- Doo-doo happens... This seems to be the "preferred" method that hard
- drives use to fail; I've found that a drive that won't mount is generally
- the first sign of trouble, with no warnings before that. Humidity could in
- fact be the problem; we often have a drive fail for the first time on a
- day with a sudden change in humidity. On some drives the increased humidity
- can apparently cause the lubrication in the drive to thicken up.
-
- Often the problem is stiction; the drive simply can't spin up, because
- the heads are stuck to the platter. First see if your drive is under
- warranty; there may also be a warranty extension program in effect for
- your drive. If you are comfortable opening up the Mac and taking the drive
- out, you could try shaking it (like a paint can, rotate it rapidly in your
- hand); that might free the heads, if stiction is a problem. You might also
- try rapping it (not too hard) on a padded surface. Sometimes a drive will
- just suddenly start working again a day later. If you get it going, leave
- it running until you do a complete backup; as on a plane, the most risky
- points of the flight are during takeoff and landing; not much happens once
- you are moving.

- Assuming you can get it to mount, it should be easy, but once a drive has
- failed on me I treat it as untrustworthy and back up much more often. If
- the problem is electronic rather than physical, sometimes the HD setup can
- re-install the driver and mount it, or a utility program can. This only
- really applies if the drive is physically functioning, but the contents are
- somewhat corrupted. Proceed with care...
