The last post in your link states "Thanks for the responses, but I think its hardware related now.
A couple of hours ago I went back to do some more testing, the drive wouldn't even open, and when I tried to eject the drive from My Computer, the computer would freeze up.
Figuring it was more likely hardware with this information I swapped drives with my friend. His drive burnt 4 disk's fine in my computer, and my drive started up fine in his, but once we tried to burn something it froze up and we were un-able to eject the media.
Will have to send it back I guess. Thanks for the help."
So,looks like you might have to do the same.
