How to Fix USB Flash Drive Not Showing Up in Windows 10

When a USB flash drive does not appear in File Explorer, start with non-destructive checks. The issue may be a port problem, missing drive letter, damaged partition, RAW file system, or failing flash memory.

Background and causes

A USB drive can be visible in Device Manager but missing in File Explorer, or it may appear as RAW or unallocated in Disk Management. Each state needs a different repair path.

• Confirm the exact disk, partition, drive letter, file system, and capacity before changing anything.
• Recover or back up important files before formatting, deleting, converting, or recreating partitions.
• For boot-related changes, check BIOS/UEFI mode and boot order before editing disk layout.

Use Windows built-in tools

Try another port and computer, open Disk Management, assign a drive letter if the partition is healthy, update the USB driver in Device Manager, and avoid formatting when the drive shows RAW or unallocated.
