When an external drive stops appearing, Windows may stay silent, play the USB connection sound without showing files, or ask you to format the disk. That last message is easy to misunderstand. Formatting is not a repair step when the data matters; it writes changes to a device that may already be unstable.

Start with low-risk checks. Try another USB port, another known-good cable, and a different computer if available. If the drive uses a power adapter, make sure it is the correct adapter for that enclosure. Avoid shaking the drive or repeatedly unplugging it while files are being read.

Listen before you keep testing

A healthy portable hard drive usually spins smoothly. Clicking, beeping, repeated spin-up, or a drive that connects and disconnects every few seconds can point to a physical fault. In that situation, stop testing and keep the drive powered off. More attempts may reduce recovery options.

External SSDs can fail more quietly. They may appear with the wrong capacity, vanish under load, or freeze File Explorer. If files are still visible, copy the most important folders first instead of organising everything.

What to tell a repair shop

Useful details include the drive brand, whether it is HDD or SSD, what changed before the fault, and whether it was dropped or exposed to liquid. A photo of the label and the exact Windows message helps.
