My passport for mac,on iMac running yosemite

Just purchased 1Tb wd my passport and am having difficulties,backup fails every time and complete drive test cancelled,any ideas?


Make sure you have the drive plugged in directly to the computer, avoid using any USB hubs since it may be causing power issues. Also if you are using a desktop computer try connecting it to the back USB just for troubleshooting purposes.

Thanks for that,i’m plugged straight into imac,Ive managed to back up my computer but cant retrieve any data,when i try to retrieve it says “cant open application because it is a time machine backup”


Are you using Time Machine to retrieve the data?
