Well, this error appears to me when i try to replace the old mechanic driver from the A1200 with a CF Card with 4GB.
First i thought that the errors that appear when i try to open some games (most of them AGA games) where related with the fact that i was copying the amigaos directly from windows.
After some expediencies i have notice that the errors keep appearing.
Based on this video https://www.youtube.com/watch?v=Zd42RsKHm5Y, and basically what you have to do is replace in the maxtransfer field from hd tools the data to : 0x1FE00 and hit enter.
