The driver has detected a device harddisk1 dr1 controller error

For stable operation of your system, you need to periodically review the event log, where information about crashes and errors appears. Quite often, controller error messages are issued there, even if at first some failures in Windows are not noticeable and everything works fine, in the future this can lead to negative consequences.

To begin with, let’s figure out what this error means in general and because of what it can occur. The controller is responsible for the operation of specific equipment, its operation may be disrupted due to mechanical damage to the cables and wires or due to a malfunction of a specific driver.

To find out the reason, you need to pay attention to the exact description of the failure in the log and conduct additional testing.

Controller system failures
One of the most common messages can be called the following – “the driver detected a device harddisk1 dr2 controller error.” As you can see from the content, there were problems with the computer’s hard drive. This is a rather serious threat to all the information that is on it and it is necessary to solve the problem as soon as possible.

The following factors may cause this behavior:

– errors in the drivers for the hard drive;

– Windows errors itself. Most often this is typical for Win7 and Vista, especially when Aero mode is enabled or if pirated copies of operating systems are installed;

– violations in the operation of the hard drive itself.

For a specific solution, additional information that can be found in the logs will help. It is necessary for remote assistance or for system recovery in a service center. For regular errors in the magazine, we recommend that you immediately consult in special forums or call a specialist at home. This will protect your computer from more serious problems and malfunctions.

Controller mechanical failures
Frequent power surges or physical shock loads on a computer can lead to disruption of various components, which can cause errors in the log. Experts recommend that the first step is to check the external condition of the laptop or system unit, as well as reconnect the cables.

The following situation may also arise, which is associated with a malfunction of the disk due to mechanical damage: the computer spontaneously reboots or the blue screen constantly pops up and reboots. When you try to boot, the following message is displayed: “A disc read error occurred”. After some time, after repeated attempts to turn on the system starts.

This is due to bad sectors, the presence of which leads to data loss and unstable operation of the system. Non-working sectors may appear after several years of operation of the computer or after voltage surges.

Such a controller error is determined using special programs for testing the hard disk. There are several programs that go into boot disks or flash drives.

They completely scan the equipment and display a detailed report on its condition, the report clearly shows the presence of bad sectors and indicates their number. If they are detected, it will most likely require replacing the hard drive and transferring all available information to a new medium.

Memory controller error and its solution
Sometimes there may be malfunctions in the RAM, this leads to a decrease in computer performance or a complete system hang. Most often, this error occurs due to violations in the operation of dynamic libraries or system files by various malicious programs or incorrect shutdown of the computer.

In this case, it is necessary to comprehensively approach the solution of the problem and begin to carry out actions in different directions. First you need to use the utility to clean the system from viruses and install a special program. Its principle of operation is not complicated, from the user you just need to start scanning and save the results that may be needed in the future.

If no defective elements are found after checking, then most likely you need to replace the electronic controller. The error is caused by a bad block in memory or an error in the memory controller. It is difficult to independently carry out this complex of work, it will require a lot of time.

After scanning and detecting a problem, we recommend that you take the computer to a service and provide the information you received there. The more detailed you describe the problem, the faster you will be repaired.

Component Conflict
Today it is popular to buy hand-assembled computers, where each component is selected separately. It is cheaper and you can get high system performance. But this can lead to controller errors if it is unprofessional to choose a motherboard, RAM, hard drive and other equipment.

The reason for such failures will not be visible during testing with different utilities, and system malfunctions begin after the first months of operation. The best solution would be to create a report through the Windows Support Center and consult with specialists.
