avoid disk crash while overclocking?

Sometimes when testing the limits of an overclocked system, the hard drive
may crash requiring the OS to be re-installed. But without the hard drive,
it is hard to run stress tests (most run under winXP). What do you do to
avoid having to re-install the OS over and over?

Run a real OS with a journaled file system (eg ext3 or ReiserFS) that
can clean up after itself after a crash.

Run a Linux LiveCD (Knoppix or Ubuntu). The CD can be booted, without
any hard drive connected. Once Linux is running, download the Linux version
of Prime95 from mersenne.org .

I've had four copies of the single threaded version running, as it is
easy to do that on Linux. (Just create four separate folders, with
a copy of the Prime95 download unzipped into each one. CD to the directory
in question, and start the program ./prime95 , setting the memory test limits
to 1/4 of the total free. Such a test setup would be suitable for
a quad core. I use a terminal window for each copy, so I can scroll back and
look at the test results. A fifth window can be used to display "top", to
see free memory and processor occupancy.)

This boot CD for Windows has prime95 on it. Boots real slow, though. A
pain to make one.

Well, no. Not sufficient (see NTFS). And on the other hand, the OS need be
reinstalled only very rarely, if ever, when a system hangs during
overclocking limits tests UNLESS THE BUS ON WHICH THE SYSTEM HARD DRIVE
CONTROLLER RESIDES IS OVERCLOCKED.

And to amplify on this you need a really old (2-3 years old) motherboard
that has the hard drive PCI bus overclock by default when overclocking the
FSB. In most cases the BIOS will default the PCI bus at 33MHZ even if your
FSB is overclocked.

A little less work is to use Stresslinux, has the programs already
installed and is small (100MB). Can be CD or USB flash booted, or put
on a small partition, if the partition gets hosed just dd a backup
copy over it.

It can also be customized so it will boot right into your preferred
test
