Pfft, look at all my drives, there is 1..2.. 11 !!
Ok, they're not all physical, G: to J: are emulated drives provided by DAEMON Tools.
S: is a path mapped to a drive (2K/XP use SUBST via CMD), it's much like the amiga assign command.
Z: is my 1024MB (1GB) RAM Drive, just two sticks of 512MB SDRAM.
