+5V only, and not enough watts to drive most hard disks.

This connector was meant for an internal Zip drive, and can be used with a
_2.5"_ IDE drive with appropriate adapters (both are low power, +5V only).

If you want to put a 3.5" hard drive in there, you need to watch for heat
concerns, and run your own power line to the drive from a power supply that
can handle it.

Note that if you run power to the drive from another PS, you can also power
the Shark through that 4-pin header from the same PS.  I do that on my
(Shark-based!) web server.
