IsoBuster 4.3 Beta Released!

December 04, 2018

I'm very happy to announce the Beta release of IsoBuster 4.3.

This version features full support for the XFS file system. Exploring, extracting, finding missing files and folders etc.

I retired my old Buffalo NAS and as it used XFS as file system, the time was right to implement XFS in IsoBuster. My new Synology NAS uses BTRFS as underlying file system. If I can find good documentation for it, BTRFS will be in one of the following IsoBuster versions I'm sure.

But that is not all. As usual there are plenty of improvements, a few fixes and other new functionality, such as dealing with RAID and LVM data structures, WBFS and so on.

Changes / New:

  • Full support for the XFS file system
  • Recognition and support for RAID 1 structures inside a partition, to find the file systems within
  • Recognition and support for LVM (Linux' Logical Volume Manager) inside a partition, to find the file systems within
  • WBFS partition support. Shows what images are stored in a WBFS partition
  • Open *.wbfs files and show the images that are stored in the file
  • Support for 8KB (8192 bytes-per-block) devices such as Plasmon UDO2 drive etc.
  • Introduction and use of *.1Kn, *.2Kn, *.4Kn, *.8Kn, ... file extensions for disk images of drives with higher than 512 bytes per sector


  • Improved detection of the proper block size in image files based on partition and file system data
  • Optimized HFS Partition parsing to deal with both native-blocksize Partition Map entries and 512-byte Partition Map entries
  • Implemented DICOM signatures in finding files based on their signature (Found during a scan for missing files and folders)
  • Create a UDF File system when we have a valid VRS, AVDP and VDS. Even when the FSD is absent. So that the user knows there's at least UDF present
  • Make sure the UDF VRS sequence also works on higher-than-2K-sectors when VRS structures are located in their own physical block rather than every 2K (For instance: Plasmon UDO2 drive with 30GB UDO disk vs. MS UDF on 4KN drives)
  • Open Image file drop functionality now also works when a file is dropped on the ListView (right pane) or breadcrumb control (top)
  • Implemented work-around to still load FAT (on USB sticks for instance) when the first x bytes of the BPB have been erased (by an unknown process / application)
  • Support format *.s01 again (disabled in previous version) after extensive testing to confirm that it works
  • Show "Managed Clone", not just "Managed Image File" where and when relevant. Changes in various screens and dialogues
  • Repaint TreeView icons if hovered over, to update the object's status (should it have been expanded already during a different process (e.g. Search))
  • *.dd images are now always treated as 'not optical' (to avoid loading as optical (tracks / sessions) if nothing meaningful can be found inside)
  • Ability to always confirm the destination drive of a managed clone
  • Show the destination drive in the managed image clone completion confirmation dialogue
  • Improved progress dialog when creating and completing managed image files / clones
  • Improved Managed Image File and Managed Clone Properties dialogue
  • Ability to suppress write error messages (OK to all) during the making of a managed image file or clone (for instance when completing on demand on media that is not big enough to hold the full range)
  • Make sure write errors, during the creation or completion of a managed image file or clone, are marked as bad sectors, even though the read on the source media was successful
  • Implemented "Limit:" keyword for search, so that the search can be limited to 'limit' count of matches (for instance *|Limit:10 )
  • Added command {%SELF} to the export functionality to also include information of the target file system itself (for instance to display the root's extents)
  • Added command {%DATETIME(NA)=EMPTY} to the file export functionality to return an empty string instead of "N/A" on objects with an invalid or missing date-time property
  • Added tag <%TAB> to the file export functionality to easily add tab characters to the output
  • Plenty of other improvements, changes and re-writes in the core code / engine, as this is a living project and to deal with the ever growing new functionality
  • Various other GUI improvements


  • If IsoBuster is started idle, without auto-selecting a drive, attaching or removing a drive doesn't change that state anymore
  • Fixed exception error when displaying a popup menu without any drives present or selected (under certain conditions)
  • Improvements in time and date display because negative second values are possible in Unix / Linux file systems
  • Do not abort on empty GPT partition table entries, continue checking instead (finds more partitions in some cases)
  • Fixed {%LT} and {%ISO8601} leaving a "}" character behind in an exported list
