I need the format.dat entry for a 3,5 inch SCSI disk drive from Hitachi, type is : DK312C-25. What I found out up to now is: -------------------------------------------------------------- disk_type = "Hitachi DK312C-25" \ : ctlr = MD21 : fmt_time = 4 \ : ncyl = 1074 : acyl = 2 : pcyl = 1076 : nhead = 12 : nsect = 38 \ : rpm = 3600 : bpt = ????? -------------------------------------------------------------- As you can see above, the bpt-parameter is missing. I'd like to know the appropriate value for that drive, or, better, a algorithm to calculate it. The SunOS-Manual says about "bpt": > must be assigned the physical number of bytes per track for the disk type. > This number is used to calculate the boundaries for defects [.....] Any help would be greatly appreciated.

Here's what we use: disk_type = "Hitachi DK312C-25" \ : ctlr = MD21 : fmt_time = 3 \ : ncyl = 1074 : acyl = 2 : pcyl = 1076 : nhead = 12 : nsect = 38 \ : rpm = 3600 : bpt = 19456 Scott J. Kamin {ico, att!uswat, uunet!dunike} !onecom!sjk TelWatch Inc. (303) 440-4756 FAX (303) 938-6703
