I have been running gentoo AMD-64 on my R3000Z from the get go (about two 
years now). About four months ago I began stumbling across filesystem 
problems.

In my case, I suspect hardware - which in fact is what I think might be 
happening to you.

First, what filesystem are you using? You mentioned Ubuntu so I'm going to 
guess ext3?

That doesn't really mean anything. I have used reiserfs on various laptops, 
servers, and workstations and never experienced corrupted filesystems.

A more pertinent question would be, "Have you used NTFS on this particular 
hardware?"

Anyway, a discussion of NTFS vs ext3 vs reiserfs vs whatever is probably 
off-topic, but I think it's safe to say that from a technology perspective 
they are all, on average, equally good.

A-ha! You might have hit on something there. It might very well be the 
controller. FWIW, a faster hard drive in a laptop is usually more "fragile", 
too. In otherwords, if you experience issues that you suspect are hardware 
related, swapping out for a slower drive is usually better.

Quite likely they are. Try keeping an eye on your system logs (as root, "tail 
-f /var/log/messages") in a console. See if you can re-create the filesystem 
weirdness (say popping in a CD and browse in a file browser) and check if any 
noise appears in the logs, in particular any errors about fileseek/access 
on /dev/hdc (for example). If you do, it's a good indication of h/w issues... 
(or of course, the CD might be damaged, but I guess that's a h/w issue, too). 
Try using other CDs. Try also doing a "find /" as root - this will list every 
single file on your harddrive and is also a quick-and-dirty way to see if any 
files are sitting on top of bad clusters/nodes/whatever.
