Windows 7: Acer TM4740 DVD drive problem

10 Nov 2011   #1

Windows 7 Ultimate 32bit SP1
Acer TM4740 DVD drive problem

Sometime ago it was working perfectly now after upgrading to sp1 it is not working. After burning dvds and cds it show error and shows them blank but other computers show them perfect. So I replaced cdrom.sys and cdrom.inf and it worked but after restarting it stopped working again.

Now I installed fresh copy of Win 7. It worked for few days but then problem occurred again. I uninstalled driver now it detects the drive but shows in other devices and show message that 'Windows was unable to install your HL-DT-ST DVDRAM GT31N'.
