I was told there was a hard disc drive HDD problem, but 'hopeful to extract files', then it was, 'cannot do, becos mechanical failure, needs new HDD $400'. Got new HDD. Got it back, but mouse and printer would not operate. I went and asked for old HDD, was given it grudgingly & with no real assurance it was mine! It was: local expert retrieved my files and fixed issues. HDD did not have mechanical failure at all! (Probably corrupt files/bad sectors). Wrong Diagnosis! Or ?? Very poor communication from Tower IT. No explanation or apology. Would not recommend.
