Hello, our oc has 2 drives the boot drive is (old)160gb 7200rpm and the new installed (old)320gb 7200rpm.
I want to do a clean install but wondering which drive to choose

The 160gb hdd is hitachi hds721032cla362 ata
The 320gb hdd is st3160815as ata

Also what good program to test the drives

you should use the 160gb drive for install windos on it , the secound drive you can use to install programs and saving youre files
