Sorry to hear that your harddrive crashed. The same happened with me as well recently. If your TR came with a toshiba harddrive then yes that’s the correct part number, however if your TR came with a hitachi harddrive you’ll need a hitachi harddrive since they use different interfaces. If you aren’t sure then you’ll have to remove your harddrive to check. I did the same in my case (wasn’t 100% sure that I had a toshiba hdd).
