Moon 0 Posted January 21, 2018 Hello, I just purchased 2 Toshiba ESV4 nvr's, and an ESV16 nvr. I cannot get any to format a hard drive. It see's the drive but all I get is a "formatting NaN%" indication. I have tried 3 different drives listed on the hard drive compatibility list with toshiba, no luck. any thoughts?
