Hi newbie here. I have a new 1TB Passport USB 3. I would like to use it to back up two computers;
iMac 3.06 Ghz Intel Core 2 Duo OS 10.6.6 with an ancient WD 250 GB external Model WD2500B011
iMac 800 Mhz PowerPC G4 768 Mb, OS 10.4.11
The instruction sheet stated the Passport is pre-formatted for Windows and to to go to support.wdc.com and download instructions how to reformat the Passport for Mac, but there are several choices for OS 10.4 and 10.6, which should I use?
Is there a way for me to also back up the older WD 250 GB external as well?
