4 Effective Methods to Fix Undetected Hard Drive

Method 1: Fix the Unrecognized Hard Drive By Changing The Assigned Letter

  2. In the new window, click "Change." Here you can assign a new drive letter to your USB and click "OK." This should fix the problem.

A used device can suddenly produce unallocated space. Unallocated space cannot be used to store data. To use the space, you need to create a partition on it or divide it into multiple partitions. Accidental partition deletion, virus attacks, or other reasons can cause this type of disk partition loss. You simply need to recover the data from the unallocated space and create a new disk volume to reuse it.
