Hi all I wonder if anyone can help or whether anyone is suffering the same fate? [bold]Problem:[/bold] Trying to write files from HDD (nothing special, photos and a backup of My Documents). [bold]Config:[/bold] Prim Master = 40Gb HDD Prim Slave = 60Gb HDD Sec Master = Memorex DVD-Reader Sec Slave = Sony 510 DVD-RW Athlon 1600XP 512Mb Plently of free space etc. [bold]Software:[/bold] Nero 6 I have tried writing many DVD's in as many different ways as I can think of. DVD(ISO) DVD(UDF) DVD(ISO/UDF) but NONE give me a successful DVD. Now I can open up a garage sale selling coasters!!! The writing phase works ok, 1X, 2X and 4X (although I dont tend to use the 4X). I have ticked the box in Neros Writing window to perform a verification of the disc when it completes. This is the problem. I noticed the problem over the past week since I backed up some similar files and tried to read them off the DVD-R(minus). The files are reported to be corrupt, and the occasional file which does manage to be read (for example a photo) appears very blocky and in no way a copy of the original!!! [bold]MY MAIN QUESTION IS THIS....[/bold] How do I successfully write a DVD backup of my file on my HDD using Nero 6 with my current PC configuration. It must be possible and Can only wonder if I am doing something fundamentally wrong. I imagined it was as simple as writing a CD backup. for the record I have successfully backed up some of my DVD-Video Discs on the same writer So am convinced the drive and system are working. Many many thanks to anyone who can help me.
