Multiple HDDs in a RPi5 vanish

Hey, I'm really stumped by this issue so perhaps one of you folks might be able to help me out here. I run a little server on an RPi 5.i got for another project originally. So ce I cannot finish said project due to time constraints, I repurposed the thing into a little server. It's running smoothly so far with one really weird exception. Whenever I attach more than 1 HDDs to the pi and use at least 2 at the same time, both HDDs will start to fail, unmount and the whole USB hubs I connected them to will just disappear from LSUSB. Originally I thought this was a power issue but the weird behavior continues when I connect each HDD to it's own powered USB hub. I'm really at a loss as to what's happening. Any ideas?

Problems with spinning HDDs on RPI are common. Possibly even on powered hubs they may spike more than rpis 1.2A USB max allowance. You may need a specialised hat, or better to switch to solid state storage?
Thing is that I got the HDDs lying around already. The hub supplies 5v/3A so powershould not be an issue... Yet who knows... I could try to power the HDDs from a USB power supply with a split cable and see if that helps
Might be power. i had a 3.5 HDD external USB adapter with separate power plug. It would drop out under sustained use. Fix was providing higher amp power supply
