the drives need to be taken apart in clinically clean rooms with a total absense of dirt of any sort at all and when they take it apart they then put the discs into another hard drive to read them

at least that's the basics of what i was told when i had the 30 minute explanation as to why it was going to cost £1200 to get the data back
