My Passport No longer read by iMac or Macbook Pro

I recently purchased a WD TV Live player and tried plugging my WD 1TB My Passport into the player. The light just flashed and flashed and was never picked up by the player. I later figured out that WD TV Live does not support Journaled drives, and since I use mine for time machine, it wouldnt work.  I then attempted to plug my Passport into my Macbook Pro and the now the drive is not being read there either.  The light on the drive just flashes and flashes but never shows up on my desktop or in finder. I hadn’t used the hard drive in about a week (it sat in its heavy duty WD case on my bed while i was on vacation) so I doubt it was damaged in any way. Could trying to connect it to the WD TV Live have caused a problem? I’m pretty lost right now.

not sure if connecting to the WD TV affected… it shouldn’t

check the drive on disk management… you might be able to repair the partition if corrupted

select first aid and repair disk if possible
