Hard drive disappeared

I was copying about 350 gigs from a hard drive in my computer to a larger drive in a sata dock attached via usb. Everything was going fine. Then the transfer was interrupted with an error message which unfortunately I do not remember. The gist of the message was that something could not be copied. "skip" was one of the options. I checked skip and immediately the transfer abruptly ended and the hard drive. "G" in my computer from which I was copying disappeared. It disappeared from "Computer" and Windows Explorer and from the HDD list on computer management / storage in the control panel.

I tried system restore and from a restore point and the image the system created, neither of which worked. The failed restore returned this error message System restore failed to replace the file (C:Windows) with it's original copy from the restore point. An unspecified error occurred during system restore, (0x8007/a90).

My machine is custom built. The operating system is Windows 7 Ultimate 64 bit. Other than the missing HDD everything else seems normal.

What can I do? There was a lot of data on that disk which I need.
