[clug-talk] Thorough disk check/stress test utilities?

I have been experiencing some odd behaviours lately in an otherwise very
stable desktop box (mostly hangs, some odd clunks now and again).
At first I thought it was RAM since I tried having an upgrade done in rather
dry, cold weather. However, I ran memtest86 for a few hours afterwords with
The clunking I thought was a disk spinning up from power saving mode (since I
semi-recently added -S240 to hdparm settings). But lately they seem to be
happening inside 20 min. of last disk activity.
Also, I did do a standard fsck after a couple nasty hangs in row (for both
ext3 and reiserfs) and reiserfsck found a few corruptions and fixed them.
Naturally, I didn't bother to note which disk or partition, since I still
thought at that point it was a byproduct of a RAM-induced hang. :-P
So I'm starting to strongly suspect one particular drive (I have 3 x 10GB IDE
drives). I'm backing up all my data right now.
I've got 1 x FAT32 shared partition, 2 x reiserfs partitions and 2 x swap
partitions. (Yes, 2 swap... I had extra space to kill and didn't need a tiny
128MB partition for data. Swap priorities are set accordingly :-P).
I want my system back to its stable old self. If that means losing 1/3 of my
storage, then so be it. I just don't want to do it on a hunch. So after
backing up my data, what can I do to:
1) Thoroughly check all file systems, including swap.
-note: I tried a thorough GUI Scandisk from Win98 which resulted in a hang.
2) Stress test the disk to see if I can induce/reproduce a problem?
-note: the disk activity LED stays solid red on a hang w/ no disk activity.
Sorry for the verbose post. I'm a little caught up in it at the moment. It
seems I haven't done backups for awhile, so I've been a little nervous. :-P
Thanks in advance,
