If you are missing the complete battery pack, then you can power the drive by feeding 6V DC from a PSU (capable of suppling at least 1.5A) into the 2 pin plug inside the battery compartment at the back of the drive. The connector (suprisingly for HP) is a standard part -- a 2 pin mini-Jones connector. Such connectors were used on radio equipment at one time, and a friendly radio amateur might have a suitable socket in the junk box.
If you take the top cover off the drive (4 TX9 screws on the underside), you can see the back of the connector. The red wire is, as expected, +ve.
