I have a Western Digital WD5000BEVT 500GB hard drive which I connect to my Unibody MacBook Pro to store files. After not using the hard drive for a few days (during which time it took a small fall) I am unable to use the drive. When I plug the drive into my Mac (via either USB 2.0 or FireWire) I receive a message saying "The disk you inserted was not readable by this computer.", but the computer is readable by Disk Utility. When I open Disk Utility it shows the drive as a 2.2 TB drive (which is odd) and that the drive is no formatted. When I try to either "Erase" the drive of "Partition" the drive, I get an error message saying "Partition failed. Partition failed with the error. POSIX reports: The operation couldn't be completed. Cannot allocate memory" Does anyone have any ideas (preferably free) as to how I can recover the data off of my hard drive? Any help would be greatly appreciated. Thanks in advance.
