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. >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. >Fix: 129c129,130 < >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
