Archos 504 replace hard drive

[amialive]

Hi, could anyone tell me if there is a way i can replace the hard drive in an archos 504 myself, i have previously formated the drive and used it in an old laptop with the intention of installing a larger drive in the 504 at a later date. i've since learned that the system looks for a serial number programed in the drive by the manufactures and will not boot up if it cant find this number during the booting process. is there a mod to bypass this.. thanks for any help guys.
