HFS is the name of the Apple Macintosh file system. Nero can burn so-called Hybrid CDs (which contain both ISO 9660 and HFS data; see 'Creating a Hybrid CD') and 'pure' HFS-CDs (which can only be read on Apple Macintosh computers!). An SCSI harddisk with the HFS data must be connected up to the PC for this to work. The data can only be generated and edited with an Apple Macintosh PC. The layout of the file icons, the drive icon and the window positions on the Apple Mac are defined by the settings on the selected HFS partition.
When connecting the hard disk with the HFS data, the SCSI harddisk must of course be connected and powered up before the PC is turned on. There must also be no duplication of SCSI device numbers. You should also ensure that the HFS data do not exceed 640 MB otherwise they will not 'fit' on the CD.
This opens a dialog box with list of available HFS partitions. If the list is blank then no SCSI harddisk with HFS data has been found.
You will now see the familiar Nero tab where you can start the write process in the normal way.
All settings on this and the other tabs can now be reviewed and changed if required.
