    I have 3 1TB WD green hard drives in a 4 bay Probox. I was just doing some editing and the power went out but my PSU's battery just recently died so everything shut off but it was only for about 1 second. I reboot my mac to find my hard drive that was named External 2 now named External 1 and has no files that were in it and only the folders and names that were on my external 1.

    I have no idea what happened but apparently it somehow copied just the folders of my first external and deleted 800gb of video. I went to verify in the disk utility and it said that it needed to be repaired immediately. I did that and it didn't do anything that i have noticed but it says the drive is completely fine.

    Any ideas on what has happened? or if my data would still be on the hard drive somewhere?:confused:

    Data recovery is a complex and expensive process. Your data may still be on the drive, before you resort to expensive third party recovery companies try:

    one of the utilities in the list here...I can't vouch for them, but it's worth a shot:

    Prosoft Engineering's Data Rescue works well (I haven't used v3 shown in the link below but I have used a previous version and it worked well):


    You might want to give Disk Warrior a try. From what I've read, some users have used it to rebuild their entire disk directories (that's what it does) and brought back data they thought was lost. I have it and have only used it in a preventative capacity. DW is not "data recovery" software per se (not in the same way as Data Rescue), but if your data only appears to be missing due to a directory error from the power loss then DW can rebuild the file directory and bring it all back. Give this a read, it may be just what you're looking for:

    If you have access to an IBM PC, get Spinrite and put the HDD in the PC and run that program. It's a great HDD maintenance and recovery software tool.

    I use it all the time on my computers for optimal performance and use it to fix many others HDD problems.

    Only 2 utilities you need are DiskWarrior and DataRescue. The rest are superfluous unless you REALLY like defragging and gaining 0.0000001% performance increase as a result of 5 hours work. I have no experience with Sandbox's suggestion as I have never needed anything else.

    I concur! And I have never needed anything else besides DiskWarrior and Prosoft's Drive Genius. I don't own Data Rescue personally - the one I used was at work.

    Pootarts: In all seriousness, get DiskWarrior. I strongly suspect that it will clear that issue right up and bring back your files safe and sound, like they were never gone. But, the great thing about DW is that you can preview the rebuild before you actually do it, so if you don't see your files in the preview of the rebuild, then you can cancel before DW does anything to your disk. So there's nothing to lose. Just gotta buy the software.

    Those are the only two I've ever found to be useful. Outside of those two I can't think of anything useful other than expensive extraction. The only exception I can think of is self enclosed oem external drives like LaCies. Sometimes the failure is something other than the drive itself like a burnt out bridgeport, so assuming a non Raid/single disk version, you can disassemble it and recover the raw drive. Overall most of the applications that claim to retrieve your data aren't very good.
