Hi Guys Bought a FLOUREON 1 X 8CH Security DVR +8 X Outdoor Camera HDMI USB WiFi 3G Security Kit UK off eBay. All running etc happy with it's performance for a cheapo kit, only one problem! I bought a 1TB 3.5'' SATA HDD and works fine on PC, had it formatted as NTFS and FAT32 but the DVR doesn't pick it up. Any ideas? HDD works fine on PC, might try a smaller HDD on DVR if I can find one. But thought I'd ask the experts! Thanks
