"While we know that tire shops apply weights to the wheel in order to balance the tire, a comparable technology for unbalanced platters is unknown.
The only technology possibly capable of overcoming this problem is Magnetic Force Microscope (MFM) photography, since this technique does not require the platter to spin. However, MFM requires scanning the whole surface of the platter. The MFM moves from region to region, each region yielding a picture. This alone will take several months. Then all these pictures must be stitched together. A 20GB hard drive consists of 160,000,000,000 bits, probably 300,000,000,000 bits including overhead. Each bit is represented by a magnetic flux change. A picture displaying this flux change will probably use 100 bytes, thus inflating each bit by factor 1000. You will have to analyze the amount of 40 Tera byte of data. It is unknown if this technology is in use. It certainly is not 'commercially available and affordable' because a data recovery would cost hundreds of thousands of dollars."
