mcraig78 Posted August 3, 2012 Share Posted August 3, 2012 OK so I am running ML on a GA-EP45-UD3R with a ATI Radeon 4890 and a Pioneer DVR 216MBK, everything is working perfect except I can burn CDR's but if I put a blank DVD in I get the choice of open finder and what not, it shows I can only put 664 MB on it and then if I try to burn my slowest speed I can select is 32x and if I click burn it suddenly stops and tells me communication to the drive was interrupted. I then tried putting the drive externally via USB and get the same results. Any ideas? I have attached my DSDT if that helps anyone. Thanks Here is what system profiler says about the drive: PIONEER DVD-RW DVR-216R: Firmware Revision: 1.02 Interconnect: ATAPI Burn Support: Yes (Generic Drive Support) Profile Path: None Cache: 2000 KB Reads DVD: Yes CD-Write: -R, -RW DVD-Write: -R, -R DL, -RAM, -RW, +R, +R DL, +RW Write Strategies: CD-TAO, CD-SAO, CD-Raw, DVD-DAO Link to comment Share on other sites More sharing options...
