DoYourClone for Windows vs OSFClone

DoYourClone for Windows has no write-up on Specifiction yet; its figures are above.

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.
