Error code -50

Portable Drives My Passport
1

Everytime I try to save a file to My passport, I am getting the following error…‘The operation can’t be completed because an unexpected error occurred (error code -50).’

This problem only started today.

I’m using MacBook Pro with Retina Display OS X version 10.9.2 

Does this mean I should reformat the drive??

Do you have the same issue with all the files or only certain folders?

Check if you can create a folder on the drive.

Try testing the drive on Disk Utility.

With the research I did looks like this issue is related to the files sometimes.

Thanks, I got the problem solved by running Disk Utility.

I have this problem too and can copy files but not folders - which is a real pain as i have loads of folders with files in.

I cannot use Disk Utility as the disk does not show in the list to be able to Verify it or Repair Permissions.

The disk is formatted as it arrived so I guess it must something to do with disk formatting.

howver its worked fine for the past two years??
