Samsung microsd class 2 8gb card to let me use for a couple of days. Told me that If I was to still encounter the same problem, it could be problems with the card reader chasis, and I'd have to leave the phone with them for a couple of days.
I'm happy to report that I have not had 1 single "SD card removed unexpectedly" since I got the new replacement card.
I highly suggest for people facing the same problem to get their cards replaced by the seller or HTC.

I just have the same problem like yours.
I tried many way and methods, It just can't working fine!!
so I buying another sdhc as sandisk 8G class 4
now I have no problem for two months so far.
I am reasonably to Suspected...
that the problem happends cuz this garbage samsung SDHC!!
Change it now! you'll feel like:[what a wonderful world~]
The "telus" version comes with an 8gig class 4 card but upgraded to a 16gig class 10. No problems either way.
Guess Canada nipped it in the bud
I was going fine with the stock 8Gb card and then I replaced it with a class 10 16Gb card and after about a week it started randomly ejecting. The card worked fine in other devices and can always be read in Windows but I guess it's only time - I have had another card go in the past and it's a real downer.
I'm not convinced it's the card. I've tried uninstalling any suspect apps but it hasn't made much difference.
Formatting the card and replacing all the files kind of works but I have still had one random 'eject' in the last 48hrs since I last formatted.
Actually the problem seems to have started when I re-flashed my current rom - Android_Revolution_HD-4G_4.0_beta4
Wish we could find out what is going on here.
Having the exact sample problem, but with a 16g card that I bought several month ago. I have another 16g card, will swap and see if the problem go.
I had this problem as well
So I formatted the SD Card and had the problem since...
however sometimes, it cant seem to recognise some pictures in the card, so i use SD rescanning app...
Heard someone saying this was caused by an OTA, well I had a warning around 2 days before the SD-Card Un-Mounted saying that the Card was in Read-Me format... anyway 2 days later my SD-Card became un-mounted and then became comepletely useless. I was unable to mount it or anything, going to get my dad to ring up HTC, as we rung my carrier and they said the problem 'had never been reported' which is bull**** as theres enough people here with the problem...

External SD card disappeared...

So I woke up this morning, phone says SD card unplugged, please insert new...knowing that I obviously did not remove my external sd card I then proceed to check
Settings, Storage --> (nothing shows up)
Boot into recovery --> can't mount external SD card
plug it into PC --> nothing shows up
So now the question is, do I have a bad/dead micro SD card or else?
I am on CM10 which is updated nightly, that might have something to do with the SD card, I dont know.
Edit-- missed where you said you already tried directly from computer.
Might just be a dead card.
Unless it is just not being assigned a drive letter on the pc, the card is toast. If you are using windows you can got to the disk management snap in from the administrative tools and see if it is listed at all, if it doesn't show there it is fubar. Easiest way to get there is right click computer, manage, disk management. For linux or mac im sure there is a similar tool but i couldn't tell how to get there or use it.
Which recovery do you have? Same thing happened to me on 6.0.1.4 Touch. Computer still saw the card, so i pulled everything off the card, reformatted with the computer, then changed recovery. Phone saw it after that and no more problems since.

Thats just the nature of flash memory, eventually it does go bad and unlike mechanical drives which often give plenty of warning of impending failure flash rarely does. Granted 2 months is obviously not acceptable it could be just a freak thing or maybe just an inferior brand. It is also highly susceptible to static discharge, especially in a SD card type format where the pins are exposed. Although possible, i doubt a static shock happened inside the phone but it could have possibly been damaged and just took a while to completely fail.
I used this to format my 64gig chip

Get a new card...i would also check on any warranty offered by the manufacturer, that goes for OP too. Depending on the brand there may be a 1 year or even lifetime warranty, some of the lesser brands might not have a warranty at all. Although i haven't followed my own advice in this category as the last 2 16 GB micro SD's i've purchased have been fairly cheap class 10's, you more often than not get what you pay for. I would also recommend going for the class 10 cards, not only do they have the fastest transfer speeds (and maybe because of this) they seem to be more reliable then their slower cousins.

Although i've never had one of their SD's, Kingston is one of the top tier memory companies and carry lifetime warranties on most (if not all) of their products. At the very least i would expect a year.

In my experience SanDisk is considered a cheapo brand but they have been around long enough to have overcome that reputation. I would imagine they also have a warranty program although i can't speak from personal experience, definitely worth checking into.

Any possibilities that my S3 killed it?

I don't think SanDisk is a cheapo brand since they have been making great cards for a long time. They have a great warranty program. They will replace anything within a year for sure. I had one that you couldn't read the serial number on so they still replaced it.
SanDisk has a problem by being the most well known microsd, they are faked by chinese companies all the time and those fakes look just like the real ones. Therefore, you buy a fake, paying real prices, that looks real, and you blame SanDisk. I think that was what happened in my experience with a dead card, and they still replaced it.

