Hello. I recently bought this drive and worked just fine with dvd r. When i tried to format an older dvd-rw i used to backup my data on with my old dvr-108, in nero 7 it gave me this message: “This disc is not rewritable and therefore cannot be erased”. I can tell you i checked and the disk IS rewritable, and brand new. After i wrote a file on it just to test it i could’n write anymore. it’s like the dvd-writer confuses dvd rw with dvd r. anyone can help? Thank you!
Solved it by uninstalling and reinstalling the device. Turned out to be a software problem! Thanks!
