Ever since I upgraded to the new AKU3.3 Cingular roms, I've been having an issue where my 2GB Sandisk MicroSD Card will just 'disappear'. It can take one of two different forms when it disappears:

1) The card looks like it's simply not there. The OS creates another directory on the device itself called "Storage Card". Ejecting the card and reinserting it makes it visible to the device again, but, then the card itself is called, "Storage Card2", with the obvious issues of all links being broken until I manually rename everything to be what it should be.

2) The card is there, and I can navigate the directories, but, there is nothing IN the directores. Removing and re-inserting fixes this, and all my info is there again.

This is getting REALLY annoying, and only happened since the upgrade to the new Cingular rom. Anyone have any ideas of what is causing the problem, and/or how to fix it?

Thanks!

EDIT:

After working at the issue for a while, here is the end results:

Do the following reg. hack (numbers are in DECIMAL! hex equiv. is 0x2004):
[HKLM\System\StorageManager]
"PNPUnloadDelay" = dword:8196
[HKLM\System\StorageManager]
"PNPWaitIODelay" = dword:8196

Additionally, the Kingston 1GB MicroSD Card is *much* better (Japanese made) than the SanDisk or even the Crucial MicroSD (Taiwan).

I had SEVERE issues with the card going missing; changing to the Kingston SD and applying the above fixes made the issue GO AWAY!

I had the same problem when I used this rom, I think its a bug, I chnaged to the HTC test rom and did not have any issues.

I think you will have wait until the formal release rom comes directly from AT&T, as you know this site will not have roms from next week

I have a SanDisk and it has the same issue. It has issue #2, where the directories are there but no files. It caused my ringtones to go missing. Only since the upgrade to the Cingular AKU 3.3 ROM. Just ANOTHER issue with this ROM.

I have the HTC 3.3 ROM, same prob. 2 situations:
1. card shows gibberish text(signs - not letters)
2. folders are there but no files.

SR always solves the situation.

I just ordered a new Crucial.com MicroSD 1gb memory card. It's smaller than my SanDisk one, but, since I need it to be reliable more than I need it to be big to store music, etc.. I'll take the crucial chip. Hopefully that solves the problem.

I have similar problems, where the card (ExtremeII Sandisk 2GB):

1) disappears, or
2) shows up in the folder tree but reports as having no free space, or
3) becomes temporarily corrupted and hangs the whole system when trying to access it.

Eject/reinsert or soft reset fixes all of these. However, I was having problems 1) and 3) on the old ROM too, and used to see similar problems on my old Axim X50v.
