You also MUST format on the Mac, since no mac SCSI software works with Spectre, it can't seem to see any SCSI devices. I used the CMS software to format a SyQuest cartridge for Mac & Spectre usage. As you said, you can't have an Atari partition, although the Mac OS does allow for multiple partitions on a drive. Hopefully, Spectre 3.0 will support a wider range of Mac formatted drives. I'd love to have a cartridge with an ST partition on it that autoboots and still have a Mac readable partition. Since formatting the cartridge and putting a bunch of stuff on it, the volume crashed, although Spectre still displays it under the hard disk menu. Of course, I hadn't backed up anything on it yet (if I had, it wouldn't have crashed). I haven't had a chance to try and restore the volume yet. ---jb

Can someone clarify this?

This sounds very knowledgable and I'm busily trying to figure it out. I have a Supra 80 with three Atari partitions and two Mac HFS partitions which I formatted with GCR 2.65, following the manual instructions.

In short: Spectre < 3.0 supports Mac disk formats from an older System/Finder (probably from when the Mac first got hard disk support). An advantage of a compatible disk format would be to share files between a real Mac and ST with a Syquest 44Mbyte removable cartridge. These files could be, say, 15 Mbytes of public domain Mac stuff. The bare Syquest drive with one cartridge is $468 in an add in MacUser. If you don't need to share a drive, your setup is fine. Note that the older format Mac scheme of Spectre 2.65 and below has a maximum `disk' (Mac didn't really have partitions then) size of 32 Mbytes. Spectre 3.0 uses a format that allows Mac partitions of 256Mbytes. Paul Wick -- cacsc083@mx.csun.edu

Has anyone out there done this and could they >Pleeeze give me some tips. You can *NOT* format a hard disk on the ST that both a Macintosh and the Spectre can use. The partition map that Atari defined for the ST is not compatible with the partition map that Apple defined for the Mac. This will stay true no matter whose partitioning software you use on the ST. Spectre does *NOT* repartition the hard disk or change the format of the partition map to the format Apple uses. Spectre just changes the type of the partition to 'ACK' (or 'OOP' in version 3.0) instead of 'GEM' or 'BGM' or whatever. After Spectre changes the partition type in the map it then writes a Macintosh file system (MFS or HFS) in the partition. You can format/partition hard disks on the Mac and then use that hard disk with Spectre. This works great, especially with removable media drives. (With Spectre 2.65 you need to use older Mac formatting software since it doesn't understand the new Mac partition maps. Spectre 3.0 supports both the old and new Mac partition maps.)

The 32 meg and 256 meg limits on partition sizes are actually limits of the Spectre formatter. Spectre supports much larger partitions, as long as the disk is formatted on a Mac. Macs have always supported hard disk partitions. But when the original partition system was developed there was no reason to partition a Mac disk since nothing existed to use other partition types (no Unix(tm), etc.).
