Ummmmmm, no.
>> They do alot of work in conjunction with legal proceedings where one side or the other claims the tapes are unreadable especially obviously when they believe those tapes may not help their case. :) So in these cases not only does their process have to be 100% accurate to be admitted, they have to prove the 100% accuracy. This many times in the face of cross examination by the other side. <<
That doesn't "guarantee" 100% recovery. They can make an attempt, fail, and tell them "sorry we failed but we didn't guarantee shit."
Furthermore a tape can have 90% recovery and still be quite useful in a trial. Hell, it could be just 20% recovered. Have you ever heard of computer forensics of hard drives looking for old data? Sometimes only 1% is recovered and still used in a trial. By your false logic, computer forensics can't exist because it cannot guarantee 100% reliability. rofl
