Got my new build put together and did a quick & dirty install of Win7 and a couple reboots. Everything works pretty well, now I want to reformat / re-partition them and set them up to my liking.

My config:
Phenom X4 9950 Black AM2+ 2.6ghz (quad, 64-bit)
Asus M3A78-CM Motherboard
OCZ DDR2 PC2 6400 RAM - 4gig
Saphire Radeon x800 Pro, PCI-E
Seagate 10k-rpm SATA HDD 120g
Seagate 7.2k-rpm SATA HDD 500g
LG 22X DVD-RW SATA
500w PSU

I wanted to partition the 10k HDD as:
30g C: for OS (win7 64-bit)
30g D: for Apps
remaining 60g E: Data

and the 500g drive for MP3's, videos, and backups (I have A LOT of music (>500gig, I backup to an external drive too).

I bought the 120g HDD used from my friend, so I want to clean it off and reformat/repartition it before doing the Win7 install (it still had my friend's OS still on it (now windows.old) and my new Win7) install.

Main question:
Can I run Seagate tools from a CD to cleanup the HDD before the fresh install? or is there a better way to set it up for the OS install?

I also saw a product called Active @ Kill Disk, can I run this from CD? (looks like they have a DOS version.) should I run this before or after the reformat / repartition? (I'm guessing before(?)
Kill Disk

any suggestions / feedback would be greatly appreciated. ( I am barely familiar with Win7 and have a lot to learn!)
