I am trying to format a Maxtor XT-8760S (760MB) drive on a Sun 3/60 (version 3.5 SunOS), without success. My documentation specifies the following disk geometry: 1632 cylinders 15 data heads 54 sectors/track I have danced several numbers with diag (a typical example would be 1620 ncyl, 2 acyl, 15 head, 54 sectors, 1 interleave) but format always throws up on it. If I tell diag that the drive is a Micropolis 1558, it formats fine. (Of course, I lose a few hundred MB in the process.) If anybody has successfully formatted one of these drives, I would love to hear from you. Tom Olin PAR Technology Corp. (315) 738-0600 ...!uunet!adiron!tro

We don't sell Maxtor 8760S drives (the CDC's are cheaper and have worked very well for us), but I have been told to use the following: 1626 data cylinders, 2 spare cylinders, 1632 physical cylinders, 15 heads, 53 sectors per track. There is a jumper on many disk drives that chooses between 1 more or less sector per track, you might check the the Maxtor has one, and set it to 53 sectors per track if so. I seem to recall a bug in earlier version of Sunos that wouldn't allow more than 1400 or so cyulinders, but maybe it's fixed now.
