|There is no such thing as Master/slave with SATA drives. There are no Master/slave jumpers on a SATA drive. If they were PATA drives you would have three Masters and three slave drives.|
Master is a hardware configuration, nothing to do with Windows. Windows can boot from a Master or a slave drive, all it needs is a primary partition..
If you had six SATA drives one would be designated as the boot drive and that would be it.
