" Sysv r3 had a 1024 cylinder limit. On IDE drives it was just over 500 megabytes.
" On SCSI drives it was 1g with 512 byte blocks. In order to get over 1g, you
" had to format the disks with larger blocks, so the number of cylinders did
" not go over 1024.
i'm pretty sure this limitation was in the att format itself, not the
disk drivers. i recall reading that the mfm 3b2s couldn't format the
maxtor 1190 et al to full 1224-cyl capacity but had no trouble using
shocked to see i'm named in the friedl 3b2 faq! that must date from 2
decades ago when i was a 3b2 admin at bell labs, which launched my
sysadm career. takes me back...
