Should i secure erase ssd




















One way to erase SSDs is to use the manufacturer's utilities. Here are some links to get you started. One of the easiest ways is to encrypt the entire drive with a complex passphrase.

On Windows, you can use something like VeraCrypt. On Mac, you can use the built-in FileVault utility, and you're done. No passphrase, no data. You can then format the drive, from which point it should be sterile and ready to accept a reload of the data. If the drive is dead, or you just want to get rid of it in a hurry and don't want a functioning drive at the end of it, then you can take a hammer to the SSD or flash drive.

One thing to bear in mind is that the data in SSDs is held on small flash storage chips rather than large platters, and to securely erase the data, you need to smash the chips. Usually this means taking the cover off the drive before you start swinging. If you're not sure which are the flash storage chips, just drive a nail through all the large chips to be on the safe side. These websites have let their users down the most this year.

It's always difficult to get information from powerpoint slides without narration, but hopefully this will help. However, what you have already done is probably enough, especially given that you believe you don't have any sensitive data on the drive.

What this does is tell the drive that the entire user space contains what's known as "invalid" data. This lets the drive know that it's okay to start erasing these blocks, and so the drive will As the drive sees that it's necessary to erase old data in order to have space ready for new data, it will do so. However, this operation does not take precedence over new data writes from the host, so it's not really certain when the physical erase operations will take place So, beyond some very technical forensic means to recovery old deleted data, it's pretty darned unlikely that someone will be able to recover data from that SSD.

If you do a quick wipe, it only does a metadata change to let you know that there is free space and it can be overwritten. Just like regular HDDs. Even if you write new data on the disk it is most likely stored in another location on disk and simply is referenced from the theoretically overwritten location.

A secure erase only takes a few minutes, so I always do it just for peace of mind, regardless of what was on it. Parted Magic was really cheap and has handled various manufacturers well for me. I was under the assumption that SSD's always write to different cells and are never overwritten, even in a format situation. It's a bit dated, but I think the function in newer revisions are much the same. I use an old bench computer and parted magic for this.

The operating system indexes the file locations in a file system and accesses the data using a mechanical arm. Whereas a solid-state drive is a form of flash memory , like a USB thumb drive—but with a much larger capacity.

Instead of writing to a location on a physical disc, an SSD writes the data to a block. Each write process causes the memory to degrade or "wear. While the SSD uses a file system to communicate data storage locations to the host system, it also re-shuffles the data to ensure even wear across all memory blocks.

Changes made for wear leveling record to a separate file map. In other words, SSDs do not use any physically indexable locations, and software cannot specifically target sectors on the disk. Basically, your computer has no way of telling "where" that information was just copied to. Your SSD constantly moves data around to comply with wear leveling, ensuring all blocks wear at an even rate. What that does mean, however, is that some common secure file deletion methods don't work as you would expect.

At least, not how they work on a magnetic hard drive. Solid-state drives use a specific command to keep on top of file deletion, known as TRIM. In basic terms, this means when you delete a file in your operating system, the TRIM command wipes the space and makes it available for use. The next time your operating system attempts to write something to that space, it can do so immediately.

Simply put, your SSD manages your discarded data. The difference in how an SSD handles data deletion and wear leveling is why regular secure drive wiping programs are not recommended for an SSD.

You will eventually write 1s and 0s to the drive, but it will cause a significant amount of wear to the drive memory in the process. A number of data recovery software packages are available, ranging from freeware to commercial software products.

PartedMagic and GParted listed above include recovery options. Don't store data you want to protect unencrypted on a Solid State Drive; encrypt the whole drive from the beginning. This way, even if an attacker did recover data from the SSD, it would be encrypted and unreadable. If the drive is fully encrypted and there is no worry of the decryption key being used, a simple format will work.

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. This is document aiut in the Knowledge Base.
