Thank you once again, Anna! I've gone through what you've said and will
start a new thread with my remaining questions. You've been incredibly
helpful!

Thank you, Anna! You provided so much information that I've printed it
off and will read through it tonight. One thing you said that I hadn't
realized before (correct me if I'm wrong) is that all that differentiates
an internal hard drive from an external USB drive is the enclosure. If
you remove the drive from the USB enclosure, you can put it into the
computer and run it there. If that's the case, it would make sense that
if my internal drive failed, I could simply take the external drive out
of its case and put it into the computer, hook it up, and be ready to
work again.
And if that's indeed true, then I should probably check my innards, as
someone else suggested earlier in this thread. I gather that if my
computer doesn't support 48 Bit LBA, I wouldn't be able to run a drive
larger than 137GB internally. You indicated earlier that you were fairly
sure I would be able to run a large hard drive (presumably inside as well
as externally). Do you think I need to check to make sure?
Thank you again! I'm sure I'll have more questions after I read through
everything you've posted.

Jo-Anne:
First of all, with respect to the 48-bit LBA business...
As I believe I previously indicated I'm virtually certain your Dell
desktop PC supports large-drive capability, i.e., drives > 137 GB. So I
really don't think you'll have any problem on that end.
Again, as I previously mentioned we did run into problems with some USB
external enclosures that for one reason or another had problems detecting
very large hard drives that were installed in the enclosure - mainly
drives that were > 300 GB. That problem appears to be a thing of the past
at least as it pertains to USB enclosures produced over the past few
years. It surely won't be a problem should you opt to purchase a
"one-piece" commercial USB HDD device.
Of course, as you indicate there is an advantage of purchasing the
components separately - the USB enclosure and the HDD of your choice. You
are correct that you could easily transfer that HDD containing a cloned
copy of your internal HDD to your system should you want to replace the
internal HDD because the latter became defective or for whatever reason.
Under those circumstances your system would then be bootable & functional.
Theoretically you could do the same with the HDD in the commercial unit,
however, it frequently is difficult if not impossible to remove the HDD
from its enclosure without literally destroying the enclosure. And
needless to say this would invalidate the warranty should it still exist.
As to comparison cost, the commercial units have fallen so dramatically in
price over the past year or so. that the savings once engendered by
purchasing separate components rather than a commercial unit isn't a
terribly significant factor any more in most cases. But, of course, as
we've discussed you do get increased potential flexibility by using
separate components.
