_Probably_ no hardware damage, but I do not know for sure. I do not it
will likely lockup, and data corruption is also a possibility.
As I mentioned in another email, ICH5 hardware does not support hot
removal. HOWEVER. If the OS driver is given sufficient notice, it can
shut down the port, and the sysadmin may then unplug the SATA cable.
As a tangent, your TX4 hardware fully supports hotplug, but libata does
not yet support it.
