my roommate asked me a question regarding this. His boss has 2 macs: a CRT imac, and a powerbook G3 laptop, both running OS 9, with a total drive space of 60GB. His boss just recently picked up a few (3, i think) 120GB firewire hard drives, so he can back up the data on the machines. When he transfered the data however, he filled up 2 of the drives! how does 60gb stretch to 240GB?! what should he do? thanks in advance.
