No access to the drive (access denied) how to fix this?

The Modern USB-drives are not immune from errors due to many reasons. Sometimes the system may display a message that no access to the drive (access denied), even though the user strongly believes that with the device all right. Why this happens and how to deal with this problem, read on.

The Message of the system “there is No access to the flash drive. Access is denied”: the causes of

The crashing of this nature may be caused by the same software problem, physical damage to the drive or (worse) errors in the operation of the microcontroller, viruses, etc.

In principle, to the flash drives today are usually referred to and removable memory cards. With them things are much simpler. Any adapter there is a special switch that puts the device into secure mode. In other words, to see the device and all that is on it, you can, but make some deliberate action – no. The simple solution – off the lock.

Worse is the case with viruses or file system corruption due to failures of policy due to a sudden power-off of the computer, improper removal of drive from the port, etc. In this case can occur converting a file system to RAW. It will have to return to the initial view using a low-level format. But, as a rule, the problem is not even that.

What to do in the first place?

When the flash drive says "access is Denied”, this should be understood as a prohibition, which must be removed. Usually you can try to produce only one action, which will be discussed below. But to ensure access to your device even with it is impossible. Therefore, the easiest solution is to format the drive. Of course, if it is not critical for user information.

Virus Autorun

Sometimes, warnings about the fact that there is no access to the drive (access denied) may be associated with exposure to viruses. One of those is the threat Autorun.inf, which is very often present in illegal software distributions.

In Fact, the virus itself is a substitute for the standard Windows service responsible for automatic detection of the connected media and select action. As is clear, to eliminate the consequences of its impact will have to do a full system scan. However, even if you use a regular antivirus, it is better not to apply the technology of S. M. A. R. T., which in most cases is enabled by default. After all, it is aimed at scanning of objects are vital to system operation in an accelerated mode. Therefore it is better to use in-depth analysis.

In addition, the most preferred solution to this situation would be the use of independent disk utilities with a common name Rescue Disk. They have their own download interface. It starts even before the execute Windows commands. And these are the scanners able to find even those viruses which are too deeply embedded in the system or settled in the main memory.

Flash Drive. Access is denied. What to do: the system registry

Now consider the most relevant method to eliminate this problem. If suddenly, for some reason the system says that access is denied to the flash drive, Windows 7 and similar systems can offer a radical solution of the problem. This will require intervention in the system registry. Its editor to be accessed through the regedit command in the console “Run” (Win+R).

Through the HKCU branch should reach the section MountPoints2 where clicking on the letter of the problematic device you can see the Shell subdirectory. Apparently, in the right window a file that meets the automatic startup will not be visible. So I just deleted the Shell key, and then try to open the drive. If you attended the original batch file, it can be hidden. Set the display of hidden objects in a “Conductor” and change the attributes. Then everything will go without problems.

Please note! This only applies to devices with AutoPlay, which is responsible for the file, positioned directly on them. In the General case, you can try to remove disk encryption or even enter the “device Manager" to remove the USB controller (no drivers, namely the device). Then, you must reinstall it when you reboot, using not database system, but only the driver downloaded from the manufacturer's website.

You Can do it even easier, when you restart the utility using Driver Booster. She will determine the type of device will download the most recent driver and integrates it into the system without outside involvement.

Tips for last

But in the simplest case, when the system issues a warning that for some reason cannot access the flash drive (refusedaccess), you can use even normal formatting. Of course, if Windows sees the drive, and it is not critical to the user. In all other cases you should carefully examine the nature of the failure. No need for the system registry better not to touch.
