I bought a Maxtor hard drive about 2 years ago. Every once and a while, I hear a loud clicking noise. It never messes up my computer and it doesn't happen often, but I checked Maxtor's website just to make sure. They said that a loud clicking noise is normal because of the drive heads being parked. I have been making regular backups just in case, but I'm wondering if I should really hear any clicking noises at all and what that's really an indication of. I've had other Maxtor hard drives and I've never heard this clicking noise, so it has me concerned.
