Looks like that one is also searching through some blogs. Get's more results that way, but less accurate results. This is a custom search I put together myself. I don't know where that other one came from.
Yes, think of it like an organ donor. Only not the organ donors in civilized nations who wait for the people to die first before harvesting their organs. We're more like the black market organ dealers who kill the subject because we suspect the part is a match for the patient we're trying to heal. Fortunately they're just hard drives we kill as donors.
@jol, it was a feeble attempt at humour. As a novice, I haven't done many HSA swaps but would have no hesitation in re-using donor heads if they were not obviously destroyed by patient media damage--which I understand is a common occurrence with DM series drives. But I could be wrong.
We specialize in data recovery from failed hard drives and RAID arrays among other professional data recovery services. This forum is dedicated to the sharing of information related to the field between other professionals. Our belief is that we are all more successful if we share our knowledge rather than try to keep it all locked up as a secret.
