How to Recover Data Lost After Changing the Drive Letter

Summary: Data lost after changing the drive letter is the most common issue user faces. Here in this blog we tried to give all the best solution that user can try to recover his data after changing the letter.

How to Recover Data Lost After Changing the Drive Letter

Drive letter plays an integral part in the PC environment. It is a single alphabetic character (from A to Z), which is assigned by the Windows OS to the connected drive volumes or partitions.

A drive partition or volume—whether internal or external—is not accessible unless it is assigned a valid drive letter. But what happens when we change the drive letter or assign a different drive letter to a drive?

Change Drive Letter

For instance, if you have installed some programs or stored files in different volume other than C: changing letter will make them inaccessible. In simple words, it breaks the things in your system.

All the installed programs will stop working, as they will not be able to find the required files at the address saved. Any project you are working on will be lost. That’s why windows display a stern warning message when you try to change the drive letter (see screenshot).

Drive Letter Not Correct

However, reverting to previous drive letter can solve these problems.

This implies that data is not usually lost or deleted when you change the drive letter. However, it’s not recommended that you change the drive letter, unless necessary. Changing drive letter is closely associated with data loss as people often accidentally end up formatting the drive while assigning a new drive letter.

Once drive is formatted, data is lost completely. In such a case, a data recovery software can save you from such situations—and that’s the only way.

Also, if the drive letter is not assigned to (or removed from) the drive volume or partition—may happen accidentally or if the system is infected with malware or virus—the drive becomes permanently inaccessible, and the user loses the access to their data forever (see screenshot).
