Question 1

Drive not detected?

Accepted Answer

Confirm the Optiarc AD-5170S appears in BIOS and check its SATA cable/power. In Windows, open Device Manager > DVD/CD-ROM drives and scan for hardware changes. If still missing, install the motherboard chipset/SATA drivers—not a separate Optiarc driver.

Question 2

Install or firmware update fails?

Accepted Answer

Run the updater as administrator, close burning/ripping apps, and use the exact AD-5170S firmware file. Do not flash if the drive is not stable or connected through an unreliable adapter.

Question 3

Version conflicts/error codes?

Accepted Answer

Uninstall duplicate or old DVD/CD-ROM entries in Device Manager and reboot so Windows reinstalls the generic `cdrom.sys` driver. Avoid third-party driver updaters; only remove upper/lower filter entries after backing up the registry.
