I am rather new to Mac OS and was considering upgrading the HDD of a G4/400/AGP from 10GB to like 40GB or more. Are there any limitations ? It looks like a standard IDE HDD (atapi) - Can I use PC driveimage to simply copy the entire drive to the NEW HDD and the mac will recognize the new disk area ? Can I simply use any mfg HDD like Maxtor or Western Digital, etc. ?
