Newbie here. Unsure if it's an HDD issue or PSU issue.

I've been dealing with this laptop hard drive I'm using for my desktop. It's been making noises like clicking and beeping, followed by freezes, but usually moving it slightly fixes it. Until today I thought it was clearly the hard drive.

About 30 mins. ago when turning the pc on the hdd starts beeping constantly and it won't go past the bios screen. Opening up bios shows the hdd has not been recognised.

Therefore I unplug the sata cable from the disk, and the beeping turns into a fast clicking. Plugging in another sata cable brings back the beeping. It still isn't recognised.

I conclude the noises are not caused by the sata cable, so I unplug the power cable from the drive, the beeps stop, and I plug in the power cable from the cd drive (I don't have it connected to the cd drive though, it's hanging loose). Suddenly, after plugging that one in, there are no beeps, no clicking, just the normal sound of a hard drive.

Reboot, and the PC works like a charm. SMART always tells me the drive is in good condition. Temperature is fine, nothing's below threshold. So it might not be drive, I'm taking a guess at the power supply. What do you guys think?

  1. If the drive works fine on the other power cable, and you ran a disk check utility on the drive to check it, then there is a good chance there is something wrong with the power cable you were using the first time.

    Possibly, I have in the past changed the power cable to try and fix the beeps and it didn't solve the issue, but the difference yesterday was changing it while the pc was turned on, which somehow stoppéd the problem.

    Is that relevant? Any way to check if the power supply is failing?
