Secondary Internal Hard Drive suddenly turned RAW.

Hi there, I'm having some frightening hard drive trouble, and I'm wondering if some wise person can help me out.

I have a new, empty 1TB drive that I planned to copy all my 500GB drive's data onto, once I ran out of space. A couple days ago I noticed my 500GB drive (my D: drive) was missing from windows explorer, but I restarted my PC and it returned, functioning normally.

I figured now was the time to copy the drive and replace it with the 1TB, but when I plugged in the new drive and rebooted the system, my D: drive came up as "Local Disk D:" whereas it's usually "Data D:". I checked Disk Management and it's file system is set to RAW, and it's status is Healthy (At Risk).

When I try to access the drive I get a cyclic redundancy check error. Turning to Google for help I tried using iCare Data Recovery and EASEUS Data Recovery but both programs seemed to slow down tremendously after finding around 240 files, and the estimated time continued to rise to about 500 hours, while no new files were being found.

There's lots of valuable and irreplaceable data on the drive, and I need to recover as much of it as possible.

How do I recover my data and or repair the file system, which do I do first? Which programs do I use?

EASEUS recovery seems to just slow down to this point after several hours.
My X drive in that image is the new 1TB drive I installed, and the missing drive is my G: drive which I've disconnected due to this maintenance.



I would be forever grateful if someone could help, I have no where to turn, and I'm freaking out.
