Check to see if your drive is a "SMART" drive.
<http://en.wikipedia.org/wiki/S.M.A.R.T.#Self-tests> A SMART drive is
capable of running self-tests to analyze its own performance. But its
self-testing should not be so intrusive as to interfere with real work.
The run times you report seem excessive for the amount of data involved.
It's possible your hard drive is undergoing soft failures... getting
read errors which are ultimately recoverable after one or more retries.
That's the sort of thing that SMART should be able to detect.
However, if any of these drives are not internal but are connected via
USB 2.0 that may explain your speed problem. USB 2.0 is truly slow.

Just a cautionary note.
I have been suspicious for a while of hard drive activity that I could see no
call for, so in addition to having Avast antivirus running I installed
Malwarebytes to check for the sort of malware they specialise in.
It took more than a day to check my C drive ( which is small) and THREE AND A
HALF days to check my main data disk which has less than 200,000 files and has
just 168 gb used.
Just now it started up again despite me (thinking had deferred the next scan
for about a month) trying to avoid those excesses. In doing so it greatly
paralysed the machine.
I have just uninstalled it !! I can reinstall it if I see a need.
