Hello~ Everyone

Could you help me out for data backup?

I was trying to back up data by Knoppix.

I have 4 SCSI hard drives in one server.
One of them installed "WIN 2000 ADV. SERVER" I can see on the Desktop.
However, three others Not installed any other OS I cannot see and mount on the Desktop.

When I used " fdisk -l", I got following messages.


Disk /dev/sda:36.7 GB
Disk /dev/sda doesn't contain a valid partition table.

Disk /dev/sdb:36.7 GB
Disk /dev/sda doesn't contain a valid partition table.

Disk /dev/sdc:36.7 GB
Disk /dev/sda doesn't contain a valid partition table.

Disk /dev/sdd: 9100 MB

Is there any problems with RAID or something?

Could you please help me how to mount them ?
I really appreciate it.
