Neat little utility, thanks.
A couple of suggestions for a future version:
-- give the files you create an obvious suffix (.ci! ?) -- so if the task
fails for any reason it is obvious what files have to be deleted by hand to
recover the freespace.
-- update the time to complete after writing each file, or add a progress bar.
-- add some sort of unattended mode (perhaps running from a config file) so
people can clean multiple volumes by leaving it running overnight.
And just a few words of caution....
....Completely cleaning a disk volume is not always easy. Data from deleted
files may persist in swap and paging files. Clean-it does not affect that data
....Write heads wobble ever so slightly as they work, so traces of old bits
may remain outside the main track. Someone with enough technology cam read
those fringes and recover data that has been multiply overwritten.
The only real way to be sure a hard drive is unreadable is to use a
sandblaster to reduce it to (physical) bits.
But other methods -- like clean-it.r -- are less messy and may be good enough
for most people.
