Anyone good at reading error reports?

Not sure if this belongs here or in the Heneral Hardware forum although my DVD-RAM drives are brand new and have been working perfectly until a few minutes ago.
I’m in the habit of burning regular backups to DVD-RW media and thus far everything has run smoothly. Now, all of a sudden, Nero Express fails a short way into burning. This happened with Radius Odoruku 2X DVD-RW and the current Ridata 6X (showing as Ritekw06).
All I’ve done today is realign my drives letter-wise…that shouldn’t have any effect.

Here’s the log:

Forget it guys…it must have been the relettering of the drives that screwed it up. I uninstalled/reinstalled the drives and now everything is normal again…sorry!!
