Hi everyone and thanks for the help and advices.
I found that my CF card is somehow defective.
I've trayed to repartition it and lost all data.
Now i'm breaking my head on how to partition it and format it on pc using the WinUae.
until now i've managed to "see" the drive (which is format to fat32) on HDToolBox. but when i tray to "change drive type" and scan for drive information, the information that HDToolBox manage to "read" from the card is not the correct one.
I don't know how to set it manually. i have 4G card and i don't know what is the sector size, how many "heads" and such.
Also, when i prtition it and try to save it, i get error 28... can someone help me?
