Chapter 11: LDVR-3U Installation Procedures
Before powering up the unit for the first time, it is highly recommended that you
re-seat each hard drive. Perform the following to each drive WHILE THE 3U IS
POWERED OFF: unlock the drive, pull it out, gently but firmly push it back in
until it does not go back any further, re-lock the drive. This prevents system
startup problems and random intermittent drive errors due to EIDE data
connectors working themselves loose inside the drive bays and causing faulty
connections.
When replacing or upgrading hard drive(s) in LDVR-3U, all the hard drives must
be the same size. The same make and model of hard drives is also highly
recommended.
Procedures
You may need to reconfigure the RAID controller board BIOS when you replace
a bad hard drive, if you forget to update the 3DM Windows utility before
physically removing the bad drive. Refer to the “Quick Switch One Hard Drive”
section of this manual for detailed instructions.
Remove Hard Drive Volume(s) from LDVR-SP Storage
The Multi Volume Configuration application is used to temporarily remove hard
drives that are being worked on (upgraded or replaced). This procedure is
necessary so that the LDVR-3U firmware does not try to record video on the hard
drives when the recorder is started.
