So I installed my new hard drive 1tb WD to my older rig when I came back to my home country. Had alot of trouble installing it (because there was another hard drive with Windows In use) and somehow it's working now like I want i managed to get it discovered by Windows and all. HOWEVER, ITS EXTREMELY SLOWW. my specs are fine I've got AMD fx 8350 and 16gb ram and my other hard drive and the external hard drive are working perfectly but this one is terribly slow (the other hard drive is also 1 tb WD) the speed is really horrible like transferring 10gb estimates 11 hours. What should I do?
