Hi, I've had this problem for a while and not been able to solve it after trying various things, so I'm not sure whether the drive itself is to blame or not.
My drive is DW-U50A +/-RW, which is updated with the latest firmware for it - 1.5g. I'm running Windows XP SP1 with fully functional ASPI drivers. Previously, all I've used are CD-R's and DVD-R's, both of which have worked fine.
But I've recently been trying to use DVD+RW discs with no success whatsoever. I have tried Imation and TDK (4.7GB, 1-4x) discs. Currently I'm still trying to get the TDK discs to work. When I insert a new blank disc, in My Computer the drive changes from 'DVD-RW E:' to CD drive E:, although properties show 4.37GB free on the disc.
When I use Nero, quick erase does not work correctly, and when I try to burn data, before the burn process is about to begin, there's an error and Nero states it is an 'illegal disc', identifying it as a DD-CDROM?!
I have also tried using DeepBurn software, which comes up with the error - "this media is not writeable".
WriteDVD! is also unable to format the disc for UDF use.
Nero InfoTool shows the disc info as being a 4.7GB DVD+RW but having 0.00GB capacity.
I have also tried turning off XP's IMAPI service, which makes no difference, and also made sure that 'autorun' is disabled.
I'm at a loss with what to do, I'm sure it can't be the media, I have tried 10 Imation Discs and 5 TDK discs, none of them will let me burn/erase/format in any way.
I'd be very grateful for any help!!! This is annoying to say the least.
