I just bought an old Pismo, but the HD is making a lot of noise, not only when it's reading or writing, but all the time. Is this normal on older harddrives? I've got a rev. C PB 12" that I never hear anything from, and a LaCie which I can hear sometimes, but is not like the Pismo. I've done some googling, and the IBM-DJSA-220 HD in the Pismo, is from what I understand not the most quiet, but still. Mine's loud. I took a HD test with TechTool Pro, and the S.M.A.R.T.-test showed an error with "Load/Unload Cycle Count". Everything else was OK according to the test. Can anyone give me a hint on what's wrong? If anything is wrong... I would appriciate it very much.
