Re: Damaged? ProFile Drive Motor

one of my lisas made the sound of a F16 taking off when first plugged in. I the took teh drive out of its cage and put in on its side for a few hours. while the drive was running, it became quieter all the time. I think the oil and greese just melted its way back in to the bearings.

it has been working flawlessly ever since
