Theses S.M.A.R.T hard drive self-tests can help you detect and replace failing hard drives before they cause permanent data loss. However, there's a couple issues with `smartd`:
These S.M.A.R.T hard drive self-tests can help you detect and replace failing hard drives before they cause permanent data loss. However, there's a couple issues with `smartd`:
- There are more than a hundred S.M.A.R.T attributes, however `smartd` does not differentiate between critical and informational metrics
- There are more than a hundred S.M.A.R.T attributes, however `smartd` does not differentiate between critical and informational metrics
- `smartd` does not record S.M.A.R.T attribute history, so it can be hard to determine if an attribute is degrading slowly over time.
