Hello everyone!
I have a feeling I'm missing something very obvious here, but
I sure don't know what it is :\. -- trying to install a Quantum 540 IDE
drive, and mount it under /usr2. HD is installed as primary slave, no LBA
junk,
looks fine in CMOS. Formatted and fdisk'ed it in dos, no problems (made a
primary dos partition ~40Mb). Everything looks good, but I get the dreaded
'Incorrect Super Block' error when I try to mount it:
/ ROOT> mount /dev/wd1a /usr2
/dev/wd1a on /usr2: Incorrect super block.
As I said, this is probably simple, but I'm at a total loss.
Following is the fdisk and disklabel info. Sorry about the length of this
post, but I really thought I'd done everything right. (and looked through the
mail archives, FAQ, etc.) Please email me if you can shed some light on
this, as I don't subscribe to the mailing list. I'll post a summary if it
would be useful for some other newbies out there.
In Freebsd, after some tweaking:::
/ ROOT> disklabel (-r) wd1
# /dev/rwd1c:
type: ST506
disk: ESDI/IDE
label: MBR based label
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 16
sectors/cylinder: 1008
cylinders: 1049
rpm: 1
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
a: 972800 83664 4.2BSD 0 0 0 # (Cyl. 83 - 1048*)
c: 973728 83664 unused 0 0 # (Cyl. 83 - 1048)
d: 1057392 0 unused 0 0 # (Cyl. 0 - 1048)
e: 83601 63 MSDOS # (Cyl. 0*- 82*)
------------------------------------------------
/ ROOT> fdisk /dev/rwd1d
******* Working on device /dev/rwd1d *******
parameters extracted from in-core disklabel are:
cylinders=1049 heads=16 sectors/track=63 (1008 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=1049 heads=16 sectors/track=63 (1008 blks/cyl)
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 0 is:
sysid 6,(Primary 'big' DOS (> 32MB))
start 1008, size 82656 (40 Meg), flag 0
beg: cyl 1/ sector 1/ head 0;
end: cyl 82/ sector 63/ head 15
The data for partition 1 is:
sysid 165,(386BSD)
start 83664, size 973728 (475 Meg), flag 80
beg: cyl 83/ sector 1/ head 0;
end: cyl 1023/ sector 63/ head 15
The data for partition 2 is:
<UNUSED>
The data for partition 3 is:
<UNUSED>
