SOLUTION: free data recovery tool by piriform called recuva was able to find all the data and is now moving each file into a directory of my choice. When using this program for data recovery from corrupt (or seeeeemingly corrupt) path, go into settings and make sure you check off "show files found in hidden system directories", "deep scan", "scan for non-deleted files" and "restore folder structure" under actions and recovery options respectively.

Hey, thanks for reading this.

I've got two identical 1tb WD elements ext drives. One belongs to my friend and i was doing diagnostics on it, the other is mine. i had them sitting on top of each other and switched the usb and power from his into mine without properly removing it from the OS first.

mine no longer is accessible. in chkdsk when i try to access my drive it says the directory is corrupted or unreadable. in disk management it sees it as healthy, active RAW partition. in testdisk it sees it as an NTFS partitioned drive.

I have tried replacing disk.sys and partmgr.sys driver files to no avail. I have tried uninstalling all USB controllers from device manager and restarting.

In seagate seatools the drive passed the self test but failed the short generic test.

The data on this drive is very valuable to me. Its been running for a week with no problems, I bought it to backup data on a seagate drive because I felt it was on its last legs. Since the WD seemed fine, i deleted most of the files from the seagate *facepalm*.

One other thing, drive has same issue when plugged into linux pc as well as other win 7 pc. Also, when i plugged my friends identical drive back in, it detected immediately with no issues.

I'm running out of ideas. Any help is greatly appreciated.

Thanks,

EDIT: in testdisk when i ask to see the files on the drive it shows two files without names and without sizes. it is odd to me that it sees the partition as ntfs while everything else sees it as raw. i know it was formatted as ntfs, i just don't understand why testdisk sees it properly and nothing else does.

EDIT2: i'm now running a WD diagnostic tool called lifeguard, so far it's not detecting any problems, the drive passed a 'simple test' as well as SMART but the extended test will take about 13 hours. I don't understand how this could happen; i realize HDD failure happens, but i was using the thing last night with no problems; I didn't even move it. I know the hardware is fine, if i format it everything will be fine, but it makes no sense. i guess i'll contact WD tomorrow if it passes their diagnostic tool.

EDIT3: WD diagnostic came up clean. so nothing's wrong with the drive except for the fact that life hates it (i.e. i've done everything i know how to do with it except format it). please....save......me.....changing the drive letter/path didn't work.
