Back in June, I wrote a column about the problems inherent with
the ubiquitous Windows rescue CDs that seem to come with most
name-brand PCs these days... This week, I thought it would be
useful to discuss some tools that can rescue a Linux system.
"Before dealing with the tools, let's consider the reasons for
rescuing a Linux system. You don't normally 'reload' Linux
software. Why? There is no reason to do so. As with the BSDs, Linux

as a disk drive, has failed.
"In a typical Windows rescue, the offending hardware is
replaced, the hard drive is wiped clean, and the software
reinstalled. The result is a perfectly usable system--but one
