Replaced GSA-S10N will not burn discs
I replaced a clients SuperDrive in their A1181 with a brand new GSA-S10N SuperDrive (it's stated on this site that this drive will work in this machine). Other than it being louder than the original drive (are they usually?) it played CDs, DVDs and read discs just fine. We returned it to the client and collected for the job. 3 days later the MacBook was returned to us as the drive still played/read disc but it would not burn CDs or DVDs at all. Out of iTunes the disc wouldn't even make it past the initialization stage and would return a "medium write error." What are we missing here?
