I have a Flash Drive 32MB capacity. It was a give away at a conference I attended which contained
a PowerPoint file from the show. Anyway, when I plugged in the drive ( USB ) it mounted two volumes identical to each other. The drive is formatted MS DOS FAT 12. I can read and write to the volume with no problems. My question is why am I mounting two volumes ( I've reformatted with no change) and two, why the MS DOS FAT 12 Format? Just questions I have for my own edification.
Do all Flash drives format to MS DOS Fat 12?

That is weird.

I'd reformat it to FAT 32 or Mac OS Extended...after you've saved the PowerPoint file to disk, of course.

Curiously those options are not available in Disk Utility for this drive. It mounts fine on MDD PM
FW 800 10.4.2.

In Disk Utility, are you making sure to format the drive itself and not the partitions? In Disk Utility, it should show up as three names. The highest up is the drive and the two indented ones are the partitions. Select the drive and erase, then set up the partitions. I imagine you did that already but I'm just checking.

OSXRULES: Thanks for pointing out my oversight. Everything in order now.
