Description asherrod 2000-04-10 03:50:04 UTC 
This problem existed in wd.c and was carried over to ata-disk.c.

I have been told over and over it is not a "real" problem. Asking 
various users, I have discovered that I am not alone in experiencing 
this. Of course, others just followed the "Well, add a DOS partition,
and let Microsoft fix your problem" advice. But it IS a problem.

Whenever I install I have to go back and re-write the disk driver then
re-run newfs, etc... It is a problem. It can be fixed (easily).

My drives are not antiques or that unusual. One Western Digital, one
Maxtor. Okay, cheap disks, but not uncommon.

The problem: Not all disks return 16383 cylinders to indicate LBA mode
must be used. Mine return 4192, which rsults in rather small disk sizes.

Fix:

How-To-Repeat: Boot the system with one of the disks in question. Try running 
/stand/sysinstall. Look at how small the disks just became.
