ATA command timeout

[Malcolm Kay]

I recall having the same or, from somewhat vague memory, similar problem 
some time ago. It was about the time when CD drives started being commonly 
installed as master on the secondary port instead of as a slave. At that time 
moving the CD to slave fixed the problem.

But then it might not work with the current round of difficulties.
