I've got a very strange problem with my external 3.5" floppy. I took it over to a friend's house, and after I got it hooked back up to my system the next day, I discovered that disks formatted in drive DF1: could not be read in DF0: (and vice versa). A disk formatted in one floppy reports "DFn: BAD" when it's inserted in the other drive. The really strange thing is that all of the floppies I've already formatted can be read or written by BOTH drives without any trouble. I would suspect that the alignment on my external drive got bumped. But that should also foul up reads & writes, not just formats. Is it possible that something inside that Amiga is dying? Any other suggestions? Diskcopies also are broken, but file copies work fine.

Diskcopies also are broken, but file copies work fine. There's not much in the Amiga that could cause this problem, since the Amiga makes no distinction between formatting a floppy and normal writing. I suspect some mechanical mis-alignment just enough that the fringes from the previous data are letting the other system get a handle on the data, but it's too far off for a clean disk. Pretty wierd in my book. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
