SelfSufficient

Thank you - that resolved the problem.

Either the drive isn't initialising the disc properly or some other program (Alcohol / DAEMON Tools) is forcing it to look like a DVDROM. ImgBurn won't know how to handle the disc properly unless the drive correctly reports what it is. Thanks, that makes sense - post the initial burn, other devices are reporting that it is a DVDROM - plus I do have Alcohol and DAEMON tools installed. I did close down these applications though, so am surprised if they are still manipulating the device. Will retry, perhaps removing Alcohol & DAEMON and see what happens - do you know if the discs are now caput?

Hi, I am able to write once to some Verbatim DVD+RW disks on a PIONEER DVD-RW DVR-110D 1.41. When I try to write over it a second time I get the following: Close track failed! /Device [0:0:0] PIONEER DVD-RW DVR-110D 1.41 (d:)(ata) /Reason: Invalid field in CDB ImgBurn does allow me to format the disk (where as Nero does not) - but both Nero and ImgBurn think the disk is not empty and will not allow files to be written. I would be greateful if someone could diagnose the issue.
