not sure if it is damaged, but I do get smart problem raised during bios boot-up when I attached the drive directly to my m/b. After I reached my decktop, my computer does not show the drive at all. however, if I connected the hard drive via external hard drive dock, I can get Win to recognized the drive. Once Win recognized it, it keep telling to format the partition. should I go ahead and format the partition again,and use the file recovery program to recover all my files. I don't know if this is pertinent,but all this occurred when my bios switch the boot sequence, normally, the first boot device would be my hard drive containing the O/S, however somehow, bios switch to this problem hard drive as the first boot device. Once, I noticed what was happening, I set the boot device back to the proper place.
