Something else I found is that the Nextar Q4 series shares the same issue with one of the the mios on the SEC S3C2410X Test B/D hardware where if you make changes on the SD card then put it back in the GPS without resetting it, it'll corrupt or delete some of the files. The forum post said something about the unit caching the FAT on the card when powered up from a reset.
"I reject your FAT and substitute my own!"
Pop the card in and out with it on (GPS app NOT running) or with it off, but without making changes using some other device (like a computer) and it's happy happy. Change something on the card then pop it back in the GPS without a reset lobotomy and it throws a fit and trashes a folder or a file or two. I doubt it's a general bug in WinCE Core 5.0, I never had such a problem with my RW200, must be something specific to this particular hardware.
Looks like the corruption wasn't the Fuji card, but the TTS stuttering was. I just had to reformat my Lexar card and put Primo on it again because when I went to copy the nicely working setup the POI visibilities and the UnitedStates DEM files were corrupted. *Then* I went searching to find out WTH was up with it. Solved the mystery of why some times it'd lose edits to system.ini or sys.txt and at least once the skin archive vanished and one time it wiped the entire card.
Since Windows guards corrupted files and folders like a mama grizzly bear protects her cubs, a reformat is the only way to eliminate them. I've tried many file killer/deleter utilities and so far none will get rid of them. Proper behavior of an OS towards bad files and folders that cannot be repaired should be to blast them away, not protecting them!
Edit: Did some googling and the mio C310x shows up to windows as a SEC S3C2410X Test B/D. I wonder if its firmware could be put on the Nextar Q4 series? Wouldn't be much point if mio doesn't have a cure for the CD corruption.
