Windows 10: External SSD not detected in some USB ports

Hi,
I have a new external SSD disk (Samsung T5) formatted in NTFS. The problem is that the disk is not detected when I plug it in some of my USB ports. When I plug it, the LED of the disk is on but Windows does not detect the disk. This happens on different PCs (laptops, desktops).

UPDATE:
It looks like this is happening when I'm using an USB extension cable.

PC -> SSD works
PC -> 2m USB 2.0 extension cable -> SSD works
PC -> 2m USB 3.1 extension cable -> SSD does not work



Any tips how I could debug this?

cheers

I believe the problem is that the cable is not providing enough power to the SDD

My Seagate external hard drive is not detected when plugged in to USB port of my laptop using windows 10?

Thanks for your response.

I have tried all the steps provided, however in vain. The external hard drive is not identified at all in any of the the USB ports when connected. The USB ports identify other external Flash drives and devices. However this drive is detected in another laptop
using Windows 7 OS. Please advise further.

Regards

 

External Hard Drives Won't Work on Two Specific USB Ports

I should note that one drive is a USB 3.0 external hard drive while the other is a USB 3.1 external solid state drive. Both are being plugged into only USB 3.0 ports. The two ports that don't detect the external HDD and SSD will detect regular USB thumb drives.

No, I have not tried different cables. However, the cables and drives work fine in other USB 3.0 ports either in the back or the front.

Nothing is listed in Disk Management.

These are getting power from the USB ports. The external HDD's LED turns on but does not spin. In other ports with the same cable, it does. The external SSD lights up too but the storage doesn't seem to be detected unless plugged into another port.

As stated above, all ports are USB 3.0.

There are no errors in the Device Manager.

Based on the questions/answers being given here. It sounds like there may be a power issue with the two USB ports. Do thumb drives and external drives have different power requirements?
