I was using SuperDuper to back all my files (about 98GB) onto a external 320GB firewire harddisk. There was 150GB very important files ( High Definition video footage for clients) on the firewire disk, obviously I didn't want to erase anything so in the backup option, I didn't choose "Erase 320GB... from Macintosh HD", but chose "Smart update 320GB... from Macintosh HD", because it's said "smart update will copy and erase what's needed to make 320GB.. identical to your selections from Macintosh HD. The result will mimic 'Erase, then copy', but will typically take a fration of the time." So there was enough space for making a backup of the 98GB files that were needed to backup. And there was no warning at all. After the backup finishes, I found all my important files are gone. This is fatal... Now, how likely is it to recover the 150GB files that was on the firewire disk? Do you have any suggestions?? Data Rescue II?
