DVD/CD disappeared

  dugit 18:05 06 Mar 2010

Have Medion Akoya p4 4101D.
Was on pc doing things and went to use the dvd/cd and found it was no longer showing on the computer.
I went through computer-properties-device manager double clicked on cdrom it came up with :
"Windows cannot load the device driver for this hardware. The driver may be corrupted or missing"
What do I need to do?

if a driver is already installed remove it and reboot let windows detect it

if that doenst work you may have to open up the box check the power and eide /or sata cables are connected properly

worst case scenario is that the drive has failed fortunatly they are not to expensive these days and fairly easy to swap out

hope this is of some help

should add if you do have to open case make sure power lead is removed first

What op system?

98 XP Vista
Virtually all CDs /DVDs players and writers will use the same windows drivers. they are in the windows\system32\drivers\ or windows\system32\DRIVERS \ folder and are:-





and in the windows\system32 folder


try device manager update driver and install these files. to get your CD/DVD working again.

This really does seem to be a big problem with Win 7
