Use Internal Optical Drive As External
Compartir
Most laptop optical drives use Slimline SATA (7+6 pin) connector rather than standard SATA. The good news is that these drives only require 5V power and can usually run directly from USB. The real challenge is choosing the correct adapter or enclosure.
Real Solutions
To convert 9.5mm or 12.7mm internal slimline drive into a portable external USB drive, you have two direct, affordable options.
Option 1: Slimline SATA to USB Adapter Cable (Best for Minimalists)
If you just want a quick, cable-only solution without any extra bulk, you need a dedicated Slimline SATA to USB adapter.
- What to buy: Look specifically for a cable labeled "Slimline SATA to USB." Do not buy a standard "SATA to USB" cable meant for 2.5-inch SSDs, as the power side of the data connector is too wide to fit a slimline optical drive.
- How it works: The single cable handles both the data transfer and draws the necessary 5V of power directly from your PC’s USB port. No wall outlet is needed.
Option 2: External Slimline Enclosure Caddy (Best for Portability & Protection)
If you want to toss the drive into a backpack or keep your desk looking clean, a bare drive with an exposed circuit board isn't ideal. A Slimline External Optical Drive Enclosure transforms your bare internal drive into a sleek, retail-grade external drive.
- Check Drive’s Thickness First: Before buying, you must measure your drive. They come in two standard thicknesses: 12.7mm (older laptops) and 9.5mm (modern thin laptops). A 12.7mm drive will not physically fit into a 9.5mm enclosure, and a 9.5mm drive will rattle around loosely inside a 12.7mm enclosure.
- The Setup: Pop off the front plastic bezel of your drive (if necessary), slide the drive into the enclosure until it firmly clicks into the internal 7+6 pin Slimline SATA slot, and snap the enclosure shut. It now connects via an included, clean USB cable.
Buyer's Checklist
Before you hit "Add to Cart" on an enclosure or adapter, double-check these two factors to avoid a return:
| Factor | What to Verify |
| Interface Type | Ensure your drive is actually SATA and not an ancient IDE/PATA drive (pins instead of a flat plastic tab). |
| Drive Thickness | Measure the height of the drive faceplate. It will be exactly 9.5mm or 12.7mm. |
| USB Generation | Opt for a USB 3.0 adapter or enclosure. USB 2.0 can support many DVD and Blu-ray drives, but USB 3.0 is generally recommended for faster file transfers, smoother playback of high-bitrate content, and reduced risk of buffering during disc burning. |
| Optical Drive Type | Not all slimline drives are Blu-ray drives. An enclosure does not add Blu-ray capability. If the original drive is DVD-only, it will remain DVD-only after conversion. |
FAQ
Can a laptop DVD drive run from USB power alone?
Yes. Most Slimline SATA optical drives operate entirely from 5V power supplied through USB.
How do I know if my drive is 9.5mm or 12.7mm?
Measure the height of the drive. Slimline optical drives are typically either 9.5mm or 12.7mm thick.
Will a standard SATA-to-USB adapter work?
No. Slimline optical drives require a Slimline SATA adapter because the power connector differs from standard SATA drives.
Can I use a Blu-ray drive in a DVD enclosure?
Only if the enclosure supports the same physical drive size and Slimline SATA interface.
