I’m in need of some help please! This might be a bit long, just want to tell you what steps i’ve taken so far. I bought a 2TB WD Passport last week. Plugged it into my MacBook Pro (2009), reformatted for Mac use and everything was fine…
4 days later i plugged it back in with the intention of using it as extra storage. It appeared on my desktop, i had a message about using my password and keychain access… and then it dissapeared. Light on the passport was on the minute i plugged it in then turned off. Unplug and try again in other USB port - same thing. Unplug and try again, no keychain message, the drive starts up and i open the window to drop files on - then it all dissapears again. Its like i am pulling the plug or something… (i’m not, honest!)
So at work i plug it into my macbook (2014) and its fine - asks for password, stays on the desktop, just as you would expect. So the Passport and USB cable are working fine.
Next step then, i updated my home OSX to El Capitan. Plug Passport back in, different window now (no keychain password question but password software which is on the drive) Passport stays on the desktop for around 20 seconds (a new record!) and then it shuts down and dissapears again. This time i get the ‘Drive not ejected properly’ message which is new. Now i’m not ejecting it - for some reason my mac is. Gahhh!! WHY!?!
So the Passoprt is fine, the USB is fine, my USB ports are ok (in that they recognise there is something there) the problem clearly lies with my mac, but the fact that it does recognise the passport but takes a dislike to it for some reason is confusing.
Can anyone help? I can reformat the disk at work and try again but that seems futile as i have already established that the drive is not the problem. Any thoughts? The only thing i’m thinking is that there’s not enough power in the usb port to sustain the passport (although you usually get a message saying that) Am i missing anything else?
Thanks in advance!!
