Hi. I am using secdrive and also PCTools win 2.0 In the disk defragmenter of PCTools, I can choose DOD wipe to clear up free sectors. But I wondered if it wipes the trailing bits and sectors(?) at the end of a file in the end cluster? Is there a standalone utility that would do this end-of-sector cleanup like secure drive does, but that could do it on it's own without the need of any deletion?
