The drive does not need to be plugged in.
I should have been more clear with my instructions.
First, at the "~ 'your user name'$" line, type 'login' and press enter.
'Login:' will appear
type your user name (the same way you type it to log into your account on your computer) and hit enter
'Password:' will appear
type your password (the same way you type it to log into your account on your computer) and hit enter
you will now see the same line 'Computer-Name: ~UserName$'
but now you will have the access required for a sudo ('super user do') command
at this point, type:
sudo nvram boot-args=”mbasd=1″
and hit enter.
then type 'exit' and hit enter (this will log you out)
again type 'exit' and hit enter and you will see:
Now restart your mac and your super drive will work.
Great stuff, Stephenfromhalifax has really good news. Unfortunately, I tried and tried the Superdrive replacement route with the external usb Apple superdrive. I was not able to get it to work, so I returned the drive back to Best Buy and bought the LG GE24 DVD/CD drive. I plugged into my iMac and worked great. I burned a few CD's just to make sure. It seems to be much faster than the Apple superdrive, but unable to verify. The cost of the LG unit was 45 bucks, on sale. It is USB and it has a separate power cord, not driven by usb. Any way I am very pleased with the replacement drive
I tried the above but it didn't work. After some googling I found this link and I followed the instructions and it worked like a charm. The command above does the same thing as this. But here we are manually going and editing the file to add that entry.
I am burning a movie from my iMac which is hooked to a superdrive right now..
Hope this helps.
Just to update this thread:
I got the late 2012 model iMac, which has you know doesn't have a CD/DVD drive. I purchased the Apple USB SuperDrive to use with it. I installed Parallels Desktop 8 and Windows 7 and I use the Apple USB SuperDrive in the Windows/Parallels Desktop side with no problems (which is what you would expect with the late 2012 model).
Thanks to everyone who has replied, I appreciate the help
