Hi

Usually the best advice is indeed to boot from Live CD. DO NOT TRY AND
BOOT FROM THE DISK. Booting from the disk may increase your problems.
In the Live CD you should install ddrescue
(http://www.gnu.org/software/ddrescue/ddrescue.html) and use that to
copy the ENTIRE DRIVE to a new disk.

ddrescue has some advantages above dd.
