[Q]HTC Desire HD SD Card Un-mounted Itself?[Q]

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.

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.

It can support 64gb Microsd cards from Sandisk. You have to insert it in your vibes and it will appear that you have a error n your sd all you have to do is format it and you have a working 64gb card in your phone. I'll pot picture later on for proof. I'm currently putting most of my music collection in my phone so it may take a while.

pocket now says original galaxy s handles it fine, but i'm gonna wait a few months till i get sgs 3. hopefully by then it will be cheaper too

[Q] microSD card died

I had a SanDisk Mobile Ultra MicroSDHC Class 6 32GB (formatted FAT32) in my Galaxy S3 with no issues for about a month. Then one day I was at work, unlocked my phone and got a "SD card has been unexpectedly removed" notification. After that the microSD card wasn't recognized in the phone, my laptop, nor my desktop PC.
Has anybody else had this issue?

question is, where did u buy the sd card it might of been a fake, their are multiple sdcards which look good and real but overall are fake due to the ability to operate in heat, so it might of overheated and crashed(died) its a big issue with fake sd cards out there, they usually go out or burnt due to not being able to take the heat of the phone. On normal operate the sd card should be able to take 40 to 45C which make it 90-100 Ferenheit, if its a real SD card it should be able to take more then this and reach upto 65+C or around there.
easy ways to spot a fake is if ure saving files on ure phone and it says u got a class 6 or class 10 sdxc card and its operating less then it should, it crashes on u when trying to open a file or it resets itself and tries to scan again for it. in many cases it will get too hot and burnt out, or it just stops operating out of the blue.

I bought the card from Adorama (a photography focused site) in April. SanDisk is letting me RMA the card (just got that approved last night). I just want to make sure it's not my phone causing the problem. Up until the "unexpectedly removed" error, I never had any issues with it crashing or having to scan for itself again (unlike the class 4 I was trying to test the card slot with right now).

If that's the case have u tried varies card readers or card ports to see if it could be the unit itself..... However if it does out that way, I believe scndizk does back this up with a lifetime warranty if ure sd card does stop operating and then should be able to replace it.

Even so the gs3 should be able to read ure 32gb flawlessly since it's supportive to sdhc, now it does also supports sdxc which is expected from higher performance sd cards to not be able to read or install correctly on the gs3 unless u format to extfat or fat32. Chances are u might have a bad sd card. By default their storage capacity is 32, after that, that's where u need to take does drastic measures. Try formatting it on ure computer, if it doesn't format then ure gs3 should read it, if it doesn't format u already know.

Had the same issue with my S3.
Turned out that the SD card was dying, this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the media scanning process.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card, and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:
https://play.google.com/store/apps/details?id=com.sdcardmonitor

Sd cards keep getting damaged?

I am now on my 3rd sd card. It seems my Galaxy s 3 keeps chewing them up. I get random sd card removed msgs and then it won't mount again.
Anyone had this happen? Can anyone recommend a reliable card that this won't happen to?
I've tried pny and SanDisk and both had this happen.

Are you certain its the card and not your phone? Get a card reader, and check to see if your PC/Mac can read it properly. If so, format and try again.
I've had cheap SD cards, and expensive. I have never had an issue.
Sounds more like your S3 is having issues. If the above proves the card is fine, try wiping your phone

I was having the same issues with my SD card but found out it was the ROM is was running that was causing the issues. I flashed Hellfire and have not had any issues since then. I would agree that it is not the SD card but its the phone.

Hrmmm.... I've been running this rom though with the same sd for a month or so now no issues.

I has a SanDisk micro 32 gig ultra or whatever, and it was working great until about a week ago.
I was switching between a couple different roms (paranoid android/kangdroid, frosty, ultimatum, black jelly, etc)
Then, it just died. I couldn't get it ready by any of the 5 devices in tried.
I got a hold of amazon, and and I have a replacement in the mail.
If anyone figure this out, let us know how to not only do this again, please lol

It's the way the SD card is formatted. I had this happen when I switched to AOKP and it kept telling me the memory card was damaged. It turns out I needed to format the card to fat32. Once I did that it worked perfectly.

