XP installation, hard drives question

Hello

I have two hard disks in my computer, one Seagate SATA 120 GB, and
another maxtor ide 80 gb

I want to install XP on the SATA because its a faster disk.
When I start to install XP I have to put the diskette with the drivers
so it recognizes the disc.
My question is the following. If I have connected the IDE disk and the
SATA disk and I tell windows to install itself on the sata disk, it
assigns the drive letter "c" to the ide this and "d" to the sata and it
installs XP on "d" drive(sata).
To avoid that(cause I read someplace that isnt a good idea to install
xp on a drive letter different than "c" ) i unplug power from the ide
disk, install xp and after its installed I plug it back in. Then XP,
assigns the letter "f".

Is this normal behavior? Could this be causing any problems on my C
disk?
Thanks in advance,
-Dan

To circumvent this issue, my next PC build will consist of only SATA (HDD's and DVD/CD ROM). Can't you install drivers from floppy during XP setup to install XP on SATA as drive C properly?
