Having pulled several of these drives apart and 'cured' (hah) them, I don't think it's a lubricant problem (tho it could be). Essentially what happens is that the spindle motor is unable to spin up with the heads in their resting position. If you move the resting posiition out a few millimetres (eg by the judicious application of some heatshrink around one of the magnet pillars) the drive becomes useful again. Whether this can be explained by 'bad lubricant' is somewhat doubtful, as the spindle motor's in a better torque position with the heads in _further_, rather than out... >| Tom Wilson | "I can't complain, but sometimes | -- # mike smith : miff@apanix.apana.org.au - Silicon grease monkey # # "The question 'why are the fundamental laws of nature mathematical' # # then invites the trivial response 'because we define as fundamental # # those laws which are mathematical'".
