sd card keeps unmounting from the g1

I don't know why, but at least once a day my sd card unmounts from my g1. I can't see pictures, use the camera, listen to music, and whatever else requires an sdcard. It's fine when its connected to my PC, it never unmounts itself.
Ive search google, this forum, and other android forums but came up with nothing. Only found other people with the same problem but no solution.
Its really starting to bug me and I'm not sure if its my sd card or my g1, any help would be appreciated..
i have rooted rc33 with jf1.41 with release-keys (watever that means)... this was happening before and after i installed jf1.41 with root.
sometimes it comes back if i take the sdcard and put it back in, but other times im forced to reboot. ive also had a few pictures got deleted by themselves, sounds like a fault in the sd card right?
thanks in advance

I would backup whatever is on your sd card. Then format it, fat32. See if that fixes it. If not call up Tmobile and see if they send a replacement.

Ensure the cover is all the way flush, this happened to me and I had to rub the cover from the bottom up to make it sit flush. If it is not completely closed, it will think you pulled it open and unmount the drive.

its already frmatted n fat32, but ill try again..
for the cover, ur talkin about the plastic thing that goes over te sd port right? that has a sensor?

I had the same problem so I opened the cover and closed it. Voila my card showed up again. I hope its not a continuing problem, but it sure beats trying the get the card out and putting it back in.

Anyone noticing this problem with their slide?

So my g/f just got her slide today, and as we were playing with it throughout the day, we noticed that after a while, the phone would no longer recognize that it had a SD card installed... we'd have to pop the back off, pop out the SD card, then put it back again for the phone to recognize it again. However, after a while, the phone would once again say that the SD card is not connected...
Is this a problem with this specific phone, or is anyone else also experiencing this problem as well?

By any chance was it wiping your phone everytime it did that?

I had that problem with the mytouch 1.2 but not with this yet. I've heard using a class 4 or 6 sd card fixes it but I never tried it.

Nah the phone and all the info in the card seems fine, its just that the phone can't seem to find the card once in a while until you take out then put back the SD card :/

take the phone back and swap it for another one at the store. You could also try getting another SD card. You most likely just have a bad SD card. It happens. I would swap the phone first cause its free (since you already paid for it) and would without a doubt tell you exactly what is wrong.

Sounds like a defect I had my slide since may and this never happened take it back and replace it immediately

Ok replaced the phone this afternoon.. problem seems to be solved thanks for the replies all!

Rooted once just fine... Rooted Twice Slap My Face ARG!

So, I rooted my phone perfectly fine, no problems, it caught after 5 times trying. My wife's phone on the other hand will not catch for the life of me. I have been at it for 4 days now, I am pushing almost 1000 tries easily. I do not know why my phone worked out great, yet my wife's phone is being a *&^$%!! I uninstalled Sync and PDANet and reinstalled again and it will only catch "offline" once maybe twice. Any idea? I can catch my phone time after time after time again. Wifes phone, I wanna pull my hair out!
Well any help would be appricated, otherwise, I'll continue pulling my hair out and trying to root her phone....

Try putting your SD card into her phone... not sure why, but the SD cards are making a difference for some of us. I tried a bazillion different things, but had my ADATA sd card from my G1. I formatted the Samsung SD that came with the phone, popped it in, and BAM, first try it worked... just a suggestion though, as this doesn't work for everyone.

I can confirm that the SDcard trick worked for me too.
I followed fermunky throughout his posts on other threads as I was having the same issues.
used the 8gig i got with the phone, formatted it in a card reader, and boom first try.

Cool to hear. For others reading this, remember that this is working randomly, so don't be surprised if it doesn't work for you.
With that said, I wonder if someone can explain on a technical level why a different SD works for those of us...

Thanks for the replies, I did do that tho. I put my SDcard in her's, I formatted her SDcard and tried again, I formatted my card "after it failed" and tried it, I had an additional 8GB SDcard that i tried, I tried no SDcard while trying to get it to catch loop. It just will not catch but once or twice. its bazar.

Stupid SD Card.

My sd card is saying Blank SD card. Sd card blank or has unsupported filesystem. I tried to reformat on phone but still nothing. Any ideas?

have you tried removing and putting into a computer to see if you can access it?
if that doesnt work then somehow it got corrupted or it went bad.

Yup the computer doesn't recognize anything at all. I put it into a camera and it says need to be formatted so I do so and it just stays on a screen saying Formatting. IDK whats going on with the stupid thing. Sent HTC a email and maybe they might send me one or something. Who knows it's a shot.

Sounds like its dead. I would just pick up a new one. You can get a 16gb class 6+ for under $30 online.

