Ok i am using hd advance 1.0 from a MC exploit. My Ps2 stuffed up and i was wondering if i buy USB extreme and a IDE TO USB cable would i be able to use my Existing hdd with the USB extreme software i dont care if i have to format it as there isnt many games on it. if you have any further questions please email me Butiamcool@hotmail.com
As sly_61019 says you still would need a form of power for the hdd and the only way for that is to buy a hdd enclouse. Have a look on ebay for those, there only like $20 or less.
The third thing is I thought PS2 USB ports only support USB 1.1, which that cable does not, so it wouldnt work anyway.
