PDP-11/23 machine boots fine

I nearly said nothing but last night I was working late on this machine and DID in fact diagnose and reassemble the machine in working order. When I put the skins back on it I must have accidentally toggled the Fixed Disk Ready button on the faceplate. That is all the failure was and when I noticed it after work this evening I could have kicked myself. Anyway, the machine works. I would like to format some floppies and get a restorable backup of the drive. The two floppies respond to DIR/Bad, and Init/Bad as devices DU1 and DU2:. But I get 'bad sector in system area' when I try to init. How do I low-level floppies? -- ----------------------------------------------------------- Jeffrey S.
