Data Recovery and Secure Deletion
Solid state drives have set new challenges for data recovery companies, as the way of storing data is much more non-linear and complex than that of hard disk drives. The strategy the drive operates by internally can largely vary between manufacturers and, the TRIM command zeroes the whole range of a deleted file. Wear leveling also means that the physical address of the data and the address exposed to the operating system are different.
As for secure deletion of data, using the ATA Secure Erase command is recommended, as the drive itself knows the most effective method to truly reset its data. A program such as Parted Magic can be used for this purpose.
