Hello tks1234 Personally I can report my experience: I used Memorex long time ago and one day my PC won't to boot at all. At the beginning I was becoming crazy to looking for the problem, and at the end I discovered that booting the computer with a Memorex CD into the drive, it locks the computer. It was not a bad bootable CD, just a CD with any data stored, infact leaving any other media in the drive, of any other manufacter except Memorex, I didn't have any more problems. After that experience I spend some cent more and I started to buy only better media like Verbatim AZO, from that time I forgot what mean have problems with the media. Another step to consider is to looking for a new firmware for your media burner, sometimes it fix the issue, but if your drive is so old the a new firmware is no longer avaiable, you can consider to buy a more recent drive
