Ok I got a doosie of a question... got a 300gb maxtor HDD for xmas, external, usb2/firewire. I have this PB15 which I am on now, and then I have a PC i want to hook it to. So my question is, how do I make an 80gig partition on it for my mac, and then do all the rest for my PC? I have tried to use Disk Utilities, but without much success. I've partitioned and formated the volume on mac, then plug it to the PC and then the PC doesnt seem to recognize any of the formatting when i plug in the drive into the PC. So i then used the Disk Management part of windows to make 2 partitions and formatted them to NTFS, figuring I could use the disk utilites program on the mac to reformat one of the partitions to macOS... Well when i try to format it wants to reformat BOTH partitions to macOS, not just the one i have selected. Someone has to know how to do this (the easy way) please let me know. thanks in advance.
