Error recovery on a device with moving parts is *SLOW*.
For example, recovering from a read error on a physical DVD
can take a whole minute or more.  Just recovering an ATA bus error
can take 30 seconds or more.  I've seen these: one of the SATA
channels on the I/O bridge chip on one of my boxes is flaky.
At first I thought it was the DVD drive, but a new drive
which worked in another box also experienced the same problem.
So now there's a piece of tape over that SATA connector.
