When I try to write to a CD-RW using Nero or any other software I've tried, I've been unable to write without getting multiple read errors during the data verification process. Sure enough, the data verification process is accurate and I cannot use the CD-RW. I have two machines running Windows XP. On each of the two machines I have a drive capable of writing CD-RWs at 24x. I use Nero Burning ROM, a drive manufactured by TDK, and another manufactured by LITE ON. The CD-RWs I use are manufactured by Memorex and are capable of writing at 24x. I've also tried writing at rates as low as 8x. This problem is only with CD-RWs though. I can burn CD-Rs perfectly. And this just baffles me. I've tried using compressed air to clean out the drive of any dust with no luck. And the drivers were provided by Windows so I'm almost certain that there isn't a problem there. I should also mention that these CD-RWs are in just about perfect condition. There was a time that they even worked on my drives. But after maybe one or two burns later, I can't properly burn to them anymore. I'm just..baffled.
