My computer was running fine until a couple of days ago, when the hard drive started making a clicking sound, and the hard drive access light started coming on excessively. I had just received some large files by email, maybe 10-15 mb for each file - maybe 12 of them total. I know the files were virus free, and were just very large. I moved the files to a separate folder, and then copied the folder to a separate hard drive that I use for data archival, then deleted the original folder to make room on my Window's drive. My hard drive had been a bit low on space, so I suspected (hoped) that the clicking sound had to do with resources, and wasn't a lost drive. I finally got the system to successfully reboot, which took several failed attempts. Once it did reboot, I was able to defrag the drive. Everything was looking great at first, for the better part of a day...no more clicking...until I left the room for a few minutes, and Zone Alarm did an update. It was locked up when I returned, with the hard drive light on steadily. My main question has to do with whether the fragmentation of the hard drive could be the problem. The report showed that the drive was badly in need of defragging, which was done. The Pagefile framentation was not corrected by the defrag, however. Here's the data: Pagefile fragmentation Pagefile size = 600 MB Total Fragments = 2,758 Any suggestions on how to proceed with this? I've already bought a new drive, and can install it when needed. If the current drive can be saved, though, I'd certainly rather do that. Thanks in advance for the help!
