The driver detected a controller error on \Device\Harddisk1\DR3: which disk corresponds in Computer Management?

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.

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

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.

  Its somekind of identification to which partition it is referring. And yes, it appears to be your 931GB drive. 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.
