I am not able to copy files from my internal Windows 10 hard drive

[Guest [email protected]]

Hello,

I am trying to copy files from my Windows 10 internal hard drive to a external hard drive.
About 50% of the transfer completes, and then I get this error message:

Error Code: 0x8007045D

Is there a way that I can fix this?

Thank you.

1. Try a Different Port and Cable

This sounds simple, but it fixes many I/O errors:

Unplug the external hard drive and connect it to a different USB port — preferably one on the back of the computer if it’s a desktop.

Try a different USB cable if possible. Faulty or loose cables often trigger I/O errors mid-transfer.

2. Check the Drives for Errors

Run Windows’ built-in disk check to find and fix bad sectors or file system issues.

For the external drive:

Open This PC.

Right-click the external drive → Properties → Tools tab.

Under Error checking, click Check → “Scan and repair drive”.

You can also use Command Prompt:

chkdsk E: /f /r

(Replace E: with your external drive letter)
This scans for and repairs bad sectors. It might take a while depending on drive size.

Do the same for your internal drive if the problem persists:

chkdsk C: /f /r

3. Copy Smaller Batches of Files

If a specific file is corrupt, the transfer will fail at that point.
Try copying a few files at a time to identify the bad one. If a certain file always triggers the error, that file is likely damaged. You can try:

Playing or opening it to see if it’s still readable.

Using recovery tools (like Recuva or CHKDSK with /r) to salvage it.

4. Disable Quick Removal Temporarily

Some external drives fail when caching isn’t flushed properly.

Open Device Manager.

Expand Disk drives, right-click your external drive → Properties.

Go to the Policies tab → select Better performance.

Try the transfer again, then safely eject the drive when done.

5. Try Copying in Safe Mode

Boot into Safe Mode (hold Shift while clicking Restart → Troubleshoot → Advanced Options → Startup Settings → Restart → choose option 4).
Then try copying again. This bypasses third-party drivers that might interfere with I/O operations.

6. If the Error Persists

You may be looking at:

Bad sectors on either drive (use SMART tools like CrystalDiskInfo to check health).

Failing external drive (especially if it’s older or makes clicking sounds).

File system corruption — sometimes reformatting the external drive fixes persistent I/O errors (back up what you can first).

If you tell me:

The brand/model of both drives

Whether the external one is HDD or SSD
I can suggest the most appropriate diagnostic tools (e.g., Seagate SeaTools, WD Dashboard, etc.).
