I had Mozilla open, another prog crashed, I closed Mozilla and eventually had to hard reset the computer. When it came back up again, my bookmarks and cookies had vanished. There was no file system damage, so it was probably more an oversight in the way the Mozilla updates its files (maybe rewriting them on exit even if nothing changes?)

This is why RAID shouldn't be considered a "backup" solution. It will keep your comp running if a HD fails, but if an application does something stupid like overwrite a file the command is faithfully obeyed by the RAID controller!

Fortunartely, I had a recent backup so I was able to restore cookies.txt and bookmarks.html.
