I've had a Fantom external for quite a while now (2-3yrs) and it has always been a bit noisy when accessing data (very fast random clicking noises) which I have always just taken for granted and dismissed as "normal" hard drive noises. However, it seems like these noises are lasting longer and coming on when data is not being accessed. They are the exact same noises as data accessing, and do NOT sound like the head scraping (the drive functions perfectly fine). In particular, when I first turn on the drive (already plugged in to my comp) it has always done the data access thing until I close the window that pops up in Windows asking me what I want to do with the drive. Now, the noise will persist for at least another 30sec. Also, sometimes I'll leave my computer and HD on and leave for a while, and when I come back the HD will be clicking vigorously like it is being accessed. After I start using the comp again it will stop. It almost seems like Windows is trying to automatically defrag the drive or index the files or something, but I know I have scheduled defrag turned off and I'm not sure about anything else. All this thinking about the possibility of my drive failing has me very worried as I have 931GB of stuff on there including every picture I have ever taken (I'm a photog). Could this be my drive failing or is it Windows accessing the drive behind my back? Or is it just normal and I didn't notice it before? Thanks for your help.
