Hi There,


I have a Western Digital My Passport external HDD 1TB.

I have been using it on both Mac OS X and Windows, as that's how I formatted it originally.


Today, my Macbook running 10.7.5 is not recognising the external drive.

When I plug the drive in I can see the power light coming on, so there is power going to it.


It is also working ok on a Windows machine.

I have tried it on different USB ports on my Macbook but it is not working.


I have searched online for updates, and tried to reboot a number of times.


When I last used the HDD on my Macbook I accidentally unplugged it without ejecting it.

When I ejected it Quicktime Player was open & playing a file from the HDD.


I assume this I was has caused the issue.


Anyone got any advice on how I can fix this problem?


Thanks in advance.
