Hi there, Im trying to set up a maxtor 81gig hd as a 'dangerously
dedicated' drive on my 4.3 stable system. My problem is FreeBSD is
seeing this disk as:
ad3: 78167MB <Maxtor 98196H8> [158816/16/63] at ata1-slave UDMA66.
where the PC's BIOS is seeing:
SIZE CYLS HEAD PRECOMP LANDZ SECTORS
81G 9964 255 39235 63 LBA
and the geometry stamped on the disk is:
CYLS HEAD SECTORS
16389 16 63
Now I can live without the 2 gigs FreeBSD seems to have misplaced but by
the time im done running `exerpt from handbook`:
# dd if=/dev/zero of=/dev/rda1 bs=1k count=1
# disklabel -Brw ad3 auto
# disklabel -e ad3 # create the partition
# newfs -d0 /dev/rad3c
df shows the partition being 70gigs, so now thats 10 gigs lost...
One interesting thing is when I do the newfs -d0 /dev/rad3c I get the
following message:
Warning: 1536 sector(s) in last cylinder unallocated.
Could this be where my 8 gigs are dissapering to? If so how do I get them
back without making another partition? Oh yeah heres a continuation of the
newfs command: I cut it short:
Warning: 1536 sector(s) in last cylinder unallocated
/dev/rad3c: 160086528 sectors in 39084 cylinders of 1 tracks, 4096
sectors
78167.2MB in 2443 cyl groups (16 c/g, 32.00MB/g, 7936 i/g)
super-block backups (for fsck -b #) at:
32, 65568, 131104, 196640, 262176, 327712,^C
thanks for any and all of your advice!
