The record

Disk imaging: OSFClone creates or clones exact raw disk images independently of the installed operating system.
Image formats: It supports raw images and imaging to AFF, EWF, and dc3dd formats.
Preserved data: The maker says images preserve unused sectors, slack space, file fragmentation, and undeleted file records.
Hash verification: OSFClone can compare MD5 or SHA1 hashes of a clone and its source drive.
Compression and metadata: It offers image compression and can save case number, evidence number, examiner name, description, and checksum as forensic metadata.
Boot media: OSFClone can boot from CD/DVD or USB flash drives; the listed current download is a 373 MB ZIP for version 1.4.1000.
Compatible drive types: The product page describes cloning FAT, NTFS, and USB-connected drives.
Related tools: The maker says created images can be mounted with PassMark OSFMount and analyzed with PassMark OSForensics.
Integrity caveat: The maker warns that hardware, driver, and disk-state variations can cause a small chance of evidence contamination and recommends using a write blocker when integrity is critical.
Known filesystem issue: The maker reports that imaging ext2/3/4 drives may alter filesystem superblock values if the evidence drive is connected during startup, and recommends a write blocker or hot-plugging after boot.
Boot limitation: OSFClone may fail to boot on some UEFI systems; the maker suggests switching the system boot mode to CSM.
Licensing: The maker states that OSFClone software is licensed under GPL v3.0.
Maker headquarters: PassMark Software Pty Ltd lists its Australian head office at Level 5, 63 Foveaux St, Surry Hills, NSW 2010, Australia.
