I have a OptiplexGX620
Bios Version A11 (11/30/06)
Phoenix Rom Bios Plus

For about 8 weeks I have been trying to get this DVD drive to work in my PC! This DVD drive is a Lite-On IHAS124-04 Internal DVD Writer. The problem here is that its not recognized by the PC. The little light turns on when I turn the PC on, and the DVD tray works aswell. But when I put something in there it doesnt show, when I look for it on my computer it doesnt show. When I re-start my computer I get this error
Drive 5 not found: Parallel ATA PATA-1 (PRI IDE SLAVE)

Things that I tried: buying a different sata cable. Switching the power supply. Tried using a different slot. Tried looking for it in bios ATAPI didnt see it! I have two drives so I let one drive use the power from the powersupply. and scanned for new devices, looked in computer management/storage to see if windows sees the drive there it didnt

Brief overview and targeted checklist for 's OptiPlex GX620 (BIOS A11, 11/30/2006) and Lite‑On iHAS124: the drive powers and the tray opens but the BIOS/Windows never enumerates it, and the POST message about "Parallel ATA PATA-1 (PRI IDE SLAVE)" points at the BIOS looking for an IDE device rather than seeing a SATA optical. That narrows the problem to: wrong/loose connection, a disabled or failing SATA port/controller, a Windows driver/filter issue, or a faulty drive.

Step-by-step checks (ordered to isolate quickly)

  • Physically verify connectors. The iHAS124 is SATA — make sure the thin 7‑pin SATA cable is plugged into a motherboard SATA header (not a wide PATA ribbon or an adapter). Reseat both ends firmly.

  • Power correctly. Use a direct SATA power lead from the PSU (avoid cheap Molex->SATA adapters or splitters). Adapters can supply power but sometimes cause detection problems.

  • Swap ports/cables and test with a known device. Move the drive to a different motherboard SATA port and try a different known‑good SATA cable. Conversely, attach a known‑good SATA HDD/SSD to the same cable/port to confirm the port/cable are functional.

  • Confirm BIOS settings. Enter Setup and ensure the onboard SATA controller and the specific SATA port are enabled. Reset BIOS to defaults (or clear CMOS) if settings look off. Note: switching SATA mode (IDE/AHCI) can affect Windows boot — record current settings before changing.

  • OS-level isolation. Check Device Manager (not just Disk Management) for unknown devices. If Windows shows nothing, follow Microsoft’s CD/DVD troubleshooter or the UpperFilters/LowerFilters registry fix (the fix referenced). If you prefer ’s approach, boot a live Linux USB and check hardware messages.

Linux quick checks (from a live session)

sudo dmesg | tail -n 40
lsblk -o NAME,MODEL,SIZE

Interpretation and next steps
The POST about PATA is likely unrelated to a SATA optical — remove that missing PATA entry from the boot list to stop the POST message. If the drive never appears on another PC or via a USB‑SATA adapter, the drive is likely dead and should be replaced/RMA’d. If it works elsewhere, the OptiPlex motherboard/BIOS is at fault — consider a BIOS update only as a last step following Dell’s instructions.

Have you tried booting a live Linux CD/DVD/USB drive to see if it recognizes the device? Are you sure it is installed properly? It is a Sata device, not an IDE one?
