  • Completely new NTFS and ReFS Recovery engine, build and tested for recovery of large scale storages. Now it's able to detect and correctly sort physical or RAID disks with deleted NTFS or ReFS partitions that were stored lots of virtual machines with guest Windows disks. Earlier such NTFS over NTFS were recovered only in cases with correct partition table.

  • Automated update check. A lot of customers asked to add a check for update. Developers have added it. Update checks if installed version is up to date, determines if new version is compatible with product key and warns if new release is beyond free upgrade period. Of course update can be turned on or off anytime you like.

  • Updates in VMFS
  • Updates in EXT

VMFS Recovery™ 4.5.65 update

  • Fixed critical bug. VMFS Recovery™ experienced a failure when a disk or flash drive was extracted from the system during recovery process. Links to data scanned for other drives became corrupt even if extracted disk was not involved in recovery process.
    We strongly recommend to update.

New release of VMFS Recovery™ 4.5.34

  • Contains minor fixes and improvements.

VMFS Recovery™ is available to download:

  • Contains a lot of critical fixes that was tracked and fixed with previous released our new bug track and report module.
  • EXT fixes and improvement
  • XFS fixes including corrupt large file error (Files over 512Mb saved as corrupt)

New release of VMFS Recovery™ is available to download:

  • Added a LVM hybrid RAID support, where disks may have different size. Used in Linux OS and on NAS devices.
  • Added module to track anonymous usage statistics and bug reports. Details
  • Lots of minor bug fixing and stability improvement thanks for a new bug tracking module

  • VMFS Recovery™ is available on site:

    • Extended support of detectable HP RAID 6 arrays up to 22 drives.
    • A lot of changes in detection of LVM arrays. Extended detection range and capabilities.
    • Fast detect algorithm in RAID Wizard improved in speed and quality of detection. We do our best to minimize brute force enumeration.
    • RAID initialization at startup received a set of new signatures and capabilities. Even more reconstructed RAID arrays right after start up!
    • RAID Wizard checks selected configuration by user and extended range of disks in a set, adding +1, +2 and deducting -1 disks in array. We have discovered that many customers select existing number of disks instead of original, when one (two) of the drives fails. Setting applied for RAID 5 and RAID 6 arrays correspondingly. Deducting a disk from the set could be required if customer adds a spare disk to the set. Which is also not required, but happens.
    • New signatures from Dell arrays are added to recognition. We have discovered new Dell RAID mapping at one of the remote recovery cases. It's somewhat similar to HP RAID 5R, which is similar to RAID 5, but uses its own structure and array signatures. We do not support these new Dell's arrays yet, but now we can recognize them.
    • Added support for a new group descriptor in VMFS 6
    • Fixed minor issue with VMFS 6 disks over 16Tb capacity
    • Added NTFS, ReFS and VMFS deduplication support for Pro and Ultimate licenses.
    • Added support for cluster sizes up to 2MB in NTFS disks.
    • Improved speed of scan and processing of large number of folders and files on EXT disks. Previous version has opened folder that contains several million files in Reader mode: 18 hours, new version opens it in 30 minutes. Uneraser scan improved from 2 hours to 30 sec on test cases.
    • Interface texts updated to ensure in proper and safer guidance during data recovery processes.
    • Added "Drives -> Create Images for All Storages", an advanced disk image creation tool. It allows creating disk images from multiple drives with specified offset and size from beginning or end of the disk. A more detailed guide for this new feature will be released soon.
    • Added detection of China's Dahua file system
    • Added several GUI hints, warnings and descriptions to ease usage of VMFS Recovery™
    • Installation script updated
    • Added support of large blocks (64+ kb) in NTFS

    • Bug Fixed: incorrect file operations on VMFS 6 disks that led to display and save healthy VMDK files as corrupt ones. Because of the severity of this bug we strongly recommend to update.
