I’ve got a LH-18A1P bought about 2-3 months ago and it was working fine. I haven’t had the need to use it for the last 6 weeks, so it’s been idle.
I needed to burn something on the weekend, fired up Nero and as usual turned on data verification after burning. The first burn was bad, data verification failed. Never happened before, so I thought it was a fluke. Burned another, also bad. That night I burned 4 DVDs and all were bad. The 4 burns were at 12x, 8x, 8x, 12x.
Is this a problem with the media (I’m using Verbatim), the burner or the software? If it’s the burner, then I’ll return for exchange under warranty.
