Error Code 45 is one of the very common Device Manager error codes in Windows 10/8/7, and this error message only appears on the screen if a device that was previously connected to the computer is no longer connected. In a word, when your hardware device reports code 45 error, Windows will not be able to read it. 

Therefore, to fix error code 45 on an external hard drive, flash drive or CD/DVD disc, it's more like that of finding solutions to fixing hard drive not showing up or recognized by your PC/Laptop.

Three, copy hard drive data and replace faulty hardware

The worst expectation for the error code 45 on a hardware device is about dealing with faulty hardware, which is almost beyond repair by the general Windows tools. If your system starts crashing, freezing or running slowly as soon as the device is connected, we almost assumed that the drive has developed some serious corruption issues. If you still feel uncertain, go to the nearest computer repair shop and let the technician examine it.

Once the corruption issue is confirmed, it's time to replace the faulty hardware with a new one. To copy as much data as possible off from the bad hard drive to the new one, use the EaseUS Disk Copy utility.

Prior Notice:

  • The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
  • All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the cource" or "Edit disk layout". 

check the diak layout
  • "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
  • "Copy as the source"does not change anything on destination disk and the layout is same as source disk.
  • "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

Step 4. Click "Proceed" to officially execute the task.
