What sort of commands? To date I've not had any
problems with
USB2 or USB3 external docking units. I have found no
troubles
that I'm acutely aware of with powered USB
external-drive
enclosures either (Seagate); sometimes I have had
hiccups with
2.5" non-powered bridges, but that's somewhat to be
expected
due to the limited power, especially if the drive has a
motor
issue. Overall I have found recovery via USB-bridges to
be
more dependable than eSATA or SATA directly,
particularly if
the drive resets frequently. Though it's likely a
kernel/driver issue I have found that when directly
connected
to the SATA interface I often have the drive become
completely
no-responsive to the system ( but reestablishes fine if
you
reboot ).
Different anecdotal evidence I suppose.

No matter how much you press out, there's still enough
moisture
in the atmosphere contained in the drive that you'll get
condensation on the actual platters when you pull it out
of the
freezer. If you must freeze a drive, then I suggest
doing so in
a very low humidity environment. I prefer to keep it
between
5~10'C so as to avoid dropping below the dew point.
