It identifies defects that can result from component wear, and repairs or isolates them to protect the data. When enabled, S.M.A.R.T. protects against system downtime and possible loss of productivity and data by communicating reliability status to the user. Data Lifeguard is always enabled, and works independently from S.M.A.R.T. to provide a self-tuning capability. Background Data that is stored on hard drives can represent vital company or individual records, important project information, essential client and employee records, critical tax information, historical records, graphics, etc. Risking the loss of such data that often takes years to accumulate is not a viable option in today's marketplace.
Hard drives featuring the highest reliability are a vital imperative for every computer system user.
Western Digital's exclusive new Data Lifeguard feature helps provide the utmost reliability attainable in preventing data loss on hard drives. All user sectors on the hard drive are scanned during times of inactivity from the host. Sectors requiring extended retries to recover are rewritten and read back to ensure the storage integrity of the sector. If read back performed is still less than optimal, the sector will be relocated to a new good sector. Data Lifeguard is always actively guarding data, even if S.M.A.R.T. operations for monitoring and predicting hard drive performance are disabled.
