See the System Event Log for more information.4 Conclusion What Is the “Windows Was Unable To Complete The Format” issue? However, after the "Format fs=ntfs quick" I get the following error:

The 3TB Seagate Barracuda hard disk drive should now show up in Windows Explorer when you open it.

Note: Performing this operation against the hard disk drive will erase it.Īt the DISKPART> prompt, type "CREATE PARTITION PRIMARY" to create one partition which occupies all space on the Seagate Barracuda hard disk drive.Īt the DISKPART> prompt, type "FORMAT FS=NTFS QUICK" to format the newly-created volume with the NTFS file system.Īt the DISKPART> prompt, type "ASSIGN" to assign the disk volume the first available drive letter.Īt the DISKPART> prompt, type "EXIT" to exit the DiskPart program, and then close the Command Prompt as you normally would. One of these should show up as a 3072 GB hard disk drive (or thereabouts).Īt the DISKPART> prompt, type "SELECT DISK n" where n is the number of the Seagate Barracuda hard disk drive.Īt the DISKPART> prompt, type "CLEAN" to wipe the beginning of the Seagate Barracuda hard disk drive. Open an elevated Command Prompt (filename: CMD.EXE) and type "DISKPART" and then press Enter to start DiskPart.Īt the DISKPART> prompt, type "LIST DISK" to get a list of drives recognized by the operating system, ordered by number. Have you tried using the command-line DiskPart utility? Here's what you would do: Windows cannot complete the format using the format tool. I don't care about any of the data I just need to reformat it. I have a 1.5tb Seagate external USB hard drive that was corrupted after being undocked incorrectly.
