CDRW will not read recordable media

[Brendan]

Hello,

My CD-RW drive plays all media fine, but does not
recognize or allow me to record to recordable cds. When
I insert a blank disk, the activity light goes nuts and I
can hear that the drive is working, but nothing happens
(the autorun menu doesn't pop up, and XP won't let me
burn to the cd--it says that there is no media present in
the drive).

I am running XP Pro. I have a generic 52x24x52 CD-RW
drive. Device manager says it's working fine. I've
uninstalled and reinstalled the drivers.

What should I do?

Thanks,

Brendan
