How to Erase SSD before Selling in Secure and Complete Mode？
Get an old SSD and want to sell it? What you have to do before selling is to erase SSD. Find secure methods from this page.
SSDs are of great popularity among computer users. People use them as the primary drive for operating system, frequently-used programs and personal data. Some people even have more than one SSD and are in need of selling one of them. At this time, what comes first is to delete personal data. You may already know that “deleting” does no help in this case. There are two probable methods: erase SSD or format SSD. Which one is better?
1. Erase SSD
Erasing SSD is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on an SSD by using zeros and ones to overwrite data onto all sectors of the device. As a result, the data is rendered unrecoverable.
2. Format SSD
Formatting SSD is a process of cleaning data to prepare an SSD for initial use. A new file system can be generated in the process. However, some or most of the cleaned data might be recoverable with special tools.
Now you see, to make your personal data unrecoverable, you should choose to erase SSD before selling.
SSDs store information on microchips and contain no moving parts whereas HDDs record information on a storage platter by moving a mechanical arm with a read/write head over a spinning platter. In addition, SSDs rely on an embedded processor and interconnected flash memory chips while the platter inside HDDs is coated with a magnetic media.
Thus, a degausser has the ability to permanently erase a hard disk drive but it proves ineffective at erasing data from a solid state drive. How to wipe SSD before selling securely? Please move on to the next part.
Here are two secure methods to wipe SSD before selling that I’d like to introduce:
Most manufacturers supply software for their SSDs in order to update firmware and perform tasks like secure erase. Here is a brief list of such utilities people often use: Intel Solid State Toolbox / OCZ Toolbox / Corsair SSD Toolbox / Samsung Magician / SanDisk SSD Toolkit.
However, those utilities only apply to SSDs of the same manufacturer. Is there a kind of software that is effective for all the SSDs? The answer is YES.
AOMEI Partition Assistant Professional is such partition software which can work as a professional erasing tool. As its new feature “SSD Secure Erase” is only usable in Windows 7, you have to connect the SSD to be erased to a computer of Windows 7 operating system. Then, you can securely erase SSD before selling within several steps:
Step 1. Install and launch AOMEI Partition Assistant. Click on “SSD Secure Erase Wizard” in the left pane.
Step 2. Choose the disk you are going to erase from the list. You can double click the chosen disk to check specific information in case that you erase a wrong one.
Step 3. In the pop-up window, you’ll find the SSD is under a frozen state which is set to ensure no one can modify your drive settings. Perform a hot swap to disable this restriction.
Tips: How to perform a hot swap?
First, open computer case (rear cover or drive shell) and find the SSD you’ll erase.
Second, unplug the power cable and then disconnect the SATA data cable from SSD.
Third, after a few seconds, reconnect the SATA cable to the SATA port and then plug the power cable back to finish the hot swap.
Step 4. Now, click “Next” to start wiping all data on SSD securely and completely. The erasing process will take a short time.
Once the wipe operation is carried out by AOMEI Partition Assistant, the data can not be recovered by any data recovery software. Please back up all the important files and data before you do.
AOMEI Partition Assistant is not a file-level wipe software but a sector-level one. So you can only use AOMEI Partition Assistant to wipe partitions or disks. After a partition/disk has been wiped, all the files on it will be erased simultaneously. If you do need to wipe a specific file, then you have to download a file-level wipe software.
AOMEI Partition Assistant is your best choice to erase SSD before selling in secure and complete mode. You may enjoy more powerful features with it, such as disk conversion between MBR and GPT, OS migration on GPT disks, Windows 10/8 To Go, etc.
