Correct. > >For the MAC cd-roms, same thing but from MAC formatted drives/disks. >The MAC CD-ROMs should be in HFS format. Also correct. You can also do Mac-readable ISO9660 CDs that preserve Type and Creator codes ("Apple Extensions" to ISO9660) if you want one format that can be read by both platforms. The Mac can also read standard ISO9660 with no problem (without Apple Extensions, but you don't have Type-Creator code info on this kind of disk) > >We aren't completely sure we can create both these kind of CDs from >only one machine.

Yes you can, from a Mac (and possibly also from a PC - though there are specific considerations when authoring an HFS CD that make me nervous of saying Yes outright). HFS disks are written on a volume (rather than a file-by-file) basis. Mac authoring software that allows file-by-file selection for HFS disks requires that a CD-image is written to disk first, before that image is written to the CD itself. If you have the ability in EasyCD to select a Mac SCSI partition that has previously been correctly sized for CD63 or CD74, optimised and dismounted properly (so as to not set a specific flag that causes CD mounting problems) then you should be able to write an HFS CD by doing a block-for-block copy of the partition to the CD-writer ("Block Image Copy"). > >On the MAC, we don't know.

The Mac can happily read PC SyQuests (I use AccessPC v3 and MultiDriver from Insignia) and DOS floppies and you can manipulate the files from these on a Mac partition with no problem. Most Mac CD-R software requires that an ISO image is created on disk prior to recording a CD. You must NOT do a direct block-for-block copy of a DOS partition to CD in ISO format as this will not work properly. > >Or, should we just get 2 pre-mastering packages, one for a PC and >one for a MAC, and move the CD-recorder from PC to MAC depending >on which type of disk we need to make? Could do, but if you can source network software that allows a Mac to see PC volumes (eg Netware) or a PC to see Mac volumes (eg PhoneNet AppleShare) then you could access everything you need via Ethernet and do the authoring from a Mac with no problems. I have e-mailed you (to spare the eyes of people who've seen it all before on this group) some info on the Mac CD-R software that I use. > >Thanks.. > >-- >Doh No problem - intelligent questions and vital that they're asked before taking the plunge.
