I recently purchased Dual Layer R+ DVDs (Memorex) so that I can perform a full backup of a system. But unfortunately, the backup fails with Windows 7 complaining that it could not verify the disc and there was some write error. Here are the details of my system: 1. Win 7 Home Premium 2. Dell Inspiron 1764 - hl-dt-st dvd+-rw gt32n (DVD DL Writer) 3. Trying to create a System Image using DVDs I need to resolve this urgently as I am shipping this laptop to my sister and shes very naive when it comes to computers. I figured a restore DVD + System Image would be the easiest for her to "format and reinstall" everything. Plus she doesn't need to bother about activation and other crap.
Try to burn your images at slow speed or you could try acronis trueimage to make recovery dvd's or hidden recovery partition.
Memorex is a pretty good brand and i've used it quite a number of times. Maybe you could try a different brand perhaps. Also, try and burn at a slower rate - 2.4x - 4x or as low as possible.
