Note: If you set both user+master passwords, you need master password to change user password. Make sure to read the FAQ about other considerations.
don't have luck using just power-USB and combo eSATA+USB combo port on the eSATA/USB 500GB external drive (Fujitsu MJA2500BH G2), the HP HDX won't see it until also add another USB port, which is very not practical, you have reach over the 18.4" screen to get to the other side, it is also slow.
Doesn't work using SIIG ExpressCard/34 eSATA II (based on Silicon Image SiI 3132 SATALink controller driver 1.0.22 8/22/2008) in W500 Windows 7 either, just power and eSATA connections won't get recognized.
Not sure why, but the T510's eSATA/USB combo works just like the instruction siad, does not need the 2nd USB connection.
Becareful about ordering too, for some crazy reason, after ordering, the tracking system and packing slip thinks 57Y4400 is a Wenger Slim Case for Lenovo, good thing they didn't ship that instead from CN via UPS SCS.

Here's the charts for 320GB USB one (the USB cable is built in also) (tested on T61 XP)
