So does the "size" indicate whether it is "head" is correct, a floppy is a one-platter disk; to the software it's like every other disk except in number of platters and usable size (in some disks, maybe only older ones, the top and/or bottom sides are not used for data) > 720K or 1.4M?

There are other possible sizes; I think the original PC had 90k floppies. Let me see 8 sectors (IBM didn't realise the drives and media could do nine), 256b sectors (I think) 40 tracks. Oh, there were also single-density 8" floppies, but not on peecees, at least as standard equipment. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
