YEAH... Hope someone can help... Our Mac Pro crashed, and upon reboot, both the internal raid as well as the external firewire drive that happened to be plugged into the machine at the time, are both 'locked' and we cannot unlock them. We've tried toggling the 'user and permission' choices from the 'custom' setting that they are now showing to read/write... and it just snaps back to 'custom'! Same if we try to change to just READ or just WRITE...etc...nothing... Just a gray icon of a LOCK under the icons of the drives, and a warning anytime I try to access them, saying I don't have permission to do so. I even unplugged the firewire drive and plugged it into another computer and it does the same thing! And I even made a new ADMIN and tried changing it with that, to no avail. Everytime I look at either of these drives, those 'users and permissions' toggles are back at 'custom' and they just won't relent! Oh, and I also flashed PRam and 'Repaired permissions' on the boot drive [yes, the boot drive is working fine] I need the media that is on these drive... a ton of video media on the internal raid, specifically... So I can't just repartition them from boot disk. Anyone have any ideas? Thanks!
