Hard crashes

["Russell Hires" <rhires@earthlink.net>]

Hello all,

I've got a problem that's been perplexing me for a while. I've got a
non-apple scsi hard drive in my Quadra 700. Whenever I try to do some
things, such as copy a large file from one place to another, the disk
_crashes_ . No response what-so-ever from Linux. I can't switch consoles,
the cursor doesn't flash -- nothing! I have a Quantum  something-or-other,
which is a 500 MB or so disk, with 50 MB swap, 50 MB mac and the other 400
MB devoted to Linux as one /root partition. 

I'm pretty sure it's the disk, since I've used several kernels -- two
precompiled (one was 2.2.10 from the latest disk-images), one compiled from
the mac cvs 2.2.14 and even the latest one with the new disk driver. 

Does this mean that I need to do a bad-block scan on the install? Or can I
just do something with fsck? fsck already has done its thing since the
machine has crashed several times and "fixed" whatever it thought was
wrong...

Thanks for any help...

Russell
