DVD drive problem: HL-DT-ST DVDRAM GSA-T20N ATA Device
Hi! Can anybody help me? I think I erased the HL-DT-ST DVD Device from my notebook by accident and now my dvd disc drive does not work anymore please help
you must start regedit ( start -> run [See screenshots at the bottom] Type here: regedit )
search the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class/ search for "4D36E965-E325-11CE-BFC1-08002BE10318" if you doesn't find anything, search only for a part of the string.
now search the propertys UpperFilter an LowersFilter and kill the value. If only one prop. is there, you must kill only the one value
Hey DeadMatt, you are a genious. I arrived here seeking desperatly for a solution or a driver, because suddenly my drive stopped working. The laptop is a fujitsu N6460 about two weeks old, vista home premium. Am pretty sure windowsupdate ruined the driver settings, but now is working again. As an additional problem, I could not read the drivers cd, because well, no cd! Your recommendation on tweaking the registry worked perfectly.
DeadMatts solution worked a treat. Got my DVD drive back and working. I used CD's to install various software options on day of new notebook delivery then DVD drive dissapeared. I reckon it must have occured during a microsoft auto update...anyway, thanks to DeadMatt, all fixed.
My dvd-rom wont work at all. I got this registry tip before. But the neither UpperFilter nor LowerFilter is there at all. Nothing will work with the cd\dvd drive at all. I've updated the drivers.
i followed everthing but appears the same. After i changed the value to 0 it does not make any changes Do i have to restart the computer or wait for a period of time because i need to use dvd drive to install some programs if someone has a solution for me please reply mi laptop is a Pavilion dv5-1235dx Entertainment it came with windows vista home premium 64 bit i just got it. thanks
HiThank you very much!!! At first i didn't think your trick was going to work at all, but in totally worked! You're a tiger (tiger = master), again thank you!!!Bye
i just bought the acer aspire 5535 and it cant read certain games or dvds. i've tried reinstalling the driver (HL-DT-ST DVDRAM GT10N SCSI CdRom Device) but its not had any effect. anyone got any ideas how to get it to read them? its supposed to be able to play all dvds and be great for gaming but so far i'm not seeing that.
