Pocket Mechanics told me the card was FAT16 so using the same soft, I formated it in FAT32... Maybe it'll help..

I've had the problem with the same card formatted both ways (as FAT16 and FAT32).

Just use S2U2. No SD card isssues when using it because you can blank the screen instead of sleeping.

What's the difference in battery performance between blanking the screen and sleeping the phone?

I have not had memory card issues with the Touch.

I haven't noticed any.

Can you tell me what settings i should enable for this?

Is it: "but Blank Screen only" under "On Battery Power" and "On External Power"

or

"Don't Suspend Power" under "Advanced"

Discovered a path related problem
 

Well, it finally happened to me... I lost the files on my SD card - previously, all I had to do was eject the card and re-insert, and my files would show up... But not last night.

So, I decided to figure out what had happened... Since data recovery is just one of the things we handle at work, I fired up some applications to figure out where my data went. I assumed that the data was still there, but just no longer visible - similar to when, with Windows 98, if you powered off improperly, your drive would think you had less data than you did, and a scandisk fixed it...

Ran the utils, and all 350MB of files I had thought were gone were sitting right there - the recovery apps said they were right there - I should see them. Until I looked at the PATH... Turns out that something is going wrong with the path structure, the files that were missing were in the "." path... Confused?

Let's say the root of my SD is the "I:" drive... So
I:\Blah.file is where my files were...
But now, they were here:
I:\.\Blah.file

Still there, just in "." - and of course, you can't access that! So I simply had it move the data back to the root, and viola - all my files, no corruption, no lost data.

I decided to do a chkdsk on the card, to see if anything had gone wrong other than the data (it was 5AM and I didn't want to do a full byte scan with the recovery apps). XP's chkdsk reported that the path structure was invalid, and even noted that "." and ".." were wrong, so it corrected them! WARNING - DO NOT DO THIS IF YOU HAVE DATA, XP/VISTA CHKDSK WILL NOT RESTORE YOUR FILES THIS WAY, IT WILL ONLY CORRECT THE BAD PATH, BUT YOUR FILES WILL NOT COME BACK. And, funny thing, it said I had CROSSLINKED FILES! Now that's weird - and the only time that really happens is when write processes are interrupted...

Anyway, for people that have important files that they think they have lost, they can probably be easily recovered... Just do NOT use standard operating system tools to fix it, since they probably won't...

From what I've seen and has been previously posted, the problem is that the cached FAT table becomes corrupt. So if/when the device tries to write to the card after the problem starts, it can overwrite valid data. This is why sometimes you can reset your device and all is well, while others...

The first one.

I am using S2U2 configured as described here and still have SD card issues several times each day.

I can verify also that I'm getting errors with the "but blank screen".

I tried the advanced option and haven't had errors yet but I need to wait and see.

I changed this setting under Advanced in S2U2 and went nearly a day before having a problem again.

I have experienced two variants of this corruption issue: 1) my SD card root folder structure is there but all root folders are empty (I was getting this several times a day prior to making the change noted above), and 2) the card shows several dozen folders and files with garbled names. This is what I just experienced.

I had lots of problems with the SD before installing s2u2, but now that everything (including s2u2) runs from main memory and the SD is merely a backup/repository, the phone is very stable, and the SD has not needed any help in a couple weeks.

After two days, I finally got a corrupted SD card with the advanced feature ticked on too. This is getting really annoying!

I don't (and with the Touch, never have) run any apps off the card. I use my card only to store audio books, podcasts that are sync'd from my computer, cab files for reinstalling, and backups.

I'm back at square one with this issue since everything I've tried has not caused it to stop.

I don't think that s2u2 is the cause of your problems.

The card gets corrupt when WM tries to access it while sleeping. It does not matter if your device is falling asleep because s2u2 is telling it to, or via the power settings in WM. The same corruption will result...

You missed the point. With the correct S2U2 settings, the phone never "sleeps", it simply blanks the screen.

Using S2U2 as described above, does the phone *never* suspend - even if the power button is hit. Or do those settings only change how the phone behaves if it turns itself off (after being left alone for a minute, for example)?

