For an 80 Meg drive ? Hmmm, I thought PC's could only go up to 32 :-) DPFormat was writing data and reading it back, to each track; that does take awhile. Especially since its sending it through the Bridge link, rather than calling whatever bios rom routine the PC usually calls. >Everyone, I suppose, is expected to become Registered Developers? Nope; not everyone qualifies. Some docs are in the Bantam AmigaDOS manual; we are including a bit more in our 1.3 manual. Sorry you had problems; also, sorry you spent 2 days steaming; however, if your still hot now, I guess it was the right idea :-) andy -- andy finkel {uunet|rutgers|amiga}!cbmvax!andy Commodore-Amiga, Inc.
