Physical Formatting for MO Disks
The Format function accessed via the front panel [FORMAT] button is all that is
required to prepare new MO disks and MO disks that have been used to store other
kinds of data for use with the D24. This is a logical, or high-level format, which simply
readies the disk for storing D24 data, and takes only a few seconds.
In addition to the logical format function, a physical format function for use with exter-
nal disk drives and damaged MO disks is also available. An MO disk may become dam-
aged when, for example, the D24 is turned off while recording. If the D24 displays a
Drive or Media error, which cannot be remedied by cleaning the MO disk (see “Error
Messages” on page 194), the Physical Format function can be used to reinitialize the
disk. As with the logical formatting function, physical formatting permanently erases
all data on the disk. A physical format, also known as a low-level format, rewrites all the
sector addresses on the disk, and can take several minutes.
1 Insert the damaged MO disk into the D24 disk drive.
To perform a physical format on an MO disk inserted in an external MO disk drive, use
the Drive Select function to select the disk drive. See “Selecting the Work Disk” on
page 161.
2 Press the [UTILITY] button.
The UTILITY indicator lights up.
3 Use the JOG/DATA dial to select PHYS FORMAT, and then press the [ENTER]
button.
The FORMAT indicator flashes and “ARE YOU SURE” flashes on the display.
4 Press the [ENTER] button again to conrm your selection, or the [CANCEL]
button to cancel the Physical Format function.
The physical formatting process starts and “FORMATTING” appears on the display.
When the physical formatting process is complete, “FINISHED” appears on the display
and the FORMAT indicator goes out.
The MO disk is now ready for use.
If the D24 displays a media error message even after running the Physical Format func-
tion, the MO disk may be damaged beyond repair.
MO disks formatted using the Physical Format function do not need to be formatted
using the front panel [FORMAT] function.
