Wow that surprises me that apple would use something that isnt proprietary(sp?). but just do the reformat stuff with the HD and see if that works. If not I could turn it into the first 120gig Ipod 
So just a good SMACK will do it? i have a 30 gig ipod bran new and its clicking it started last night
I smacked mine, and it started working again…
then it died again a week later…smacked it once more, it started working…
then I downloaded “RockBox”, an open-source Ipod Firmware…and I havnt had an issues for months, apparently it treats the drive differently, and loads alot more inso SRAM, so the drive is used less…
is the clicking accompanied with a pic of an ipod with a sad face and an explamation mark?
if not, then that clicking is normal, the “click of death” is a repetitive almost grindlike click…
if you every once and a while hear a click or chug come from your 30Gig, its just the HD accessing data
