I'm trying to back up data from a Sentinel SC21FD3044-161 21" Flat Screen CRT/DVR Combo system to a USB external hard drive. When I hit the "Copy" botton on the remote I can't tell if its backing up or not. There is not computer in the location where the system is set up so aside from taking the external HDD to a computer how can I tell when the copy is complete? The internal HDD is a 160GB drive, so how long does it take to transfer to the external? Also the external HDD is a 1.5TB drive, this shouldn't be a problem with it being the backup destination should it?
Any help you can provide would be appreciated!
