I have also found problems with X and heavy IO. I should upgrade
to a newer X, and see if it persists. I suspect it's an X issue,
anyway.

Ouch. What do you mean, "fails it's self test"?
Can you run e2fsck on it? Anyway, copying *from* a partition
in parted shouldn't do any damage...
Was the partition mounted? Maybe there are cache issues...

I would use tar or some backup program.

Perhaps partimage.sourceforge.net is what you want...
I don't think it does partition tables / MBR though.
(you can do that with dd, though:
# dd if=/dev/hda of=mbr.backup bs=512 count=1
)
If you want to backup "then entire disk", you can use dd
to copy. Eg: if you have a spare hard disk:
# dd if=/dev/hda of=/dev/hdb bs=4M
(bs=4M means "copy 4Mb at a time")
If you copy all the partitions on a disk to another disk
with Parted, it won't be bootable. However, it is easy
to make it bootable, by booting off a floppy (say, the
parted boot floppy, or your distro install CD), and doing:
# chroot /dev/hda[INSERT-ROOT-DEV-NUM] /sbin/lilo
