Getting Data off old hard drive

artemis · 10-29-2002, 04:48 AM

I recently got myself a new Maxtor hard drive to install in my PC. In the process, I decided to disconnect my old hard drive while I installed Red Hat 8.0 in my new drive.

Everything worked as planned and RH 8.0 works smoothly. Now I need to get some old but important data off my old hard drive. I connected it as a slave drive in my PC (it has RH 7.2 on it) but unfortunately when the PC boots up, it keeps getting confused with mount points and seems to try reading from the slave drive as well as my new (master) drive. Then it gets its knickers in a twist and gets stuck at the System Logger startup point..... requiring a restart.

How do I connect my old hard drive as a slave to my new system and get the data off? Help - I'm a newbie to this, I've never done anything like this before.

And I thought it would be straightforward!

Is the old disc jumpered as slave?

May be giving the system the correct partition of the root fs at boot time via the bootloader helps.

Yes the old disk is jumpered as a slave.

Quote:

My NEW /etc/fstab reads like thus:
LABEL=/ / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

In the boot-up process, does the OS read the info contained in grub.conf (I am using the GRUB bootloader) before loading and mounting the filesystems? I think it is getting confused because the fstab on the OLD drive is also similar to the above.... and it is trying to mount the old drive too and failing. To prevent this confusion, would editing the fstab entries in the old drive as well as its own grub.conf help ? - I can access the old drive again by re-jumpering it as master and booting from it.

Try changing the entries for / and /boot to the correct partitions. See how your SWAP has a specific and given partition to use, but your / and /boot mountpoints are simply directed to / and /boot...?

Try it as this:

Code:

/dev/hdaX / ext3 defaults 1 1
/dev/hdaX /boot ext3 defaults 1 2
none /dev/pts devpts gid=5,mode=620 0 0
none /proc proc defaults 0 0
none /dev/shm tmpfs defaults 0 0
/dev/hda3 swap swap defaults 0 0
/dev/cdrom /mnt/cdrom iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0 /mnt/floppy auto noauto,owner,kudzu 0 0

Obviously replacing the Xs for the correct partition numbers.

Hi Grant,
I tried doing what you suggested, replacing the nameless LABEL=\ entries with /dev/hda1 and /dev/hda2 respectively. I also had to change my grub.conf file accordingly to reflect the changes. However, when I booted this up, I got a kernel panic.
I ended up having to boot into rescue mode and changing my fstab and grub.conf files back to the originals before the machine would boot properly.

Any other ideas?

Try changing BOTH drive's jumpers to cable select. Works flawlessly for me
