I have an HP Pavillion laptop (about 4 years old) with Windows 10. The DVD drive has suddenly stopped recognising any disks, whether CD or DVD, data or video. It /seems/ that the system recognises the drive OK, but not the actual disks. So far I have:-

1. Checked drivers for latest versions.
2. Uninstalled drivers, rebooted to re-install drivers.
3. Uninstalled drive, rebooted to reinstall drive.
4. Physically removed drive, checked the connections, and reinserted.
5. Checked and cleaned (carefully!) the read head transport to ensure that it moves OK. Even cleaned the laser head VERY carefully!!
6. Following advice elsewhere on the web, edited a Registry key to remove UpperFilters and LowerFilters (but there were none) also added new ATAPI entry.
None of this had any success.

Running the inbuilt HP hardware diagnostics, every time I try the DVD read test it asks me to insert a disk despite there being one already in the drive. This leads me to suspect a hardware fault – either the drive can not read the disk correctly or it can not even register that a disk is present.

Before I try to buy a replacement (I don’t really want to bother with a USB external drive), is there anything else that I could try?

What is the complete model number of the HP Pavillion laptop?

If possible, what is the complete make and model number of the CD/DVD drive?
