Data Eraser Utility
Disk wiping is beneficial for privacy, because files are not completely deleted using
operating system's default delete function. In most of the file systems, delete
function consists of marking the space occupied by the file as free and updating file
system allocation structures, leaving actual file contents intact on the storage media.
If there is continuous read and write operations on the drive after deletion,
eventually this space will be assigned to other files and would be overwritten.
However, if there hasn't been much of read and write operations since the file was
deleted, data recovery software or disk forensic tools have a good chances of
retrieving deleted data in chunks or in whole by accessing the disk drive.
So normal 'delete' command or deleting data from the recycle - bin is not a safe method
for data removal.
To securely erase we need to follow certain patterns or standards for disk
sanitization, the patterns used for overwriting are mentioned below and are available
to effectively remove magnetic remnants from the hard drive.
HDRC Data Eraser Utility is designed to do the same job. Data Eraser Utilities securely
wipes and removes all deleted confidential data from your hard disk drive and removable
media including pen drive, smart card and more. Permanently deletes most recently used
application of Microsoft word, Power point, Excel, Access records and similarly
