Need to remove write protection from hard drive
“I have 1TB Seagate external hard drive connected to my computer that Windows 10 is installed on. I failed to copy files on the external hard drive under Windows 10 with a message saying that the disk is write-protected. Remove the write-protection or use another disk. I clicked on “Try Again” button and this error still appeared. I
really need to copy and delete these files to get free disk space on my C drive. I’m
wondering what is write protection on my external hard drive and how to remove write
protection from it in Windows 10?"
