Warning: If your hard drive emits unusual noises (clicking, grinding or metal scraping), turn it off immediately! This symptom typically indicates a head crash that can destroy your data. Hard drives spin with extreme speed - from 7,200 to 15,000 revolutions per minute - therefore extensive damage can occur in a short period of time. Contact DriveSavers immediately, as this situation demands professional recovery in a Cleanroom environment.
