It looks like I had a dodgy disk which was being tickled by the time = machine backup (eg dodgy sector where the backup was located) so I have = been chasing a ghost :) However, thanks to everyone for your helpful suggestions! I still haven't tried iSCSI, given I can't do a bare metal restore from = it it doesn't seem worth it (also I don't have the time..) -- 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
