I had a similar experience. All I can say is windows 98
and ME seem to have it out for Linux drives running late
2.3.x and 2.4.0 test and release. I had windows completely
fry my Linux drive and I lost everything. I had some old
backups and was able to restore at least the majority of
older stuff.
Sorry and good luck.
