Even "simple" recoveries are expensive.
Sounds like you're tarring all DR companies with the same brush. From your previous posts I reckon you'd be the first to complain that people are making assumptions based on unfounded prejudices!
That's why people opt for DIY.
No, it's because of interweb based DIY drivel and misguided information making people believe they can freeze their 1.5Tb seized Seagate to miraculously recover their data for free, and keeps their valued $$$ out of the clutches of those nasty "scum of the Earth" DR firms.
The last feedback I received in this forum was from a user who was quoted US$700 to remove a shorted diode.
I doubt that very much, more like the client was given a "guesstimate" on a recovery price, sight unseen. Then either it DID turn out to be a TVS problem (and probably given a "proper" quote accordingly), or you/they are just ASSUMING it was so simple. Again, you are just scaremongering to add fuel to the "fleecing DR company" fire you seem to like fanning.
As for frying the preamp with a misplaced solder blob, perhaps you could elaborate. I find it very hard to accept anything that the data recovery profession says in this regard. ISTM that there are some who will do or say anything to dissuade people from even the simplest of DIY jobs.
Again, paranoia rearing its ugly head. Assuming that ALL DR companies are robbing bastards and out to squeeze as much $$$ out of every poor unspecting "punter".
We would charge approx £99 for a TVS fix, but this would include re-applying the diode, AND cloning the drive to a known good one in case of bad sectors which are likely to have developed if the drive blew while powered on. You think that's daylight robbery no doubt as we are "seed of Satan" pro DR company, and that we should do it for $10? Sorry, but we're not a charity.
