Micro SD Volitility

Hey guys,
I have a 2gb SanDisk Transflash Micro SD and have been having some serious stablity issues with it. Ever since I first got it, it would lose a file or two randomly. Not a big deal, except that it was a picture of my kids once - that sucked.
But anyway, this morning the entire card contents (all 1.58gb) I had spent days compiling was inaccessable! The card still shows that it is full, but none of the files or folders is visible in either file explorer or in my card reader on my laptop. FYI: I had eight programs and 7 games installed on it as well as some music and movies. I don't want to reformat the card and lose all that, but I am afraid that this is my only option. I also don't want to keep using a card that is a timebomb!!!
Has anyone else with an Artemis (or any other unit) had this issue before and been able to rectify it? Any advice would be much appreciated! I'd love to hear that this is just a defective card and not a problem with the Artemis frying cards!!!

Same issue here
I have the same with my xda orbit, I have a 2GB microsd and once in a while suddenly I cannot access the data anymore, the folders and files are looking corrupt.
What helps for me is, to take out the memorycard, insert it again and make sure it is tight in the lock. Then, when you switch it on again, the files should all be accessible again.
I was thinking it might be a problem that the card is not tight enough in the lock so it would lose the contact, so what I did is that I used a small pice of plastic a little thicker than the lock of the sim-card to give higher pressure on the memorycard under the battery. Until now it works fine for me, but I do not know if it is a solution yet, I will have to wait some more days to see if it really works like that.

These problems do sound like a hardware issue. I doubt its the PDA or Windows and too many people have problem with too many different sized cards to be the card. It does sound like the card is suffering from an intermittant contact, I would try as above and make sure its a tight fit.

I,ve same issue. New HTCP3300, new SanDisk 2Gb micro. Installed set of application and then in one day found on the card folders with garbage names (even could not delete them). Reformat the card and install everything again. In couple days same probllem - programms installed on card don't work, and I can see strange folders on the card. Suddenly I found one not changed name on card with stored attachments of e-mails (more than 500) - long opening - then opened and after return to root I fount everything in place. Everything OK.
Does somebody has any idea what's happend?
How to fix it?

I've had the same problem in my Trinity with a Kingston memory card. Finally gave up and tried a different brand of memory card and everything seems to be ok now. Definitely sounds like these two issues are related. On the Trinity forum the general consensus is that is may be a firmware problem causing compatibility issues with some memory cards.

I had the same problem a few mins ago, Luckily after a reset of the phone all of my files were readable again so I would imagine rather than the card being corrupt, maybe some allocation table gets messed up.
fingers crossed that it doesn't happen again!

I had the same problem
Transend micro SD 1gb

Hi,
Does this affect the MDA Compact 3, or just the P3300?
Regards

Just happened for the 2nd time with my 2GB sandisk card. A soft reset brought all of the files back so I suppose it's annoying rather than a big problem for me. Nice if O2 / HTC got it fixed though!

and my sandisk microSD 2gb card after formatting in P3300 has turned to 1gb

i had the same probleme

Hi spangelsaregreat
Same problem with the T-Mobile MDA Compact III. Comes standard with a 1GB micro-SD card from T-Mobile (Sandisk).
The complete Benelux Plus map directory was corrupt. Other files/directories on SD looked ok.
Couldn't delete the corrupt files, had to format the SD card in the MDA Vario-III.
Greetings, Ben...

I've had my MicroSD only a few days so far but I have not encountered this problem yet.
I took the pre-emtive action of cutting a small square of the MicroSD packaging (that awful lethal theft-proof stuff) and placing it on top of the MicroSD-caddy before I clipped the sim-caddy into place.
My previous attempts to put it directly on top of the MicroSD, underneath the metal clasp that holds it down, met with failure as - contrary to what I've read elsewhere - the clasp is actually a caddy into which you slip the MicroSD before closing- just like the sim... forcing it down on top of the MicroSD probably wouldn't do it much good.
Anyway, so far so good- I can only recommend you grab some nasty plastic shell packaging and butcher it, worth a try... surely?

Corrupt Sandisk MicroSD
Hi all
I have been at the receiving end of this too. I have had this memory card for almost a year in my qtek 8500. I had everything from business data, cv, client logs, tom tom, and more importantly loads of photos and vids of my baby boy.
The card did go weird and prevented my o2 orbit from booting up properly, it just locked up. Took me a short while to figure out that it was the card and after i removed it it booted fine. I put the card back in and presto all working again.
Just 10 minutes ago I checked out my tomtom and ¨no maps¨!!! After examining the card on my mac, pc and card reader it's screwed. All data gone. just a few 0 bite files and daft characters. Nothing left at all. I am very gutted about this. All business data backed up etc so no worries there but the photos guys!!! I will never get those baby pics back! :-( very upset about it and it's definitely the pissing orbit as no other problems in any other handset for almost a year!!!! :-(
Any solutions to this as I cannot possibly trust this machine to store my important data anymore. I would like the ability to be able to sync my public folders in outlook then i could at least drop data into there while out on the go for backup. I'm not a keen believer in having to plug my pda in my laptop all the time to back it up as I have over the air email etc and i want to avoid all that pap!
STILL TRYING TO GET TO TERMS WITH THIS LOSS :-(

I am starting to think it may be microSD. I recently got an 'M3 Simply' game programmer for the Nintendo DS Lite, it uses microSD. I was using a 2gb because I feared feeding it to my HTC and a 1gb should be enough, then it suddenly became unreadable and unmountable. It would not format either.
CE

Has anyone tried a data recovery program like R-Studio. It can recover files off formatted hard drives and I have used it successfully on my SD card when my Uni messed it up, similar sounding problems.Might work.........

