How do I back up an internal drive from install Disk Utility??

[pensivecrow]

I have my internal drive on a dual 2.5 G5 running Tiger that is giving me this error after running the Disk Utility from the install DVD:

Invalid node structure
The volume Macintosh HD needs to be repaired

Error: The underlying task reported failure on exit

It also said that it was unrepairable. My question is, can I back up this drive from the Install DVD Disk Utility if I am unable to boot from the hard disk itself? I have a feeling I will have to reformat the disk and would like to keep the data on it if at all possible before completely wiping it.

Solutions would be awesome. Advise will be great too!

Thanks!!

You'd actually want to Clone the drive, but you should first try using Disk Utility on the OS X DVD (when you restart from the Disc) and try to repair the disk, since you can fix it while running any apps from it.

I already tried repairing from that Disk Utility from the start-up DVD. No success. Like I said in the original post, it gave a message saying it was unrepairable. I just want to save the data. The drive is dying. It's given me issues before.

Can I clone it from the DVD disc somehow using an external drive?

Thanks.
