Only if the external hard disk is only connected via fibre optics cable (SAS or similar) instead of copper cable. Electrical surges and short-cirquit faults tend to kill the server and the attached hard disks at the same time.

As far as I know, commit hooks can modify the commit. (This behavior is discouraged, but nevertheless it is possible.

Only if the disk is connected to a different power source, otherwise it doesn't much matter whether it's killed via data cable or power supply. (Also, this will in most cases only kill the drive electronics; there is still the possibility to have the driver platter to be installed into another drive, by professional recovery services.) But the simplest ist to disconnect the external drive and to use two or three in cycles (if that hadn't been mentioned here), and take the others home or another location different from the servers's.
