My internal dvdrw did same. However it's dead now.
More about what to try with yours. Boot SAFE MODE (see google about things you don't know) and head to the DEVICE MANAGER to remove, delete, or uninstall all CD/DVD drives.
Reboot and retest.
I have a problem with my DVD burner. When I start up my computer, the BIOS finds it no problem. It shows on Windows Explorer and I can read CDs and DVDs. The problem is when I burn, I get this message "Device not available". I put a different burner, I get the same message. Any help will be appreciated.
The DVD burner shows as LITE-ON DVDRW LDW-851S.
Intel Pentium 4
Windows XP SP3
300 GB HDD
