Hi, Ive been wondering about the 4GB hard drive that Ive seen at Hastings for the PSP. Its an actual 'moving parts' hard drive instead of flash memory, but its kinda rediculous since flash memory is cheaper, smaller, and the same size (or bigger now). Ive been unable to find anywhere on the net about modding one. I cant afford to buy one just to most likely break it. My idea is to replace the hard drive with a 30/80 gig from an ipod/zune, etc. If the interface is compatable and it would recongnize the extra space wouldnt it be awesome???
