My 250gb passport has worked fine for a good while (i think its 2/3 yrs old) it doesn’t get used daily, more once a month if that! Anyway, I was bought a 1TB my Passport for my Birthday, I plugged it in, the drivers installed and it worked fine. Only when I went to plug my older passport a little while later it displayed a message “USB device not recognised” !? Power is getting to the passport, the light is on and I can feel it working if i hold it. I have no idea whether it is broken or its something to do with the new passport!!??
I have (for some unknown reason) managed to use the old passport 3 times since these error messages started! It started up fine, I got all my files off it, I then disconnected it, plugged it back in and I got the “USB device not recognised” message! Anyone any ideas???
