You can achieve this for any size drive larger than 128 GB by selecting precisely two partitions, and setting the first partition to be precisely 131,072 MB, then "lock" both partitions. Anything above 131,072 MB becomes the remainder. Then, selectively go back and unlock the partition which is below 131,072 MB and "split" it as desired. Then "lock" it/them again. Do the same for the partition above 131,072 MB. Finally, select "partition" and you are done. > You say it is not a hack, and you may well be right.

The large drive function is a protocol change which requires that the command's data be supplied to the chip in two parts. Only one part is needed for drives which are smaller than 131,072 MB, whereas two parts are required for larger drives. Enabling the LBA48 property enables the two-part protocol, whereas disabling the LBA48 property returns to the one-part protocol. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
