I just got this Sony Vaio PCG-GRT716S, but I am experiencing a problem with the DVD / CD- RW. When I insert a disc I get a message to insert disc to drive E, even if I have already inserted a blanc DVD. When I try to drag and drop, I get the message insert disc code 011 - 02 - 1028.
Also if I try to remove files from the disc inside the E drive I get the same message.

Sometimes the disc is detected, and I can write to the disc, as soon as the disc finishes to record to the disc, the disc ejects from the drive. when I insert it back into the drive, it can't find the files that was copied. Later it maybe finds, but can never be sure. Also the properties of the disc always shows the disc as full, even though it is empty.
Please if anybody know how to solve this problem let me know.
