Anyone any ideas with this one? A brand new Maxtor 250 Gb SATA drive in a new system built by me suddenly started making a really load banging noise (like someone knocking on a door), This was accompanied by a report of a fatal windows error; then it stopped and everything was normal. I have fitted a replacement drive and ghosted the contents across without a problem - bearing in mind that ghost will not work if there is a fault on the source drive. The "faulty" drive has been on test in the wksps using seatools and passes everything thrown at it and no more of the noises - not a sausage! There is no question that it was the drive and no other source Deus ex machina or a ghost in the driveshaft?
