If the connection is good and solid, and the drive caddy is fully seated in
the rack you are good to go. Before your computer will be able to access
this drive the rack must be locked down. This is done for two reasons,
one to keep the rack from being removed when the computer is on, and
two, to stop people from easily taking your harddrive.
I suspect only the first one is really accurate though. A really
cheap lock on the front of the rack mechanically stops the drive caddy from
being removed, and also enables power and IDE signals to reach the harddrive. A
small LED lights up when everything is working properly.
When you want to remove your hard drive from the
rack, simply unlock the thing, and while your computer is off, lift up the
handle and pull it out. At that point you can store your harddrive in a safe
location or take it with you to another computer, so long as it has the same
kind of rack.
The only downside to this rack is that if you have it out
for extended periods of time, you are basically leaving a big giant hole open
in the front of the case for dust to enter. For its price, it is a pretty decent
piece of plastic, but I suspect if you were to ever experience problems with
a hard drive, it could quite easily be traced back to this removable drive
rack. And as far as protection for your drive, don't expect too much in the way
of shock protection should you ever drop the caddy.
Otherwise, I'd have to agree that they kinna make any computer look a
bit more 'powerful,' so maybe it's really just good image builder for your
