For some reason my Inspiron 5537 laptop intermittently chooses not to detect the DVD/CD rom drive. Discs can be read in the drive at random times, but usually I'm not able to use this drive. When checking the setup utility F2 . . . I noticed that the SATA ODD is not detected. Just yesterday it was detected (no changes were made to the computer during that interval). Is this a driver issue? I would appreciate any help in troubleshooting.
