Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable. New flash memory -based media implementations, such as solid-state drives or USB flash drives , can cause data erasure techniques to fail allowing remnant data to be recoverable.
A number of storage media sets support a command that, when passed to the device, causes it to perform a built-in sanitization procedure. The following command sets define such a standard command: ATA (including SATA) defines a Security Erase command.
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
External hard drives offer massive storage for all your digital memories. My favorites are small, portable drives with no moving parts called SSDs, or solid-state drives. ... Storage capacity ...
The SSD controller will use free blocks on the SSD for garbage collection and wear leveling. The portion of the user capacity which is free from user data (either already TRIMed or never written in the first place) will look the same as over-provisioning space (until the user saves new data to the SSD).
Data remanence is the residual representation of digital data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage media that allow previously ...

The TRIM command enables an operating system to notify the SSD of pages which no longer contain valid data. For a file deletion operation, the operating system will mark the file's sectors as free for new data, then send a TRIM command to the SSD. After trimming, the SSD will not preserve any contents of the block when writing new data to a ...
