I tried contacting Sony with the following message but they were not helpful at all. quote:I am trying to burn some data onto a DVD+R disk (manufactured by sony) but my drive does not detect the disk. Whenever I insert the disk, it changes the name of my drive from "DVD-R Drive" to "CD-ROM Drive". Looking at "Details" it says the drive has 0 bytes of free space and the total size is 0 bytes. When I go into the volumes properties, the information is given as follows: * Disk: CD-ROM 0 * Type: DVD * Status: Online * Partition Style: Master Boot Record (MBR) * Capacity: 0 MB * Unallocated Space: 0 MB * Reserved Space: 0 MB This is a PCG-GRV680 Laptop with a Sony DVD+/-RW DW-U50A optical drive. They told me to reset the BIOS and reinstall the driver but that did not help.
