Keep errors and bad sectors at bay
Lesser external drives continue to work even when dropped or encounter a shock, resulting in errors and bad sectors. With ADATA’s proprietary shock sensors, all drive activity will cease when a physical shock is detected. Once in the clear, activity resumes. You're kept fully informed with a clear status indicator.
