Frequently when I am working, my hard disk makes a click noise as if it is powering up/down. The system hangs for a bit and will sometimes recover. After restarting the computer after these events, my hard drive sometimes doesn’t get detected by the computer. Is this a sign of hard drive failure? Could it be my power supply? Thanks for any help.
Before you made some risky action.Here are some advice of mine to you
Have you tried checking chords of your power supply if it is inposition that could attached your hard disk.For me you have a guess that one of the possible cause is your power supply.
something to try: the HDD power cable could be loose or the molex connector (HDD power cable) could be worn / faulty, so connect your HDD to another power connector
BTW: it is unlikely to be the PSU, a clicking HDD usually mean “backup” now
