My computer (running Windows 7 Ultimate 64-bit) can no longer access my Western Digital Caviar "Black" 1 TB hard drive that's connected, but I suspect my data to still be in there, so I wonder what data recorvery tools people have used and recommend. This is one of the additional drives to my operating system C:\ drive. It has been formatted as NTFS and been working fine for several months until a week ago. Now it appears as the E drive on My Computer (as originally configured) but the volume label is now blank (I used to have that named as "Media"). When I double-click on it to enter the drive, I get the error message: "E:\ is not accessible. The parameter is incorrect." In Computer Management --> Storage --> Disk Management, the drive appears but it's File System is now indicated as RAW rather than NTFS. I have tried using Active Partition Recovery and that successfully lists my drive with the original label name ("Media") and as NTFS, and also lists the folders located at the root of the drive, which is why I suspect my data to still be in there and recoverable. However, when I use this tool to do a full scan of my disk, it freezes after scanning 35 MB. There are tools out there with varying reliability, so whch ones do people here recommend? (another tool I trired, I forget its name, was scanning my disk but prediced 43 days to go over the entire 1 TB, so that's out of the question!). I have been told to use a tool that can recover files onto a separate disk rather then try to repair the original disk and risk losing more of the original data. Any advice would be greatly appreciated. Thanks.
