Sounds like a good idea now, but i would not do that because you might want to use the drive for something else down the road... say you get a new 100 gig drive, and you want to use your old 60gig as a "slave" ... well, you wont be able to use them together like that! Your soldered drive will be "stuck" as a "single" or "slave" or whatever the jumper settings is that you soldered.

not a good idea IMHO.
