TROUBLESHOOTING GUIDE

Why is my SSD not detected?

An SSD can be missing for very different reasons: a loose connection, unsupported slot type, BIOS setting, a new uninitialized drive, damaged partition data or actual SSD failure. First determine whether the drive is missing from BIOS or only missing inside Windows.

What the symptom can mean

Possibility 1A new blank SSD may simply need partitioning before File Explorer shows it.

Possibility 2M.2 SATA and NVMe compatibility mismatches are common.

Possibility 3A loose SATA data/power cable can make a 2.5-inch SSD disappear.

Possibility 4BIOS storage-mode changes can affect Windows booting and visibility.

Possibility 5An SSD can fail suddenly with little or no mechanical warning.

When to stop DIY troubleshooting

If the SSD contains valuable files and is intermittently disappearing, do not keep writing data to it or repeatedly initialize it. Recovery strategy depends on whether the controller still responds.

When professional diagnosis makes sense

If the simple checks do not identify the cause, diagnosis can prevent unnecessary parts replacement. Laptop Clinic serves NDG and Greater Montréal. Describe the symptom and what happened before it started; you do not need to know the technical name of the fault.

Useful details before a diagnosis

Note the exact computer model, when the problem started, and any recent change such as an update, drop, liquid spill, new part or new charger. If the problem is intermittent, a short video or photo of the error can help. For storage-related problems, always mention whether the files are important before any reinstall, reset, initialization or formatting attempt.
