Check the SATA data and power cables, confirm the BIOS SATA mode, then in Device Manager uninstall the AD 7240S entry and rescan for hardware.

Remove old/third-party optical drivers and burning software filters; let Windows install its generic CD/DVD driver, or roll back to the last working driver version.
