Not to belabor the issue but just a few extra thoughts for your
consideration (as well as others who might be contemplating installing a
removable HDD in their desktop PC)...

The advantages of installing one (or even two where feasible) removable HDDs
in a desktop PC environment go considerably beyond the obvious one where the
user is working with multiple OSs. The enormous flexibility (and even
peace-of-mind) one gains from this hardware configuration cannot be

With a removable HDD a user now has an *unlimited* number of HDDs at his/her
disposal. Each HDD will reside in a removable tray/caddy and simply inserted
in the mobile rack whenever needed and simply removed when unneeded. Thus
the user could designate one HDD as a backup drive and clone the contents of
his/her source HDD to the designated backup HDD and thereby maintain an
up-to-date comprehensive backup of their system.

Another HDD could be utilized with a different OS as previously mentioned.

And so on & so on...

Obviously with one or more removable HDDs there's no need to get inside
one's desktop case so consequently no need to engage in any complicated or
awkward install/uninstall - connect/disconnect procedures involving a HDD.
Nothing more complicated than opening or closing a small (perhaps 4 1/2"
wide) drawer or turning the mobile rack's keylock switch to the on or off
position. And all this from the comfort of one's computer chair.

And obviously a simple matter to replace a HDD should it become defective or
a different HDD is required for any reason.

How many times does a user desire to install a program but is reluctant to
do so because from past experience he/she knows that there's always the
chance that should the program prove unsatisfactory for the user's needs and
even should the program be subsequently uninstalled from the system, there's
still a real possibility that "debris" (or even worse!) will be left behind
causing a performance hit to the user's system? And, as many of us have
experienced over the years, even worse results can negatively affect a
system following the installation of a mischievous and/or poor designed

These negative implications can be avoided through the use of removable
HDDs. Now the user can simply designate one (or more if desired) removable
HDD as the "sacrificial lamb" so to speak and test out this or that program
or this or that configuration on that designated HDD so as to determine
whether the program/configuration should be installed on their day-to-day
working HDD.

And another level of near-absolute security is available to the user as well
since the HDD residing in its removable tray can be instantly uninstalled
and/or simply physically removed from the system.