You can't just format it from "My Computer". You will have to go into device manager and find it, then format it that way. Otherwise it will not work.

UPDATE (see post#30):SanDisk Ultra 32GB kiss of death? (

For the past 4-5 months, I've been seeing quite a few posts regarding issues with the SanDisk Ultra 32 GB microSDHC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-032G-U46. I bought one back in November 2012... been running it hard for 6 months without incident.. so figured I was one of the lucky SanDisk recipients.... until today! Starting today, every time I wake the phone get the "sdcard mount" message. So loaded "SD Card Monitor" from the Market (screenshot attached) and found that during deep-sleep, it unmounts/mounts/removed/bad-removal/ejects constantly (example: phone slept from 10:04am to 10:22am)...but during wake state, no issues. So I suspect I'm about to experience the SanDisk 32GB Ultra kiss of death any day now. Backed up ExtSD to computer, but now the search for a proper extSD replacement. Any recommendations? Leaning towards Samsung 32GB or 64GB...
UPDATE: SEE POST # 30
Yea I just bought mine about a month and a half go. One month in of using it, my card corrupted and I ended up having to reset it. Lost everything! Lucky I put anything of importance on my cloud before it finally died on me. :banghead:

I got my phone 2nd hand, and that's my next step to order a new sdcard/sim card module and try to replace it. Data works fine and never cuts out, phone calls last maybe 30 seconds, and it's killed 2sdcards already. ..

FAT32... not a single problem for 5 months until today... and I r/w the crap out of my extsd cards daily... we'll see what happens.. still works, just getting these warning messages.
Really like that Samsung SD card idea.
Back to Amazon. ...g
I purchased one of these from Amazon last week. Works like a charm, albeit only when formatted as FAT32.
It is roughly twice as fast doing read/writes than my previous Samsung 32GB card.

My Sandisk stoped working also, so I bought the samsung 32gb and it's starting to do the same thing again. I just think there is something wrong with samsung phones in general.
I haven't had any issues with my sd card or phone. But a buddy of mine has burned up 3 pny cards and one sandisk. Although it's an s3. Sounds like a phone issue. I told him to call a warranty claim.

[Q] Bad 32gb micro? ...or did I F up?

Im not a stranger to rooting (thanks due to all the awesome devs here!) But sadly a ran low on storage. Bought a 32gb Sandisk class 10 ($24...Why pass on that?!) I copied current sd to computer, then transferred to new sd card. Well, phone was incredibly laggy. Ended up freezing. Pulled battery, rebooted.... froze on samsung screen (waited almost 10 mins) Pulled battery again. Attempted to reflash current rom, but upon reboot it sent me back to recovery with message of no OS. Not one of my roms would succeed. Back to old sd card.
Now i must ask, did i miss something here? Or is it a defective card? Im a sucker for punishment. I formatted card, only putting rom files on to use. Still failed on me.
Returned to original sd card, reflashed rom. Back to normal!!
There is a known issue with SanDisk SD Cards, and the Samsung Galaxy S3. You can find more info HERE. I believe the the issue has since been resolved. You can try to format the SD Card with SD Formatter. It may save the SD Card. But either way you can follow the link I gave you. There is another link there to the SanDisk site. They should replace your card. Or you can take it to your local retailer with a copy of the link page. They should take care of the issue.

I would try contacting SanDisk directly. They may replace it.

I got mine as a gift and mine went out recently...emailed sandisk a few times back and forth (they ask where it is from, never gave them a receipt or anything) and they replaced it for free...just got it today!

That's seems to be a matter of opinion. I still have a SanDisk Ultra SDHC 32GB Class 10 micro SD Card. I had to exchange it once. But after I received the new SD Card, I've had ZERO issues with it.

Same here. Since replacement haven't had a single issue. When I contacted Sandisk never required reciept.

HTC 10 damaged micro SD card

HTC 10 damaged my micro SD card. Did happen to anyone else?
I listened music form my phone on my way to work in the morning and then, on way back home firstly music didn't play, so I found that card is not recognized by the system even after restart. I have checked it later on two computers with 2 different adapters and no appliance can recognize the card. Branded 64 GB Lexar fast card. HTC wasn't restarted or so, wasn't even hot I kept in whole day in the pocket. I'm not sure what to do, I mean don't want to lose another memory card which I probably buy.
And maybe, by any chance, someone have any idea how to check memory card whether is completely dead?

Did it ever occur to you the card could have had a hardware failure?

It's more likely a short life span micro sd card, and this kind of suck always happen once a while.
Don't blame your phone unless other one or two micro sd cards also die in the first two weeks.
Hi, The reason I'm asking is to avoid the risk in the future. If it happens to anybody else I will rather buy some cheaper card.
That memory card was bought for GoPro so I use it for many other apliances without any problem and suddenly it broke with HTC 10. At least I noted it here for statistics.

