Well, I would assume(and that is taking a risk) that the unit itself would have that sort of functionality in it, perhaps via a key sequence or something.
If not, I have a multi-card reader that reads 7 different types of memory cards(smart card, SD, Sony's and a few others, including compact flash) and using that, you could use Windows 95(B and C revisions), 98, 98SE, XP(any), Win2KPro and Vista to access the unit and format it FAT(FAT16 as opposed to FAT32 or NTFS) pretty easily. Anything under 2Gig's you'd probably want to format Fat16 anyways. Simple option.
Wait, I'm wrong, 8 card reader. I am specifically using a SanDisc ImageMate 8 in 1. Cost around $30 when I bought it 3 years ago, price seems to be holding steady. I use it with the memory units for my various digital cameras(and those of my family). Neat unit. Comes with a base since the main part is removable. What is cool is that it comes with a short cable so you can take that short cable and main unit on the road with you for use with your laptop. Only bad thing is you better NOT lose that cable!! USB 2.0, backwards compatible with USB 1.1 and 1.2, and requires no driver under XP, Vista and Win2KPro.
Other options could include a similar type unit that can be mounted into an open 3.5" or 5.25" bay on your desktop machine.
Other than this optional purchase, I'd suggest downloading the manual for the Show Designer 2 and I'm fairly positive the manual will walk you through it.
