are you a linux user ?Do you like to find a windows native "dd" alternative for zero-fill a drive?
In order to delete both used and free disk space I have used commandline SDelete sysinternals utility, here are the steps:
- Download Sysinternals SDelete , and unzip the archive
- If your drive is unformatted and has not a drive letter, do a quick ntfs format of all drive (and mount it as drive X: , for example)
- open from command prompt, cd into download folder use this command: Sdelete –s -z X:\*.*
And then you have simply to wait for the wiping to complete.
Explanation: -s, recurse subdirs; -z, zero fill free disk space;
default is -p 1 which means only one pass
WARNING: Deleted data in unrecoverable, PAY ATTENTION to the drive letter!
