I am looking into a Rodime 100Meg HD for a GS and mybe a Mac II down the road. What I need is a Prodos8 partition, a MS-DOS (for use with PC transporter) and a GS/OS partition. Does using the Apple SCSI card help? Is this even possible? Any suggestions for partition sizes? I like the idea of separate volumes for each OS.

Sorry, but you'll be a lot happier if you learn to like separate partitions for each *file system*. GS/OS is not a file system and there is no such thing as a "GS/OS partition", since GS/OS reads already existing file systems (such as ProDOS 8, High Sierra, ISO 9660 and AppleShare). You can, however, have a ProDOS partition on a hard drive that is beyond the scope of ProDOS 8 (the third or higher partition usually, or the fifth or higher partition if your SCSI card is in slot 5). Such a partition will be fully usable by GS/OS, but if it's a ProDOS partition it will not be seen by ProDOS 8 (which can only see two devices per slot, or four in slot 5 if the device is SmartPort, which the Apple II SCSI Card is). Apple's SCSI Setup programs do not currently create partitions other than partition maps or ProDOS (just like the Mac ones only create drivers, partition maps and HFS partitions). If an MS-DOS FST were available, the Finder or ADU would let you intitialize any suitable partition for MS-DOS, but I have no idea how PC Transporter would react. -- ----------------------------------------------------------------------------- Matt Deatherage, Apple Computer, Inc. | "The opinions expressed in this tome Send PERSONAL mail ONLY (please) to: | should not be construed to imply that Amer.

Well, there's no difference (at the moment) between a ProDOS 8 and a GS/OS partition, as they both use the ProDOS file system. You could, of course, keep the files and programs you use for P8 & GS/OS separated... Unless the PC-Transporter software has changed recently, I don't think that you can use an entire partition specifically as an MS-DOS partition. You can, however, create a psuedo-partition with the PC-T software, where the MS-DOS partition is actually a big ProDOS file. So, you could set up a ProDOS partition on the drive, and have an MS-DOS partition that fills said ProDOS partition. Of course, unless you put the Apple SCSI card in slot 5, you'll only be able to have 2 partitions visible when you're in ProDOS 8 - this means that you'd have to have one partition shared between the GS/OS boot volume and your P8 files/programs, and one partition for the file that's the MS-DOS partition (and then however many ProDOS filesystem partitions that are only visible to GS/OS). I believe that currently, GS/OS allows for up to 7 partitions either per SCSI card or per SCSI HD, so you could have 2 32Mb partitions for P8 (including the 1 partition for the MS-DOS stuff), and then, say, one 12Mb and one 24Mb partition that are only visible to GS/OS. The last two partition sizes really depend on what you do - I've got 3 partitions on my 64Mb drive, named :Sys, 10Mb (system partition - system software, incl. fonts, some temporary storage areas, and a few ProDOS 8 development systems), :Misc, 30Mb (for all the stuff that doesn't go on the other two :), and :Dev, 24Mb (which is where all the development stuff for the //gs goes). -- Jason Blochowiak - blochowi@garfield.cs.wisc.edu or jason@madnix.uucp "Education, like neurosis, begins at home." - Milton R.

Sapirstein You believe incorrectly. :) Under 4.0, the interim SCSI Driver could only recognize 7 partitions connected to a SCSI card. Under the 5.0 SCSI Manager, you can use up to 32 partitions on each SCSI device. -- ============================================================================ Matt Deatherage, Apple Computer, Inc. | "The opinions represented here are Developer Technical Support, Apple II | not necessarily those of Apple Group.
