Strategy for replacing a LENOVO U31-70 hard disk drive

Always try to run a low-level format before replacing a LENOVO U31-70 hard disk drive. This will cause all customer data on the hard disk to be lost. Make sure that the customer has a current backup of the data before performing this action.
Attention: The drive startup sequence in the computer you are servicing may have been changed. Be extremely careful during write operations such as copying, saving, or formatting. If you select an incorrect drive, data or programs can be overwritten.
