My experience with SYS V Release 3.2 is that it won't support more than
1024 cylinders without doing some sort of logical sector remapping. Now
there may be versions from certain vendors that do support > 1024 cylinders,
but the Bell Technologies 3.2 I have used will not. Some ESDI controllers
will allow you to convert 1224 cylinders x 15 heads x 36 sectors per track
into 654 cylinders x 16 heads x 63 sectors per track. The Western Digital
1007 ESDI controller and the Adaptec 2322 ESDI controller both have this
ability.

Also, the number of bad sectors you reported for your drive is very high,
even for a big ESDI drive. I complained when I got a Maxtor 4380 drive
with just under 90 flaws. You might run into the problem with the disk
scanner running out of slots regardless of what version of 3.2 Unix you
get. You might try checking with your vendor about swapping the drive
with one that has a few less errors. MSDOS doesn't care about errors,
so they should be able to resell the drive.... Good luck!
