Secondary HDD not detected

[aiur]

My secondary HDD is not showing up. I have tried everything the virtual agent told me to do, but it didn't work. Does anyone know how to solve this?

@aiur -- does it show up when connected to a different computer?

After it has been powered-on for a while, is the disk-drive any warmer to the touch than when it is off?

If not, the disk-drive might not be spinning (and generating heat).

Check that the "data" and "power" cables are securely connected to the disk-drive.

hi

HP Pavilion 595-p0084 Desktop PC Product Specifications

Hard drives 128 GB PCIe NVMe M.2 Solid State Drive 1 TB hdd SATA 

if it is this model, are you talking about the original hard drive?
If so, have you had any signs of trouble?

What did you try to avoid repeating the same thing?

you have done tests, result?

Testing for Hardware Failures

Thanks for the response.

Yes, I am talking about the original hard drive: 1 TB hdd SATA.

I don't think there was any sign of trouble. Last week, I started the PC and the secondary HDD was no longer showing up.

I have done tests using the HP hardware diagnostics tool, the results were all passed. The secondary HDD was not detected in that tool so I didn't have a chance to test it.

I am not able to find a different computer to put the HDD on since it has a unique shape of power cable.

The HDD seems not turned on at all. I cannot hear its noise. I have checked the power and data cables several times, but it didn't help.

@aiur  Do you have cable and HDD images both ( computer )?
The HDD  type  SATA must be standard, even if the power cable from the computer is special, the hard drive side must be normal and can be connected to another power supply recent with sata computer  , I have a doubt
But if the hdd is no longer recognized, that it does not seem to be running, it may be damaged
We should be able to check if it does not come from the HP

Not exactly the same series, but quite close it seems to me
we see the power supply cable here, it goes directly to the motherboard, is that it?
but the HDD connector seems normal to me

@aiur -- I am not able to find a different computer to put the HDD on since it has a unique shape of power cable.

Are you referring to a very-old disk-drive, with a PATA (Parallel ATA) interface, with IDE ("integrated Drive Electronics") motherboard, rather than any current HDD / SSD that has a SATA interface?

Is that what you have?
