If your Apple G5’s hard drive becomes corrupted, if you want to reinstall the operating system onto a clean drive or if you want to sell the machine without giving away your personal data, you can format the hard drive using the Mac OS installation disc that was included with the iMac. Once formatted, the hard drive will be wiped clean and the computer can be safely sold or discarded, or a fresh copy of the Mac OS can be installed onto the disk without risk of file corruption issues.
