Description

What is S.M.A.R.T.?

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is a disk monitoring technology which is available on the most modern hard drives. Acronis Drive Monitor analyzes a number of S.M.A.R.T. attributes, and shows them as drive "health" which may be between 100 and 0%.

How health is calculated in Acronis Drive Monitor?

Health calculation algorithm is described in Acronis Drive Monitor: Disk Health Calculation.

Why the drive health may be below 100% level?

Most brand new drives will have 100% of health initially. However, it is not uncommon for a drive to develop few minor defects over the time. These defects would be detected by S.M.A.R.T. and reported by Acronis Drive Monitor as health degradation.

Usually these minor defects do not pose significant threat to the data safety, and the drives with some health degradation signs may be safely used further. Until the 70% “warning” health threshold is reached, the drive health will be reported in the "green" zone.

An alarming sign would be a quick worsening of these problems over the time, as it may be an indicator of serious defects on the manufacturing stage, and may lead to a complete drive failure in the near future.

Therefore, for a drive with health degradation reported, the following actions may be recommended:

Usually drives with health degradation will not be covered by the manufacturer warranty, not until the "failure predicted" status is reported and the health drops to 0%.

There is no direct way to improve the health of your hard disk. It is normal that the disk will experience wear and tear over time: HDD is a mechanical device that constantly runs when the computer is turned on, and SSD drives have a limit on the number of write cycles to any block.

To prevent losing the data on disk, it is strongly recommended to have current and total backups of your system and important data. For more information on backup and recovery software by Acronis see Acronis backup and recovery solutions.
