[NTLUG:Discuss] OT: laptop module hard drive

[Fred James]

All
(in particular it is an old Dell Latitude C840 (PP01X)
Mandriva 2007
Mobil Intel Pentium 4 M 1.8 GHz
512 MB memory
40 GB Hard drive
 - if that makes a difference)

In looking into a new hard drive for the little guy, I ran across 
something called a modular bay hard drive - put it in the second bay 
instead of the floppy, second battery, or whatever.

Anyone had any experience with such a thing, particularly running under 
Linux?  Really just wondering if they run, and run well, but I should 
like to any pro/con you may have to offer.

Thank you in advance for any help you may be able to offer
Regards
Fred James
