Good to see it's working ok now. You should be able to repartition it
with Ghost now too. As I've used it on RH7.3, 8.0 & 9 without problems.
(And that's also the whole point of being able to use ghost to upgrade
to a larger HDD when needed. As I keep a copy of it on a bootable CD-R.)

The only thing I have encountered with Ghost, was the booting problem
from time to time (Which can be corrected by what I mentioned in my
first post. And that the older versions 5->7 wouldn't handle the Linux
Ext3 system too well, where as you found out that version 8 does it
nicely.
