I am trying to rescue the data off a failing external hard disk, but I am running into a number of problems.
The file transfer will consistently freeze up on specific files, and the program being used to transfer the files enters the "not responding" phase, and the program turns white. When attempting to end the task of the frozen program, Task Manager doesn't throw any errors (such as "access denied"), but the program remains in the task list. This has been tried with multiple copy programs, including Windows copy, TeraCopy, Free File Sync, and Roadkil Unstoppable Copier. The queue length of the hard disk in Resource Manager is stuck at 1, however no disk activity occurs.
However, the moment the failing hard disk is unplugged from the system, the unresponsive programs then begin to respond again, and any tasks stuck in the Task Manager immediately end.
What is happening here, and is there a way to rescue the data from the failing drive?
If it matters, I am copying files off the USB3 ports of an Intel NUC5i3RYH, from a WD 1TB My Passport Essential to a WD 3TB My Passport Ultra.
