dvd missing or is cdrom problem again

I have a Toshiba Satellite a135-s4407 and am still missing my cd/dvd drive.
If I open device manager and check for hardware it says that there is a
TQSTcrmrp CD/DVDW TQ-L612d ATA Device and that my driver files are:
c:\windows\system32\drivers\cdrom.sys
and
c:\windows\system32\drivers\tdcmdpst.sys.

Both are checked on the Driver Files Detail box.
Tried uninstalling and restarting,restore,update drivers,filters(don't have
upper or lower in registry).

So the device is found but it says it is a cd-rom or dosen't show at all.
When I try to manually change the driver I can't select a .sys file it only
gives me a choice for .inf and dosen't show any files in the driver folder.
How do I fix this or get access to the right driver?
Thanks
