Erasing SSD free space

[ajay11]

Is it correct that all free space on an SSD can truly be erased by creating a Truecrypt file container of appropriate size, which gets immediately deleted after creation. Such operation should only add one program/erase cycle to every SSD page, which seems acceptable given their live time of 10,000 or more cycles.

The 'Tasks' icon and then choose 'Wipe Free space'. This will run the Wipe Free Space utility to ensure secure deletion. Wiping free space overwrites everything on the drive that does not contain an active file, including cells that were completely empty.

On an SSD you could just Trim the drive as well.
It marks all empty spots that not actually clear as empty so you can't get anything out of them anyway.
Wiping free disk space on an SSD may or may not clear the cell you hope it will.

There is a whole long story about why suffice to say the SSD's are not HDD's and work very differently internally.

I recommend just emptying your trash can and trimming the drive.
If you REALLY must be 100% sure that all the incriminating evidence is gone use the factory wipe tool from the maker of your ssd. It will be BLANK at that point and you can start over.

Also if you use drive encryption you use that to 100% delete data as well. (another long story on how that works as well.)
