Drive spinning but not detected → This usually occurs because of firmware corruption, faulty PCB or damaged read/write heads.

Drive spinning up and down repeatedly → Repeatedly spinning up and down of the drive. It also caused because of faulty read/write heads, firmware failure or a faulty PCB.

Excessive number of bad sectors → Inaccessible of the drive or struggling for read or write data can be caused. It can be indication of Cyclic Redundancy Checking while writing or reading data and drive will repeatedly runs a scan at start-up.
