  8. power data recovery says failed to find any file system information from the specified device – that does not work. so much for 'can recover data from a not initialized disk' proof it does not.
    you also seem to forget to mention this only works in the paid for version as the free one cant save anything – but if it does not work and find anything good job I never paid for it or there would be trouble

  9. Hello, I have this 4TB my book external hard drive that shows up on Windows 10 but refuses to be allocated and says "This Device Is Not Ready". I did the mini tool power data recovery and it found 0 files. The drive is seen but not read like it should. It spins like it should but it has a very weird sound. It's not like a click but it's like the reader is moving back and forth at like a 3 time interval every second. I am at a loss for what to do but I do know that the drive may have been dropped at one point. Please, if at any point you see this. Do give the help, it is very much needed for my devices.
