Healthcheck and Bad Sector Prediction

{{ $t('productDocDetail.updateTime') }}: 2026-01-05

Description

Collecting hardware information predicts the bad sectors of the hard disk within seven days. In addition, it cooperates with bad sector scanning to detect and repair bad sectors in time to ensure higher data reliability.

Precautions

  1. Bad sector prediction only supports SATA HDDs of Seagate and Western Digital brands.
  2. Disks under non-virtual datastore do not support bad sector prediction.
  3. The bad sector prediction only predicts if the hard disk will have bad sectors in the next seven days.
  4. After upgrading to a lower version or creating a new virtual storage environment, the bad sector prediction result will not be generated until the environment continues to run for seven days.

Prerequisites

None.

Steps

  1. Navigate to Storage > Summary, and click Storage Forecast to view the disk’s bad sectors.

  1. Click Bad Sectors to open the Bad Sector Details tab, where you can view the progress and status of the specific scan.
