The machine is a 6-month old Acer Veriton M221. My DVD drive has stopped being recognised by the OS. I'd rather avoid sending the machine to Acer so need to identify whether the drive has failed or whether it's just a driver issue.
I've done all the obvious uninstalling and reinstalling in Device Manager, but it makes no difference. Windows 7 won't see the drive, despite it being there and happily accepting discs, whirring, flashing its lights etc.
In Device Manager three .sys driver files are shown, but I've no idea which one if any is the cause of the problem! These are:
cdrom.sys
eLock2BurnerLockDriver.sys
UBHelper.sys
The message shown is "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
Does anyone have any ideas on where to go to get copies of these drivers?
Cheers.
