This is a Thinkpad T430, running W10 32 bit. The DVD drive is listed, but discs cannot be read. Tried various home made and commercial disks, which used to work. The head is parked where it should be, and moves freely. Laser has been gently cleaned. The drive LED flashes, and drive 'clicks' as expected.
Tried searching for a new driver, uninstalling and reinstalling, and the Windows Troubleshooter, rebooting after each operation. Still nothing.
This *may* have happened after the last Windows upgrade, but not sure.
Any bright ideas?
