[Q] My external memory card's been erasing itself - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi, I got my Galaxy S a 16GB memory card 2 weeks ago then I started to move my apps into the memory card. It was okay until one day when i restarted my galaxy S and suddenly it says "damaged SD card" and asked me to format it. However after a while the "damaged SD card" warning was not there again and i thought that my memory card recovered itself. but when i flipped through my external sd files it's empty.
After that I just reinstalled all my apps and tried to place them back into the memory card again. It was working fine for a few days. however i just realized today the content inside the memory card went missing again. No 'damaged SD card" warning at all..Just disappear.
HELP!! was it the memory card problem or problem on my SGS?
It was a Sandisk external memory card.

Sandisk web site have a test tool .

you probably bought a fake one or something off ebay.

I did not buy it at ebay. It's from a computer shop and on the box it says 5 yrs warranty.
how do i differentiate between a fake and real ones? tried searching for it but only told me about normal SDHC memory cards.

It may be defect on your micro sd card so if you have other phone let's try it.

i tried on an SE phone before when the first time it said it was damaged. when the photn read the memory card it was empty. after tht i tried placing it back to my sgs and the memory inside was lost but it can still be detected.
now the memory card cannot be detected by my sgs!

i tried on an SE phone before when the first time it said it was damaged
Thats your answer DAMAGED .

damaged sd card ugggg

I tried to copy a bunch of files to my sd card and it crashed during it and says that the sd card is damaged. it says it needs to be formated. but when i try to do it in hero it does nothing. How can i format it. when i try to phone just sits there and then locks up and shuts off. have to pull battery and restart.
no one has a answer. there has to be a way. i need my sd card. i dont want to have to buy a new one when i have 2 that should work.
I had a similar issue with a 1 year old 16GB card last week. Card was destroyed and I couldn't get anything off of it. The MBR was damaged and wouldn't be re-written. Had to go get a new card :-/
Tried this one:

I used my mac and disk utility to format, partition and a bunch of stuff... then i formated using my hero. it worked after that

SD card broken? Wad the?

hi all~ last night , i turn on my phone and there's a warning saying sd card broken please format , i 've encountered this problem two times before and i just formatted it because the SD card was rather empty that time and i thought it would be fixed after i format it , but now after downloading a ton of songs i can't afford to redownloading them , so is there a solution and why is this happening?i now use an old 2GB memory card and all is fine so far ..
specs
rom:GDX v21
memory card : 8GB class 10
kernel:stock

My sd card is killing me !!!t.t

hi all ,when i 1st used a rom (any rom )there must be a friggin ton of problem ..so when i updated to GDX v21 i expected trouble, so yes it's a little buggy but i fixed / the problem just went away ..so theres just one problem which is a true , but then this problem is just presistant and i can't fix it ...=( so heres's the problem , the sd(8GB class 10 ) in my phone will say it's damage please format , so i did , but then the whole phone restarts without fixing the problem , so i tried 2 more sd card a 2gb class 6 and a 8gb class 10(?) micro SD card they all started fine but then it encountered the same problem , i faced this problem a week ago and i cant fix it , yesterday the memory was abler to be read and then today it says SD card error again.WTF??? i tried factory reset but it's still there use CWM and wipe dalvik and battery stats , no resolve i cant flash cause my sd card is dead , imma using PCC to flash my phone later but is it cause of SD card problem or isit my phone sd card reader is buggy?

-problem -SD card unable to read (says SD card is damaged) tried 3 diff sd card but all same
-well maybe a little off topic but my DSP manager seems to lags the phone badly when i turn on equalizer for speaker
Is your sd card kingston? I have the same problem, and found out that there is a compatibility problem with kingston 8gb.
SE claims to have solved it with an update but this is for stock rom users. So not me. I don't know if anything can be done and if any of our fantastic (slurp slurp) developers could help.
Sent from my X8 using XDA App
mine is apacer 8GB ...it's so dam annoying i flash back to stock but still have problem i flashed like 6 times now and it's finally ok...can read sd card so far...but still going to the retailer and asking for a refund if the problem occurs

Not able to confirm again ...
There's a 8GB Kingston Class 4 in my X8 which is working perfectly fine since the last 7 months (GDX v021 on Stock Kernel).
However, as there's been another one posting about SD card problems who also has a Class 10 mSD ... I would rather say the phone seems to have a problem with Class 10 Micro SD cards ... given my Class 4 and some Class 6 (if you search the X8 section) work flawlessly.

so i tried 2 more sd card a 2gb class 6 and a 8gb class 10(?)

The 2GB Class 6 _should_ work, given we have some posts around where people use a Class 6 mSD successfully.
But, as I said above, I would be cautious with Class 10 mSD's as there not only yours which gives trouble.
for some reason my phone is a magnet for trouble ...
I spoke to the guy that sold me the card and he told me to go by the store and try with either a kingston 8gb class 4 or an apacer 16gb class10 (that's what he has in store). I guess i'll try the kingston but i'll be away for a week so I'll have answers next week.

Same here mate. Perhaps we shouls start a club.
haha yea...we are really poor souls =(
damn it i tried my sister's sd card ( just to confirm my problem ) i connect it to pc and all is fine ...then i click turn off usb storage and it says blank sd card ...i guess i cant confirm it's the hardware problem
Just as a related note now that I checked back...
The other guy who had about the same SD card problems was using a Verbatim 16GB Class 4. Seems as the X8/W8 is somewhat picky when it comes to the brand (manufacturer) of a SD card and the related class.
As I wrote in that post - either try the card in your phone right there in the shop (if the clerk agrees to it) or strike a deal that you can return the card in case you have severe troubles due to compatibility issues.
as always thanks BJ! you helped me so many times! so yeah i called my dad to send it to the repairman but i doubt it's the sd card problem since the other 2 i tried also failed to read ...it could initially until i restart the phone or connect it to usb then it will get the warning..i suspect its the hardware problem

try format it in your Nokia and using it again in your samsung, but many low end SD cards have this problem, even USB's, they get corrupted and it tends to return to write protected mode ...always best to get a good quality SD card
