Secure, reliable and cost effective data erasure solutions to erase data permanently beyond data recovery scope at end of life cycle of IT assets such as PCs, servers, rack mounted drives, and smartphones. Today organizations need tamper-proof erasure reports to prove successful erasure and comply with legal auditing requirements.
Data erasure (sometimes referred to as data clearing or data wiping) is a software-based method of overwriting the data that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by using zeros and ones to overwrite data onto all sectors of the device. By overwriting the data on the storage device, the data is rendered unrecoverable and achieves data sanitization.
Ideally, software designed for data erasure should:
- Allow for selection of a specific standard, based on unique needs, and
- Verify the overwriting methodology has been successful and removed data across the entire device.
Permanent data erasure goes beyond basic file deletion commands, which only remove direct pointers to the data disk sectors and make the data recovery possible with common software tools. Unlike degaussing and physical destruction, which render the storage media unusable, data erasure removes all information while leaving the disk operable. New flash memory-based media implementations, such as solid-state drives or USB flash drives can cause data erasure techniques to fail allowing remnant data to be recoverable.
Software-based overwriting uses a software application to write a stream of zeros, ones or meaningless pseudorandom data onto all sectors of a hard disk drive. There are key differentiators between data erasure and other overwriting methods, which can leave data intact and raise the risk of data breach, identity theft or failure to achieve regulatory compliance. Many data eradication programs also provide multiple overwrites so that they support recognized government and industry standards, though a single-pass overwrite is widely considered to be sufficient for modern hard disk drives. Good software should provide verification of data removal, which is necessary for meeting certain standards.
To protect the data on lost or stolen media, some data erasure applications remotely destroy the data if the password is incorrectly entered. Data erasure tools can also target specific data on a disk for routine erasure, providing a hacking protection method that is less time-consuming than software encryption. Hardware/firmware encryption built into the drive itself or integrated controllers is a popular solution with no degradation in performance at all.
Secure Data Eraser is a solution to keep your computer privacy:
- wipe files and folders;
- wipe disk drives and flash memory;
- Wipe unused disk space.
Secure Data Eraser overwrites data in either fast or secure erase algorithms with multiple passes using overwrite patterns designed to achieve military-strength security.
Secure Data Eraser erases files completely, so sensitive information CAN NEVER BE ACCESSED OR RECOVEREDusing any data recovery software or even in a special data recovery laboratory.
