It's been a long time. I think we still do the bad144 format sector sparing for these drives. To quote the man page: The format of the information is specified by DEC standard 144, as follows. The bad sector information is located in the first 5 even numbered sectors of the last track of the disk pack. There are five identical copies of the information, described by the dkbad structure. The rest is in the man page. You run bad144, and it does it for you, assuming the system got your disk geometry right. Greg -- When replying to this message, please copy the original recipients.
