I know this is probably a hard question I'm asking, but I am still wondering if this is hard drive related at all?

Originally when I went to reinstall Mac OS 9.2.1 (using the OS 9 CD), it had trouble reinstalling for some reason, and I ended up having to drag all the system folders into the trash and then trying to reinstall.. could that have been a problem that might have left bits and pieces behind of whatever was plaguing the machine?

Anyway, I just want to be able to semi-use the machine with the specs it has rather than upgrading it, I like Classic and I'd like to keep it with OS 9 if possible.

Thanks.
