HARD DISK STORAGE ALLOCATION SETUP

The unit allows you to configure how internal hard disk storage is allocated for storing recorded video. The DVR combines the storage space of multiple HDDs into one logical disk and creates two partitions: TEMP and DATA. The system allocates 6 GB of disk space to the TEMP partition; the remaining space is allocated to the DATA partition. When the HDDs are formatted, the system creates two folders (Normal and Event) based on the Event Partition settings. A percentage of space is allocated to the Event Partition (event folder); the default setting is 50 percent. The remaining storage capacity is allocated to the Normal Partition (Normal folder).

NOTE: Before you use the DX4104 to record video, read the HDD Partition Notification (see below). If the Event Partition setting is changed, the system reformats all drives and re-allocates space to the Normal and Event folders based on the new event partition percentage.

  • Format: Initializes all installed HDDs. The System Information dialog box lists the installed drives and their respective capacities. If you install a new drive, the system prompts you to format the drive. When you format the drive, all data on the drive is erased.
  • Overwrite:
    • ALL: When the normal and event partitions are full, the system will begin overwriting recorded video. The oldest recorded data is overwritten first. The default setting is ALL.
    • NORMAL PARTITION: When the normal partition is full, the system will begin overwriting recorded video in the normal partition. The oldest recorded data is overwritten first.
    • EVENT PARTITION: When the event partition is full, the system will begin overwriting recorded video in the event partition. The oldest recorded data is overwritten first.
    • OFF: Protects all partitions from being overwritten. When the partitions are full, the unit stops recording.
  • Full Warning: Displays a warning message when the HDD has reached the configured percentage (size) capacity. The default setting is 70 percent. When the partitions are full, the unit stops recording.
  • Event Partition: Specifies the percentage (size) of the total hard disk space allocated for event-related recorded video. The remaining disk space is allocated for storing instant recorded video and continuous recorded video. The default setting is 50 percent.
  • Auto Delete: Allows you to configure when the DVR automatically deletes all data (OFF, 1 DAY, 2 DAYS, 5 DAYS, 10 DAYS, 20 DAYS, 30 DAYS, 40 DAYS, 50 DAYS, 60 DAYS). The default setting is OFF.

 

Formatting the System Drives

NOTES:

  • A different formatting process is required when installing a new HDD. Refer to the DX4104 Hard Drive Installation manual for more information.
  • The default setting is ALL. The Settings box can be accessed, but it cannot be changed. If a new drive is installed, the system only formats the newly installed drive; the current drives are not reformatted.

To format the system drives:

  1. From the System menu, click Hard Disk.
  2. Click Format, and then click OK.
  3. Wait while the system drives are formatted. After the format process is complete, the "Restart the System" dialog box appears.
  4. Click OK.

To customize the HDD settings:

  1. From the System menu, click Hard Disk.
  2. Click a settings box, and then select a setting.
  3. Click Close.
