That wouldn't help you. It's already failing at the very first sector, by not finding any address mark at all. Thus using one of the »over-formatted« (like fd0.1720) devices wouldn't help. > The reason I think they might NOT be damaged is that they > are all of the same type (different type from the floppies > I could read), and they are all "double density" floppies. Well, if you really mean "double density", it wouldn't require a higher density device but a /lower/ density one. The default device is using "high density" (2000000 bytes raw medium capacity), while DD media were 1000000 bytes raw. So you could try using /dev/fd0.720. > My question is, how can I do the equivalent of opening, for > example, /dev/fd0.1720 (in -stable) under -current? You just open it, and it will magically appear in /dev. :-) [I've got a huge patchset here that will autodetect DD vs. HD floppies, but before i'm going to commit it, i have to upgrade my box first to -current. This will also change the policy regarding additional /dev/fd* devices, and i'll eventually upgrade the man page as well.] -- cheers, J"org .-.-. --... ...-- -.. .
