Toshiba SD-M1712 and Lite-On SOHW-1653S cant read any DVD cd

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?

Is Auto Insert Notification also off?


#3

If by “Auto Insert Notification” you mean the “Disable Autoplay” group policy entry then its set to “Not Configured”.


#4

It has nothing to do with Autoplay.

You could easily check it with DVDDecrypter, ImgBurn or CloneCD.

ImgBurn shows Auto Insert Notification is disabled.
Booting from a dvd also failed. maybe its not windows problem but a bios?


#6

I booted knoppix and still i wasnt able to read any dvd disc.
What else is there to check?


#7

What types of DVD have you tried so far??


#8

TDK and Samsung DVD-Rs.
These are cds i burned a while back.


#9

I tried disconnecting one of them and leaving just the other. same result. anything else i can check to know if its a hardware or a software problem?


#10

Check the ide connector pins at mainboard and drive for damage.


#11

okay, i replaced the ide cable. didnt help.
i replaced the 1653S drive with a new one of the same model, it worked for a while and then it stopped.
i plugged the toshiba to another computer and it can only read dvd+r.
if my old 1653S was broken, how come the new one is not working?
are there any BIOS settings i need to reconfigure?


#12

I replaced the SOHW-1653S twice until i got a working one.
The SD-M1712 is still broken. Probably hardware problem.
Thanks again everyone!
