DAMAGED FILES after FAILED transfer. HELP!!

[mattg1217]

Hello All! I'm running Windows 7 64-bit Professional.

I was attempting to transfer files from one internal HD (WD 4TB) to another internal drive as a backup (same exact type HD). Neither of these internal drives are the OS drive. In the middle of transferring files my power went out multiple times. Then on startup I started getting the message "check disk for consistentcy" referring to the original HD I was attempting to transfer from. The check disk would run and never finish. It would simply go to a black screen and freeze. After multiple failures I gave up. I never could get the PC to boot up.

I then removed the original 4TB HD and booted up the PC. Everything worked. I connected the 4TB drive via usb with an external housing. It read it fine but the media files I was attempting to transfer would not open in any program/device. They have the correct file size and are all still present on the HD, but seem to be damaged in some way. So I then ran a "chkdsk" and it completed successfully within a few days. But it did not repair the files. These are all media files, from .wav audio, .mts video files, to .mov video files.

This is a years worth of work. I have talked to a professional recovery company and they seem to think the files can be repaired. I want to exhaust every effort possible before I fork out thousands of dollars on this, which I am more than willing to do.

I have tried "restoring previous versions" of the files but there are no previous versions to restore.

Any suggestions?!?!?!? I'm desperate!!!

Hello and welcome Matt mate here are recovery softwares - I don't know if you have used any but Recuvva is very good and there are more Best Free Data Recovery and File Un-delete Utility if they are physically damaged then perhaps they might not be recoverable

One way of getting data from a drive is to us my little ditty
BOOTABLE UBUNTU
Make a bootable Ubuntu disk http://www.ubuntu.com/download
Set the BIOS to boot from the optical when the machine boots it will show you a screen with TRY or INSTALL > select TRY not INSTALL
When it is finished - it takes very little time you will get a screen like in the pic .
Open the drive you want > User and dig down until you get to the data / settings you may be able to copy / paste the material you want to an external source or other installed drive doing this.
I am not sure if it will but I have recovered tons of data etc using this method both on "dead" or just plain drives that you cannot get data from using Windows.
There is also the Linux Mint MATE way too but I find the Ubuntu is reasonably easy to use you will either have to keep the drive in the machine or hook it up to a different machine using the USN to SATA adaptor in the pic
