Your hard disk failure is typical. At first, it was a bad hard disk failure, so I remind you to format it. If the power is on all the time, the bad track of the hard disk will be more serious, and even the head will fail. If you still want to recover data, please do not perform any power-on operation. The hard disk itself cannot be repaired. If you want to recover the data, you should find a professional organization like 5 1Recovery.
