You can disable write caching on your disks (most even honour it :) however a lot of people choke at the performance hit.. One big problem is that high capacity disks use track writing - if you modify a single sector the disk re-writes the whole track. If the power fails during the track write then you lose potentially completely unrelated data. This affects all file systems equally though. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
