In research that has important findings for banks, businesses and security buffs everywhere, scientists have found that computer files stored on solid state drives are sometimes impossible to delete using traditional disk-erasure techniques.
Even when the next-generation storage devices show that files have been deleted, as much as 75 percent of the data contained in them may still reside on the flash-based drives, according to the research, which is being presented this week at the Usenix FAST 11 conference in California. In some cases, the SSDs, or sold-state drives, incorrectly indicate the files have been "securely erased" even though duplicate files remain in secondary locations.
well the 1st thing I think of would be to remove the SDD controller and have one for "forensics" that does not start this process. As long as you don't power on the drive with the OEM firmware the data isn't going anywhere.
