I have to say that I have the same problem with the 1Tb drive, but not with any of the others… Why did WD elect to change it…? I just have to breathe on mine and the drive resets itself and we start all over again - not what you need on a drive for portable off site backups of a server… Cable also seems to be stiffer than the previous ones, so more likely to cause a problem at the connection.
I love the Passport Drives - brilliant, but in this instance I feel more than a little let down!
