I have a Toshiba SD-M1712 DVD-ROM and a LITE-ON SOHW-1653S DVD-Writer on the same computer running Windows 2000 SP4.
A week ago i disconnected the 1653S to connect a hard disk, then i remove the hard disk and connected the 1653S. Since then i am unable to read any dvd cd on either of them. CD-Rs are working fine, but when i put in a DVD-R cd the Toshiba's led wont go off, and on the Lite-On nothing happens and the computers asks to insert a cd.
This is the current configuration:
What went wrong? Why am i unable to read DVD cds?
