I am using ReiserFS for years now and the only near data loss situation I have experienced was my lilo.message file becoming unreadable due to a bug in the new unpack tail ioctl(). But even then Hans' team provided me with excellent support and I regained access to this file using the 2.3 linux development kernel where that bug had already been fixed. I would however never trust my important data to any file system nor any disk drive without having a backup. Additionally you should not blame the file system for your broken hardware especially when your disk drive lies about data having been written when it is lost from the write back cache on power failure.
