Issue

The DX4700HD/DX4800HD fails to record video on startup.

Product Line

Pelco Video Management

Environment

  • DX4700HD
  • DX4800HD

Cause

  • The DX4700HD/DX4800HD is not properly recording video due to a formatting problem.
  • Under system info, the drive partition info is listed as = Not Formatted.
  • DX4700_DX4800 displays "Found New HDD" after boot up.

Resolution

The DX4700HD/DX4800HD by default is set for No Partition, this record mode will record all video however Pelco recommends setting the Event Partition.

The DX4700HD/DX4800HD supports internal HDD and external eSATA media storage. The unit allows you to combine internal and external media to create one large storage system, use only internal media for storage, or use only external media for storage.

NOTE: Before you use an eSATA device as a primary or extended external storage device, read the section titled eSATA Storage on page 45.

You can configure how internal hard disk storage is allocated for storing recorded video. The HVR 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 OFF. The remaining storage capacity is allocated to the Normal Partition (Normal folder).

WARNING: Before you use the DX4700HD/DX4800HD to record video, read the HDD Partition Notification (refer to Figure 38). 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.

The unit allows you to configure the following settings:

  • 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 OFF. When the partitions are full, the unit will record over previously recorded data.
     
  • Auto Delete: Allows you to configure when the HVR automatically deletes all data (OFF, 1 DAY, 2 DAYS, 5 DAYS, 10 DAYS, 20 DAYS, 30 DAYS, 40 DAYS, 50 DAYS, or 60 DAYS). The default setting is OFF.
     
  • 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 OFF. This option cannot be configured remotely using the DX Series client.
     
  • Disable Internal HDD: Displays a warning message when clicked, prompting for approval to restart the unit. If the unit is restarted, recorded video storage to the internal HDDs (primary storage) is disabled.
     
  • Storage:
    • ALL: Primary (internal) storage can consist of internal HDDs and an external eSATA media. Video data is recorded first to INTERNAL 1 (HDD connected to the SATA 1 connector). Once INTERNAL 1 is filled, data is recorded to INTERNAL 2, and so forth, until all of the internal HDDs are filled. After the internal media is filled, video is recorded to the EXTERNAL 1 media. The unit can be configured to recognize only the eSATA media as stand-alone primary storage.
    • INTERNAL 1 to 4: HDD media connected to SATA connector 1 to 4 on the motherboard.
    • EXTERNAL 1: The eSATA device is configured as extended storage media.
       
  • Serial Number: Serial number of the media displayed in the Storage box.
     
  • Format: Allows you to format all of the HDDs that make up the internal storage system. “ALL” must be displayed in the Storage box to format the internal storage.
     
  • Insert: Allows you to insert (configure) an eSATA device as external media.
     
  • Eject: Allows you to eject an eSATA device. For more information about the eject feature, refer to eSATA Storage on page 45.

A different formatting process is required when installing a new HDD or connecting an eSATA device to be used as extended storage. The system only formats the newly installed HDD or eSATA device; the current drives are not reformatted. Refer to the DX4700HD/DX4800HD Series HDD/DVD Drive Installation manual for information about installing an HDD.

Formatting Primary Storage Media:
The unit allows only the primary storage system to be reformatted. Individual internal drives or external storage media cannot be reformatted separately.

To format the primary storage media:

  1. From the Camera menu, click Storage. The Storage properties appear. The default Storage setting is ALL, and the Format button is available.
    NOTE: The unit will not allow an INTERNAL 1 to 4 or EXTERNAL 1 device to be formatted: the Format button is unavailable if any of these settings are selected in the Storage box.
  2. Click Format. The on-screen keyboard appears.
  3. Type Yes to format the HDD.
  4. Click OK.
  5. Wait while the system drives are formatted. After the format process is complete, the “Restart the System” dialog box appears.
  6. Click OK. The unit restarts.


To set the Event Partition:

  1. Go to Event Partition.
  2. Select No Partition, select percentage of Event Recording to match desired schedule.
  3. Select the X (top right) to Exit.
  4. Warning message will appear do you want to format hard drive.
  5. Select OK.
  6. Format process will complete and restart system.
