I recently purchased and installed a Clover Electronics Surveillance system for my business. This has an internal 500 GB hard drive. One of the ways that I can view the information that it is saving is to copy it to a USB which seems to work OK using a USB stick. But I can’t put much on one, so I ordered a Western Digital My Book Essential 500 GB external drive. The system will not recognize it. I tried the WD on my laptop and desktop – it seems to work perfectly on there – so believe it is something with the Clover system. I called Clover support, they had no idea why it wasn’t working, said it should work as soon as I plugged it in – but of course it doesn’t. His only thought was maybe because the HD was the newest model. Anyone had any experience with this type of problem?
