Hard disk failures are generally divided into two types: predictable and unpredictable. The latter happens occasionally, and there is no way to prevent it, such as sudden chip failure, mechanical shock, etc. For predictable situations, if you can measure several important safety parameters of the hard disk and evaluate their conditions through disk monitoring technology, then there will be at least enough time for users to transfer important data to other storage devices before failure occurs.
Modern hardware drives generally support S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology), which can monitor the health of the entire hard drive and will issue a warning when the hard drive is about to fail.
AOMEI Partition Assistant checks the health status of the disk by obtaining the S.M.A.R.T. information of the disk. When the disk health status is poor, the user will be prompted and the disk data can be backed up at this time.
To check disk health
Step 1: Install and launch AOMEI Partition Assistant. When the program is successfully launched, it will automatically obtain S.M.A.R.T. information of all hard disks in the background. When it detects that the disk health status of one hard drive is poor, a red exclamation mark will be displayed on the disk icon. You can right-click on one hard drive and choose Properties-->Health(SMART) to see detailed S.M.A.R.T. information of this disk.
Step 2: There are 3 states of hard disk health.
State one: Good
The disk is in good condition and can be used with confidence.
State two: Caution
Except for temperature, one or more attributes are close to the threshold. The disk still can be used normally, but it is recommended to use AOMEI Backupper to backup the disk regularly.
State three: Bad
Except for temperature, one or more attributes are equal to or less than the threshold. The disk may be damaged soon and cause data loss. It is recommended to use AOMEI Backupper to clone this disk and replace it with a new one.
You can click "View details" to see specific S.M.A.R.T. values, red text indicates that the value of the item is equal to or exceeds the threshold.
If the disk is not S.M.A.R.T. enabled or is a virtual disk, then the disk health status cannot be obtained. You will see a prompt information like this:
In this case, it is recommended to Check Bad Sector by AOMEI Partition Assistant to see if there is a problem with the disk.
