aliciac 0 Posted March 28, 2014 Hi everyone! I have a CPCam CPD505 system. I am trying to backup to USB, but get the following error message: WARNING USB ERROR The system seems to recognise that a USB drive is connected, otherwise it gives another message, but will not backup to USB. I am using a SanDisk Cruzer Blade 4GB USB drive, full formatted as FAT32 (not NTFS). Please can someone tell me if there is only a limited number of USB drives this system works with? Thanks very much, Alicia. Share this post Link to post Share on other sites
