High density floppydrive on A2000?

[Oldsmobile_Mike]

What you quoted of mine was right and mechys response is irrelevant.

All right dude, somebody needs to take a chill-pill.

Also, this has gotten way off course from OP's original question, which was "can an A2000 use a high density drive?" -- I think that's been answered -- "Yes, it can, under certain conditions".  LOL.

In my defence I edited the post to make it less aggressive.

You can use pretty much any high density drive as an internal Amiga drive pretty easily, you just need to figure out where all the extra signals come from (disk change/ready etc). The problem is using high density disks, for that you need a 357A (which should have all the signals in the right place).

Much better.  It was starting to sound like some of those Facebook Amiga groups, for a minute there.  :laughing:

I did manage to swap the boards over from an actual 357A amiga high density drive on over to the 357 PC drive.  The old disk heads were worn out and was giving me trouble, but after swapping the boards, started to read great again. Still retained the ability to do 1.76MB (Or whatever the HD capacity was)

But converting a Panasonic drive on over to be used on the Amiga is pretty straightforward and easier to obtain.  As stated earlier, only as a 880K drive.

There is another option for reading HD floppies on A2000.
You can use LS120 drive with IDE controller and IDEFIX software.

It worked for me on my A2000 with Tandem IDE controller and ROM 3.1 or 2.x.

@Thomas - I thought they were spun at half the rate because of the Paula, not Agnus?

OP - AFAIK an Amiga high density floppy will be "plug-and-play" on an A2000.  Probably needs 3.1, but I think you've got that covered already.  Other companies made high density floppy drives for Amiga's back in the day (Applied Engineering comes to mind), but those drives did require a software patch and you couldn't boot off them (that's just from memory).

Edit - just googled up this thread:  http://eab.abime.net/showthread.php?t=55344   Lot of information here.

I have an Applied Engineering High Density floppy drive.  It is basically a HD mac floppy modified for use with the Amiga.  It came out in the OS 1.3 days.  Like Oldsmobile_Mike said it needs a softwave driver to use HD mode, and therefore does not autoboot in HD mode.

Unfortunately the driver does not work for OS 2.0 and above.
On the upside the drive is extremely well built and has a really nice auto-eject feature like most mac drives of the generation.

Additionally the HD mode format (only 1.52 meg formatted) is not the same as Amiga HD floppy format (1.76 meg formatted).  It is to bad that the amiga cannot be used with Amiga HD floppy Format disk, nor is there a driver for OS 2.0+.

I have a 1" Chinon HD drive that looks like it was made for the A2000 as it is the same color and also has a lower "lip" plastic piece to fill in the gap.  It works on my A2000 just fine as a HD drive.

It looks like the drive to the LEFT:

Well, I guess the next thing for me to look for is a proper Amiga floppy HD drive, amigakit says they have some stock pending but that could be months or years away. They are as rare as a reasonably priced 4000T

Change FZ-357 to 880k amiga drive - I do not know if it fit mechanically in a 2000

The guy specifically wants to be able to read PC 1.4mb disks on his A2000, there is no shortage of drives that can be used to read 880k disks.

Next time you have the A2000 open, can you check if it is an FB 357A? I know commodore said they had stocks of them at some point, but I never saw them for sale in the UK. However this is not unheard of as the dealers aimed more at the low spec machines.

Long time ago I bought a HD drive for my A500 but can't remember the make of it.

[motrucker]

I use a Chinon FZ357A in my A2000. I can't get it to work as a DF 1 in HD mode though. Not really a problem, but I wonder why?
Has anyone here tried this project?:

My a4000 hd drive worked in my 2000, also.  

I remember setting a jumper to use both drives.

I've been using a high density external floppy for a long time on my Amigas.  It's called the XL Drive made by Power Computing Ltd.
It supports Amiga disks (1.76MB) and IBM formatted disk (1.44MB), think it even supports Atari floppies but I've never tried it myself.  Requires WB2.1min. A driver is required to be setup in S-S to have the HD capacity else drive just works as normal Amiga FD.

I am using an Amiga HD floppy drive in my 2000.  Works great.
