Clonezilla Live, free and open-source disk cloning and imaging software for system backup, recovery, and deployment, has released its latest stable snapshot, v3.3.1, based on Debian Sid, with the Linux kernel updated to v6.18, and Partclone to v0.3.45.
A major highlight is expanded support for 4Kn (4K native) and 512n/e disks. The release adds mechanisms for cloning between mismatched sector formats, allowing 4Kn-to-512n/e and 512n/e-to-4Kn migrations. NTFS handling is improved by correctly updating the Total Sectors field.
Moreover, a new utility, ocs-pt-512-4k-convert, enables conversion of partition tables from 512B to 4Kn layouts. The GPT expansion tool ocs-expand-gpt-pt has also been rewritten to detect sector mismatches and perform conversions when needed.
On the security and encryption side, a new mechanism allows changing the master key directly from a LUKS header. BitLocker support is refined, with improved functionality for the clone server (ocs-onthefly) and better password retry handling. Plus, the system now enables the “-edio” Direct I/O option in the TUI by default and limits certain options to non-x86-64 architectures for safer defaults.
Several internal tools were rewritten or enhanced. The firmware listing tool now retrieves data directly from kernel modules. Additional metadata files, including fdisk.list and blkdev.json, are generated in the image directory to provide more detailed disk information. The live environment now includes the lsb-release package. Time synchronization can be disabled with the ocs_time_sync="no" boot parameter.
Regarding bug fixes, the release resolves multicast failures when cloning partitions with unknown filesystems by switching to partclone.dd when necessary. Issues affecting extended partition detection on MBR disks, MTD/eMMC device restores, PTUUID-based device discovery, and partition order errors during network cloning have been addressed.
Finally, improvements were made to terminal rendering, device information parsing, and name collision handling during device conversion.
