This message will appear when you enter record-ready mode if there is a possibility that the "Disk is too busy." This error might occur during recording because of insufficient contiguous free
space on the hard disk. Normally, a minimum of ten minutes of contiguous free space will be allocated if there is ten minutes or more free capacity; if there is less than ten minutes of free capacity, as much as exists will be allocated.

It is not necessarily the case that the "Disk too busy." error will always occur if this warning appears, but we recommend that you take the following actions.
•Back up your important files, format the hard disk, and then restore your files back onto the hard disk.
•Alternatively, delete unneeded files to increase the amount of free space, and then connect the MR-1000 to your computer in USB mode and optimize the drive. It is effective to use software of a type that optimizes the free space.
