I just bought a seagate hard drive (ST380011A) and right away it’s started making a chirping sound. It happens whenever the drive spins up quickly from a stop, such as coming out of standby mode. It’s a single, half-second squeal (loud enough to be heard over case fans and ambient office noise), then it’s quiet again. The only other hard drives I’ve had were another seagate that hasn’t made a sound in the 2 years I’ve had it, and a 4gig WD from my old computer that sounded like a tractor most of the time. So I don’t know if I just got lucky with first seagate and that kind of noise is normal, or if it means a mechanical flaw that will lead to an early death. I ran the disk checking program from seagate and that was fine, and there are no other problems. So what I’d like is some feedback on what (noise-wise) is normal, and what is trouble. Thanks.
