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.

Famous quotes containing the words data, recovery and/or secure:
“Mental health data from the 1950’s on middle-aged women showed them to be a particularly distressed group, vulnerable to depression and feelings of uselessness. This isn’t surprising. If society tells you that your main role is to be attractive to men and you are getting crow’s feet, and to be a mother to children and yours are leaving home, no wonder you are distressed.”
—Grace Baruch (20th century)
“It’s even pleasant to be sick when you know that there are people who await your recovery as they might await a holiday.”
—Anton Pavlovich Chekhov (1860–1904)
“The moles nested in my cellar, nibbling every third potato, and making a snug bed even there of some hair left after plastering and of brown paper; for even the wildest animals love comfort and warmth as well as man, and they survive the winter only because they are so careful to secure them.”
—Henry David Thoreau (1817–1862)
