Make sure _not_ to make any changes though as you'll be thrusting yourself in the middle of a system upgrade (CTRL-C is your friend). If it's ufs1, it should definitely be converted to ufs2. There were some serious limitations in ufs1, in particular dealing with file size (2GB limit I believe) and features. Someone else on the list might be able to advise you or point you in the right direction if you want more details.. Also, you should be running softupdates. If not you're playing a risky game of russian roulette with your data, where if corrupted things can disappear between reboots if you didn't power down the machine properly (power down via ATX dead man power switch, power loss, etc). If all else fails and you're not running ufs1 on the disk, try upgrade your bios or firmware controller that the disk is operating on, and get back to us with more details. Cheers, -Garrett
