I tried yesterday to fit in a 40GB hard disk out of a 4G ipod into the C3000 Z.
The plan was to replace the internal CF disk with the ipod hdd - with about 2cm sticking out. To do this I had to make a new gap from the silver plastic above the CF entry point and extend the CF entry point on the white plastic.
After about 2 hours of opening, unscrewing, ripping bits of plastic, the new hdd fit in (with the bit sticking out on the side, hey I didn't care, was going to have a 40GB Z !).. it just wouldn't power on.... the ipod (toshiba) disk is 3.3v - same as the microdrive... to power it back up you need to run it off the battery for some reason, then plug in the adapter... otherwise if you try to power with the adapter, it light would keep blinking and nothing happens...
so i closed everything up again and put the original 4gb in there and it is back to normal except for the large gaps...
If anyone has some pointers im willing to try it?
maybe a 5G ipod disk which is a little thinner might work?
