Ok, found something interesting. If I put the programs that don't run in my work partition they work fine but if they ar in any other partition they give me the error.
Thoughts?
Could be a MaxTransfer problem. The ProTracker executable is bigger than 128K. If you try to load it from a partition with MaxTransfer > 128K on the internal IDE bus, the file is corrupted and cannot be loaded as a program.
Files are also currupted during write, so after correcting MaxTransfer you have to copy all files bigger than 128K again.