I did and it didnt work. my corrupt microsd was unmountable.

MicroSD
Hum, having the same here...
No solution yet?

I've just got the same problem with my O2 Orbit and a SanDisk 2GB MicroSD Transflash.
I've possessed the device for 1 month and it had been fine until a week ago. At first the problem was strange characters appeared in folder and file names. I reset the device and saw everythings back as normal.
But this afternoon Program Files and My Documents folders disappeared on the storage card. Soft resetting this time does not help. System still shows unchanged volume of used memory so these are definitely still there.
The former issue is also being discussed in this forum: http://forum.xda-developers.com/showthread.php?t=285511, but I suppose they are the same. Apparently this is a systematic fault so O2 and HTC must have been notified. Hopefully a solution should soon be found.

how to use 4 gb memory card in dopod 818pro

Hi,
I am using dopod 818pro. But whenever i use a 4gb(mainly kingstone SD memory card) memory card, it shows, "no memory card installed". But i can use 2gb memory card (any brand).
My config is as follows-
windows mobile 6.1 professional
processor- OMAP850-195MHz
memory- 50.02 mb
ROM version- 7.0.0.7 WWE
ROM DATE- 7/5/8
RADIO VERSION- 02.19.21
RAM size-64mb
So please help me to use 4 GB memory card.

SDHC
The HTC prophet doesn't support SDHC cards (over 2 Gig)!

i'm using non sdhc 4gb card from transcend. make sure your card is not sdhc...

oh yes, but you still need a driver
hey man, if you have a normal SD card with 4GB, it still will not just work ,you needed a driver of some sort, sorry, I had it, but changed my computer some months ago. Maybe someone else has it?

do you?? i just put the card in & my prophet recongnised it.

SD
I used to have MMC and I thought the disable power management would resolve my problem of getting my files disappearing from the card if the path 2 or more folders deep, but when I changed the card to a normal SD (2GB), I had the same problems happening sometimes (but not as frequently as before), but I'm getting another (harder) problem now. I'm saying harder because this seems to be very hard to track because it happens when it wants!!
sometimes the card works for several days without any issue, but sometimes I get a blank card. even though when I look at the status I see the used space and the free space, but when I open it with resco or file explorer it's just blank.
and I even got a worse problem (fortunately it happened only one time yet). since I set the ie and opera cash to the card, these programs created their temp folder on the card again, but everything else was totally erased! I used a recovery software to get my data back!!
as I said, it happened once, but the usual problem is I just see nothing on the card until I shut down, and boot my prophet again. and sometimes it doesn't work until I do this several times.
I think I've looked everywhere to find a solution for my problem, but I didn't find any real solution for it. I've tried several roms, several cards, always getting the same problem. I don't think it's a hardware issue because of its nature. I mean how could it be a hardware issue if the data disappears without even touching my phone? if there is a hardware issue I don't think the card would be recognized at all! or (at least) it won't be recognized after I move it (causing the weak or loose contacts - if any - to disconnect) however, I don't think it's true, because the contacts are clean and tight, and like all HTC devices, the SD slot is high quality.
if anyone can offer a real solution to my problem, then I'll say he/she is the one who enabled me get the full of my HTC Prophet!
So thank you in advance. whoever you are!

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

SD Card Unexpectedly Removed

Hi guys,
I've seen this issue addressed on forums for other devices but didn't see a thread for it here.
Anyone else experienced this before? Constalty getting an error message for "SD Card Unexpectedly Removed". It's a class 4 32GB SD Card, it's installed securely in my GS3 in an Otterbox case, running on my rooted stock JB device.
I can usually access the SD card data after a few minutes but then often when I wake my device still get the same message.
Do I need to format the card??

I had an S3 that initially reported this error. It eventually started ruining sdcards.
AT&T eventually ended up giving me a new one.

Anyone have any further input on this? Earlier tonight, mine gave me the same warning. (Also installed securely inside an Otterbox case, running stock/ non rooted). I just popped the card into my laptop and my computer doesn't see it. It really looks like the card's ruined and everything on it is gone. To say that's not cool is an understatement...

Mine started saying it's ejected last night, also in a case, randomly saying it's back. Still works fine in a pc. Assuming it's the slot and not the rom...poop. guess I need to Odin back to stock and try to get a replacement.

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

It might be a bad sd card, i used to get that error on another phone when using a certain sd card but when i tried another one it worked fine. Maybe try another card see if you get the error.

Apparently sgs3 have problems with SD cards anyway

I had this happen to my friends phone the other day. Best thing to do if you can't access the information may be to run chkdsk /r which will check for bad sectors and recover any readable information. Move tour info off the card and try to reformat to fat32

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.
