Not that much frankly for new major(4.0) version.
Quote:
Kernel
-Some User Interface enhancements.
-Profile handling improved.
-Utility start with parameters added(actions to perform on utility start: do not read ID, perform SW/HW reset)
-Ability to cancel search in database added.
Universal utility
-Verification test optimized.
-Customization for Read/Write/Verify tests.
Samsung
-Terminal baud rate increased to 128000
-Handling track defects optimized.
-Terminal baud rate adjusted automatically on start-up.
-Added families: STORM2, TRIDENT3.
-Defect list handling improved for some families.
-Utility start menu revisited.
-Reading by CHS mode exported to Data Extractor.
-ROM writing for Delphi and Poseidon families implemented.
IBM-Hitachi
-NVRAM adjustment algorithm implemented for SATA drives(search beginning address of SA with non-original NV-RAM)
-Password reset algorithm made easier(no testpoints shortening required)
-Custom families handling improved to use with NV-RAM adjusment algorithm.
-Further Data Extractor integration(some utility functions exported to Data Extractor to provide more reading and error/timeout handling capabilities).
WD Marvell
-LDR loading redesigned(to start drives that get hung and do not ID at all).
-ROM restoration mode added for ROYL drives. Allows to rebuild ROM based on HDD SA or SA resources.
-Cancel button on utility start(to stop utility initialization in case the drive hangs).
-Module reading-writing improved.
-Factory self-test added.
-Working with module copies improved.
-Internal hardware way of checking modules added in "Modules directory" and "SA Structure test" modes.
-Error handling improved.
-Readable vendor-specific errors reporting implemented.
Seagate
-Some specialized commands are now exported to be used by Data Extractor to facilitate imaging drives with bad media: loading App, Ovl0, Cert.
-Ability to modify App code to prevent drive from starting "offline scan" during imaging. Greatly improves imaging speed on drives with degrading media/heads.
-5400.3 family(VENUS) added.
-Further Data Extractor integration(some utility functions exported to Data Extractor to provide more reading and error/loss handling capabilities).
Maxtor
-Loader loading algorithm optimized for Sabre2, Sabre, N40PSATA families.
-Hardware translator regeneration implemented (by the drive itself - much faster than software regeneration)
-Software translator regeneration algorithm optimized.
-Autorecovery mode using LDR implemented.
-SA structure report improved.
Quantum
-Modules table reading algorithm improved.
-Further Data Extractor integration(some utility functions exported to Data Extractor to provide more reading and error/loss handling capabilities).
Fujitsu
-Further Data Extractor integration(some utility functions exported to Data Extractor to provide more reading and error/loss handling capabilities).
Data Extractor
-Filter view implemented to display only needed files in Explorer view based on file mask.
-NTFS and HFS+ handling minor improves.
