I've been trying to make a clone of this HDD for a day now, but it's been horribly slow. Someone recommended doing a chkdsk on the drive and then rebooting, but chkdsk was going way too slow as well—it was scanning sectors one by one.

I downloaded HD Tune Pro, and immediately saw that the Raw Read Error Rate was over the limit at 44 (42 being the worst).

What should I do in this situation? Is it now impossible to clone the drive?

Don't run chkdsk and further stress a drive that might be failing! Create a Linux LiveCD/USB, download and run ddrescue to recover data to a separate physical drive. Be sure to read the manual first, and there are lots of tutorials on the net.

Depending on how much data is missing, if you're trying to clone your OS the copy may or may not work. You can try it, but I would recommend reinstalling your OS on the new drive, mounting the ddrescue image and simply copying your important data over.
