This instructions and video below feature Supermicro SuperServer Bundle 2 equipped with 2 M.2 drives, a Samsung 950 PRO and a Samsung SM951.Yeah, you'll lose all your data on that SSD when you do the Secure Erase I'm about to show you, so to prepare, you'll first want to do a backup (or with VMware, a Storage vMotion of all VMs on that drive) to other storage/datastores. In the detailed walk-through video, you'll see that no Linux skills are required to do this. Next, you'll need to license and download your $9 copy of Parted Magic:įinally, follow along with the instructions and/or video below. want a fresh start between lab re-builds, such as getting ready for vSphere 6.5.want to clean up the partitioning mess that vSAN might have left behind.happen to have a recent Supermicro SuperServer, with iKVM for remote ISO mounting.getting ready to do some of your own informal benchmarks.dispose of sensitive data on any brand of SSD(s) quickly and easily, without having to use various Samsung/Micron/Crucial/Intel tools.This article is just an NVMe update, for those of you who wish to: How to use Parted Magic's Secure Erase to restore performance of your home lab's abused SSDs.Why might you need a fast and easy way to quickly wipe all the data off any brand of SSD including PCIe NVMe and/or M.2 NVMe drives? I covered the SATA version of this back here: If you need to dispose of an SSD and had at some point stored unencrypted data on it, or if the decryption key may have been compromised, you might choose physical destruction.Posted by Paul Braren on (updated on Oct 23 2016) in If the drive is fully encrypted and there is no worry of the decryption key being used, a simple format will work. This way, even if an attacker did recover data from the SSD, it would be encrypted and unreadable. Best practicesĭon't store data you want to protect unencrypted on a Solid State Drive encrypt the whole drive from the beginning. PartedMagic and GParted (listed above) include recovery options. A number of data recovery software packages are available, ranging from freeware to commercial software products. Use data recovery software to verify that the SSD no longer contains data. Verify that the drive has been securely erased If the above methods fail and the data absolutely must be made irretrievable, physically destroy the drive. Contact the drive manufacturer to see if this option is available and enabled. In such cases, you may be able to quickly sanitize the device by deleting the encryption key, which renders the data on the drive irretrievable. Many recently introduced SSDs encrypt data by default. If you cannot locate the manufacturer of your SSD, or if the manufacturer does not provide software for securely erasing the drive, you can try using a generic utility: Use the instructions provided by the manufacturer to erase the SSD. Many manufacturers offer software that allows for securely erasing the drive, as well as other functions such as updating firmware or checking the health of the drive. If possible, use software provided by the manufacturer of the drive to erase an SSD. To securely erase data from a solid-state drive, use one of the following methods: Standard secure deletion tools damage SSDs by performing an unnecessary number of additional writes without being able to tell where the data is written. Wiping programs like DBAN have a hard time identifying all the far-flung data blocks, so they don't do a good job of secure deletion on an SSD. A side-effect of wear-leveling is that a file's data blocks aren't always kept adjacent to one another but could be distributed and disjointed. To address this problem on solid-state drives, manufacturers use wear-leveling algorithms that evenly distribute data among SSD blocks, which means that data is constantly moved around on the drive so the blocks will be worn at an equal rate. This number is typically over 10,000, but it's still possible a user could hit that limit over the life of the storage device. Flash storage has an inherent limitation in that data may only be written to and erased from a given location a certain number of times. To securely erase data, hard disk drives fill the occupied space on the drive with a file consisting of zeroes or execute multiple writes of different characters for more, see Securely wipe disk drives. Standard methods of secure drive erasure do not work with solid-state drives (SSDs). Secure drive erasure is the process of erasing all or part of a storage device so that the data it contained is difficult or impossible to recover. Verify that the drive has been securely erased.
