One of the most commonly used methods to classify hard drives is to sort by the placement of the disk. Thus, hard drives are divided into external hard drive and internal hard drive. Now, here comes the problem: when you add a new drive to your current computer, it’s possible that the hard drive doesn’t appear (no matter it is connected as an internal drive or external/USB drive).

What do you plan to do when this actually happens to you? Have not thought about this question? It is okay, we’ve already figured it out for you. And we’ll show you specifically how to recover data from not detected hard drive and how to fix the problem (making hard drive appear and usable again).

A Good Way to Recover Data When Hard Drive Doesn’t Appear

Recently, we heard a lot of people said that they have found their hard drive is not showing up in Windows Explorer. As a result, they lose access to all their data saved in that drive. Therefore, they want to fix the hard drive not showing up problem and get back the data they need.

Considering that data may be lost during the problem solving process, we advise you to recover data in advance and then try every possible way to work thing sout.

Here’s how to recover data from non-detecting hard disk:

Firstly, please get MiniTool Power Data Recovery, which is a popular hard drive recovery program. Then, install it to another drive on your computer and open Windows Disk Management (WDM) to see the state of the non-detecting drive.

Secondly, start the software to see the following main interface and then decide which module to choose.

For instance, if your drive shows up in Disk Management and the partition doesn’t lose, you should choose “Damaged Partition Recovery”; but if the drive appears in DM and the partition is missing, you may resort to “Lost Partition Recovery”.

Thirdly, select the hard drive which doesn’t appear on your computer from the following interface. Then, click on “Full Scan” button to start searching for files in it.

Fourthly, browse all the found folders and files at the end of the scan. Then, pick out which ones you need and add a check mark in front of them. After that, click on the “Save” button to set a storage path for the files you plan to recover and press “OK” to confirm your selection. At last, wait for a while until the recovery has been completed (a prompt window will show up when the recovery work is finished).

It is recommended that you store the files& folders to another drive. Otherwise, the original data may be overwritten.

This is the end of data recovery from not showing up hard disk. This works great when an internal hard drive doesn’t show up or an external hard drive doesn’t show up in My Computer.

But, you need to notice this: if it is the bootable internal hard drive (not the second hard drive) that has been broken, you’re not able to enter the system anymore; so above method is not available. In this case, data recovery from corrupted internal hard drive becomes necessary.

Reasons & Solutions for Hard Drive Not Showing up Problem
