All data recovery companies, regardless of skill, unanimously say that if the memory chip of a device has just a hair line crack, data recovery is impossible. Not unlikely, not expensive, but impossible. One company even stated that even the FBI can't retrieve the data. Is this true?
Why is this? I find it hard to believe if just a tiny section of an extremely common chip has a tiny crack, all of the data is completely gone.
I would have thought someone talented person somewhere would be able to patch up the area of the chip and get some of the data back...
Is it something to do with the charge? I know flash memory uses transistors to store its ones and zeroes in the form of an electrical charge. If the chip is cracked, do the transistors "short-out", turning them all to zeroes, something like that? Is the data gone rather than irretrievable?
