Cannot access most storage card files

[dc]

I am using a Sprint 6700 with an AKU 3.5 ROM. I have a 2GB SanDisk Mini-SD card that I've been using successfully for over a year and all of a sudden most of the data on the card is unaccessible. For example, there are numerous MP3 files on the card, but I cannot access them or see them no matter what application I try (media players, file explorer, Total Commander, etc.). There are a couple of visible files like my Outlook inbox attachments, Live Search cache and my picture storage, but that's about it.

I tried to add MP3 files to the card, but it runs out of space. So it appears the files are still on the storage card and taking up the space, but there is no way to access the files. I also have applications like .NET Compact Framework 2 on the storage card and while I can't view this application, Live Search works (it wouldn't work if .NET CF2 wasn't available).

Any suggestions? I was hoping I wouldn't have to reformat the card and have to add all of the files and applications all over again. A friend who has a Verizon 6700 had the same issue, but his files started showing up again out of nowhere and he didn't do anything to try to fix the problem. I have had this problem going on two weeks.
