Install of AHA2940U made my linux crash...

[markov at tele2.be]

I plugged in the scsi card and it seemed to recognise the card
under ydl3.  Then when I connected a disk(power off), I got kernel panics
and could no longer boot.  So I installed the system on an extzernal
scsi (not Fast wide, I do not have such a box..)

It works OK, but when I try to repair the internal ydl disc  I get::
[root at localhost root]# fsck /dev/sdc
fsck 1.27 (8-Mar-2002)
e2fsck 1.27 (8-Mar-2002)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdc

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

[root at localhost root]# e2fsck -b 8193 /dev/sdc
e2fsck 1.27 (8-Mar-2002)
e2fsck: Bad magic number in super-block while trying to open /dev/sdc

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>



In fact, the disc is ext3, see here:

[root at localhost root]# pdisk /dev/sdc
Edit /dev/sdc -
Command (? for help): p

Partition map (with 512 byte blocks) on '/dev/sdc'
 #:                type name      length   base    ( size )
 1: Apple_partition_map Apple         63 @ 1
 2:     Apple_UNIX_SVR2*swap      401408 @ 64      (196.0M)
 3:     Apple_UNIX_SVR2 untitled 8065728 @ 401472  (  3.8G)

Device block size=512, Number of Blocks=8467200 (4.0G)
DeviceType=0x0, DeviceId=0x0
Drivers-
1:  23 @ 64, type=0x1
2:  36 @ 118, type=0xffff


So I did::

[root at localhost root]# fsck.ext3 /dev/sdc
e2fsck 1.27 (8-Mar-2002)
Couldn't find ext2 superblock, trying backup blocks...
fsck.ext3: Bad magic number in super-block while trying to open /dev/sdc

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

What can I do now??


I fetched this card in French Bric a brac shop, what is it worth??
It gives this output with dmesg:
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
        <Adaptec 2940 SCSI adapter>
        aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs

  Type:   Direct-Access                      ANSI SCSI revision: 02
(the disc is not a scsi wide, so it is slower than the aha2940U)
