Here is the trick:
-Load WM5torage in main memory
-Disconnect the PPC from the PC
-Make sure all programs running on the storage card are stopped
-Disable the radio (just to be safe)
-Run WM5torage and activate
-Plug in the PPC into the PC
-The storage card should show up as a USB drive
-Copy what files and directories you can to the PC in a backup location
-Go to the Command Prompt on the PC and run CHKDSK on the card (CHKDSK E: /F)
-Do NOT convert bad data to files. Let CHKDSK delete them.
-See if you can delete the bad files and directories. If you can't, reformat the card to FAT 16, and copy the backup of the good files back to the card.
-Eject the USB device from Windows and disconnect the PPC from the PC
-Deactivate WM5torage
-Soft Reset your device
-Reload missing files as needed from good backups
