Here's how to format the MR-1's hard disk.

*You should only perform this operation if you want to erase all of the data saved on the hard disk, or if the message "Drive Error." appears frequently.*

All data will be erased from the hard disk when you execute this operation, so you should use it with caution.Before executing this operation, you should make a backup of any data you want to keep.

(Info on how to back up your files are on p.42 of the manual, "Using the MR-1 with your computer")

If a power failure or similar accident occurs during formatting, the MR-1 may become inoperable.If this occurs, please contact Korg customer service.
