'windows can't read the disk in drive'

Last night I successfully burned some files to a DVD-R in my bluray burner in my nova tech elite.

Tonight I’m trying to burn some more to another dvd-r and I’m getting the error ‘windows can’t read the disk in drive’. I cant find an option to format it but then I didn’t need to last night.

the drive is only a couple of months old
I had no problems burning last night
the disk I burned last night reads normally
I’m using blank media from the same spool as the one i burned last night and I tried 3 of them
I also tried a different brand

am I doing something stupid?
