▶ Part 1. Check disk health

It's a good habit to check disk health regularly to know the general conditions of your hard drive so that you can have enough time to adopt different solutions to various problems that are about to occur. AOMEI software supports S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) to monitor the health of the entire hard drive. You can refer to the following steps to check it.

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 your computer background.  Right-click the target disk, hit "Properties" > "Health(SMART)" to see the state.


Step 2. If you get "Health Status: Good", it means your disk is in a good condition and can be used with confidence. Then you can directly jump to Part 2 to make your disk optimized.


Step 3. If the status is Caution, it refers to 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.


Step 4. If the Health Status shows Bad, it means 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 clone this disk and replace it with a new one as soon as possible.


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.


Note: If the disk is not S.M.A.R.T. enabled or is a virtual disk, 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 via AOMEI Partition Assistant to see if there is a problem with the disk.

▶ Part 2. Optimize Windows 10 disk

If you are told your hard disk is in good mood, it's time to optimize it as it says below to get better performance. Since there are two types of hard disk: HDD (Hard Drive Disk) and SSD (Solid State Disk) , whose working principles are totally different, the latter content will discuss two cases to make sure your hard drive can run normally and successfully after optimization. Both can be done in AOMEI Partition Assistant, the best disk optimization software.

Case 1. HDD

If your disk is HDD, migrating OS to SSD is a popular way to get better performance. Besides, another way to speed up HDD is to perform disk defragment which will save the file access time when reading files. To enjoy this function, you need to upgrade to the Professional edition, the best windows 10 defrag software. With it, you can not only manually defrag your disk in a few clicks, but also enable schedule defrag to optimize your hard drive daily, weekly, and monthly as you like. Below are the steps:

Step 1. Open AOMEI Partition Assistant, all your disks are listed on the main interface. Find the disk you want to defrag (take Disk 0 as an example), right-click and select "Disk Defrag".


Step 2. After that, all NTFS partitions on the disk will be listed. (This function can only run on NTFS partitions currently). You can click "Analyze" to check partition in the first place.


Step 3. Wait a moment, your partition status will be expressed in the form of scores. There are three results:

Normal: Score≥90. The current partition is in good condition, no need for defragmentation.

Suggest to organize: 60≤Score<90. The current partition has some fragments, better to run the defragmentation.

Organize now: Score<60. There are many fragments in the current partition, suggest to run the defragmentation immediately.


Step 4. You can click "Details" to view more information about the results, or you can directly click "Defrag" to begin to perform defragment.


Step 5. When the defragmentation is completed, the partition will be scored according to the defragmentation result.


Notes: You can also click "Schedule" to enable scheduled defragmentation to automatically perform defragmentation on a regular basis.

Case 2. SSD

If you are using an SSD, disk defragment not only doesn't work, but it will hurt the lifespan of your SSD. As for optimizing SSD, there are two workable and reliable methods you can employ in practice. And both of them can be done with the help of the best disk optimizer windows 10 - AOMEI Partition Assistant Professional. Here comes the details.

Method 1. Partition alignment

Aligning partitions should be your first choice if you want to speed up SSD, which is admitted to be the most popular way in improving the read and write speed of SSD.

Step 1. Run AOMEI software. Right-click the partition you want to align and select "Advanced" > "Partition Alignment".


Step 2. In the pop-up window, select 4096 sector from the given list and click "OK".


Step 3. Click "Apply" > "Proceed" to execute the operation.


Tip: Rebooting is required if partition alignment is done to the system drive. Then you can start to experience a faster computer.

Method 2. Securely erase SSD

Since this way will completely erase all the data on SSD and the data are not recoverable, you'd better put it in the last. If you have important data on it, please remember to back up it in advance.

Note: This feature can only be completed on Windows 7, if your computer is not running Windows 7, please unplug it from current computer and connect it with a computer running Win 7.

Step 1. Open AOMEI Partition Assistant, find "Wipe" menu and select "SSD Secure Erase".


Step 2. Select the SSD that you want to erase and click "Next".


Step 3. Read carefully SSD identification information in case of wiping the wrong SSD. Then click "Next" to continue.


Step 4. Then, you will receive the message saying that the SSD is in Frozen state and it cannot be unlocked. In such case, you can unplug the SATA cable and plug it.


Step 5. After reconnecting your SSD, click "OK" to start the SSD Secure Erase. And wait for the process to complete.
