Slow USB 3.0 transfer rate

[Qreatix]

Hello, I have a question:

I have a Dell Inspiron 17R, 8 GB RAM, 1 TB, Windows 8.1. When I first for the laptop (1 year ago) I had to transfer all my files from a external hard drive to my laptop, it topped at 30 MB/ps... Right now, when I try to move files from my laptop to the hard drive or vice versa, it gives me 3MB/ps... I have no idea why it suddenly lost 90% of transfer speed, do I need to update my driver or something? Or is it something else?

Also please note that my laptop crashed about half a year ago, and I recovered it with a recovery disc. I'm not sure if this has something to do with it, but I thought i'd better specify it.

I hope someone knows a solution, thanks in advance!

How full is the harddrive?
keep in mind that harddrives slow down as data on the inner tracks cannot be transferred (in or out) as fast as the outter tracks.