So take it out and format it to fat32?

Any update on this? The same thing happened to me, running stock and unrooted. It looks like everything on my card is gone. Should I try another card or just go get a new phone?

Same problem here.... AOKP ROM and Jedi... my 8g card works but my 32g card will only accept certain files. I can't even create a folder in the external sd card.

Me too, with a 32Gb sandisk card. Card stopped working completely, and wasn't recognized by my phone or computer. I contacted sandisk via their web site support and a replacement is on its way. The approval process took a couple of days of emails back and forth, then they sent me a printable UPS label for RMA. They shipped the replacement out the day after receiving my return.

Same here, with a SanDisk Ultra 32GB card. It worked fine for a month, then just died. I've got a 16GB Amazon Basics that I'm using while waiting for the RMA on the SanDisk. The 16GB card had to be formatted xFAT on my Mac before the AT&T JB ROM (rooted via Mr. Robinson) would read it reliably, but it's been good since then.

Ext SD Card Not Recognized

Like the title says, picked up an SD card, doesn't show up under the Storage menu or when I connect to PC via USB. I've downloaded an app that lets me format the SD and it shows up there, but after formatting I still can't access or even see that the SD card in installed.
It's a GSKILL class 10 64gb SDXC

Hmmmm. Have you tried a different card to see if you get the same results? I'm using a Lexar 633x 64Gb card. No problems to report so far.

I am having the same problem with a dual sim D858 G3.
Have tried Sony, Samsung, Sandisk MicroSDXC cards of various capacities, none work.
Anyone have a solution ?

Hmmm, investigation with a torch and loupe revealed that one of the MicroSDXC reader pins were bent down.
Managed to lift it with a needle and now it works fine.
This was on a new phone, wonder if other people's problems had a similar cause ?

Format the SD Card in storage settings. It should format and be useable

Try couple things:
1. Try (may be borrow from a friend if you don't have one lying around) a different brand name card. Some generic brand cards (especially from eBay) are little flimsy and does not provide proper contacts. It happened to me on both HTC M8 and LG G3. Tried SanDisk card and all went well.
2. Try formatting the card using PC into Fat 32 format (you can always reverse this formatting to ex-fat) and see if this make any difference.
3. This one sounds very basic but under storage, sometime you have to manually click on "mount SD card".
Good luck!

Ok try this
1- but it in lapttop slot (card reader of laptop ) dont try another way .
2- use SDformatter 4 .
3- ok now put it in your device.
I hope it will work properly

I have this problem too. April 2017 and LG STILL haven't sorted it out. Impossible for so many owners to have faulty phones. Definitely a SOFTWARE issue ! Terrible customer service. I actually NEED to use an SD card in my work. .Never getting an LG phone again.

Have spoken to a repair shop and what they said is that this is a typical issue with the LG G3, another one (which I also see a lot) is spontaneous reboots, even when the phone is seemingly doing nothing. And these issues get only worse over time. The only way to solve them is to replace the mainboard, which probably isn't worth it. Looked at alibaba.com, they are around 30-40 USD. I have reflashed the stock firmware in my futile attempts to get both issues solved, but it is obviously a hardware issue.

Yeah stopped working too. I've noticed an issue with a pin in the MicroSD card slot. I imagine this is the issue. I'll open it up when I have time.

Take the card out, insert it in a PC and check it for errors. DiskGenius or MiniTool Partition Wizard can help you here. DiskGenius can also check for partition table errors.
Also make sure the card is formatted exFAT, not FAT32 or NTFS and that the cluster size is either 8K or 128K.
If that doesn't work back up your files, format as exFAT with 128K cluster size, then copy the files back. You may have to do this anyway if a partition table error is detected.
