WD My Passport X not in drivedb
As the title says, the WD My Passport X is not in the drive database. To make it work it needs only '-d sat'.
Attached you can find the output of 'smartctl -x', the relevant dmesg output and lsusb output in case it is needed.
There are already two regular expressions in the database that could be extended to include this disk, but I don't know if you'd prefer to create a new entry for this model so I have not attached any patches.
