Enermax USB enclosure

[mal content]

Anybody had any luck getting one of these working?

It's specifically an Enermax External Enclosure EB305C,
IDE/SATA to USB2.0.

Upon plugging in the device, with an unformatted Maxtor
(hack, spit) hard disk:

And:

$ ls -alF /dev/da0
crw-r-----  1 root  operator    0, 126  2 Jul 13:02 /dev/da0

Any attempt to do anything useful with the disk just results in
the following:

$ sudo fdisk /dev/da0
fdisk: cannot open disk /dev/da0: Device not configured

I've noticed that even Mac OS X seems to get the disk sizes wrong for
this disk, it thinks that it's a 2TB (!) drive when it's actually 160gb.

Any help would be welcome.
