Hello, about one year ago I reported a bug in FBSD-2.0.5. My ISC-Unix partition was removed from the partition sector while installing FreeBSD. This error persisted in 2.1 and is also alive in 2.1.5. This time however, I went into depth and found that the wd driver reports the wrong number of cylinders. My AT-Bus disk (Conner 544CP) has 1054 cylinders, but FreeBSD sees only 1053. It is partitioned as: System Boot Sid Cyl Sec Sid Cyl Sec Offset Size DOS-16 (4) No 1 0 1 15 64 63 63 65457 FreeBSD (165) No 0 65 1 15 227 63 65520 164304 ISC-2.2 (99) Yes 0 390 1 15 1023 63 393120 669312 Solaris (130) No 0 228 1 15 389 63 229824 163296 The ISC partition ends on cylinder 1053 (and it exists indeed). However, since fdisk sees only 1053 (0-1052) cylinders the ISC-partition is not completely inside the disk and therefore marked as 'unused'. (Writing the slices leaves me with some handwork to restore the partition table. :-( ) Note that ISC saw 1054 cyls. -- as in the BIOS -- that's why I used them. Any idea why FreeBSD sees only 1053 cyls. or how to work around ? Anything special about the Conner ? Regards, Robert
