I’ve got my new "My Passport "1GB since last Christmas.
Since Febuary, it suddendly disconnects itself during data-transfer most of the time I try to copy files on (my) PCs. I’ve also tried it on a mac or Linux and there it is the same. (I’ve got Windows7).
Surprisingly, some special files are able to be transferred.
There is no problem to transfer files from computers onto the passport.
Thank you for your help.
