Operational Mode Information
Synchronizes management data
to media, immediately after
completion of writing files
Saves finished files, even if an error occurs halfway through the
recording.
Note
“File System” operation mode: ON – Default setting Even in the
event of a drive power interruption or a failure in recording a
file, previously finished files are safely stored. Next time the
volume is mounted, only the damaged file during recording due
to such interruptions is deleted, while the other completed files
are recovered automatically. This is because system information
is updated and written every time a new file is recorded. It is
recommended to set to [ON], when safety comes on top of your
priorities.
“File System” operation mode: OFF The [OFF] mode provides
improved performance in recording a series of small files. In
addition, it enhances the efficiency rate of cartridge usage. On the
other hand, many files could possibly be deleted due to troubles
such as a power interruption during successive recordings. This
is because system information is updated and written once, right
after consecutive files are recorded. In the case of a recording
trouble, a rollback occurs and it returns to the previous state
before you start recording a series of files. Next time the volume
is mounted, the last complete file system update written to the
cartridge is valid. All previous small files unaccompanied by
complete file system records will be deleted and irrecoverable.
For this reason, it is recommended to set to [ON] under unstable
power supply environments.
Default Volume Type
Optical Disc Archive 1 :
When unformatted media is injected, it will be automatically
formatted to this volume type.
Always write with parity-added in the Optical Disc Archive 2
media. The maximum number of files is 480000.
Note
When parity-added write is performed, broken files will be
recovered/restored since performing “Recover File” corrects the
error with parity information.
