I've had an oem Sony DW22A DVD writer (also apparently the same as the Sony 710A retail DVD writer) for about 6 months, and it has been working perfectly since installation.
The other day for the first time I was burning a CD-RW (I have burned and read many many cds and dvds already with just the odd error - usually based on cpu over usage). About 1/8 of the way through the burn, Nero had a problem with the burning process. This being not completely unusual, since I had a fair bit of CPU usage at the time, I wasn't too worried.
Later I noticed that although the drive was stilling showing up in windows explorer and My Computer (I'm using the newest version of Windows XP with all updates) it was not reading or even recognising that there was a CD in the drive. At first I thought the CD was wrecked - but I tried mutliple data cds that had already been burned - and each time, the drive seems to not recognize that any media has been inserted. No autoplay, and after a few minutes, still no listing of files on the cd coming up in windows explorer - even after refreshing the view.
Of course my first plan was to reboot - since i've had cd-writers in the past that had an error, and then needed a reboot to reset themselves. After a full shutdown, I have still had no luck reading CDs.
The plot thickens: i tried a data dvd - and the drive read this with no problem. I have also successfully burned a data dvd - and even still, it will not read or recognise when a cd of any kind is put in the drive.
I have tried manually removing the drive drivers, and reinstalling them. I've updated the firmware for the drive to the most recent BYX4 for the SONY 710A (which as I said earlier, is according to my research, the retail version of this drive that I got oem). I've turned off the computer and unplugged it for a few minutes. I've even taken off the side of the cpu and unhooked the data cord and power cord from the drive for a few minutes before powering it up - all these have had no success. (in terms of order - the firmware flash was the last thing i tried.)
I'm really at my wits end, but thought someone might know a way to proceed. I know there must be a way to "reset" the drive so to speak so that it goes back to factory settings. I find it odd that the drive can still read and write dvds but won't even recognise cds...
Does anyone have any ideas? Could an error like the one I described cause a fault with the drive itself? Could one of the many drivers involved somewhere have got corrupted?
Any help would be greatly apprecitated.
