Hard drive errors are possible, but you usually don't see
them as networking issues. The easiest way to rule out
this problem is to boot from a live CD / DVD / USB, either
using FreeBSD or Linux.

You could even keep one of those HDDs as a "test system"
for further use.

I just wanted to mention it as one of the wisdoms I learned
at university. Another gem from the same professor was this:
"Programming is not fixing your code until the compiler stops
throwing error messages." But if it helps you achieving a
goal, why not? ;-)
In no way this quote was intended to belittle you. It just
perfectly fit the "I randomly changed a few numbers in the
IP address and it still didn't work" comment. When I did
graphics programming many years ago, you sometimes really
had to minimally adjust numbers in parameters to see if the
result matched your expectations, simply because you could
not accurately predict how certain values would affect the
result of the rendering process. :-)

So you always have a good reference system

Yes - knowing networking basics and tools is very important
and usually helpful when running into issues. My suggestion
always is to start at the lowest possible level and diagnose
as much as possible, so you know _for sure_ with what you
are dealing at a given moment. Nothing is worse than guesswork
