Lightbulb mount secondary harddrive.


Hai everybody iam working in an organisation as a Linux support.
My question is one of my users was using open suse on his workstation (690 DELL),there are 4 harddrives connected to the machine one is of 160GB and the other three are of 1terrabytes.His 160GB HDD got corrupted the one which is having OS and we replaced it to the new one.User advised to install RHEL 5.2 so i installed RHEL 5.2on 160GB HDD by disconnecting the other three HDD.After installing the machine i tried to mount the other three HDD but could'nt.
The error message iam getting is.....
'Not valid partitiion table'

Could anybody help me how to mount the HDD as user is having data in it i cannot format it.i tried with the command

#mount -t ext3 /dev/sdb /work1

- Well its just basically just like mounting an external usb hard drive to a linux machine.
- you can test it out first by mounting temporarily using the mount command as you have mentioned.
- but if you want it to be permanent and be automatically mounted every time the system is rebooted after wards; you will have to add an entry in the /etc/fstab

q1.) Does the new system detect the 3 additional hdds? what is the return result of the "fdisk -l"?

q1) Did the user say that the LVM spanned over all those three hard drives?
q2) what are the physical sizes of each of those three hds?
q3) how many partitions need to be mounted?
q4) what was the used space in each of those 3 disks?

If this is true then you would need to have all the HDs to be detected by the OS since the data stored on the LVM was allocated on all HDDs in the original setup. If they didn't use LVM and only normal partitions then it would have been easier to mount it again.

try your best to get the other 2 detected.
