I have recently obtained some HP97548S/D SCSI drives that I intend to connect to a SPARCstation. But I need to create a format.dat entry, since none was included in Sun's standard format.dat. The main parameter I am having problems with is bpt (bytes per track). This drive has 57 sectors per track (56 for data and one spare). However, looking at other SCSI drive entries in the file, the relationship between number of sectors and bytes per sector isn't obvious. I'm wondering if I need to use some number other than 512 bytes/sector. Has anyone out there used these drives on a Sun, and have the right set of parameters? I am getting some errors when I run format (trying to access an illegal block) and I don't know if it is due to problems in my format.dat entries or something else. Any info appreciated....
