Panasonic has a download-able formatter that claims to do it right.

Here's the deal. Apparently, if you repartition (before formating) a flash drive and that removes any unused, beginning areas, it may trash your Flash. How? By getting it out of "alignment". That's what the blank areas before your partition; on some of these (SD) cards, are doing! That is setting the proper alignment, and thus the reliability. If you do not record the details and then repartition (which some formatters do automatically) then you lose stability. There's no easy way to fix that.

...and click "Formatting" Then see "Conclusion" near the bottom.
Flash drives (memory cards) are obviously not physically like spinning drives are, internally. They emulate SCSI drives and thus act like (other) hard drives. Many utilities thatt are not made for Flash, will trash your Flash.
Formating, in a device such as a new SD HC(just one of the SD 2.0 specs) camera would seem the best way to format. I'm guessing, they do NOT mess with alignment OR do other things that a given PC formatter might mess up. What other things? I now read, Windows formats a Flash like a Floppy; where there's no partition #1, just the One whole drive. It's like sdb rather than sdb1. That could kick out (reject) your Flash; on certain devices. It's compatibility issue. The idea was a standard, right?
Of course, our DSTT's do not format, in cartridge. How many of you also repartitioned your Flash when you reformatted (discovering FAT32 is slower; for example) only to mess up your Flash "Alignment" and got corrupted files and other incompatibilities. Who know a SD 2.0 format was unique?!
OTHER TECHNICAL INFO:
So you probably know, FAT16 is faster and today, we use VFAT16, right? Everything 2GB or less is going to come with VFAT16; no problem. Everything 6GB and over is going to have to be SDHC, with (V)FAT32 and, require a SDHC reader (a good quality one too, perhaps not the one you got with the DSTT, and you may have to try Three or more). The DSTT's menu is too slow with VFAT32 for me. I don't not know if the DSTT team can or will be able to fix that speed. FAT32 has more overhead but it is a newer file system. That leaves 4GB or less.
OK so, 4GB Flash is in the middle. With SD, it can be a non-spec large 4GB SD that new cameras are made to reject. Else it can be the SD 2.0 spec SDHC type(High Capacity = HC). I don't know what uses a non-spec 4GB. So, I would avoid them. They are probably not as fast, anyway.
Also, 4GB flash uniquely, can be either VFAT16 or VFAT32; unlike higher capacities. Lower capacities (256MB RAM and Win 2000 will not be much fun under 256MB RAM either). You might be able to squeak by with Xubuntu OS at 128MB RAM but it's TIME FOR AN OVERHUAL, as Jim Carrey said. Meaning, it's time to beg if you have no funds. You can do it!
3. The 2GB FAT16 files size limit was due to the old max. Thus the file limit is now about 4GB (unless you run those old unsafe Windows above).
4. Keep in mind the the file size limit of VFAT32 now, is almost 4GB too, even though the partition size tops out at 32GB (until extended). So, you would not be able to record over a 4GB movie in one file, on a bigger than 4GB flash with FAT32 anyway. Got it? My new "still" camera records 16:9 VGA 848x480 video at 30fps ("Quicktime" wrapper) for a whopping 38 mins when given 4GB. See, so either way, I'd have to check it at 38 mins. Other video formats would be less than 38 mins (at once, on any SDHC flash). So the real advantage to bigger than 4GB is only, you would not have to pop in another 4GB card. You would still have to start a new recording segment. Back to the DSTT... One could get more games on one card but I would not like the FAT32 speed penalty.
5. So, the question of the day seems to be, would a newer and faster cards, override the VFAT32 speed penalty that is required on 6GB SDHC and up?
Are we having fun yet?
P.S. OK now, I read that these (new SDHC) cameras, which are supposed to be best at formating safely (Some pros format to erase) have a problem. They apparently do not gauge the end of the partition correctly and once full, your last file locks up the drive (as it writes past where it is supposed to) and requires computer help to repair. You lose (at best), that last file. I filled up the tiny internal (usually slow) memory with no problems but not my Flash card. be advised. You might want to run some tests filling it up. You could lose a long, big movie files and that would stink.
I wonder if the DSTT crashes; when filled up too? Your game save files, could tip it over. I wonder which SD cards, sizes and standards are most affected.
I hope this help track down any glitches you may have. Just, FYI.
