Ubuntu Ibex on single SATA Seagate disk, ext3

[Stephen Samuel]

One question I have  is: why is the system repeatedly rebooting?? The answer
to that question may
point to something about why you're losing data.

I tend to find that, with Linux (and unlike some other OSs
[cough]WIndows[cough]), repeated
crashes tend to point to some kind of hardware error, and -- where there's a
software source to
the crashes -- there are people who are genuinely interested in(and capable
of) resolving the problem.
