I recently replaced my failing hard drive with a Samsung 840 SSD (500GB) and wanted to replace the Superdrive with a new 1 TB HGST Travelstar hard drive.
After putting in the SSD and restoring from a time machine backup, everything seemed to work fine.
However, after putting the hard drive in, I couldn't find it under "Devices", probably because it wasn't formatted. I wanted to use Disk Utilities to format it. I tried the method with the "Erase" button as well as the "Partition" method, but every time I tried, a window would pop up telling me: "Unable to write to the last block of the device."
I called the manufacturer of the hard drive and they told me it might be the hard drive itself. So before I'm sending it back, I wanted to know if it might be something else. Can anyone help me?
