I am considering purchasing a laptop, and notice that many BIOSes nowadays recognize external USB devices as hard drives/etc.
I am interested in taking advantage of this feature and rather than buying a dedicated external USB drive, just purchasing a laptop and finding a way to use that as an external USB host drive.
Perfect example of a use of this might be using a hard drive recovery software on 1 machine (while not having to boot into Win XP), and having my laptop plugged in via USB and be detected as an external hard drive. I need this feature for this purpose, as of course I know how to do host-host networking via ethernet, wireless ethernet, USB-USB networking in XP, etc. already. What I need is my laptop to act and appear as a simple USB external hard drive to another machine, on a raw level.
Are there any products that do this? or is a USB (A-A I think) cable all I need? I am assuming this isn't possible, but perhaps some consultant out there uses his laptop as an external drive when in a squeeze instead of bringing along an external drive.
