If you have an HP device that used the original full-height Sony drives (HP9122, HP9123, HP9133, HP9114A, Integral, etc), then you MUST strip down the eject mechanism and regrease it. If you don't there's a very real risk that it won't latch up properly and when you try to eject a disk, the upper head will catch in the disk and be ripped off its mounting.
The only cure for that is to replace the head carriage assembly and do a full alignment. Needless to say this is a lot more work...
Basically, you take the drive out of the machine and remove the mounting brackets. Take off the top cover (1 screw), the logic board (3 screws and connectors), the front panel if fitted (it isn't in the Integral), then the eject damper (1 screw, rear left of the drive), the head load solenoid/bracket (2 screws) and finally the disk holder itself (4 screws).
That then comes apart by removing 1 more screw and slipping off the E-circlips. Clean off all the old grease using a suitable solvent and apply a _trace_ of new grease. Put it all back together.
One other point: High density disks do not work in these drives. Not only is the coercivity wrong, but the disk-inserted sensor lines up with the HD-detect hole, so it's not operated. The result is that the drive thinks it doesn't have a disk installed.
