I am trying to backup my C drive to a removeable USB drive.At the end, I get the following message---
Info Code 4103--Failed to write to disk
Welcome to our forum. As for this error, please check
1) whether the destination partition where you save the image file isinsufficient of disk space or not.
2) Verify the destination is accessable and you have sufficient read/writeprivileges.
3) When you are doing the backup operation, you may shut down any other windowswhich are accessing the directory where you save the image.
4) Check if there are bad sectors on the destination partition. If there arebad sectors, you may recreate the image and save it to another healthy place.
