ts, most probably for that statement, ms assumed you're using ssd with full disk encryption hehe. in general, for ssd with trim enabled, you can use the reset to wipe data on it. if you think it's not enough, you can always use manual format command with /p (number of pass) to format your drive first. (i think this is available since w8.x):

format <drive>: /p:1

you can use this manual format command to hdd also. probably with /p:3. (i think it works the same as dban in some extent)

the problem with secure erase like this is that it takes a very long time to complete. the better way is to use full disk encryption like bitlocker from day one. you can just perform a quick format on encrypted disks/partitions and that's good enough.

edit: in the case of using bitlocker, you can use gpedit.msc and bump up the default encryption level to a stronger one, if you want.

oh. drive wipe from ccleaner works fine too.

yeah a simple reformat is never enough. i have recovered data due to own carelessness many times. usually the recovery worked very well for plain disks without encryption.
