Sometime on Jan 20, jtd assembled some asciibets to say:
Find a similiar drive and replace the controller. It works many a times. Or deep freeze the drive. Grep the list. There is a thread where Philip has described the procedure in detail.
Use an air tight freezer bag, put the disk in, squeeze out as much air as possible, seal and freeze overnight. Make sure you're ready to transfer the data out the next day.
When you take the drive out of the freezer, make sure it's dry. Sometimes moisture trapped in the bag condenses onto the metallic surface. Dry what you can see, wait for a few minutes and plug it in. It should last a couple of hours after this. This procedure cannot be used too often.
