This whole X2 case reminds me of N97 when it was introduced. Truly 'spooky' phone

My card is also from today one of those who messes up. My files does not get deleted but when browsing the card from the phone it sometimes contains perhaps two out of the folders, sometimes the files is there (i guess) but folder and file names seams renamed. A look at the card on my computer shows every file/folder/file name intact.

Guys,

You who had the SD-card corrupted, did you install any applications on it that you use frequently?

As you might have read, my card only looked corrupted in the phone file explorer but yes, I installed every application on the card. Most used is S2P and Pocket player and of course all my music used by the apps mentioned.

If running S2P listening to music,the app suddenly halts. I then shuts S2P down and starts file explorer to see what happened the card looks partially deleted or all folder and file names corrupted (mounting the card on PC shows no errors at all).

In the beginning I had Outlook save incoming mail on card but as the card disconnects outlook creates a folder, Storage Card in root of phone. That creates a problem when the phone mounts the card again since it gets named Storage Card2 instead. That messes up all short cuts created by me or phone to the applications installed at the card.

I use card pre packed with phone and I see no reason to try another since others here reports no difference when replacing card.

The moment my card got corrputed
I quit using X2 completely.
I've seen no sense in further struggling and
I also have no time for that.

Why the question?
MR2 also screws it?!

TLDR: Don't install programs or attachments on your storage card.

I am now 100% certain that power management is behind the disappearing storage card issue, and is a culprit in a number of other bugs. It looks like when you put the device into standby, it switches off power to a number of components.

It's easy to see what happens with the storage card if you use SPB Mobile Shell. There's a handy shortcut under Tools - Browse Files - Storage Card. If you put that shortcut on your home screen and come out of standby, you'll usually see the icon return to the default unassigned shortcut. After anywhere between a fraction of and many seconds, the SD card icon will reappear.

Seems like some genius engineer at Foxconn, not knowing much about WinMo or stuff in general thought he was being very clever by saving what, 10mA? in shutting it off. Think of all those extra minutes of standby time saved.

I too suffered from a corrupted FAT, but thankfully all I really lost was MP3s I already had elsewhere. Since I figured out what's going on, I've had no trouble whatsoever. It does of course mean that I've had to make yet more compromises in the functionality of the device. The key is to make sure not to install programs on the storage card, or if you must, make sure the phone doesn't go into standby while running them. Also, don't choose to store email and MMS attachments on the card, or you'll get the Storage Card2 problem.

Stupid power management also explains these other things that have been bothering me, and many of you:
  • Notification sounds and lights not working properly.
  • Sporadic checking of email.
  • Custom ringtones disappearing (Hint: put them on main memory).
  • The phone randomly freezing when trying to work with Bluetooth car kits.

Presumably Sony engineers are aware of this, because if they aren't, God help us. I'm guessing that power management is such a low level issue that it's very difficult to fix with firmware if at all. That being the case, I'm not confident this phone will ever work properly and has most likely sounded the death knell for me for both Sony Ericsson and WinMo.

@bedlam_au

You may be right about power management.
That may be the answer.

Before my card corruption when I was entering SlideView
I always saw it REFRESHING media content,
like looking for it again and again....

have you tried it?
Code:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\State\Suspend]
"shc1:"=dword:00000000

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\State\Resuming]
"shc1:"=dword:00000000
We have been testing it with my friend for a while (since 24th of april) and he hasn't got any storage card problems after applying this *.reg. He had them every time before that.

@ultrashot: I think you've done it! Changed those keys and didn't even need to soft reset. I've been checking all day and haven't seen the storage card disappear once. Presumably it's going to stay that way.

Does someone feel like making up a cab for this? It'd make many people's day.
