USB HDD stopped being seen through USB HUB, why?

Question

Hard disks

Hello. Help with advice please, there is a Transcend USB 2.0 disk, USB HUB Transcend USB 3.0 with additional mains power and a laptop with USB 3.0. Everything worked perfectly, the disk was plugged into one of the hub inputs, peripherals (mouse, keyboard, usb dac) were plugged into the other inputs. Everything worked perfectly. This morning I discovered that the disk is not visible in the system (the light on it is on, but it does not make noise at all, it is not visible anywhere in the system (Device Manager, Disk Manager)). Nothing changed in the system and did not install (I use a constant small set of programs). I tried to poke it into another input on the hub, I tried to leave only it (the hard drive), without the rest of the peripherals, I tried to delete all devices associated with usb (even hidden ones) from the device manager, nothing helps. Directly from usb works great. I checked the power supply from the 220v network, changed the sockets, everything is the same. Other devices in the same hub ports work.
Tell me, what could be the matter? Where else can you do something so that the hard drive starts working from the hub again?

Answer 1

It is likely that the power sags when the load is connected. If the hard one does not spin up, then it just does not have enough power. Replace hub or cable or reduce line length. Perhaps this is the reason

Answer 2

there is not enough power to spin up the screw, probably try another usb cable.
