Title: Speaking of IDE
Post by: Fester on December 29, 2006, 09:28:25 PM
Hi,

I have a Data Flyer Plus at home that I'm going to fit in my A2000.

As far as I know, that would work, but does anybody know how large an IDE hard drive I can put on an Amiga 2000?

Kickstart 3.1 ROMS installed.

You can put a drive of any size in there.  But I believe you're going to be limited to 4gb partitions.

That's really good to know. Thanks. I have several spare IDE drives, so all I need now is to get a flat cable and I can test my Data Flyer Plus.

Thanks for the information.

Actually one cannot tell from the information in this thread what the size limits are.

Generally every Kickstart up to version 3.1 has a limit of 4GB for *drives*. This means you *cannot* create multiple partions of 4GB each (like the previous poster suggests). Instad all partitions have to fit into the first 4GB of the drive and the rest of the drive cannot be used. If you create partitions outside of the first 4GB of the drive (which is perfectly possible), then you risk total data loss sooner or later.

Additionally to that, the size limit for HDDs does not depend on the Kickstart version, but on the version of the controller's firmware. I looked up the controller at hardware.amigafuture.de, but it does not say anything about the driver. As with any of those old controllers you should be prepared to have a limit which is even smaller than 4GB or you need a firmware update in order to use larger HDDs.

On the other hand, if the controller supports any kind of 64 bit commands and you have a fllesystem which supports these commands, too, then you can use HDDs of any size and partitions of any size even with Kickstart 2.0 and below.

Bye,
Thomas

IIRC, I had almost none problems using 9Gb IDE HDD on Tandem, A2000, KS3.1, PFS3ds

This thread has got me confused.I was told that HDDs upto a maximum of 4GBs and partitions could be no more than 2GBs.This thread seems to confuse rather than help.

That's the case for an "out-of-the-box" system using a completely barebones install of 3.1 with its default version of FFS. With the appropriate patches, those limits no longer apply. You need a patch to scsi.device and a patch to FastFileSystem. Later versions of AmigaOS have these improvements built in.

So the HDD to which you install the Workbench to has to be 4GB and upto 2GB partitions and if you upgrade to Workbench 3.5 or 3.9 any other HDDs can be as big as you like and any size partitions?

Hi Guys and Gals,

Well thanks for trying to answer my question, but my Amiga knowledge is very limited. I feel like my IQ buffer just ran out of juice. :-)

I have an Amiga 2000 with 3.1 ROMS installed. I'm running OS 3.1.

I have a Data Flyer Plus card which allows, according to the Big Book of Amiga hardware, to use SCSI or IDE devices. So I intend to install the board soon.

Problem is, I don't know if it will run my old 40GB hard drives correctly...

So what I understood from this thread is that there is a size limitation.

I could perhaps just try a IDE compact flash device but it would be nice to know if the Data Flyer works first...

Happy new year fellow Amigans!

Mr. Adams

OOOps confused Data Flyer with Power Flyer. Have looked up the exact card now. I wouldn`t get my hope too high with that piece of stoneagehardware from the time Kick 1.3 was state of the art and WB 2.x just on the horizon.
