The standard Apple partitioning of an HDD is into five, four of which are invisible. The mountable data 'volume' is the fourth. If the fifth is a second 'volume' on the drive, the original fifth becomes the sixth, and so on.
Partition 1
Name: Apple
Type: Apple_partition-map
Partition 2
Name: Macintosh_SL
Type: Apple-Driver43 •
Partition 3
Name: Macintosh_SL
Type: Apple_Driver_ATA
Partition 4
Name: name of visible volume
Type: Apple_HFS
Partition 5
Name: Extra
Type: Apple_Free
The 'driver' lives in the second partition. The 'Device Information' panel of the GUI of Silverlining v6, which is much more immediately informative than Silverlining v5, lists the partitions and their sizes.
Although all third-party disk utilities adhere to Apple's five-partition scheme, they provide their own versions of Apple drivers in the second partition. These can usually overwrite a pre-existing Apple driver, although InTech's HD ToolKit also baulks at other makers' drivers. But not so with the converse case. Unhacked Apple disk utilities are diffident about treading where non-Apple drivers have already trodden. This may be also a consequence of differing action by the utilities. Silverlining uses 'Create File System' as the term for the partitioning exercise. This happily overwrites all data on a drive. 'Formatting' the drive in Silverliningese is a much longer process of preliminary zeroing. Apple tends not to be with the pack when the terms zeroing, erasing and formatting are bandied about, and the utility may not do what you think the term implies that it has done.
One indication of this is that if one does format a drive with a non-Apple utility, if the option to 'Update Apple drivers' is taken early in the installation of a new System, the Installer will whinge that it cannot overwrite the 'interloper'. I find that it is best to disable the option before installation begins. If you 'erased' with Apple's utility, you may not have gone the whole hog in replacing the previous driver.
