I am building a new Mini Tower using the Antec Sonata mini tower. It has the Gigabyte 875P P4 Titan series Mb and a Pentium 4 3.20E GHz, 1.4Vmax, System Bus 800MHZ, 1mb L2-Cache processor. It also has a 1 gig of ram and an AGPTEK GF FX5200, 128M DDR TVDVI graphics card ans two SATA drives. One is the WD360GD-00FNA0. The other is the WD1600JD-00GBB0. If I don't set them up raid-0, when I try to load the O/S they cannot be found. If I do set them up raid0 they can be found but cannot be formated. The O/S claims they are damaged. This is all brand new from Computer builders warehouse and this is my first experience with SATA drives. There are no IDE drives in the tower.
