There at one time was a warning about using the disk cache on older, pre
XP/2K systems that really referred to older computers that on
shutdown/power failure might not write the cache to disk, leading to
file corruption. Write cacheing is not set by default on any HD in XP,
I believe, since it is a technology is not robustly safe and that can
still result in file corruption on shutdown/power failure on a slow disk
that does not communicate well with the OS.
