800k vs 1.44k floppy drives

heck do i force a mac to format a floppy at 800k so that i can use it with my
apple 2gs?? do i need to cover the little hi densitity hole like on a pc??
thanks

write 800k floppies. That said, the common wisdom is that drives without the
the auto-inject feature appear to have trouble (all PowerMacs, and late model
68k Macintosh computers). Also, while you can probably trick the computer
into thinking a high density diskette is 800k by covering that hole, it is
also not advisable since data loss is probable.
Finally, on your RGB monitor issue: if the monitor says Macintosh it
probably won't work on the IIgs. As you suggested, the driving frequency is
simply too high. The RGB designator also doesn't mean anything. I have an
'AppleColour High Resolution RGB Monitor' for the Quadra, and an 'AppleColour
RGB Monitor' for the IIgs.

Any Mac with a built-in floppy drive can make 800KB disks. Well, except the
single-sided drives in the very early Macs :) I assume you've got the early
Power Mac G3.

Yes. If you're using high density disks the Mac will only let you format it
at 1.4MB. Covering the hole will fool it into thinking it's a DD disk. Be
aware though that this isn't recommended, the disk recording won't be
reliable, but it will normally work if you need to transfer some files.

cool. i will go ahead and do that. i only have boot floppys that are 5 1/4,
no 3 1/2 boot floppys and the problem is that i can't seem to format 3 1/2
floppys that are the second drive on the chain from the 5 1/4 (apple 2 gs, then
5 1/4 then 3 1/2, thats the only way i can boot since i dont' ahve 3 1/2 boot
floppys.)
so extracting the system 6.01 to covered hole floppys then booting to them,
then i should be able to make acutal formats from the apple 2 gs onto other 3
1/2 floppys??

creating the GS system disks. I had to get out my old IIsi to the disks. I
was getting an Unable To Load Prodos error with the diskettes created on my
PowerMac. The SI created fine the first time. From what I understand it is
a hardware issue that prevents the newer macs to create the diskettes.

This may be your problem: the 3.5" drive needs to be attached to the GS first, then if you have it a second 3.5", then add the two 5.25" drives. If you want to boot from the 3.5" drive, you put the floppy in the first drive attached to the cpu and for extra surety put the startup slot on the control panel to 5. If you want to boot from the 5.25" put the startup slot as 6. Doesn't matter that both types of drives are daisy chained. The order of the chain is critical.

Maybe you might have an idea on this situation. I have a IIgs
with two 3.5" drives and then my 5.25" drive. If I add in my
second 5.25", the IIgs doesn't recognize it exist. Any idea
why?

There may be some wrong with the 5.25 drive. That is the first 5.25 can not
pass the or accept the signal from the 2nd 5.25. I have seen this a few times
with 3.5 drives. A chip goes bad. I have never heard of it with a 5.25. Did you
try switching the 5.25. Put the one with the problem at the end of the chain.

Yes. I tried switching it but it still did not work. They both work
when they are daisy chained to the 3.5" drives but the second
5.25" drive won't work. I thought they were supposed to. I
even tried it with and without RAM5 drives. I tried it with and
without the RamFAST HD. Nothing seems to work. Both
drives check out in Copy II plus and both appear in good
physical working order except I can't daisy chain it. However,
I haven't tried it without the 3.5" drives.

Using Ramfast which version? How many partitions do you have on the desk
top at once? You might have one corrupt file, driver or init in your GS/OS.
These are reall apple drives and not 3rd party right? If the 5.25s work with
themselves and not with the 3.5s. Something is seems to be wrong in the system
or your 3.5s Did you try using it with out the Rmafast in place. Power down
before you do anything.
Were you at the auctions last year when ProTect was having them in Flint
for all the school districts?

No idea what you are talking about in regards to auctions in Flint.
The RamFAST is a revision C with a 3.00h ROM. The drives are
all Apple drives. There are seven partitions.

Okay this is the current testing.
RamFAST pulled and it still won't work so as suggested to me,
I swapped computers to a Woz Limited Rom 1 and still same
symptoms.
New variations: try with both 5.25 drives and one 3.5" drive
and see if it acts up. I test using one 3.5" drive and quess
what I can now see the second 5.25" drive. I test using the
second 3.5" and I can't see the second 5.25 drive. I suspect
that there is something wrong with my second 3.5" drive.
Is this possible? So it appears that I can have either two
3.5" drives and one 5.25" drive or one 3.5" drive and two
5.25" drive. Weird.

Hey William,
I have studied this problem extensively with my own Apple II system(s) and
come to the conclusion that the daisychain board is faulty in the 2nd 3.5"
drive.
To prove it (sort of) you can remove the 2nd 3.5" drive and then put your
two 5.25" drives onto your first 3.5" drive. If they both work then try
swapping out the 3.5" drive with the faulty one, and you will see that the
second 5.25" drive stops working.
I have two out of five 3.5" drives that exhibit this fault. I went as far as
swapping out the daisychain board to find the fault. Alas there is no cure
for this daisychain board as they are only found in 800K Apple 3.5" drives.
I suspect the LSI chip on it is faulty as there are very few other parts. If
the drive mechanism itself was faulty then it's an easy fix by putting in a
1.4M auto inject drive mechanism from a old Mac which are plentiful and
cheap.
A work around is to get a 5.25" controller into slot 6 to run the two 5.25"
drives and run the two 3.5" drives in the smartport. This way you can run
your 4 drives with no obvious differences except under the IIGS hood. :)

I thought about that last night. I experimented with it and found that
my second 3.5" was indeed bad.

No known cure eh?

I have a one of those old controllers in my Platinum IIe along with a
Liron card. I also have a Disk II controller.

well there you go. :)

Well how many people can fix LSI chips... none.

Well I wouldn't waste the Liron in the GS, especially to just run 5.25's,
but try out the 5.25 controller from your Platinum to see if it works. If
you have a hard drive in the GS you rarely, if ever, need two 3.5's. And
even if you don't you can set up your RAM disk to act like a 3.5 for disk
copying purposes. ie set it to 800K.

USB floppy drives don't support the 800 Ko Mac and Prodos format,
because they are based on PC floppy drives.
