Flash ROM Fragmentation

When the MPC2000XL writes data to the flash ROM, it writes consecutively in the available area.
However, when flash ROM data is deleted, empty spaces develop between the data unless the
data is written in the last available space. Wave pattern data which is saved to the flash ROM is
directly generated, and always needs to be one link of data. In this case, the MPC2000XL will not
write to an area if the area is too small for the wave pattern data and will write in another available
space. Therefore, there may be cases when wave pattern data cannot be saved to the flash ROM
even if the total available space is larger than the data size of the wave pattern. This type of
available disk space sandwiched between data appears on the Frag'd= field of the Save
screen. The MPC2000XL can organize data allocation and increase the available consecutive
disk space. Select F-ROM in the Device: field of each Disk mode screen and press OPEN
WINDOW.
