Abstract In the contemporary digital landscape, standard file deletion (e.g., moving files to the Recycle Bin or using rm commands) does not physically remove data from storage media. Residual data remains susceptible to recovery via forensic tools. This paper examines EaseUS BitWiper , a professional data destruction tool designed to irreversibly erase data from HDDs, SSDs, USB drives, and memory cards. We analyze its underlying algorithms (DoD 5220.22-M, Peter Gutmann), its adaptation to SSD wear-leveling and TRIM commands, and its compliance with the National Institute of Standards and Technology (NIST) Special Publication 800-88 Revision 1 guidelines. The paper concludes that while BitWiper is effective for mechanical drives, SSD sanitization requires verification of cryptographic erasure or manufacturer-specific ATA Secure Erase. 2. Introduction 2.1 The Problem of Data Remanence Data remanence refers to the residual physical representation of data after attempted erasure. Magnetic force microscopy can detect previous bits on a hard disk drive (HDD) even after a single overwrite. For Solid-State Drives (SSDs), the problem is distinct: wear-leveling algorithms and over-provisioning mean that an OS-level overwrite may not physically address all NAND cells. 2.2 Role of EaseUS BitWiper EaseUS BitWiper is a utility software that aims to solve this by offering bootable media (USB/CD) to write predefined binary patterns over user-addressable sectors. It is marketed toward IT asset disposition (ITAD) professionals, organizations decommissioning drives, and privacy-conscious individuals. 3. Technical Methodology 3.1 Overwriting Standards Supported BitWiper implements several known sanitization algorithms. The efficacy varies by storage type:
