Windows 7 backup failure

Question

I get error messages (see below) when attempting backup to external HD. How to cure? I'm guessing the I/O device cited is not the external drive since I am able to read files from this drive. 

TIA for any assistance.

Answer 1

Hi,

We'd like to verify a few things in order for us to assist you effectively. Kindly confirm the following:

• Were there any recent changes made to your computer prior to the issue? (Windows update, software or hardware installation?
• Can you access the said drive through Device and/or Disk Management?
• Do you have the latest firmware update of your external drive? If it's outdated, it can reflect the performance of your drive.

Let us know.

Answer 2

Start your Windows in Safe Mode. If this makes the problem go away and you are able to carry out your operation then it indicates that some third-party application may be interfering and causing the issue.

Restart your computer in http://www.thewindowsclub.com/what-is-clean-boot-state-in-windows[***Clean Boot State***](https://support.microsoft.com/en-us/help/929135/how-to-perform-a-clean-boot-in-windows "Perform Clean Boot in Windows") and try to identify the offending item, and then disable or remove it.

If the above didn't help, disable your antivirus software temporarily and see if it makes the problem go away. Some security software are known to cause these issues sometimes.

Let us know how that went.

p.s. Switched removal policy to "better performance"

Answer 4

Safely remove your external hard drive and then reconnect it again to reset their connection. Sometimes, a simple reset will can be the solution.

If that didn't resolve the issue, we suggest you run the Checkdsk.exe tool on the drives that you wanted to be backed up, and on the backup location.

1. Click Start.
2. Type cmd in the Start Search box
3. Right-click cmd.exe in the Programs list, and then click

Run as administrator. Enter administrator password if prompted, or click on Continue.

4. At a command prompt, type the following command, and then press ENTER:

Chkdsk /R X:

Note*: In this command,X: is a placeholder that represents the drive letter of the volume that you want to check.*

5. Press Y when you are prompted to check the disk the next time that the system restarts.
6. Close all applications, and then restart the computer.
7. After restarting your computer,  repeat steps 1 through 4 for the other volume, and then rerun the backup operation.

Let us know how this turned out for you.

Answer 5

changes: Last year Outlook failed and the OS was reinstalled. I restored most things using a previously configured backup. Setting up auto-backups has been neglected 'til now.

access: Device manager reports the drive is working properly. I was able to rename a folder on this drive. Can I assume this verifies write access?

update: I was not aware a USB drive needed updates. I checked and message is driver is up to date.
