"Access Denied" is an error that occurs when Windows is unable to access the contents of a storage drive and this can be due to various reasons. Fortunately, this error is often easy to fix. In this post, I will explain everything about this error in detail so that you can diagnose the origin of the problem and at the same time I will teach you how to solve it step by step.
The error "Location is not accessible, Access is denied" may appear when a storage device, external or not, has restricted read or write permissions. This may be the result of user configuration or it may also be caused by an error in the information that constitutes the file system of the unit, for this reason, the first step to solve this problem should be to identify the source of the problem.
Digital information is made up of bits and these in turn are made up of binary numbers. It would be enough to omit or misspell a single digit for the integrity of the information to be corrupted. As you can imagine, this problem can not only affect the files stored inside a flash drive, but it can also damage the integrity of the device's file system and if this happens, all the information on the device would be inaccessible.
3. Access to the pen drive is restricted via Windows local group policy: Windows local group policy is a feature of the operating system that allows you to control certain parameters. There is a possibility that the write or read permissions of the flash drive have been restricted and this makes the device inaccessible. For this reason, it is important to grant read and write permissions to external devices through this utility.
4. The pen drive's file system is corrupted: As I mentioned earlier, file system data corruption can cause the device to be inaccessible. Earlier I talked about the possibility that this error is generated by a sudden disconnection and even by not having a sufficient power supply; however, it is important to remember that data corruption can also be generated by the intervention of a virus/malware. To determine if this is the case, it is advisable to carry out a scanning process with an antivirus or if you do not have one, you can use Windows defender to carry out this process.
5. The pen drive is conflicting with the certain application: Sometimes, applications installed on Windows may interfere with the operation of Windows, this may be because one or more applications have permissions to manage certain functions of the operating system and this, in turn, can trigger all kinds of problems. For example, there are applications that intend to customize, sort, filter, optimize space, encrypt or even add additional search functions for USB drives and if these applications fail due to an outdated or incompatible version, this could be the reason why the error "Access denied" appears.
Now you must find and open the file "Removable Disks: Deny read access" and tick the option "Disabled" to remove the restriction of reading data on external storage devices, although this may solve the problem, it is advisable to repeat this step with the files "Removable Disks: Deny write access" and "Removable Disks: Deny execute Access"
The file system of a storage device is necessary for the operating system to be able to interpret the structure of a storage device and thus have access to the information of the device. Fortunately, Windows has a diagnostic and troubleshooting tool for these kinds of problems. This is "CHKDSK", to access this tool you must use Command Prompt in administrator mode. Through this command, Windows will thoroughly analyze the device to reconstruct the missing information and thus restore the operation of the device. Below I will show you how to use it.
The solution to this problem would be to use a computer with a compatible operating system to access the information from the USB, however, this may be an impractical solution for many users, and for this reason, the most effective and practical option is to use a data recovery software. In this way, you will be able to access the information of the device regardless of whether the error was caused due to the incompatibility of the device's file system or data corruption. Personally, I recommend Recoverit. This software is extremely easy to use. From the moment you install the software, it is able to automatically recognize the compatibility parameters of your operating system, therefore, when recovering information from a device, Recoverit will automatically perform the processes that are necessary for you to access the information with just a couple of clicks.
As you may have noticed, in the vast majority of situations, the "Access Denied" error is very easy to solve, but if your case is more complex, you can simply choose to recover the information from the device with the help of Recoverit and if you consider it prudent. You can reformat the device to restore the information on it but this time you will be guaranteed compatibility with Windows operating systems.
