ImgBurn reports what it's told by the drive, and what your drive is saying is that it can't read the disc it has just burned a few mins before. This is usually due to a poor quality dye used when the disc was made: the dye doesn't react as expected by the burner and doesn't store the information it should. That's why we recommend testing with discs known to have high quality dyes, such as Verbatim and Taiyo Yuden blanks. This is needed to rule out an eventual problem with the burner itself, which, as any other device, also wears out.
And no, you're far from getting on my nerves
