If you are installing a SATA PCI or PCI-X controller card to which you are attaching >128GB SATA drives, you can partition and use the entire drive as a single volume, or multiple >128GB drives in a RAID 0/1 volume. These add-in SATA cards all support >128GB drives, are not affected by the limitations of the built-in, on main logic board, PATA controller, or firmware limitations. All current add-in PATA PCI/PCI-X controller cards also support drives >128GB in any partition scheme, as well as software RAID 0/1 volumes. The limitations of the main logic board built-in PATA/IDE controller do not affect PCI/PCI-X controllers cards. The limitations of the main logic board built-in PATA/IDE controller can be avoided by use of an Open Firmware hack that enables large drive support. The only drawback to using the large drive hack is if the PRAM/NVRAM is reset, the on-board IDE controller limitations on drive and partition size are reinstated until the hack script is run again. This is true on all Macs prior to the 2002 QS, which supports >128GB drives natively, as do all Mac systems since. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
