You will need to flash the EEPROM in order for it to work with the Xtremed hard drive. One way to do this would be to use the Turbonet install CD or simply install 2.5Xtreme on a different drive and let it flash the EEPROM for you. When it's done, swap the drives and run the 51killer.tcl script or do a Clear & Delete Everything to get rid of the error 51 message.
Please don't PM me or any other members looking for personal assistance. You'll do better by posting (after you've exhausted the search feature, of course) and taking advantage of the collective expertise of the membership instead of a single individual that may or may not be able to help you. Thank you and enjoy your stay at DDB!
