Replace it with an SSD ? The rubbish down at this level, is all roughly
the same, but PNY is an actual reputable brand. PNY make video cards too.

There is PWDIS. A five wire power cable inside a PC, can trigger PWDIS
on its own. A four wire power source for SATA, lacks 3.3V and allows
a HDD to spin up. But not all drives necessarily obey this. It would
depend on what SATA feature level the drive claimed it was compatible with.
I don't think I have any drives here, that would listen to this trick.

The BIOS in a Dell, usually includes a control per SATA port
if you can find it. But its behavior is a lot more confusing
than any regular retail motherboard. The Dell has some pretty crazy
ideas about RAID, and it is the RAID enablement that puts making
BIOS changes off the rails (the BIOS thinks RAID works in pairs,
and perhaps pairs of ports appear or disappear in the interface,
best guess).

I have one Dell here in my collection, but the problem is, I
don't have a monitor for it. Since I had a PC mobo failure here,
I no longer have a convenient setup for swapping PCs out and
testing ones from the junk room. I don't have table space, for
even one more PC.

I think one user, reported a drive which refused to spin up.
I think they were seeing the PWDIS feature in action, and I gave
them the details. And as thanks, they never reported back so
we'd have a field confirmation. That was an 8TB drive, and size
seems to be a factor as far as "identifying drives that might have it".
I very much doubt your 1TB drive has this feature.
