Running 2 Drives simultaneously?
So I have yet another query which requires the genius of the users on Unix.com. Having asked around at my work (Tech company) No one can really answer my question thoroughly.
My goal is to get 2 Hard drives running at the same time and allow me to switch between working on one to the other. However, the catch is that both the drives have different operating systems. 1 Windows XP, 1 Linux. The theory to me seems virtually impossible but I'm hoping there is a way for it to work. The drives would not be used to share info between them, merely running at the same time. My reason for doing this is because I am a working man and do not want to purchase a separate setup to be able to perform this. Now if this just a hopeless wish I understand and appreciate everyone's time for looking into it however briefly. Thanks to all.

SBP(4) BSD Kernel Interfaces Manual SBP(4)
NAME
sbp -- Serial Bus Protocol 2 (SBP-2) Mass Storage Devices driver
SYNOPSIS
kldload firewire
kldload cam
kldload sbp
or
device sbp
device firewire
device scbus
device da
device cd
device pass
DESCRIPTION
The sbp driver provides support for SBP-2 devices that attach to the FireWire (IEEE 1394) port. It should work with SBP-2 devices which the
CAM layer supports, for example, HDDs, CDROM drives and DVD drives.
Some users familiar with umass(4) might wonder why the device is not detached at the CAM layer when the device is unplugged. It is detached
only if the device has not been plugged again during several bus resets. This is for preventing to detach an active file system even when
the device cannot be probed correctly for some reason after a bus reset or when the device is temporary disconnected because the user changes
the bus topology. If you want to force to detach the device, run ``fwcontrol -r'' several times or set hw.firewire.hold_count=0 by
sysctl(1).
Some (broken) HDDs do not work well with tagged queuing. If you have problems with such drives, try ``camcontrol [device id] tags -N 1'' to
disable tagged queuing.
