hey guys, a quick question, i just upgrade my xbox hdd to a 60 gig maxtor i had laying around and after installing it and formatting it, all of my applications ran o.k. but i thought that it had to be locked and so after taking the drive off and connecting it to my pc to lock it, once i did, it no longer wants to boot, and i get a message stating it needs service. i dont play live, so would it be ok to leave it unlocked? one more thing, does anyone know of any tutorials of how to adjust the pots on the laser, and check with an ohm meter-phillips drive? Also, if i wanted to replace my dvd-rom drive, can i replace my Phillips with a Thompson?
