I connect my 3TB external hard drive to my MBP, but it failed to appear in Finder or on the Desktop. Plug out and reconnect it, nothing changes. I run Disk Utility and it finds an invalid volume header. And Disk Utility can't repair it. It can't be read or mounted. How to repair invalid volume header error? Please help!
Invalid volume header error
Invalid volume header is a fairly common and relatively serious problem. Invalid volume header error can be caused by many reasons, such as forced power off, virus attack, improper operation to the Mac or hard drive. When we face the invalid volume header error, the failed hard drive can't be read or mounted, and Disk Utility may cannot repair invalid volume header error even though it proceeds "Repair Disk" successfully.
