SD Card keeps becoming unavailable

Has anyone else come across the problem where the micro SD card seems to just stop being available to the phone? I'd say maybe once or so a day, anything that reads data from the SD card, such as the music app, stop working. If I try and play a song, it just hangs and does nothing.
I tried a search and somebody in the G1 forum had a similar problem but it didn't really contain any conclusions on what it is likely to be.
Anyone else had this issue? What is it most likely to be, the phone or card?
Thanks.

yeah I've had this occasionally with the camerea and seperately the 3d gallery software I installed.. have no idea why

Yea I've had that a couple of times actually. Just have to turn it off and on again and its ok, but its annoying.

Yeah, rebooting does sort it out, but it's starting to happen every day now, sometimes a couple times a day. If it's just a dodgy card or whatever I'd rather get T-Mobile to sort it sooner rather than later.

hmm a dodgy card.. included with the phone, that sucks

Backup your SD Card data and then try formatting it to see if that helps.

Cheers, will give that a go tomorrow. I might ring up T-Mob tomorrow anyway just to make them aware of the issue I'm having.
If I format it, will I be able to copy all the contents back on to it?

Yes, back it up to hard drive on your PC, then after you have formatted your SD card, copy back the contents from the hard drive to your Removable disk (SD card).

I've had this a few times Took the card out, reinserted and restarted the phone. Seemed to fix it, but it is annoying.

Sorry I can't remember when and how I know this.
But backup the card on your PC
Then format it in/with the phone and this should solve the problem I believe

I had killed one of my 16 GB card in Nexus one.
I found a problem that if i use Win 7 or Vista i must remove the device by using safely remove the USB device. Since now am doing this way i never had any problem.
Word of warning you could simply kill a card if you just remove a device.

My first thought was it has something to do with the USB connection. If you safely remove device in Windows - the phone 'prepares' the SD card.

I was having the same issue. I connected to the PC and mounted the SD card. I performed a disk check on the card and it found some errors which it then repaired. I then unmounted the card
I haven't had any issues since.

I formatted my card yesterday and haven't had any problems so far. thanks for the advice.

I ended up replacing the card. All of the previous advice didn't work for me or if it did it didn't last. I reckon there was a bit of a dodgy batch supplied by SanDisk.
~Since replacing I've had absolutely no problems whatsoever, it used to happen at least every 48hours. Very annoying when you try to take a photo and it tells you there's nowhere to save it.

I've been having problems too when taking pictures, which is really annoying!
And i'm not sure whether this is a related problem or not, but it could be...when trying to receive a file over bluetooth it sometimes says it doesn't have permission to receive the file or something along those lines, could this be the SD card playing up?
I'm on T Mobile, would they replace the SD card?

Not sure if it is the same reason, but I had all kinds of problems including the one you've described.
I'm on Orange, they told me that my SD card wasn't covered by Orange Care (the orange phone insurance). I said I didn't have Orange Care anyway and that surely it comes under the 12 months manufacturers warranty. They said pop it into the shop which is a bit of a drive and would cost me more than the value of a new card to get there.
At the time I wasn't certain it was the card as I didn't have a 2nd to try it with. Given my problem was very intermittent I decided the bother of going into the shop - it wasn't worth it for a £5 card. Now that I've bought a new one that works perfectly, I'm going to head into the shop with the old one next time I'm passing. The problem is I don't really need it replacing now! You could always lie and tell them you've tried your friends card at home for a couple of days and it worked perfectly?! No harm in trying.

Mhh - maybe I've had luck, but I use my over 1 year old 8gb cl6 card from magic/mt3g and never use that win function while unpluging anything (not while data transfer). So maybe depends on quality or manufacturer?

2-3 weeks since I've formatted my card and now I'm carefully unpluging my phone only when it's charging it hasn't happened ever since

I hate to say it, but it will happen again. Have card reader or other phone prepared, just in case your sd card stops working totally

2nd Micro SD Card Stopped Working - DHD

I woke up this morning on the sight of 'SD Card blank or has unsupported filesystem' message on my DHD. I restarted my phone, shut it down then restarted, but the message is still there. When I touch the message, it asks me whether I want to format it, I choose 'yes' but nothing happened. Then I tried to read the micro SD card on my laptop; again, it detects the card but fails to read / format. I tried to format it by both FAT and NTFC (just to check whether it's possible) but after clicking on 'Start,' nothing happens. Windows, then, returns a 'was not able to complete the format' message. (Xtreme 16gb Class 2 micro SD card - but the card itself doesn't have 'Xtreme' printed on it).
The same thing happened with my previous SD card a week earlier (the one that came with the phone, Samsung 8gb Class 2 micro SD card). However, the card wasn't even proceeding to 'format' and wasn't detected by my laptop at all.
What could the problem be? Could this be caused by a particular app that I have installed? I got my DHD on 25th of October, but this problem is very recent, and I had no problems before.
Help me out, please...

What software version is the DHD on?

Hi sengork,
The software number is: 1.72.405.3
I did a little research on the matter, and it seems as if this problem is since the latest OTA... but if that destroyed the first SD card, I don't know why the second one got damaged, too?

That's the thing. Most folk have not found out whether the OTA update (which you seem to have) causes only bundled Samsung SD cards to fail or whether it'd cause all cards to fail.
You might be the 1st example of the OTA causing failure on other SD cards. That is assuming that card didn't fail for some other non-OTA related reasons...
Sent from my Desire HD using XDA App

Yes sengork, I haven't found anyone else to have had 2 of their SD cards destroyed by the phone.
Common when both 'frying' incidents occurred;
i. happened late at night, when I was asleep (not using the phone for a long interval of time)
ii. had an unread SMS (had Go SMS installed)...

