I've bought second SATA drive for my Mac Pro (BluRay). 1. Installed as SATA to one of the ODD ports - works fine as AHCI, no boot. 2. Installed as IDE with 4World SATA/IDE converter - Superdrive as Master, BluRay as Slave - works fine but only UDMA33 + booting. 3. Bought another chinese adapter - there is not MASTER/SLAVE switch on it :/ Installed BluRay alone - works UDMA66 + booting Installed BluRay + Superdrive as Master - not working Installed BluRay + Superdrive as Slave - not working Installed BluRay + Superdrive as Cable Select - not working Any ideas ?
