So last night I'm browsing the web when everything on my computer slows way down. My Hard drive was making the noise like it was fragmented constantly until I restarted the computer. After rebooting I logged into my profile (running Windows 7) and HDD is making the fragmented sound for almost half an hour while clicking on anything is impossible. There has been no sound coming from the HDD since. I run defragment even though it says it's just been ran and is currently at 0%. Now clicking on icons, links, anything really requires two to four clicks sometimes. I'm running this hard drive Link and an older WD 500GB harddrive that just contains media. Also ran Chkdisk which came back with 0 bad sectors.
