Avoid Copying or Transferring Large Files on Your Computer

You'll require administrative permissions to address this issue.

1. Connect Your Device to Another PC or Use a Different USB Port

Eliminating hardware issues is the initial step in addressing the error. The easiest approach to do this is to connect your external hard drive to another device, provided you have one available. Once connected, attempt to transfer the same type and amount of data to or from the disk to see if the error persists. If the issue occurs on the other device as well, the problem lies with your external hard drive, not your operating system. In this case, proceed to implement the fixes listed below.

The following method involves connecting your device to a different USB port.

USB 3.0 ports provide faster data transfer speeds and more power than USB 2.0 ports. If you experience difficulty copying files to or from a hard drive connected to a USB 2.0 port on your computer, disconnect it and plug it into a USB 3.0 port instead.

This helps eliminate the possibility that the error was due to slow transfer rates or insufficient power from the USB connection. If the device is already connected to a USB 3.0 port, try plugging it into a different USB port to see if that changes anything. After switching ports, initiate the file transfer process once more. This method can also be used to resolve the issue of a USB not appearing in Windows.

2. Update or Reinstall the Driver to Resolve Error 0x800701b1 on Windows

It's crucial to keep your drivers up-to-date to avoid compatibility issues that might cause your PC to function improperly. If error code 0x800701b1 is due to an outdated or corrupted driver, attempting to download and update USB drivers should resolve the issue.

You can visit the manufacturer's website to download the driver software assistant. First, ensure you identify the correct driver model and your Windows version. Then, download the appropriate PC driver for installation.

3. Resolve Error 0x800701b1 by Rescanning Disks in Disk Management

If connected drives are not accessible, Windows users can rescan the drives through Disk Management. Rescanning might resolve the 0x800701B1 error, although it's less common. To initiate the rescan, follow these steps: 1. Press the Windows key + X on your keyboard to open the Quick Access menu. 2. Select "Disk Management" from the list of options. 3. In the Disk Management window, right-click on the drive that is causing the error and choose "Rescan Drive" or "Rescan Disks." 4. Wait for the rescan process to complete. This may take a few moments. 5. Once finished, check if the error persists. If the issue continues after rescanning, you might need to explore other troubleshooting methods.

Step 1. Press the Windows key + R to open the Run command box, and type 'diskmgmt.msc' into the text box, then press OK to open Disk Management.

Step 2. Click on the Action tab and select Rescan Disks from the context menu.

The rescan should only take a moment. After it's done, transfer the data again to see if the issue has been resolved.

4. Perform a Disk Scan on the Affected Drives on Your Computer

Users can locate and fix file system errors on their drives using Windows' built-in disk scanning software. Here's how to perform a disk scan on both the source and destination devices: 1. **Access Disk Check Utility:** - Press the `Windows key + X` to open the Quick Link menu, then choose `Command Prompt (Admin)` or `PowerShell (Admin)` if you prefer a more modern interface. 2. **Scan the Source Device:** - In the command prompt, type the following command, replacing "X" with the letter of your source drive: ``` chkdsk X: /f /r ``` - The `/f` flag tells the tool to fix any errors it finds, while `/r` scans for lost information and attempts to recover it. 3. **Schedule the Scan:** - If the drive is in use, you'll be prompted to schedule the check for the next restart. Type `Y` and press Enter to confirm. 4. **Restart the Computer:** - Restart your computer and wait for the disk check to complete during the boot process. 5. **Scan the Destination Device:** - After the system has restarted, open the Command Prompt (Admin) again. - Repeat step 2, but replace "X" with the letter of your destination drive. 6. **Review the Results:** - Once both scans are finished, review the output in the command prompt for any reported issues. If errors were found and fixed, they should no longer pose a problem. Remember that performing a disk check can take some time, especially if the drives are large or contain many files. It's recommended to do this process when you won't need immediate access to the computer.

Step 1. Open File Explorer from the Windows taskbar.

Step 2. Click on "This PC," find the external drive connected to your PC, right-click on it, and select the "Properties" option from the context menu.

Step 3. Click the Tools tab in the Properties window and click the Check button under Error Checking.

This is an image depicting an "Error Checking Tool" on a Windows operating system, used for scanning and detecting issues with an external drive. The image shows the window where a user can initiate a check for errors on the external storage device.

Windows will notify you if a disk scan is necessary. Perform the scan on the external drive regardless of its recommendation, and then repeat the process for the destination drive.

5. Attempt to Resolve Corruption Issues on Your Hard Drive

Your operating system might encounter errors due to corruption on your hard disk. When trying to move corrupted data files from your external drive, you might encounter the error code 0x800701B1. To rule out this issue, it's advisable to perform a data corruption scan on your hard disk.

Running a disk check scan will definitely be helpful in this case, but for a more accurate detection of corrupt files, you'll want to use third-party data corruption apps. These tools can confirm if the damage is beyond repair after a basic disk check. You can fix damaged files and make sure security permissions aren't hindering file movement, unless the drive itself is faulty. To check if security permissions are affecting file relocation and to assess the drive's integrity, you should utilize specialized software for repairing corrupted files.
