Can't tell which hard drive to install Fedora 13 OS to.

[allen at math.binghamton.edu]

PartitionMagic doesn't run on Windows Vista which is what I have.  Also,
space isn't an issue on the Data drive since it is completely clear (all
150 GB of it), so one drive has Windows installed on it with all of my
personal data, and the other drive has literally nothing on it (which is
the drive I wish to install F13 on).  So when I go to install F13 to a
hard drive, I have to choose one of the two drives, and their only
distinguishing characteristics are their serial numbers and whether they
are "sda" or "sdb" which I assume stands for "slave drive a" and "slave
drive b", and I would think that Windows is installed on sda, but
assumptions are dangerous in the computer world.

Thanks for the quick response!