Did the Xtreme card happen to come with one of those 'lifetime warranties'? How much was it?
Sent from my Desire HD using XDA App

Yeah, it came with a 'lifetime warranty.' They have replaced the defective card and gave me a new one. It cost me around USD 30.
Well, today, my 3rd SD card has stopped working. I have no idea what the hell is going on...

It don't have to be broken....
Read this - I do not have a BB phone and to be honest - I have no clue what it means but might be helpfull... check this

For solutions on doing this with the DHD would be nice
Edit: can confirm in a BB - BlackBerry phone I was able to format the SD Card without problem and it is now accessable from the DHD again - issue fixed

[Q] Damaged SD Card?

A few minutes ago I went to get a new ringtone for my phone on zedge. It said "SD Card not inserted.", then exited. I knew I hadn't taken it out so i went to my music player and there was no music, went to gallery and it said no external memory and closed. I popped the back case off, removed and reinserted the sd card and my phone came up with a notification that said "Damaged SD Card" and suggests that i format it. Now, i've had this sd card since i got my original dinc2 last december, and never had any problems. I got my replacement phone late august and still haven't had any problems. i haven't dropped it or anything. So i put my sd card in an adapter and plugged it into my laptop and the laptop reads it fine. i can view/access all files on the sd card. i don't have another sd card to test it on though :/. so should i back up my sdcard and format it to see if it fixes it or is it the sd card slot on the phone.

Problem with SD card

Hi I had this phone for while and bought the sandisk Ultra 32GB class 10 sd card when I got this awesome phone. However lately my phone was acting strange. For past 4 days my phone will randomly unmount SD card and notify me that it got disconnected. When I turn on the screen then it will shortly mount the SD card and does not show these problem. Not only that these is happening consistently and keeping my phone awake and draining my battery as well. I don't have picture with me since I format my whole phone and SD card but this will happen at least 20 to 30 times in a hour.
I used to use Saurom Project Hybird 1.3.2 before and I format everything, from TWRP, and installed CleanRom ACE 4.5 but it is still happening with same problem.
Is there any way to fix these problem?

Same here

I have the same problem with a 32gb San disk, after searching all day the only conclusion I came up with is that sd card is going bad and needs to be replaced preferably for one that is not a SanDisk. I guess they are not compatible

Thanks. I was hoping that I didn't had to do that. Anyway do you have any other brand that is good?

I guess your best bet would be going with a Samsung sd card just to avoid having problems in the future.

I'm having the same problem it is not your SD card or at least I don't think so I read a different XD a thread for hey note 2 on a different carrier it was over 17 pages long of people having the exact same issue some say that the SanDisk 32 they are so then and that put in a piece of paper behind them will solve the problem but I'm not finding that word besides I find it funny it only does this when my phone is in sleep or when I'm in a phone call it is very annoying I currently am being told I have a blank SD card and sometimes later it may just work for no reason

If you're getting heavy Media Server battery usage with the unmounts, it's could be a bad media file on your SD card crashing the Media Server and causing the unmounts.
I deleted podcasts, videos, and mp3s off of my SD card and the error went away. A clean format of the card should also work.

I dont think that was my case. I format the sd card and keep it empty and mount the sd card and it was still having the problem. However when I change my sd card to my old one the error when away. I guess I got bad sd card.

[Q] Damaged SD Card

I apologize if this thread is made too often. I've been searching around for a fix, however I can't seem to find anything.
I'm running Cyanogenmod on my GS3. I've had an 8GB SD card that I pulled over from my old Evo 4G that has served me well for years, however I figured it is about time I moved on after spending the last few months deleting apps and videos to make space for more. I purchased a Sandisk 64 GB SDXC card and am attempting to use it with my phone, however I get the dreaded "Damaged SD Card - Try reformatting" error.
Of note, the 8 GB SD card still works perfectly fine, so I don't believe it is a problem with the SD card slot or anything. In fact, this is the first time I've touched the slot since purchasing the phone a year or two ago.
I've tried many things that people have recommended to others from searching around, however nothing seems to have worked.
I've tried reformatting it with three different programs as well as running chkdsk on cmd.
I've tried letting the reformatting process on the phone, which is prompted to me when pressing the notification for the Damaged SD Card", run for 15 minutes and it continues to run with the message "Unmounting SD Card" (which is odd since the card isn't mounted in the first place).
I can read the card perfectly fine on my laptop through the card reader, however it does prompt me to format the card every time I switch it over from the phone to the laptop, saying something along the lines of it not being in a language the laptop can read. After formatting, I can view the card as a drive.
Does anyone happen to have a fix for this? I would really like to start using my new card.

From a quick Google search on your problem it seams that SanDisk and Samsung galaxy's don't play nice with each other due to a flaw in SanDisk cards you may want to contact SanDisk about the issue.

Did you format the SD Card to FAT32 before using it ?

The only options I'm given to format it is exFAT and NTFS. I have only tried exFAT.
EDIT: I searched around and found that Windows only allows you to format to FAT32 with 32 GB or less. I downloaded a Fat32Formatter program that let me bypass that, formatted the card, and it works perfectly now! Thank you so much!

Your welcome . Glad you got it sorted out.
