CHAPTER 9  HARD DISK DRIVE

This window will display firmware updates that are loaded on a USB flash drive in the front 
USB port.

Firmware upgrades are available from Q-See at www.Q-See.com and may be found by 
looking up your specific model. Firmware should only be upgraded to fix a specific problem or 
add features as ongoing development may result in features being removed. 
The firmware download should be loaded onto an empty USB flash drive from the 
downloading computer and then transferred to the DVR using the front USB port.

 It is vital that the DVR be instructed to shut down using the Shut 

Down menu option prior to unplugging the device in order to avoid damaging 
the firmware or hard drive itself.

 Updating the firmware incorrectly or using the wrong update 

can permanently damage the chipset on the DVR and render it unusable. 
Updates are written to either resolve issues or add features to the DVR. If you 
are not experiencing performance issues or do not need a feature added by 

the update, we recommend not running the update.

Logging out of the DVR is recommended when there are multiple users or when physical 
access to the DVR is not restricted. Clicking on the Logoff icon will bring up a window asking 
for confirmation.
After logging off, a user can log back in by clicking on the Menu icon and entering their user 
name and password.

This is a “soft power down” of the DVR. 

NOTE! While a Macintosh computer can read and write to a drive in the 

FAT32 format, it cannot reformat a USB flash drive to that standard. We 
suggest that you use a PC to reformat your USB flash drive to FAT32 and it is 
recommended that you download firmware updates on a PC. Beginning with 
version 3.1.71, you can use the Upgrade feature in the Remote Monitoring 
software (see Section 7.9) to upgrade without a USB flash drive.

CHAPTER 7

Your DVR uses a standard SATA (Serial Advanced Technology Attachment) hard disk drive and will support 
drives up to 2TB (terabytes). These drives are the current industry standard and may be purchased 
wherever computer parts are sold. Depending on where you purchased your DVR, your hard drive may 
already be installed. But, we recognize that you may wish to upgrade or replace your drive in the future so 
this DVR is designed to make installation and replacement easy for the average user. 

It should be noted that while this is the only user-serviceable part within the case besides the battery and 
you will not void your warranty by installing or upgrading your hard disk drive, care must be taken to avoid 
damage to the other components within the case.

It is strongly advised against opening the case when atmospheric conditions present the risk of static 
discharge which can damage electronic components.

Whether installing the drive for the first time or removing the old one to install a new one, the steps are 
largely the same:

. Disconnect the DVR from the power source as well as any other connections.

. Remove screws (the number will vary depending on your model) from the side and rear of 

your DVR as indicated in 

Picture 7-1

 The DVR MUST be unplugged from all power sources as well 

as from the cameras before opening the case. Failure to do so 
can result in damage to the DVR or its components as well as 

injury or death.

. Remove the case by sliding it backwards and then lifting off.

. If removing a hard drive, you will 

need to unscrew the four drive mounting 
screws at the bottom of the DVR.
