I bought a 60GXP last week (60GB), and yesterday it developed a 'click' when powered on and it failed to boot. The same thing just happened again a few minutes ago. Luckily it booted up after a reset but I don't think I'll take my chances. This is my first IBM (had two Maxtors, a WD, a Seagate, and a Quantum) and this is the first time I've had such a thing happen to me. Neither S.M.A.R.T. or the IBM Drive Fitness Test (that I ran yesterday) came up with anything.
