Frequently Asked Questions
Q: How do I know which caddy thickness (9mm, 9.5mm, or 12.7mm) to order for my laptop?
A: Check your laptop's optical drive bay size — this is usually listed in your laptop's manual or on the manufacturer's support page. You can also measure the existing optical drive's thickness. Most older laptops use 12.7mm bays, while slimmer modern models typically use 9.5mm or 9.0mm bays.
Q: Is this caddy compatible with both HDD and SSD drives?
A: Yes! The OULLX HDD caddy supports any standard 2.5" SATA drive — including traditional hard disk drives (HDDs) and solid-state drives (SSDs) — at 7mm, 9.5mm, and 12.5mm heights.
Q: Will my laptop recognise the second drive automatically after installing this caddy?
A: In most cases, yes. Once the caddy and drive are installed and the laptop is powered on, the operating system should detect the new drive automatically. You may need to format or initialise the drive if it is new before use.
Q: Does this caddy work with any laptop brand?
A: The OULLX caddy is designed as a general-purpose solution for notebooks that feature a SATA optical drive bay. It is compatible with most major brands including Dell, HP, Lenovo, Acer, Asus, and more — as long as the bay thickness and interface match.
