It is fairly safe w/ the AHCI driver or the SILI driver. It is not
safe with the NATA driver. It may or may not be safe w/ the firewire
driver. It all depends on whether the driver properly aborts any
in-progress I/Os or not, and whether the filesystem then does the
right thing with the error condition.
