There are ways to recover deleted data from the Hard Disk so as to recover any accidentally deleted data but in case you wish to delete data beyond recovery then there are ways to do that as well.
Blank And Secure is a portable tool to securely delete the data. Securely deleting the data is not possible unless you override the data with the zeroes, process termed as “Zero Filling”.
Secure deletion is possible with this program, because Blank and Secure overwrites the data with zeros before deleting making sure that the data is deleted permanently.
Note: Data is deleted beyond recovery, so use the tool cautiously.
