I am using an HP Pavilion dv6 running Windows 10.
I have retrieved a 500GB Western Digital Scorpio Blue HDD from another Windows laptop. This is the main hard drive with the OS installed.
When still in that laptop, the computer won't boot up at all. It brings up the very first screen for about five seconds, and then the entire laptop powers down, then repeats infinitely.
I am using a Apricorn brand USB to SATA adapter to read the HD externally. The adapter works and is working properly, having tested with another drive.
When I plug the adapter in, the drive spins up almost immediately a "G" partition appears in "Devices and Drives" on my laptop. This partition is labeled "System Reserved" and is 100MB in size with no data on it.
A minute or so later an "H" partition appears, but that's the extent of it. A green loading bar starts at the top, fills, and just sits there loading. If I try to click on the H drive to open it, a spinning wheel appears and it seems to try but nothing happens. If I right click on the drive and click properties, nothing comes up.
If I try to open Disk Management while the disk is plugged in, the window opens but it just hangs at "Loading Virtual Disc" but won't open up.
I attempted to run ChkDsk from the dos prompt. When I type CHKDSK G: it says it finds no problems. When I type CHKDSK H: it just hangs there (surprise surprise.)
At this point I don't know what to do and I'm in a panic to salvage the data from this drive. Any help is deeply appreciated.
