Try the current rawhide kernel --- it includes IDE patches which force a cache flush on powerdown (some distributions have initscripts hacks to force this already.) Those patches are in the -ac kernels too, and we hope to see them in mainline 2.4.20. Windows? I have no idea. Cache-flush workarounds for powerdown won't save you if you let the battery run dry, of course. Cheers, Stephen
