Errors 0x8007045d and 0x800703ee when copying files to a flash drive or memory card

Two similar cause errors when copying files to USB flash drive, SD memory card or external hard drive are 0x8007045d “The request failed due to an E error / S on device” and 0x800703ee “The volume of the open file has been changed externally, so it cannot work with this file ".

This instruction has several alternatives to correct the error and make the copy and in relation to the possible causes of the errors “The file could not be copied due to an unexpected error” with specified codes. Separate instructions about the error with the same code when installing: How to fix error 0x8007045d when installing Windows 10, 8.1 and Windows 7.

Bug fixes “The file could not be copied” with codes 0x8007045d and 0x800703ee

Possible causes of the error in question include third-party programs, especially antivirus tools; file system corruption on the drive you are copying from; USB controller problems, the USB flash drive or port and the memory card itself.

First, I recommend that you try the following 4 Simple methods to fix errors 0x8007045d and 0x800703ee when copying files:

1. Try disabling your antivirus.
2. If disabling antivirus hasn't helped, check if the copy has no errors in safe mode (see Safe Mode in Windows 10). If everything is fine in safe mode, it is very likely that some other third party software is interfering with normal file copying, most of the time it involves some cleaning utilities, system acceleration and optimization.
3. Check the drive where the file you are copying is located using chkdsk (See How to Check for Hard Drive Errors, method 1.) Please note that this can take a long time), especially in cases where a file previously downloaded from a torrent client is copied with an error. Also check the drive you are copying to.
4. If the error occurs when copying to a flash drive or external hard drive, try connecting it to a different set of USB ports, connectors located separately on the motherboard on the back of the PC or on the other side of the laptop.

If these simple methods don't help you, you can try other alternatives to fix the problem.

Other alternatives to fix the problem

If the previously described methods don't help, try the following additional options:

• Check if the official web portal of your motherboard manufacturer (if it is a PC) or your laptop has separate drivers for USB. If they are available, download and install them.
• If an error occurs while copying to the SD card, check if there are drivers for the card reader and install them.
• If an error occurs when copying to an SD card, try uninstalling the card reader in Device Manager, later select “Action” in the Administrator menu – “Update hardware configuration” to reinstall it.
• Warning: Performing this action at any time will cause the USB-connected keyboard and mouse to turn off, but they will turn back on after reboot. Therefore I recommend saving all important data first, and in the advanced settings of the power scheme enable the “Off” when the power button is pressed, to be able to restart. The method itself: if the error appears when copying to a flash drive or external hard drive, try erasing all USB controllers (“Root USB hub” items and / o "Generic USB hub") in Device Manager and then restart the computer.

These are all the solutions I can suggest. Just in case, you can try to use system restore points, but they are rarely useful in the current situation. It may also make sense to check the status of the drive being copied to another computer.; there is the opportunity that (unit) is due to a hardware failure.
