You only did a 'Format Quick' which only re-writes the partition tables. I will continue researching on how to wipe my data completely (I know that formatting just recreates the partition table, and doesn't remove the actual files), but I'm curious whether the 35 zero-write will harm an SSD in any way. My question is, can a 35 zero-write wipe harm an SSD? No, I'm not going to destroy the actual SSD, since that'll be a waste of money, and the fact that I've already sold it for a fairly handsome price. There's rumors that just a single format will do it, but I've tested this and my drive-recovery software was able to find the files after the SSD was formatted. I wouldn't normally bother with this secure-erase, but the drive contained classified high-security software files of my own creation, and I really do not want anybody else to gain access to the information.

I know that the 'toughest' wipe that can be done is a 35 zero-write military-grade 'nuke', which essentially wipes the data on the drive 35 times over.

I recently sold my 128GB Crucial M4 SSD (I have a much larger capacity OCZ SSD, which is faster), and need to wipe the drive.
