Health warning is reported when calculated health drops below the 70% threshold
This article applies to:
Acronis Drive Monitor reported the following alert for one of the disk drives monitored:
Disk health warning detected
If Acronis True Image Home or Acronis Backup & Recovery software is installed and has a backup task scheduled on the event of failing hardware, this task will be triggered automatically when this status is reported.
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 represents them as drive "health" between 100 and 0%. (See Acronis Drive Monitor: Disk Health Calculation).
Health warning is reported when calculated health drops below the 70% threshold.
The health warning status is generated by Acronis Drive Monitor as aggregated status of S.M.A.R.T. parameters rather than directly reported by the drive. This approach allows Acronis Drive Monitor to generate early warnings about the drive electromechanical problems, rather than only relying on the S.M.A.R.T. "failure predicted" condition which may not happen at all or happen when the data is not accessible already (see "Drive failure predicted" Status Reported by Acronis Drive Monitor). Although most drive manufacturers report S.M.A.R.T. parameters in a consistent way, S.M.A.R.T. standard itself does not define how exactly this data is reported. While the best efforts to support every manufacturer are made, some miscalculations are still possible. Known health reporting issues are listed in Acronis Drive Monitor: Known Issues in Disk Health Calculation.
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.
However, quick worsening of these problems over the time is an indicator of serious defects on the manufacturing stage, and may lead to the drive failure in near future.
Therefore, for a drive with health degradation reported, the following actions may be recommended:
- Make sure you have a recent backup. Regardless of the drive health, fresh data backup is the only reliable way to avoid unexpected data loss;
- Check your drive against the Acronis Drive Monitor: Known Issues in Disk Health Calculation, to eliminate health miscalculation by Acronis Drive Monitor;
- For mission critical systems, consider the drive replacement;
- For other systems, ensure that you backup regularly, and monitor for further health degradation. See How to Monitor Drive Health Degradation Over the Time in Acronis Drive Monitor;
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%.
