It it is a windows filesystem just use sdelete -z D: or C:

sdlete comes from sysinternals


that cleans unused space

and with linux
install secure-delete

or better

create a zero file and erase it

after that you have all unused sectors clean

cat /dev/zero > zero.file
rm zero.file

Take attention that before "rm" the filesystem will be 100%
