#High Density Floppy Driv
19 messages in this thread
Hi,
I recently installed a Commodore high density floppy drive and ADOS 2.1 in my
A3000. The system still has the old low density floppy, too. Can anyone answer
these questions?…
1. Which floppy should get the section of ribbon cable with the "twist?" (In
case it matters, I'm installing AMAX IV also).
2. Why is only DF0: recognized when I boot? Is there something I must add to
the MountList or StartupSequence?
3. Do I *really* still need the old low density drive? I've heard it said that
the high density one is "unreliable" on low density disks.
4. Does the Cross-DOS included in WB2.1 allow access to high density MS-DOS
formatted disks? If so, is there anything I need to do to make it happen?
Thanks in advance for any help!

Brian,
I put HiD drive in my A3000 and pitched the original floppy drive. To me,
the internal space was far more valuable… I have a second hard drive in
there. I've never had a problem reading any disk at all with the HiD
floppy, (that means 72&1.4 msdos – mac HiD, mac LD, Ami HiD & LD) and up
until last week I had AMAX II+ in there (but that's just been replaced by
Emplant).
Hi, Michael,
Thanks for responding to question #3 about keeping the LoD floppy drive. I
figured out that I needed to change the Berg pin on one of the drives to DF1
and now I can use it, but the high density drive does not want to format a HiD
floppy to high density (says it will make it 720K).
My *biggest* problem is that I could not find the complete ADOS 2.1 upgrade kit
and have disks but no documentation. (I bought, from a mail order place which
advertises in an Amiga magazine, a set of 2.1 disks which don't have official
looking labels. I could not find a set from Commodore with docs anywhere.)
Therefore my questions: how do I tell it to format to high density? How do I
tell it to do an Amiga format rather than an MS-DOS format (and vice-versa)?
>> I had AMAX II+ in there (but that's just been replaced by Emplant).
Any comments on why you went with Emplant rather than upgrading your AMAX? And
what do you thing of Emplant?
Thanks,
Brian
Brian,
I think that in order to be able to use the HD drive with HD format you
need at least KickStart 2.04 (= v37.175). As you have an A3000, I suspect
you might still have a pre-37 KickStart on it (i.e. v36.x), in that case
you should try to get your hands on a new KS…
BTW… 4) Yes, you can! No, you don't have to do anything special.

Hi, Christian,
I have kickstart 37.175 and Workbench 38.36 (I just installed ADOS 2.1). Should
everything happen automatically doing anything special?
By the way, how does one find out which numbers (like 37.175) represent which
software release (like 2.04)?? (Aside from getting it from Germany 😉
Thanks for help from across "the big pond."
Brian,
have a look into your Devs/DOSDrivers drawer. There should be an icon
for "Pipe" in it. To use your floppy with MS-DOS format you need a "PCx"
as well ("x" being the unit, like in df0:, df1:, etc.). If it's not
already there, you will find a "PC0" and a "PC1" in your
Storage/DOSDrivers drawer. Just copy the file(s) you need to your
Devs/DOSDrivers drawer and double-click on it/them which will mount the
respective drives as MS-DOS format. From now on this will be done
automatically when booting until you remove the files again from the dir.
Apart from that, in your Tools/Commodities drawer, you'll find CrossDOS,
which lets you alter the "Text Filtering" and "Text Translation" settings
(read your manual what they do respectively – I just left'em like they
were…).
Sorry, I just had a quick browse though MY manuals and it only says
"720KB", so I think you may have to create some modified "Mountlist"
entries to cater for the MS-DOS HD format…

