determining pin-outs of dc motors

[system]

I have a disk drive motor, NIDEC DLC-312, with a 5 lead connector. I have contacted the vendor and the motor does not show up on their site and the vendor says the specs are proprietary and not available (come on, its from a 12 year old SyQuest EZ135 cartridge drive).

Does anybody know anything about this motor or motors of this kind (from disk drives)?

Is there a decent documented way to test such motors to determine the configuration of their power and sense leads so they can be used with a driver shield?

First action is to get a multimeter and measure the winding resistances between every pair of wires - I think this motor is 4-wire, 1 wire is connected to the metal frame?

This should then suggest how things are connected internally. It is perhaps a star-wound 3-phase motor?
