Hello; I am not sure if this is the appropriate forum to ask this
question. It concerns the 'disklabel' command on NetBSD (but may apply to
the 'disklabel' command in general).
I am trying to use a NetBSD 1.5.3 live-filesystem CD-ROM to recover files
from a dying HDD belonging to a friend, which runs Windows XP. The disk
lives inside an IBM T30 laptop.
I get NetBSD running -- it works great, by the way! -- obtain a DHCP
address, and mount the destination drive for the rescued files on my
server via nfs. Fine. But I cannot mount the internal hard drive.
fdisk gives me an error "wd0: no disk label" and then prints out the
following:
NetBSD disklabel disk geometry:
cylinders: 16383 heads: 16 sectors/track: 63 (1008 sectors/cylinder)
BIOS disk geometry:
cylinders: 1023 heads: 240 sectors/track: 63 (15120 sectors/cylinder)
Partition table:
0: sysid 7 (OS/2 HPFS or NTFS or QNX2 or Advanced UNIX)
start 63, size 75327777 (36781 MB), flag 0x80
beg: cylinder 0, head 1, sector 1
end: cylinder 1023, head 239, sector 63
1: sysid 28 (unknown)
start 75327840, size 2812320 (1373 MB), flag 0x0
beg: cylinder 1023, head 0, sector 1
end: cylinder 1023, head 239, sector 63
2: <UNUSED>
3: <UNUSED>
Partition 0 there is the ~40-gig partition I expect to see.
'disklabel -r wd0' fails, saying there is no disk label, but I can read
the kernel's automatically-generated disklabel with 'disklabel wd0', which
gives (shortened version):
# /dev/rwd0d:
type: ESDI
disk: HITACHI_DK23DA-4
label: fictitious
<...SNIP...>
8 partitions:
# size offset fstype [fsize bsize cpg/sgs]
d: 78140160 0 unused 0 0 # (Cyl. 0 - 77519)
e: 75327777 63 NTFS # (Cyl. 0*- 74729)
f: 2812320 75327840 unused 0 0 # (Cyl. 74730 - 77519)
If I try to mount -t ntfs /dev/wd0d /tmp/home I get the error "Invalid
Argument".
I have tried to write the disklabel a few times, but it has not succeeded,
possibly because it doesn't know the appropriate fsize and bsize.
Anyone have any clues for me? Or, if there's a more appropriate list on
which to ask the question?
Thanks in advance,
Brandon