Add me too the list. My card got corrupted 3 times within a week and it seemed to happen when I installed Sprint's Mobile Email and enabled my Yahoo account. I always chose SD card to store attachments and after the first couple sync's with yahoo my card wasn't readable and everything was "gone". I say "gone" because when I check the amount of storage free in the card from the computer, it shows that its still almost full. So like mcw said in post 88 its still there its just messed up. I had the phone replaced but I checked the sofware and firmware of the new one and its still the same as the old one. I never installed mobile email this time and everything was fine until.....my photo album won't stay open. I think I have to many pics (approx. 90) in DCIM\100MEDIA folder because when I click on pics, the album starts loading and after two rows are loaded it just returns to the home screen. Anyone have this issue. It stopped when I deleted half the pics in that folder.

Ok, been folowing this thread ever since my SD card crashed on me and is a garbled mess. Is there any hope of recovering my data. Not so much the music downloads that i paid for, but the many photos i took and had yet to backup. I never thought my saved photos on my sd card would get erased. Any recovery tools that can sucessfully recover the data from my card or should i just forget about it and move on?

I just posted on the official Sprint forum - we need to let them know!!

I posted over there - we'll see what happens. The link you posted wasn't correct, though.

I solved my own problem with the photo album. There was one photo (a jpg) that would close photo album for some reason. First I removed all the pics from \100MEDIA with Total Commander. Then I moved them back into the 100MEDIA folder 5 at a time and opened photo album to check if the bad photo was one of the five. And wouldn't you know it, the corrupted photo was one of the last five I moved. After I deleted that one everything was fine.

I've had the problem of garbled and missing folders 3 times in the past month.
Soft-reset only worked once.
I woke up with it this way today.
I can't even delete the garbled folders since it thinks they're system files or read-only.
I even booted into Safe Mode with iLauncher and tried to delete them but it still won't work.
I guess I'll need to copy over to my PC what I still have, format, and copy back.
I hope they get a hold of this.

Well...kept on having data corruption problems, but soft reset would "fix" it...but tonight, it didn't...so I had to plugin my MicroSD card into my PC and run GetDataBack in order to retrieve its contents...looks like I'll need to keep a daily backup on my PC in case stuff happens like this...

No, you missed the point: S2U2 has nothing to do with the corruption. The device can be put to sleep with the WM power settings and/or power button.

Besides, even if you did manage to leave the phone "awake" all the time, you'd end up with a battery life of merely a few hours - hardly a solution!

You couldn't be more wrong.

about what?

The thing that has helped my corruption is that I removed my nightly backups. Therefore if the card is grabled, you wont write to it without your knowledge. Therefore a soft reset always fixes it. Then I manually run a backup 1-2 times per week and copy to computer for safe keeping.

About everything. S2U2 doesn't kill the battery and it sounds like he wants a medal for figuring out that you can turn the phone off via the power button. LOL

Before S2U2, I would get corruption of my SD card every time I used CorePlayer to play MP3s over A2DP. Since S2U2 and the power settings, I've had zero issues.

Wow - sounds like someone got up on the wrong side of the bed!

Once again, my point was that S2U2, if installed to main memory, is not the cause of the SD card corruption.

There are lots of people on here, myself included, that run it with "zero issues".

I think hippitys understands that s2u2 is not the issue- we are all using it as a temporary fix to try and keep the device awake by using the blank screen option. While this does slow down the the occurance of the corrupt card, it doesnt solve it for me.
I dont think anyone is blaming s2u2.

2gb card and no issues. I have my weather panel (phat phingerz) program on the card, my music, and ll of my 20+ games installed on my card and have had no issues. This is the card I previously had in my Mogul.

Correct. I believe that I'm the one who introduced it to this thread specifically for combating the SD card corruption problem.

I had this problem when I first got my touch -- every few days the bundled 512mb sd card was corrupted.

Since then have hard-reset and then soft-reset the device just before the sprint garbage is installed. Also put in a new 6GB sandisk sdhc. For 3 weeks now I have had no issues -- not proof yet, but at least its looking good so far. If a few months go by with no issues I will call the problem solved.

is anyone having problems when NOT running with the sprint bundled software?

Also, anyone having corruption problems with an sdhc card (6GB or higher) ?

I have a sandisck 6GB sdhc and am seeing corruptions daily..

As retrobits asked, are you guys allowing Sprint's customizations to install?

I personally don't think it matters (I have all customizations installed and I've never once seen any corruption) but its always best to get the full spectrum of the situation instead of just the problem itself.

I was using a 6gb sdhc and did not have anything installed from ExtROM when I was having problems.

I have had two Sprint HTC touch and i too have a problem with the stock memory card. files keep disappearing and some times just mysteriously reappear. then some files looks curruptedwhen i veiw them on the card. i recently got these phones in november.
