Can U Advise Me Please

To do periodic data backups, I reuse a DVD-RW. In Roxio EMC 10, I use Data & Backup - Data Disc option. I load folders into write list from their sources and burn as a 1 session (in case I ever have to recover the data on a different PC). I always add to the write list the most recent prior backup data set that is already on the DVD. As expected, selecting data that resides on the DVD I will write to, causes Roxio to copy that data to my Hard Drive first. When I initiate the Burn, msg asks if I am OK with erasing the disk as necessarily occurs with a RW disk overwrite. I click YES and Roxio erases disk then proceeds with the burn.

This has worked before w/o problem, but now I consistently get msg that it cannot write the files it got off of the disk from the prior backup session. This despite > adequate capacity on the DVD and DVD not having been used nearly to it's max. number of burns.

Any ideas how to troubleshoot, fix?

The chances are the disc itself is the problem

 

There is only a limited number of times you can reuse a rewritable disc before it eventually fails

If the files are important, try downloading ISOBuster to see if it can read anything off the disc.
