Question about Microsoft Surface Laptop 3

I think that external SSDs should never have incompatibility with docking stations. If there is a problem between the external hard drive and one or more docking stations the problem should not be with the docking station. You should check using a USB key. If it is recognised and the hard drive is not, the problem is with the hard drive (insufficient USB power supply perhaps?). Which docking stations have you used so far? with or without power supply?
