thanks - is that overkill for me though? All I want to do is make the disk "new" again so that I can install a fresh completely new copy of windows for the entire disk. (I had several partitions that now I just want to get rid of and run several OS's in virtual box)

So, the zero's is overkill for me right, or would you advise to do it? Would it make the disk more error-free?

Thanks
Lister,

If you were going to be selling or giving your SSD to someone, then you would want to use the Clean all command to also include a "secure erase" to make sure that the data is gone off of it.


However, since you are keeping the SSD and are only reinstalling, then "Clean all" would be overkill and do a bunch of unneeded overwrites (unneeded wear and tear) to your SSD. For what you are wanting to do, the Clean command will work perfectly. :)
