Over the past few years I've bought maybe a half-dozen "Y-Connectors" that allow one to daisy-chain additional hard drive power connectors off of the original four or so that come on a typical power supply wire harness.
Over the last few weeks I noticed some unusual "click" noises coming from my PC case. Things seemed to work okay, but then I began to have problems with my DVD burner "hanging" half-way through a burn.
Eventually I found that I could get the click noise by gently flexing some of the power connectors inside the box. Conclusion: one of the Y-connector assemblies was occasionally intermittent, making a disk drive and/or the burner drop off-line for a fraction of a second. The clicking sound was the sound of the heads parking and then restarting inside one of the drives. Funny thing is that I never lost any data on the drive. Just lucky, I guess.
