How to Fix ‘Inaccessible hard drives – Access is denied’ Error and Recover Data

Hard drive failure and recovery

The hard drive is one of the major storage components of a computer system. It stores various kinds of data like text, pictures, audios, videos, etc. Any problem arising in such hard drives could lead to inaccessibility of the data present in it. Such inaccessibility is often supported by various error messages. One of the most common error messages that make the hard drives inaccessible is  “Hard Drive is not accessible. Access is denied“.

Consider a scenario, where you are working on the D:\ drive on a computer, which consists of audio and video files. While playing some audio files, you might experience that audio is not playing through completely or instead it is playing some other file from a different location. Such a problem can be easily fixed by restarting the system or re-connecting the device if the file is on an external hard drive.

What is this error?

However, the problem can re-occur after some time. Also, you might experience some issues with the hard drive. A severe issue with your hard disk could deny you any further operations like creating or deleting of any folder on the hard drive. You can make use of the error checking tool to overcome this problem by navigating to Properties->Tools->Check Now. If you are lucky, you will not face the issue again while accessing the HDD and would be able to perform all operations on the hard drive.

Else, you would still be denied the hard drive access. In spite of the presence of drive icon in the Explorer, you might get the following error message.

“D:\ is not accessible. Access is denied.”

The error message indicates that there is some problem with the hard drive, which has made the hard drive inaccessible. In the worst case, it could also lead to data loss.

Windows XP

In the case of Windows XP, you might face the “Access is denied” issue if you have used an earlier version of Windows to create a volume based on NTFS file system and then installed Windows XP.

As the security ID of the person who created the folder was different on an earlier version of the Windows, in spite of the same username and password you do not have the permission to open the folder after you perform the following steps.

1. The actual location of the ‘My Documents’ folder has been changed before installing Windows XP professional.
2. Install Windows XP Professional, by formatting the primary partition.