...and if it had broken in one of your "many other appliances" it wouldn't have been broken by your HTC 10.
Cards fail. Cheap cards fail often.
Lesson, buy more than one card and don't recycle them from device to deice.
Another lesson, don't ever buy cheap cards.

lexar isn't usually horrible, but yeah sd cards fail. On the notes of sd cards dying my t3i must have killed my sandisk ultra 2, it couldn't have been the card that died.

The HTC 10 does appear to be finicky with microSD cards. My 128GB Sandisk that worked totally fine on a Galaxy S5 kept giving me problems on the HTC 10. I wonder if the phone is stressing the cards too much somehow (for instance if it is scanning the card too often for media files and you happen to have tons of media content on the card like in my case).
Thank guys for the reply,
I never broke before any memory card and that one was not cheap. Happily I can buy now double capacity and double speed for half of the price which I spend for the last one. I'm planning to buy Lexar 128GB. That card did work perfectly but only few days.
I'm having issues with my card as well. I purchased the SanDisk Ultra 200GB Micro SD from amazon. I put it straight into the phone and ran diagnostics on it to confirm it was a true SanDisk card and its read/write speeds which were in line with manufacturer's specs (88 read/ 14 write). Within the day it was having issues pulling images off the card. All the images saved directly to the card had a grey area or "box" over some portion of the photo that would correct after a few seconds leaving the full picture to view. The images could be sent with no problem but eventually they seemed to become corrupted. I figured it was the slow write speed causing the issue so I replaced it with a new Samsung ProPlus 128GB card (95 read/ 90 write) and the issue still persists. Not sure if anyone else is seeing anything similar.
if your looking for a new one, this one is great. very fast speeds 90mb write 95mb read. bit on the spendy side so hopefuly it was just the card failing and not the HTC 10 eating them
I haven't had any issues with 1000s of files on mine so far, crossing fingers
Same here, Kingston 128 GB micro SD worked fine on my s7 edge. Inserted the same card in my HTC 10 and it was readable for the first hour, after that the card was not recognised by the device. The card wasn't even recognised by my Mac and PC. I'm glad I had my photos backed up on google photos.
My 64gb kingston kicked the bucket in my HTC 10. Last weekend I woke my phone up and it said sd card unexpectedly removed. Card was not readable in any other device.
Got a Sandisk as a replacement as never had an issue with their cards in the past. The kingston only lasted 4 weeks, but I'm putting it down to just a faulty card.
If the sandisk dies too, then I'll be a bit concerned it could be the phone...
Im Using Lexar Pro SDCARD 128gb and havent had issues using it. The card was also formatted as adaptive.

So, there is two of us. There is one only connection - 64gb.
Where is Sherlock?

You're made me worry. I use SanDisk 200 Gb, it's kinda expensive one.
Worry for what?
I don't have any issues with my HTC10, but I broke a 64gb Sandsik in my Sony X10i, phone just got hot. Shut down, Card didn't work anymore. And another one SanDisk 128gb was in my Sony Z2 when I replaced the back plate somehow the MicroSD got broken.
The 64gb Card had a Lifetime Warranty and the 128gb a 10 year. Not sure how long my 200gb card is now. Think they reduced it to 3years or 5.
But yeah, went to their Homepage, registered the cards. Requested replacement, they sent someone here to pick them up, 5-9days later I got the new Cards via Mail
So yeah, always back Up your important stuff somewhere else and who cares if they fail. It's annoying Yes, but **** happens.
SD cards can fail in ANY device. I wouldn't go as far as saying it failed because of the device. Quality of the cards is what really dictates how soon failing can occur. A knockoff SanDisk failed in a few months while the real one has lasted years for me. I highly recommend SanDisk and Samsung SD cards because I have had no issues with their original products.
EBay and some Amazon sellers have tendencies to sell fake cards so beware.

I woke up this morning and my HTC 10 says that the micro card couldn't be recognized. Crap. Did a search and found this thread. The card is a Lexar 64gb card. I went to Walmart this afternoon and got a Samsung 128gb card. Hoping this card will last my long tern stress test. Ha!

+1
been using this without any problem 128gb and prior to this i tried samsung evo + 128 and that worked fine....
but as the OP stated it is true that many users using diferent sd cards has been facing issues with htc 10.....
some has issues on some firmware, some on custom kernels, some on different formats so its wise to say that there is something beyond a faulty sd card itself.
in all the custom rom threads you could see sd card issues highlighted at one point or other by mutliple users including devs
I have the same issue, and now i remember this is the second one in my htc 10, first one a pny 128gb worked well for more than one year in my previos s5 and after a month in my htc it failed, i blame the sd card that day and decide to buy an 128gb lexar and today after 5 months it failed, or i have a very bad luck now or my htc is damaging my sd cards.
