The driver detected a controller error on \Device\Harddisk1\DR3.

In Windows 10 64-bit, I went to Event Viewer saw this error:

The driver detected a controller error on \Device\Harddisk1\DR3

I looked in Computer Management > Disk Management, but not sure which drive the error message refers to.

I would run a chkdsk /r on all the drives, but this 5TB drive would take over 3 days to complete a chkdsk /r. If indeed this external caused the error message, I want to make sure.

Yes, it's the disk number as displayed in Disk Management. Alternatively, there are many ways to check it on command line.

  • PowerShell:

    Get-PhysicalDisk | Select DeviceId, Model, SerialNumber

    "list disk" | diskpart

  • cmd.exe:

    echo list disk | diskpart

  • any command interpreter:

    wmic diskdrive get Index, DeviceId, Model, SerialNumber

Commands using diskpart need to be run in a terminal launched as Administrator.

It clearly says which disk it is. \Device\Harddisk 1 \DR3, so it is referring to Disk 1.

The DR3 part at the end is some kind of identifaction to which partition it is referring.

Do note, a controller error is not like bad sectors though. Chkdsk may make the drive become permanently unavailable. You should take this warning and start doing backups.
