Hi all, MacBook early 2008 2.4 Intel Core 2 Duo running 10.6.8. Need some help. 1) Internal SuperDrive no longer read DVDs so I replaced with a new one. 2) Have been happily burning onto DVD-DL. 3) Today, installed Wine and Wine Bottler in order to get a Windows app, IMG Burner, as I needed to create an ISO from a BDMV 4) Ever since then, SuperDrive won't burn due to medium write errors but it will READ existing DVDs, boot DVD Player, etc And: 5) The name of the SuperDrive in About This Mac is HL-DT-ST DVD+-RW GSA-S10N ATA with Burn Support = Unsupported in Disk Utility. I'm sure the name prior was Matshita etc etc - it certainly was a brand name. Googling HL-DT-ST DVD+-RW GSA-S10N ATA comes up as a Windows Driver. Therefore: I'm surmising I've accidentally loaded a Windows driver (during the Wine emulation) on my SuperDrive. Have deleted Wine and Wine Bottler as much as possible. Any ideas if I'm on the right track with that diagnosis or any ideas on how to fix - other than buying ANOTHER new SuperDrive? Thanks in advance.