Thanks, Chris,
I found the *finally* found the necessary files and put them in the right place
to have access to MS-DOS floppies. Thanks for the help.
Best regards,
Brian
Brian,
>>how do I tell it to format to high density?<<
You shouldn't have to. If you insert a HiD floppy the system should format
it as a HiD disk. Since installing the drive, other than the test I did to
see if it would work, I don't think I've ever bothered to format an Amiga
floppy disk… everything is either on my hard drive, a tape back up, or
gets written to HiDensity MSDOS or MAC disks! Who uses Amiga floppy disks?
<ducking>
Look in your Devs:Dosdrivers drawer. You should have a driver (and icon)
for PC0 which is the dos driver for crossdos. If it's not there, look on
your utilities or extras disk. I believe that these have to be installed
manually when you do the upgrade to 2.1. I'm not certain though, as I
still use 2.04 and the commercial version of CrosDos (v5).
>>Any comments on why you went with Emplant rather than upgrading
your AMAX?<<
Lots.
I've been a ReadySoft customer for years… going from A-Max to A-Max II
to A-Max II+… I waited patiently for each upgrade. I waited even as the
announced release dates came and went. I waited for new features. I waited
for online support. While they always answered their phones and eventually
addressed any problems I had, it was time consuming and frustrating, often
requiring me to write or call several times. Faxes went unanswered.
The all of a sudden some company announced that they would have a new
Emulator on the market that would not only do MAC in the Amiga, but do it
in color. And that their product would multitask. And their product would
run emulations other than DOS. Utilities Unlimited seemed to be promising
everything under the sun, and more. I couldn't wait to see what they came
out with becasue it sounded so implausible.
Then they went and did it. The first boards shipped with the usual amount
of bugs in the software that can be expected in a new product of this
type… but more importantly, users like Jonathan Blackwell started
reporting that the Emplant actually worked. And maybe even _more_
importantly, he reported getting software updates on what seems like a
weekly basis, directly from UU's BBS. Jim Drew was determined to get this
thing right, and do right by his customers.
Jim appeared out of nowhere and started personally assisting people in the
online community here on CIS, (and elsewhere, which I could live without
<g>). That did it.
With a product as complex and powerful as this, I wanted the support I
deserved when I needed it. I don't know how long ReadySoft was working on
support for color, but it sure seemed to me like the possibility of rael
competition is what made them finally concede and put their act in to high
gear for A-Max IV.
It was too late for me… I had already decided that if a company like UU
was going to support both the Amiga and their users the way they were, I
wanted to be using their products.
>>And what do you thin[k] of Emplant?<<
I'm astounded by the technology and impressed with both the functionality
and support provided by UU… I've only just installed Emplant and I can
say that I am incredibly impressed. This board is designed to address the
needs of using an Amiga in a world that speaks everything _but_ Amiga.
It's felxibility will keep my Amiga useful far longer than any other Amiga
specific peripheral I might own.

Hi, Michael,
I have managed to format Amiga low and high density disks now. I've been able
to read a low density MS-DOS disk in the high density drive, but a high density
one shows up with garbage as file names/dirs. It appears that my
MS-DOS compatibilities are coming from Multi-DOS rather than Cross-DOS.
(I gave up on Consultron a couple of years ago when MultiDOS came along and
CrossDOS was being done for CBM rather than for me.) MultiDOS is not set up to
read/write HiD disks (at least the version I have.)
I will attempt the manual install as you suggest. Thanks for that input.
Regarding ReadySoft, I have called a twice this week asking for information on
how to hook up the floppy drives and have not gotten an answer. I understand
your loss of confidence as I am beginning to question my decision to go with
AMAX IV. The biggest reason I did it was because I didn't want to scrounge
around for 256K Mac ROMs…I already had the 128Ks. Thanks for the detailed
information on Emplant and the customer support. I wish them great success.
Best regards,
Brian
Hi again Michael,
I *finally* found the files you mentioned. I put both PC0 and PC1 into the
proper drawer and both floppies (LoD & HiD) worked after a reboot. Thanks loads
for the help. Now for one last question (today anyway):
Since I installed the AMAX IV and ADOS 2.1 my power and hard drive LEDs have
stopped working (the ones on the front of the A3000). Any idea why and what I
can do to get them back?
Best regards,
Brian

Brian,
That's a new one on me. Sorry, I've no idea what's going on.
Maybe Mark Manes has run in to this… Mark?
Brian,
looks like a "pulled plug from socket – will not work" situation. I
don't know about the A3000, but in my A2000 the LED's wires lead to some
pins on the motherboard (power) or hard drive (HD) respectively, so you
might have just pulled them whilst fitting your new boards…

Hi, again, Chris,
>> looks like a "pulled plug from socket – will not work" situation.<<
I'm a "hardware" guy and that's the first thing I checked. However, I'll look
again next time I open the case.
Brian
Check to see if the plug has been inverted. As the LED is a Diode it will
only work one way.
Did this several times myself.
Roy
>> Check to see if the plug has been inverted. <<
I don't believe the LEDs were ever disconnected, but I'll double check. Thanks.
Brian
Brian,
Check the wire lead that connects the LED to the motherboard and make sure that
is secure. I have also had one machine that had a cold solder joint on one of
the LED connections that came free after several cycles of opening up the
machine to add cards.

There's a hard to find culprit! I'll check it the next time I open the case.
Thanks.

You have to have the HiD floppy as DF0… (There is a patch to use it as
DF1, but I'd suggest moving the drive to DF0 anyway.)
As to your third question, I've never had any trouble reading and writing
low density diskettes with my HiD drive. (PC's have this problem, not
Amiga's)

Hi, Bob,
Thanks for the help. I'll move the HiD to DF0.
