Please insert a blank disk in drive E

My OS is Windows XP and I'm using Windows Media 11.

I am unable to burn CD's both data and audio using my 'writing' drive E. I
keep getting the message telling me to insert a blank disk in the drive. The
drive fails to recognise that a disk has been inserted.

I've tested the drive by inserting a data disk and this is recognised and
runs automatically. However nothing happens when I insert a DVD or audio CD.

Previously I've had no problem. I haven't tried to burn anything for over a
year now so maybe I've installed or uninstalled something which has now
caused the problem.

The drive description is HL - DT - ST - CD-RW GCE-8483B if this means
anything to anyone.

I've tried reducing the hardware connected to my USB ports and this seems to
permit data disks to be recognised in the E drive but even when I disconnect
all of the the drive still won't play CD's or DVD's.

As a humanitarian act, is there anyone out there who can help prevent me
from propelling the PC through my front window? Save a PC now!
