Here is a strange one for you. (At least I find it strange.) The Seagate ST251N (SCSI) drive has the following statistics: sectors per track 26 data surfaces 4 sectors per cylinder 103 Now 4 times 26 equals 104 so where does that extra sector go? Are they using it for something special? Thanks, Matthew. ==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-==-== Matthew D.

On my scsi disk, the first physical sector is numbered 0, not 1.]

Well, I spent most of Friday installing and low-level formatting
ST-251 disks (ST-506 interface). They've got *6* heads and 820 cylinders.
I suspect that the controller on the HD is lying to the SCSI controller
for some reason.
Maybe those are "logical" cylinders, not physical?
