V1200 IDE Problems

I have some problems using the IDE controller on my V1200. Maybe I’m missing something, but I can’t think of what that would be. I have tried several different Compact Flash cards together with several different adapters. They all work fine on the internal IDE controller of the A1200, but when plugging them into the V1200 IDE controller I experience problems.

The problems I experience are that for some CF cards, I am able to partition and format it and also write to it, but as soon as I try to read anything from it (like booting workbench) I receive random errors and crashes. For some other CF cards I am able to partition/format write and read some smaller files, but when trying to start bigger programs from the disk they randomly crash upon start. Sysinfo is also unable to run the speed tests on the drive when it is running from V1200 IDE, it crashes the system.

I have tried the above with two different Amiga OS installations, (OS 3.2 and OS 3.2.1), in all cases I have had the correct ROM flashed to the Vampire.

I have tried my V1200 on two different A1200 motherboards, 2B and 1D.4 (both recapped) and the problems I encounter are the same

I have also tried running the V1200 IDE controller at different speeds using the vcontrol command, I still experience the same problems

I have tried both using the latest core (2.15 Gold) aswell as the one that was shipped with the V1200 (2.13). The problems I experience are the same

The V1200 with OS 3.2.1 (and OS 3.2) works really great when I use the internal IDE connector on my A1200. I find no other problems with the V1200 card, except for the internal IDE controller.

Am I missing something very simple?

Do you also have the problems with Coffin?

When did you buy the V1200?

No, I have not tried Coffin.

I bought the V1200 in February 2021 through the waiting list

I would as first try Coffin 60.
To rule out software issues of your install

So you have the same problems since Feb/2021?
Why do you ask only 1.5 years later?

Alright, I might have to try Coffin then

As to why I ask 1.5 years later? Well, there is something called life that happens and gets in the way of hobbies for some people. Not everyone gets the luxury of doing their hobbies 24/7.

I'm fully aware that any warranties might have expired. I am just trying to figure out if it's solvable or not now that I have the time.

I think you should rule out software problems first.
Maybe your install is screwed?
Maybe the MAX-transfer setting is wrongly configured?

My question about why problems after 18month, was not about warranty - but was aimed for Why now? Why not before? What did you change? Did you reinstall the OS.. etc?

When I first used the V1200 I didn't use the V1200 IDE Controller, but instead used the internal IDE controller. I have only recently  started trying using the V1200 IDE controller.

The CF cards I have used have always been partitioned and formatted right after I have inserted them in the V1200 IDE Controller, so I have always started from "scratch" so to speak, using HD Toolbox that was included in the Amiga OS 3.2 installation disks.

I have only relied on the standard parameters that are found by HD Toolbox and haven't tried to tweak the MAX-transfer settings or anything like that.

Are there any document/links to where there is possible to read more on possible settings that I can try here? Any guidelines for what kind of values are reasonable?

Make sure to set MaxTransfer to 0x1fe00

Same thing happened to me, mine was left in its box for well over a year because no time or space to dedicate to the project. Its on hiatus again for me.

Thanks! Setting MaxTransfer to 0x1fe00 for every partition seems to have solved the problems I was having
