I am editing an extensive project on FCP7 on a 2011 iMac with 3.4GHz i7 and 8GB RAM running OSX Lion 10.7.5. I am using two G-Raid Lacie external drives (4TB each) that are connected via firewire.

 

Editing has been smooth for many months until...today while I was editing, I got a popup saying my hard drive had crashed. I also experienced some slow playback/freezes in FCP timelines before the hard drive crash. I don't remember the exact text in the popup, but something like "unable to repair disk" or something serious! Indeed, one of the hard drives no longer appeared in the Finder. I quickly saved everything, then shut down the computer and turned off the hard drives. After booting up again, both hard drives successfully appeared and a quick search through the hard drive revealed all contents were still there, thank god. The FCP project file opened up too. However, when I tried to open the main sequences in the project, I got a popup saying "No movie in file" and then "out of memory." I tried troubleshooting reading other tips and deleted all the render files, but that did not work. I tried opening the sequences with the crashed hard drive turned off, and the sequence then did open. I don't know whether I just have some corrupted files on the drive that need to be deleted, or if something with the entire drive is corrupted. My next step is to purchase another drive and transfer files, then test one-by-one to see if/where the corrupted file is located. Any other solutions or suggestions would be greatly appreciated! Thank you in advance.

    Corrupted QuickTime movies are very difficult to recover. You may have some luck with Digital Rebellion Pro Maintenance Tools:

     

    http://www.digitalrebellion.com/promaintenance/

     

    which contain Corrupt Clip Finder and to help track down corrupt clips and Media Salvage to try and recover the files from the corrupted media.

     

    Don't just by one disk drive, by enough so you can keep complete back up copies of all your media. This is/should be SOP for working on large or consequential projects.

    I did keep the original video files on separate hard drives with additional backups. The files were then converted to ProRes, which are kept on these two editing hard drives. I probably should keep backups of these editing drives, but if need be, I can go back to the original files and convert back to ProRes. It would be really cool to fix whatever is wrong with this drive though! Thanks for the tip on the digitialrebellion site.
