Recovery very very slow

Hi,

I have a WD 1 TB hard disk. It contains upto 950GB data. Unfortunately, sometime ago, my hard disk no longer showed any files. It will take a long time to open and finally will end up being shown as a RAW DISK. I tried many other softwares like TestDisk, but none was able to show my files. Finally, I used Recuva v1.49 and I went to Options and enabled the search for undeleted files and after 1 hour scan(3 phases), it detects all my files.

I basically would like to recover all my files. I purchased another 1 TB hard disk to do it. But, the recovery is failing for very few cases with "Cyclic Redundancy error". For the ones it completes successfully, it takes a really really long time. It has been running for more than 12 hours and it has recovered only some 5 GB till now. All are movie files.

Is there any way to speed up the process? Any other clues/suggestions?
