Except for the case of a physically damaged storage device, these are almost all the fixes that may help you in accessing the data storage when you encountered this error 0x8007045d message:

Try Different Ports

If you are using a portable data storage encountered with error 0x8007045d, just switching the device to another USB port would sometime work. One key point here is, most of the external hard disk uses a high power USB port to function properly.

For instance, in my ASUS laptop, when I try to connect my external hard drive to the USB 2.0, it doesn’t connect properly and sometimes, not shown in the device manager. Though it works perfectly fine in USB 3.0.

Consequently, this type of problem may occur to you. In short, try to use different ports. And if you are using a low quality extended USB cable, then try to connect the device directly to your pc.

Moreover, if you’re facing constant error problem with your external hard drive, try to connect directly to the back of your pc (motherboard USB port),

Restart Your System

Rebooting solves the majority of the problem. And this is called to be penicillin for the majority of system errors that are caused in an operating system.

And while rebooting your system, don’t use shortcuts to shutdown the system. Try to use the conventional system i.e. using the start button.

But before restarting make sure you save all your work. And follow the rule of thumb “one should restart their pc once a week if you regularly use it”.

Now, in the new pop-up window, click on the device manager.

Update Your Windows

Diagnose your Hard drive for Bad Sectors

For instance, all hard disks— not the flash drives— have a ‘sector’ on which the data is stored. When these sectors get damaged and inaccessible to the acquisition system then it is called a bad sector. Moreover, all the data that are stored in these sectors may have a higher chance to get lost permanently.

Often, when you have a storage-related error such as error 0x8007045d, there may be a higher chance that it is due to the bad sectors in your hard drive.

Conversely, there are a majority of tools that claim that they can retrieve the data from the bad sectors. But honestly, there is more chance that you won’t be able to retrieve all your data. Yet, these are some tools that you can try— Data Recovery, Check File System, Disk Benchmark, etc.

Repair Your System’s Registry

Sometimes the error main cause is a system database that is called the registry. Here all the crucial and basic data is stored that is accessed to provide the acquisition capacity for processing basic functions such as desktop setting, task managing, and other system files, etc. of the computer.

So, when some of the system registries get missing or corrupted, it may become the reason for error code 0x8007045d.

There are ample tools that can help you to correct or repair the system registry. These are Registry Repair, Glary Tracks Eraser, Glary Duplicate Cleaner, Disk SpeedUp, and so on. However, you can also try avg tuneup utility to repair and defragment your registry.

Disable Active Anti-virus Tools

When you are backing your system to the external drive, your active anti-virus tools may interfere with the operation by taking it as a treat. This majorly occurs because of the active firewall function of the anti-virus.

So, if you once get an error of 0x8007045d, you can disable the antivirus tool temporarily till your backup isn’t get completed.

One of the other reasons for this error is when you are copying files into your system, the system’s antivirus stops the process of copying because of a malicious threat administered by the anti-virus tool.

Thus, if you know (you must be sure) it is just a false positive indication, you can disable the anti-virus and then complete your file transfer.
