I received this error after doing this: Create Backup Wizard - Entire disk - HDD c: - archive location: d:\mybackup.tib (I'm using a LITE-ON DVDRW SHW-160P6S PS01) -new Full backup -these options: Compression Level = None; All Media Components checked; the rest I left at default. I left the DVD tray open until prompted by TI to insert media. The media I inserted was a Memorex dual layer DVD+R disc which was previously formatted using Nero InCD. I clicked proceed and watched the green progress bar fill up 25% then the poor media error showed up. Granted, I had the 'Enable CD recording on this drive' checked under the drive's Properties. I really don't like the idea of wasting $3 to burn another beer mat (dual layer DVDs are expensive and I have only 9 left). I'm running WinXP Pro SP2 and all current SP3 hotfixes. Here is my burner: http://www.liteonamericas.com/us/DVDRW_1673S.htm . The Memorex D/L DVD+Rs are here: http://www.compusa.com/products/product_info.asp?product_code=337562&pfp=cat3 . Maybe I'm doing something wrong. Maybe there's some arcane or obvious tweak I'm missing. Dunno. Any ideas? Really appreciate any/all input as I have 9 more trys(discs) before I quit.
