Not exactly the firmware is HEAVILY encrypted and next to impposble to extract. Also the HDD locks so using it in a normal Pc is impossible you would have to actually use it in the ps2 otherwise the ATA stuff gets screwed. Saving to it will be another issue as well Sony is not about to give up the cash cow of memory cards. The Dms stuff is total BS they are just trying to justify their over priced POS with homebrew crap. Also just flashing the firmware to any drive HA the difficulty here is that you need the exact drives sony uses and how many 40 GB 5400 rpm hard drives do you see in stores these days?
