I have also noticed that can be so, I donīt think itīs just the Cubase who did this. Sometimes it goes wrong when the PC should read a disk which has data saved from an Atari. I may think it could be the diskdrive or when TOS write data about the files in the directory of the disk. Format the disk in the PC again and then try again to save from Atari and read it in the PC, otherwise the disk must be damaged.
