Limitations

Not support quarter track

When copy to .nib file use disk copy, the copy program will rewrite the entire track. After copy, the sync bytes are reserved which is not the same as the standard .nib file. In this case other apple emulators or floppy emulators may not able to recognize this file.

Write to woz file will not alter the meta data. As the meta data carry the checksum, the image after write may not use by other system unless it was patched to fix the checksum or the system does not care about the checksum like wDrive.

Write operation is timing critical. The write speed of the SD card greatly affect the success of write to disk. It is better to verify the disk use disk tools. For copy disk case, just copy the bad sector/track again.
