Leaving a drive on all day doesn't normally burn out the motor. There isn't much if any difference in the basic design and materials used when making drives for external versus internal use. In fact, if you buy an external case, it's meant to house a drive that can be bought for internal use. How certain are you that the motor is bad? What are the drive's symptoms. Did you connect it directly to a motherboard port? If the drive has indeed failed within the sealed case, there's not much hope for self repair. You'd need professional services to extract data and this presumes the platters are in reasonable condition. Making 2 bad drives into one is generally limited to swapping controller boards between drives that are already identical.
I have a Internal HD in External case. Forgat and left on all day and burned drive motor out.
Any ideas on restarting so I can recover non backed up data? And I don't need the shoulda kept non replaceable stuff backed up lecture.
Thanks for any and all help.
The drive is WD EIDE. Not under warrenty.
Most is retrievable from other sources, but very time consuming.
I have anouther drive that the bearings are bad in. Is it possible to disasymble both and reassymble the good parts together?
What a think guys?
