if you took a look at that link in my previous post. (which actually linked to command-tab.com) the guy fit a 300 gig 3.5in hdd to his ipod. the larger 1.8 in drives can be used in any generation of ipods. the tricky thing is partitioning the drive correctly and loading the right firmware. in might just be worth it to try it out. i would try it out on my 1st gen but it unfortunatly was unpluged during a fimware upgrade. it is forever dead.

here is a link directly to the ipod-super mod guide at http://www.command-tab.com
