Item delivered on time. Unfortunately, a lot of wasted time later: This disc was intended to replace a failed system drive (a WD 10 years) but by the formatting phase, it was not easy and it took multiple times when formatting. Then the Windows installation was impossible, every reboot resulting in new resettlement. I have verified that the problem was much disk attempting an installation on an old disk recovered on an old machine. Successful installation the first time. So ... back to the sender and reimbursement by Amazon smoothly.
