Do you get one timeout when the disk powers up, and many ?

This is because there's no wau for the driver to know whenever the drive is
off or not, it has to try a command and wait for it to fail to reset the drive,
which will make it power up.
I agree the code should'nt print messages in this case, but it's hard to
separate this from real error cases.
