Next step:
Save that file somehwere else as a means of interim storage.

Try to copy that file from that interim storage to your RealBand drive. Do you get the same error?

If not, then the error is probably caused by RealBand.
If yes, then the error is possibly a matter of how the drive has been formatted.
If yes, what is the disk format: FAT or NTFS?

Also, have you checked the drive for errors?
