HFS+ Formatted Drives
The iMac hard drive is formatted from the factory with Mac
OS Extended format, also referred to as HFS+. Norton
Utilities version 3.5 is not compatible with HFS+ and
version 3.5.1 and earlier can result in hard drive
corruption and loss of all data on the hard drive. (See
“HFS+ Formatted Drives” in the Troubleshooting chapter.)