I love HTC so much! Sent an email out last night, got one back today and they are going to send a new one. Just have to send old one back. Hopefully they wont see my custom roms on there lol. Any ways HTC saves the day once again and I get a good ol 8gb card back.

i would still buy another. there 8GB is straight up Class 2. Barely writes over 2MB/sec. You can buy a class 6 8GB card for less than $15.00 on Newegg shipped.

Hey OP did you lose all your data?? Hopefully night. I think i might just copy my sd to my external tonight just as a backup that you said this...
Thanks...

Inesplicable deletion of files

Looks like the phone, inexplicably deleted all the directories and files that were stored in my 32 GB Class 10 Lexar micro SD card. It happened once, a few days ago, and today I was at the point of listening to some mp3s when I realised that it happened again today, although now only the "music" directory was deleted.
Does anybody have an explanation?

Which rom, anything suspicious installed, anything new installed, rooted, connected it to a different computer, anything else which might help others to help you?
Also, wrong forum.

could be faulty card. also make sure you do not just eject the card from phone and/or computer without first properly unmounting it.
if it is a new card, or you do not care about data on it, reformat with this tool
https://www.sdcard.org/downloads/formatter_3/

Well, I'm on stock ROM KI4 (Android vers. 2.3.4), my phone is unrooted and I never touched the card since I first put it in the phone, 2 months ago. However the first time I had the unpleasant surprise to find all the directories deleted I was on a previous ROM (android 2.3.3), so it seems that the issue is not ROM dependant. I do have quite a few apps that I downloaded from forums and therefore may be suspected to play tricks. It may be these, or it may indeed be compatibility issues with the micro SD, but what seeems strange to me, is that I don't get errrors in reading or writing files on that memory, but simply all of a sudden, at the point of opening a file, I realize the file no longer there together with its entire directory...
Ok, I was just wondering if I was the only one experiencing this issue, and as it looks so, then I'll keep monitoring the situation to see if it happens again, in such case I'll try to investigate more deeply the possible causes.
Thank you both for the useful sugggestions, and kreoXDA for the link to that utility... It may become handy!
And sorry if I am in the wrong forum (am I?). I thought that this was the right one.

If you haven't already, I would strongly recommend checking your SD card using h2testw.

No actually, I haven't... thank you, I'll do it!

There's a similar program, SDCardTester, in the Android market, so you can test on the SGS2 itself.

Ok, that would a more significative test. And it will let me test the card even now that I am away from home and I have no access to a PC. Thank you.

If you bought a 32gb sdcard off ebay at a knockdown price then I suspect you have been conned.
Try the sdcard test as suggested, it is probably a 1gb card with false code.
If it is from ebay, Dont return item either as recorded delivery will be too expensive, greater than cost of card, phone ebay and they should refund you.

No I'm quite sure that the card is not a fake. I have been using it for 2 or 3 months, filling it almost fully with no problems of capacity, speed, data corruption or whatsoever. Yes I bought the card from ebay, but from a well respected seller at "normal" price and it definitely came sealed by the manufacturer in its original blister.
I've just tried testing with SD Card Tester and everything looks OK. I get about 10 MBps r/w that if I'm not wrong is compatible with the class of the card.
I'm suspecting more android or some malware, rather than the card or some incompatibilty issues, to have erased all its contents except one directory with 5 pictures in it.
Well, as I said, for the moment I think the best thing I can do is simply to keep monitoring the situation.
Thank you mates anyway.

You need to do the capacity test...

I have been having a similar issue with a genuine 16gb class 10 from kingston. Files dissappearing or beconing corrupt. Assuming its a faulty card but not had chance to check.

Me too... it's not easy to perform an exhaustive test...

And here we go again... yesterday I noticed that all the apps that were installed on the sd card had gone... this thing begins to hurt my nerves...

Are you sure the files are deleted or did the as card just unmount?
Happened to me and I just restarted phone, all good.

In fact, that's the first thing I suspected, but unfortunately unmounting / mounting the SD card, even phisically removing / reinstalling it from the slot, and shutting off / turning back on the phone didn't solve the problem...

Well just to give some more info. Its def not a mount/unmount issue as the card contents become corrupt randomly. Im just wondering if its a spec issue as in is class 10 causing a problem. My card is being swapped out by kingston so i will update when I can.

Yet you still haven't followed the advice in the thread, which was to run h2testw or SDCardTester to check the true capacity of the drive, and ensure data written to is is not corrupted.

I too face this similar problem. Use a Nokia 8gb card, don't know if Nokia manufactures it or not. Anyway, my files get deleted too. Apps also get corrupted. Is this a sd card slot problem. Maybe it's faulty?
