Issue with a SATA DVD burner not being recognized (no drive letter). PC is Windows 7 64 bit, ASUS p6x58d premium with the latest BIOS and SATA controller driver. C drive is a SSD and D drive is a SATAIII hard drive. One SATA DVD burner. I did sub in a differrent working DVD burner and have the same issue.

Started receiving a message at boot up: SATA 3 - Not ATAPI compatible F1 to continue. Flashed BIOS to latest version and message does not appear now at boot.. issue remains.

DVD drive is seen in the BIOS on the SATA list and in device manager under DVD/CD-ROM drives (withthe exclamation point icon).

the device status message in device manager is:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

Performing the driver update search through device manager states that the most current driver is already installed.

Using the diskmgmt.msc command I don't see the DVD drive or a drive letter conflict.

This issue started after a recent Windows 7 update/restart. I did also try setting the BIOS back to the default settings with change to the issue.

Is this as simple as a corrupt driver or ? any idea's would be appreciated!

Thanks,
Ken

Sorry for the post guys/gals.. I did find an answer that worked on the Microsoft forums. In case anyone else runs into this issue:

Step : Clear the upper and lower registry filters
Clear the registry filters for Device Manager error codes 10 , 19 , 31 , 32 , 39 or 41 using the following steps:
1.Use the Microsoft Fix it Solution from Your CD drive or DVD drive is missing or is not recognized by Windows or other programs (in English).
If you cannot use the Microsoft Fix it Solution, continue using these steps to clear the upper and lower registry filters manually.
2.Unplug all non-essential external plug and play devices, especially cameras.
3.Click Start , and then enter regedit into the Search field. Click regedit .
