Compact flash cards issues may cause high CPU activity
Authored by: macmouse on Dec 16, '07 10:16:44AM

You do realize, that most flash devices (Compact flash, USB thumb drive, Digital Cameras) use FAT32 for their filesystem because it is the most compatible (between mac, windows and linux). So unless you have reformatted the disk using Disk Utility, it is still going to be FAT32. I have yet to have heard of a digital camera that didn't use FAT32, and when inserting a different filesystem (HFS, NTFS) the camera would refuse to work because it could not understand what was on the memory card, and therefore not be able to save the images to the flash disk.

Under the assumption that your flash drive IS formatted using FAT16 or FAT32, then probably the reason fsck_msdos is freezing is because the filesystem on the flash disk has become so corrupt that it doesn't know what to do with it. You can do a search on macupdate.com or versiontracker.com, and there is a number of programs that will do data recovery off camera flash cards, if the pictures are that important to you.

I would also recommend you get one of those "12-in-1" (or heck, now 52-in-1!) USB flash card adapters, and access the card directly because you know your camera is defective, and it is possible that the USB/flash circuitry is defective too (but operates well enough to let you see /some/ stuff).
