Lower 8-GB is a problem for me |

I have a 7600/120 PowerMac with Crecendo G3 upgrade. I needed a bigger internal SCSI hard drive, but the cost was prohibitive. So, I bought a PCI/IDE adaptor card with a 20-GB drive on the card. I'm pretty sure I could install OS 10.2 if I had a way around the lower 8-GB problem. Would I have to unplug my 1.02 GB Internal SCSI Drive (the original drive) to make my machine think that the PCI/IDE drive was the lower 8-GB? Suggestions? Tom ctomwilson@attbi.com |

Some of the IDE cards actually appear as SCSI to the mac system. If so, the lower 8g rule dissappears. This is one of the reasons I chose the Acard AHard 66. I am running a 60G Maxtor off it as one partition. No problems (yet (6months or so)). Marty |

The SCSI and IDE drives are totally separate and do not affect each other. You can keep the SCSI drive in your computer. The "lower 8GB" means the lower 8GB of the 20GB drive. The 20GB drive can be partitioned to look like it was more than one drive. To Install OS X on the drive you need to initialize the disk (you can use the Disk Utility from the OS X Installer (don't forget to select the "Install OS 9 Drivers" option)) and repartition it into at least two partitions. The first partition must be less than 8GB. Once the drive is partitioned you can install OS X on the volume that is < 8GB in size. The 8GB limit is a restriction incorrectly enforced by the Installer on machines that don't really have a problem with where OS X is installed. The original problem occurred on old Macs with drives connected to built-in IDE controllers (beige G3). The problem does not apply to drives connected to third party IDE cards but the Installer complains anyway if you try to install OS X on them. If you don't want to repartition your 20 GB drive into <8GB and >12GB partitions, then you can try one of the following: 1) You can plug the 20GB drive into a new Mac that the Installer won't complain about, install OS X on it and then move the drive back to your old Mac. 2) Or you can borrow another drive, install OS X on that, then copy it back to your 20GB drive using Carbon Copy Cloner. |
