If that information 140 is not available, use the information provided in your disk's manual. 141 Please note that the geometry printed at boot time is preferred. 142 143 IMPORTANT NOTE: due to a limitation in the disklabel(8) program, the 144 number of cylinders on the disk will be increased by 1 so that the initial 145 label can be placed on disk for editing. When the disklabel editor appears, 146 make absolutely certain you subtract 1 from the total number of cylinders, 147 and adjust the size of partition 'c' such that: 148 149 size = (sectors per track) * (tracks per cyl) * (total cylinders) 150 151 Note that the disklabel editor will be run twice; once to set the size of 152 partition 'c' and correct the geometry, and again so that you may correctly 153 edit the partition map. This is to work around the afore mentioned 154 limitation in disklabel(8).

So, we've given ourselves 221 # an 'a' partition, which is the minimum needed to open the disk 222 # so that we can perform the DIOCWDLABEL ioctl. So, once the 223 # initial label is installed, we open the 'a' partition so that 224 # we can fix up the number of cylinders and make the size of 225 # 'c' come out to (ncyl * ntracks_per_cyl * nsec_per_track). 226 # After that's done, we re-open 'c' and let the user actually 227 # edit the partition table.

This program can determine 488 some limited information about certain specific types of HP-IB disks. 489 If you have SCSI disks, however, prior knowledge of disk geometry 490 is absolutely essential.
