Is there any maximum storage size limits for either GSOS or ProDOS 8 ? I'm considering building my own HD and I was wondering if it was worth getting an 84 meg HD. I'd be using Apple's SCSI card (revision C). Thanks for any help.

Luckily, SCSI drives can be partitioned into multiple virtual drives of smaller size. Thus, you should be able to make 2 32Mb partitions and a 20 Mb partition which will work fine (although I think ProDOS 8 only recognizes the first 2 partitions of any drive, due to the fact that not more than two drives can exist in the same slot) Now for a question: Is there any reason why a hard drive couldn't be formatted in High Sierra/ISO 9660 format from GS/OS? Does the code to write to a disk exist? Or is High Sierra for the GS limited to CD-ROM only? -- Les Barstow |Bitnet: LMB7421@RITVAX "What about the R.O.U.S's?" |UUCP: ...rutgers!rochester!ritcv!ultb!lmb7421 "The Rodents Of Unusual Size? |ARPA: lmb7421@ultb.isc.rit.edu I don't believe they exist!" - Buttercup and Wesley, _The Princess Bride_

Each file on a ProDOS volume is limited to 16Mb. You can, however, partition your hard drive into segments <= 32Mb.

The High Sierra FST does not support formatting, or any other call which would attempt to create or alter data on a volume. But this does not mean that you can't do it. I don't know of any published programs which would allow you to do this, however.

I have recently purchased the Seagate ST-296-N 85 Meg SCSI drive and an A-Hive case from Tulin. Here are some of my observations: As mentioned in previous messages, the power switch on the case is pretty lame. I have an engineering student on my staff who says he can mount a good switch on the back of the drive. I used the hard disk low level format program that is on Apple2-l. I then set up 3 partitions with the Advanced Disk Utility. The first 2 are equal sections of 32M each (the max of ProDOS). The last partition used up the final 17M-18M on the drive. All works fine except that the last partition can only be accessed by GSOS applications. When I go to ProDOS8, I only get the first 2 partitions mapped in drive 1 and 2. Here is a list of the Hardware I have and where it is in my GS: Slot 1 Printer Port Slot 2 Apple // SCSI Card Setting is Your Card (I have Mini-8 switch box on this port with: A - Appletalk box in Appletalk Network to LaserWriter+, B - Zoom Modem 2400) Slot 3-6 Normal Default Settings Slot 7 Built-in Appletalk. (I have mentioned in an earlier message that when I use the modem in Proterm 2.1 after booting GSOS 3.0, I get junk like there is a lot of line noise. If I set slot 7 to Your Card, it works fine. Also, I don't have to make this change if I boot directly to ProDOS8 instead of GSOS.) I do have one question. I'm having problems printing to the LaserWriter Plus from Appleworks GS. Sometimes I will get 1 page, other times I will get a few pages, then the program stops and says it can't print the document. I know this is happening in the Word Processor. I haven't really tried it in other programs yet. I do have a lot of Mac traffic on the network (not AppleShare) but even when there is no Macs printing, I still have the Problem. Any comments???

I have a feeling you are running into memory problems. With AppleShare,
System 5.0 takes up quite a bit more memory than 4.0. How much memory do
you have? What kind of document is it? Does it have lots of fonts,
styles or sizes? How many pages is it?

If you would convert a hard disk to HS format, then you could only access the disk from GSOS. All of your ProDOS 8 and earlier ProDOS 16 applications would be locked out from your hard disk. Sounds a little less than useful to me.

I hope that you are ready to go back to the days of using the K(runch disk files option. Unfortunately, the HS/ISO 9660 file systems store files in ranges of contiguous blocks, which is good for speed, but not for space. As far as the filename length, you are limited to 32 characters under HS/ISO. About the upper-case-and-numbers-only format of ProDOS: ProDOS *does* support upper/lower case now, and HS/ISO only support upper case. Also, HS/ISO both limit subdirectories to eight levels of nesting, ProDOS doesn't. There are also *numerous* structures in the HS/ISO volumes which would need to be updated constantly.
