Disk wiping or hard drive clearing can be necessary for a number of reasons such as to install a new operating system or to simply maintain your privacy.
Disk Doctors Data Sanitizer is an ultra effective solution which helps you remove every last shred of data on your hard drive. The reason is that many deletion tools only delete the file structure from your hard drive so you can't see it anymore but in effect, it still exists. Data recovery software can therefore often recover it if needed which is why it's not a particularly safe way of deleting data. Note that Disk Doctors Data Sanitizer aims to eliminate any risk of file recovery so use it with care.
Disk Doctors Data Sanitizer eliminates data files at the heart of directories and shreds data beyond recovery. Disk Doctors Data Sanitizer offers 9 types of disk wiping which include Fast Zero Overwrite (for quick deletes) and Random Overwrite (which scrubs out data repeatedly to ensure it's gone). Disk Doctors Data Sanitizer also offers a series of ultra secure deletions such as "US Navy" and "US Department of Defense" deletion methods which basically emulate those used by such organizations.
Disk Doctors Data Sanitizer is a very secure way to delete data from your drive and ensure that data recovery software doesn't discover anything.
