Need help installing new Western Digital 1 TB HDD

I am using a GigaByte UD3P Motherboard.

All drives currently installed:
DRIVE C: CRUCIAL_CT128M225 SSD DRIVE 128 GB [ BOOT Drive ]
DRIVE D: Seagate Barracuda 7200.10 320620 320 GB 7200 RPM 16 MB
DRIVE F: Maxtor 6L080P0 ATA Device DiamondMax 10 80 GB <--IDE DRIVE
DRIVE H: Seagate USB External HDD 250 GB <-- USB

The NEW HDD is a 'Western Digital WD1001FALS 1TB' 7200 RPM 32MB Cache SATA 2 Internal

SPECS on New Drivere here----> Newegg.com - Western Digital Caviar Black WD1001FALS 1TB 7200 RPM 32MB Cache SATA 3.0Gb&#47;s 3.5&#34; Internal Hard Drive -Bare Drive

The section I am reading from can be found here---> GIGABYTE - Motherboard - Socket 775 - GA-EP45-UD3P (rev. 1.1)

START MANUAL SECTION

END OF MANUAL SECTION

Questions:
I need to know if I can simpy put this newest SATA II drive to any unsued SATA 2 cable?
Do I have to remove or move around any drives?
Is there a max supported drives for the motherboard?

Or anything anyone would like to add??

Oh yeah M8....
Just install in ur puter and connect to any of the MOBO unused SATA connections, pwr and data cables.
Check if HD is picked up in the BIOS durning start and or read in the device manager under disk drive
You need not move any of your drives around.....
I would guess that you can connect 6 SATA drives internally and a bunch externally....
luk dude....

based on this...
DRIVE C: CRUCIAL_CT128M225 SSD DRIVE 128 GB [ BOOT Drive ]
DRIVE D: Seagate Barracuda 7200.10 320620 320 GB 7200 RPM 16 MB
DRIVE F: Maxtor 6L080P0 ATA Device DiamondMax 10 80 GB <--IDE DRIVE
DRIVE H: Seagate USB External HDD 250 GB <-- USB

Can I MOVE current Drive D: to drive E: position AND make sure the new TeraByte drive goes into drive D slot?

I hope that made sense..

thanks

Yes you can, right-click on Computer, then Manage, Disk Management, select the disk you want, right click it, and select "change device letter and path" (i guess, i have a spanish version of windows 7), select the letter you want and that's it :)
