I have been using many types of USB drives for many years. If ever I got a problem reading the drive, I could pop out the drive from the case and use a USB-SATA plug kit to connect it to my PC to diagnose/backup/recover.
However, when I had a problem on a new My Passport I was shocked and dismayed to see it had a proprietary non-standard interface so I could not connect it to my recovery kit. I have come across some non-standard connections before (e.g. Dell) but they usually use a removable adapter - this one seems soldered/permanent on the My Passport so I am stuck.
