Just a little tip which I've never seen before, but solves alot of the
problems invovled in partitioning drives during a Linux install.
</blockQuote>
<blockQuote>
Rather than go to the trouble of partitioning the hard-drive on a
functional Windows system (is that an oxymoron?) I simply placed it in a
hard-drive caddy. When it came to installing <A HREF="http://www.redhat.com/">Red Hat</A> 7.2 I replaced the
drive in the caddy with a second drive I happened to have from an
obsolete system. Now, by simply inserting the appropriate hard-drive in
the caddy, I can boot into Win98 or Linux with no more effort than it
normally takes to use a Linux boot-disk -- assuming, of course, that
your system BIOS allows to autoedetect the hard-drive on boot-up.
</blockQuote>
<blockQuote>
Just a few comments on the advantage of doing this;
</blockQuote>
<blockQuote>
It can be a cheap way of getting into Linux as it's actually cheaper to
buy a new hard-drive and caddy for install in a new system than it is to
go out and buy an old 486 or Pentium I (or whatever) -- it also takes
lot's less desk space!
</blockQuote>
<blockQuote>
It has the advantage that the Linux and Windows installs are totally
independent -- a crash on one has no chance of effecting the other
whatsoever and it circumvents the problem that later versions of Windows
have to be the only OS on a system.
</blockQuote>
<blockQuote>
The one draw-back is the need to add a second (third?) hard-drive to
allow swapping of files between two OS's.
</blockQuote>
<blockQuote>
Finally, I'm not a developer or hacker, but I imagine using multiple
hard-drives would also be a great way to experiment with new Linux
distro's or versions (or even software packages) without risking damage
to a known and trusted installation.

Hi again,
</blockQuote>
<blockQuote>
I just recieved the following warning about the use of hard-drive
caddies which I thought ought to be attached to my dual-boot system
idea;
</blockQuote>
<blockQuote>
Thanks to "Dutch" for the following insights.
</blockQuote>
<HR width="10%" align="left"><blockQuote>
You make a few good points in your post. Now from 10 years as a
hardware technician I'm going to inject a few cautionary notes.
</blockQuote>
<blockQuote>
1) If you are going to use a caddy system, be sure you get a decent
one with solid, well designed alignment rails and good heavy duty
connection pins. Over time the cheap ones can become mis-alligned and
cause bent pins on the internal connectors. Best case the drive won't
be recognized, worst case is a short causing damage to your system.
</blockQuote>
<blockQuote>
2) Along the same lines, most removable drive setups do not make solid
metal-metal connections to conduct heat from the drive into the case
where it is dissipated. So any caddy worth buying should have a
cooling fan of some sort built into the tray.
</blockQuote>
<blockQuote>
3) Make sure to wait (usually a good slow count to 20) until your
drives have COMPLETELY spun down before you remove them. Removing a
drive that is still spinning is just asking for damage to the
bearings, heads, etc.
</blockQuote>
<blockQuote>
4) Treat the removed drives with care (like they were delicate glass).
I've seen people yank a caddy out of a machine and just drop it on
their desk like a book. How long do you think something as delicate
as a hard drive can take that kind of abuse?
</blockQuote>
<blockQuote>
5) Be extremely careful of static discharge, especally around the
connection pins on the back of the caddy. ESD can kill a drive in a
caddy very easily since the drive is not attached to any sort of
protective ground.
