Those you can't really change. They look good.

I'm not sure if these #'s are right. This is for a 1 GB Jaz, isn't it?
The number of bytes on the disk is sector size * sect./track * tracks/cyl
* # cyl. For this geometry, that number comes out as 512*32*1*1018,
which is more like 16 MB, to 1GB.

With the usual definitions, # heads == tracks/cyl. So try tracks/cyl ==
64.

With SCSI Disks, the geometry really doesn't matter. So just go for
(sect/track, track/cyl) = (32, 64) (I.E. one of the two is 32, the other
is 64) and things should go well. N.B. You then get 1 MB cylinders.

2k per inode is the default, and seems ok unless you're making a news
server (lots of little files).

Take care,
