Lazesoft Disk Image & Clone vs OSFClone

Lazesoft Disk Image & Clone is Windows software for cloning disks, creating system or disk images, and restoring disks or partitions from those images. Clone an entire disk—including Windows, programs, files, and personal settings—to another disk or partition, using either fast used-block copying or complete sector-by-sector copying. Backups can run daily, weekly, at startup, or on demand, with full, incremental, or differential schemes and automatic cleanup. Options include password protection, compression, file exclusion, and multiple encryption modes. It supports SATA, IDE, SSD, SAS, RAID, and USB disks; FAT, FAT32, and NTFS; disks larger than 16TB; GPT and MBR; and UEFI and legacy BIOS systems. The software also creates WinPE recovery disks, manages partitions, and securely wipes disks or partitions. The Home Edition is free for personal, non-commercial use on up to 3 PCs in one household. Paid plans are listed from 39.99 one-time; command-line backup automation is available only in paid versions.

OSFClone is a free disk-imaging utility that boots from CD/DVD or USB and creates or clones disk images without relying on the installed operating system. It supports raw images and AFF, EWF, and dc3dd formats. The maker says images preserve unused sectors, slack space, file fragmentation, and undeleted file records. Users can compare a clone with its source using MD5 or SHA1 hashes, compress images, and attach forensic metadata such as case and evidence numbers, examiner name, description, and checksum. The product page describes cloning FAT, NTFS, and USB-connected drives. Its listed current download is a 373 MB ZIP for version 1.4.1000; USB installation needs a drive of at least 2 GB. The maker cautions that hardware, driver, and disk-state differences may contaminate evidence, and flags possible superblock changes when ext2/3/4 evidence drives are connected during startup. Some UEFI systems may not boot OSFClone. The software is licensed under GPL v3.0; its images can be mounted with PassMark OSFMount and analyzed with PassMark OSForensics.
