Dear Soft Reset,
Thanks for your reply.
1) On my old SuperDrive, works both ways, i.e. before and after reboot.
2) The device driver is there (MacBook Air SuperDrive, AppleODD.sys, version 2.0.2.2), but has a warning, Code 18, reinstall the driver. Yep, I know windows %$#, but I need to run some business applications.
What, I did:
1) Reinstall the driver (uninstall , reboot , install again)
2) Reinstall Boot Camp 2.1
I have for sure something missing, but until now, no clue.
