See if the SSD supports Enhanced Secure Erase. It's supposedMark said:I know that no number of passes ensures actually clearing any
particular page on an SSD, but writing just a bit more than the
total space on the device does work with some devices. 3 passes
of the user view of the space works for most devices. Using
random data ensures something always gets written. Also,
since the programs that I use all eventually have all of the space
that the program thinks it is erasing allocated at the same time,
I know that at least that much space has been erased. 3 passes,
which is almost always more than 2.5 times that actual space,
so the wear leveling stuff will cause almost all of the actual
space to be cleared, but I don't count on all of the actual
cells on the device to have been erased even 1 time.
Anything that I care about is encrypted on the computer and
never gets to the device, let alone the actual flash memory,
in the clear.
to erase all LBAs, even spares.
I really recommend reading the info this guy provides,
since he is the person who promoted the addition of
the command to the ATA command set in the first place.
Included in there, is a description of recovering
drives that are still locked.
There is no point in having commands like that,
unless they "erase stuff" If the erasure doesn't
cover all the storage media, it's no better than
DBAN or equivalent.
