4TB drive has power, but no lights and not visible on home network

FYI, one of the links (My Cloud dead, how to see content on Windows 10?) I posted above does detail a discussion on several methods to access the contents of the My Cloud hard drive that has been attached to a Windows computer. Including using a Linux boot disk and Paragon’s Linux File System driver for Windows. The main advantage to using Linux boot disk/boot USB flash drive/Linux VM or Paragon’s software is one can write to the extracted hard drive. Some (possibly all if I remember right the last time I looked a them) of the programs in that HowTooGeek.com link are read only.

By using Linux one can also restore the single bay My Cloud firmware to the hard drive (existing My Cloud drive or a brand new hard drive). There are a number of methods detailed in this My Cloud subforum to “unbrick” a My Cloud hard drive back to working order (assuming the hard drive isn’t damaged or failed) some of those methods recommend using LInux.
