So I have read some other posts on here to get an idea of what i should do but i just want to verify my problem and the solution. I have a 500gb caviar black edition and i have noticed more and more its getting slower with boot up times and windows 7 will take forever to fully load. It will freeze quite often. I tried reformatting it and at first everything seems fine but after a few days it will start showing problems again. So i began running tests. The Data Lifeguard test seemed pretty good so tried it and after about 1 or so it fails. I tried it a bunch of times. Restarted the PC and tried again and still. I tried doing it from a bootable disc and i still get the same problem. I ran another test with it and gets past a few sectors very slowly and then freezes on one sector and doesnt continue. Im ready to RMA this thing! I just want to know if there are any other things i can do for it. Any tips would be great thanks! Let me know if you need more information.
