I would like to use a brand new WD external enclosure formerly an 8TB Easystore with another brand’s 4 TB SATA hard drive.
With the other brand HD installed and connected to my Mac with a 3.0 USB cable, I am not able to initialize this drive. Mac OS Disk Utility sees the drive as unmounted 8TB Easystore media even though it is a 4TB Toshiba drive.
The Toshiba drive was previously used in a 2-bay external enclosure (Elite brand from New Egg) in a (hardware) RAID 1 set up for Time Machine backups. I did not format the drive before removing it from the RAID enclosure.
The error message I get is:
Unable to write to the last block of the device.
Operation failed.
