It is generally recommended that you use the hard drive with the better stats as your primary drive...

Most likely this will be the new drive...

With that 60 gig I recommend that you partition it as follows

c: 10 gigs
d: 25 gigs
e: 25 gigs
Old drive
f : 20 gigs
g : 20 gigs

Only have the OS on the C drive...
d: install programs to
e: install games to
f: data drive, ftp stuff and back up of data from d and e
g: install testing software / demo's or stuff your going to delete..

That way if you need to reinstall the OS only the c drive needs to be formated... and u do not lose any data on a rebuild.

If you MOBO can handle auto detect... then no problems on installing the new drive...

If not switch the pin on the old drive to slave and on the new one to master...

H : and beyond will be your cd roms dvd roms etc...
