HDD1: Loud squeak when operating. Intermittent, random. Not a rotation problem (not consistant). HDD2: Doesn't appear on system. Swap the PCB from HDD1 to HDD2. HDD 2 makes slight squeak noises, but is in general loud. (i.e. not the same squeak noises) HDD1 behaves the same as HDD2 did before the swap. HDD1 also still squeaks when on. So. any ideas on wether I got 2 bad drives together both very loud, and one bad PCB? I set the squeaky one to zero-out and it remained a completely random squeak pattern. Installing windows xp through VMWARE fusion on HDD2 It remains yet still a completely random noise pattern. Both are brand new 80gb IDE seagates. Both drives store data when using hdd1's pcb.
