However, if you have only got a stuffed lens unit then you are in luck. I have not tried doing a servo board repair to this model yet. then you might have more trouble, as there is no input for the lid sensor on the DC unit. If you have got a stuffed servo board in a Vers. Ensure that have tucked the red and white wires away so not as to interfere with the lid sensor. You will need to disconnect all of these, insert the new servo board (next picture) and place the cables back in exactly how you found them. You will find three cables, a long ribbon cable, a two pin cable and a four pin cable. If you have need to change the servo board (which I had to) you will need to fully disassemble the DC unit, removing all the metal shielding pieces. The Red/White cables will need to be tucked away so as not to get in the way of the lid sensor. Do likewise in the GD Rom unit and switch the parts. Simple unscrew and remove the drive from the Dreamcast as a whole unit. You can still swap parts in this version, but the DC drive will need to be fully disassembled and made to fit the different housing. Look at the difference in connectors (in red) this will be a dead giveaway as to what version you have.

It does not have the connector needed to do a 1:1 swap and you will have to full dissemble a drive to get this to work with swapped DC parts. On the right is the second / (earlier?) version drive. Also, in the next pic, you can see boxed in red is the DC’s GD connector. You will know if you have this version unit if there is a “3.3v” logo stamped onto the metal. The one of Georges on the left has got a whole DC GD lens unit in it, complete with all relevant connectors to do a 1:1 swap with a Dreamcast. It is important to note that there are two main types of GD Rom drive that I have come across. Diagnosis either burnt out motor or bad servo board.
The drive was spinning but the laser assembly could not move. However, I took the cover off the drive and taped down the lid sensor. I fired the system up and could not hear any activity other than the fan spinning. The broken GD-Rom drive in question belonged to George, and it was giving the error message “Cannot Access GD Rom Drive”. If you have got a GD-Rom drive giving you an error message “Cannot Detect GD Rom Drive” and you are 100% sure that you have checked all connections, then I’m afraid that this guide can’t help you as you need a rare and expensive part which unfortunately, is not part of a Dreamcast.

The good news is that depending on the error code that your GD Rom system is giving you, repairing the drive using cannibalised Dreamcast’s are a real and cheaper possibility. However, purchasing a new GD-Rom drive unit costs about $160USD which works out to be a tinsy bit more than buying 5 or so second hand Dreamcast’s. The Sega Naomi, Naomi 2, Chihiro and Tri-Force all employ the same drive used by the Sega Dreamcast.
