Does first-generation SATA hot-plug without killing the mobo, the
disk, or both?

I've got a PC with an ASUS A7N8X-Deluxe mobo with SATA on it. It's on
the bench and I have several SATA disks I want to run disk fitness
test on. (The boot/OS disk is IDE.)

Do I have to power-cycle the machine when I hook up one of these
disks?

The PSU has SATA power connectors. Do I hook up power or data first?

The OS is eaith w2k or Linux.

You cannot damage the hardware this way. But beware that standard
PC power-plugs are _not_ hot-pluggable, only SATA power plugs are.
Some old SATA disks have both. With the standard PC power plugs
you can kill the disk when hotplugging.

That may happen, since not all SATA controllers support hotplug.

Does not matter.

Install the drivers (Linux: in the kernel or as kernel module)
and see whether the disks are found. If not, you need to
power-cycle.
