Im a Graphic Design student that has just graduated after a 3 year course. I save all my files on an external HD to conserve space, its a LaCie drive that I've used for the duration and it has just recently crashed severely. It was a USB 320GB LaCie Prosche design, been regularly storing not only my school files but also backing up my Mac Pro via Time Machine. For the last month or so I've been getting errors that Time Machine has been unable to backup due to my HD being filled. I ignore them as the work I've been doing recently hasn't been important. But today I've installed new software and completed important work so I wanted to make sure it backed up. I get the Error "Disk cannot be Read" with an explanation mark on a red triangle with 3 options, Initialize, Ignore, Eject. Initialize brings up Disk Utlity which fails instantly on Verify Disk and Repair Disk with the error "Filesystem verify repair failed". Since the External Enclosure eventually made the drive unreadable resulting it in me not even receiving the error message anymore I thought it was the problem. So I take apart the enclosure and install the HD into my Mac Pro directly. The error once again appears so I know the drive is being read, and that same errors occur when it was being read from the enclosure. I run Disk Warrior Rebuild and it runs, and runs, and runs for about 2-3 hours usually. Getting to the same spot everytime, just at the end of Step 6, it sometimes happens right away, but sometimes happens when the bar is complete and looks like it is transitioning to the next Step. The error then comes up saying "Lack of Memory" saying it cant rebuild the drive. My computer is a 2.8GHZ Dual Quad Xeon with 6GB of Ram, does disk warrior require even more power to rebuild the drive? Whats happening here? I run the utility when there is literally nothing else running to consume RAM, so it is using at least 4GB and asking for more. What do I do? I've tried everything, even hooking up my MBP via firewire and trying to run rebuild. It gets past step 6 but the same error happens halfway through step 7. The Disc won't let me boot from it as it appears to have a scratch on the bottom, and fails on a CD Target Disk Restart. Any ideas or suggestions would help, I need the data off this drive as it is my last 3 years of schooling, and half of the data is impossible to get again! Please Help!!
