Yeah, apparently this shortens the max cable length to 1 meter. In this case
I've got a 1 meter external cable and approx. 30 cm internal (heavily shielded
though) cable from the bracket to the SATA port. Anyway, the drive works
perfectly if plugged at boot time.

I repeated the experiments and dumped as much dmesg as I could.

The dmesg outputs of both experiments are attached and commented. It seems
that in the case the drive is pluggin at boot time, it remains hot pluggable
later (be it with some strange error messages) after all (or is there another
factor that I did not reproduce?).

Thank you for any help. =)

NO CARRIER
### First experiment, the drive is plugged and turned on at boot time.
### The initial full dmesg dump follows.
