Very weird problem
Out of all the Amiga problems I have troubled you with in the past, this must be the weirdest one of all. I really have no idea why this is happening. Although it is not really WHDLoad related, perhaps the WHDLoad errors I am getting will help us understand what is going on.
I have an Amiga 1200 with 10MBs RAM, and I recently acquired a 3.2GB hard disk. I was finally able to add a massive amount of WHDLoad games in my disk, and everything was working fine. However, as I was left with very little space I decided to use a 4GB disk instead. So I mounted them both on a PC and used WinUAE to copy everything from the smaller disk to the bigger one. The 4GB disk is now connected to my Amiga and most things appear to be working fine. However, several of the games that work in the old disk (and the identical WinUAE setup that I have) refuse to work in the new one, and I can't for the life of me understand why as both disks contain the exact same files and they were even copied in a proper Amiga environment (Directory Opus to be exact)! Here are some games that work fine in the smaller disk and return errors in the bigger one: Code:
Fightin' Spirit Exception "Illegal Instruction" ($10) at $2808 occured. Fightin' Spirit AGA error dyring 'resload_LoadKick' invalid kickstart image Dangerous Streets AGA Exception "Illegal Instruction" ($10) at $1FFFC$ (Task 'exec.library') occured. The only thing I can think of is that some files were copied as read only and need to be unprotected - but which ones? I checked the kickstart files and they are unprotected. I repeat that the exact same files -all 3GB+ of them- exist in the other hard disk and the games run without any problems. Any help will be appreciated. |

Wow, I really managed to stump you with this one, didn't I? So no ideas at all as to why this may be happening?

Open hdtoolbox, select first partition, find max transfer value somewhere in hdtoolbox settings, make sure value is 0x1fe00 (or less), remember to press return after changing it, do the same for all partitions. save changes. Some files might be damaged and need to be copied again.
Very common problem. |

Uh, one more question: any idea where HDToolbox saves that information? I wouldn't want to overwrite that file when copying all the files back to the hard disk.

It's stored in the partition table. You cannot overwrite it by copying files or even formatting partitions. Only HDToolbox and similar programs can change it.

It did the trick. Thank you so much, Toni and Thomas.

Is the maxtransfer problem only related to internal IDE of the A1200? Would this problem also apply to Idefix + PFS3 combination?

The IDEfix readme says that you won't have any MaxTransfer problem with it, so probably it does not apply.

What about BlizzardPPC scsi? Sometimes i get these kind of WHDLoad-errors also and i could rule out the maxtransfer error setting it to a lower value. Does it have an effect on file read/write speed if i set 0x1fe00 maxtransfer?

Thanks to everyone who pointed me to this, I will try out tonight if my WHDLoad games load with this changed. I only get the kickstart error though, not the others.
