Having problems with your
virtual environment?
VMware boot image corrupted?

Need to recover VMDK file?
vSphere: Unable to read partition?
Are you afraid of the complete loss of your data?

Everyone is! And there are so many different ways to lose it. The most common reasons that lead to data loss on VMware virtual machines are:

  • Physical drive issues: an unexpected failure of the disk during use, or there is a pre-existing defect
  • RAID array corruption: in the moment of a blackout or because of a hardware malfunction
  • Software failure: due to conflicts with other software, including drivers or bad software updates
  • Attack from malicious software
  • Human error, like occasional deletion of system files

A lot of things may happen. But you know what?

You can feel good now...

What is VMFS and VMDK?

VMware ESXi/ESX Server uses its proprietary file system called VMFS to format a physical partition on a hard drive. Virtual disk images representing virtual PCs are stored on VMFS partitions as files in VMDK format.

DiskInternals VMFS Recovery™ is a VMware recovery tool which offers a safe, easy way to recover information stored on VMFS-formatted disks. Like any other storage media, VMware disks can get damaged by software and hardware faults. Bad blocks and physical corruption of hard drives storing the virtual disk images can also cause corruption of VMware VMDK images.

These companies believe that their data is very important.
Do you?

When you are working with virtual disks and virtual machines, it’s important to make a backup of all the data you have there. Otherwise, it can be complicated or even impossible to recover data from the VMFS volume after the failure, and that’s why it’s better to take care of your valuable data beforehand.

Nevertheless, in the case of damaged or corrupted virtual machine, or if VMFS volume is not mounted, there is still a solution. DiskInternals VMFS Recovery ™ software recovers all the data that can technically be restored in case of the logical corruption of virtual disks.

Virtual machines and virtual disks data including the VMFS metadata can be recovered with the recovery software by DiskInternals that has more than 14 years of experience in data recovery.

Recovering VMDK Images on vSphere, ESXi/ESX Server

VMFS Recovery™ is VMDK recovery software, that can provide access to healthy and corrupted virtual disk images used by VMware vSphere, ESX/ESXi Server.Recovering VMDK images on ESXi/ESX Server is a two-step process. First, VMFS Recovery™ repairs ESX/ESXi storage to gain access to VMDK images.Then, necessary VMDK images are extracted and the usual data recovery process is launched.

Step by step instructions

How to
recover files easily:
  1. Download and install VMFS Recovery software™ on your notebook, desktop or server computer running Windows Vista, 7, 8 10 or Windows Server 2003-2016
  2. Run VMFS Recovery™ and select a target object.
    Then choose between:
    ▶ Fast Recovery Mode (try this first)
    ▶ Full Recovery Mode.
  3. VMFS Recovery™ automatically examines the current state of VMware VMFS datastores, volumes, disks, RAID (if used) and reads VMDK images as well as VMFS structures where this is possible.
  4. You then get read-only access to files for the purpose of preview and verification of success.
  5. When you are confident that your data is in place, please purchase a license for VMFS Recovery™ to get access to files or to export selected files.
Remote Online Recovery

VMFS data recovery is possible remotely. VMFS Recovery™ retrieves data online over a network. Physical access to the server which hosts virtual PCs is not required. Thus, there’s absolutely no need to shutdown the host computer/server or access hardware directly

How to
repair deep damages:
  1. Make a request for Guided Repair Service or call 1-347-474-8601 to get a free consultation and clarify the terms of recovery by the DiskInternals team.
  2. Follow the instructions provided by support services.
  3. The DiskInternals team manually examines, in detail, the current state of VMware VMFS data stores, volumes, disks, RAID (if used), and reads internal structures of VMDK and VMFS in the best possible way.
  4. You then get read-only access to files for the purpose of preview and verification of success.
  5. If you do not retrieve any valuable files with Guided Repair Service, you are welcome to request a refund for the VMFS Recovery™ license. If necessary files are in place, congratulations!

Frequently Asked Questions

  • VMware boot image corrupted?

    Let's understand when the boot image gets corrupt. The truth is, ESX Server stores the boot image e on a separate partition that is not available to anyone. When the server boots it creates a RAM virtual disk and copies the image when it is loaded from the RAM. The boot process includes a couple of image integrity checks, which virtually eliminates the boot image corruption. The problem usually occurs after a new hardware or updates are installed.

    • If you have changed the ESX server configuration and after this, you have a boot image corruption, you need to check is the hardware.
    • If you haven’t change the ESX server configuration, but some updates were installed - reinstall ESXi Server.
    • Keep in mind, that the faulty RAM modules or slots can cause the boot image corruption too.
  • ESX Server datastore not visible?
    • ESX Server can be invisible for the reasons of hardware or software failure. It can happen because of the human factor, physical corruption or malware.

    What to do? Check a configuration of the server, keep in mind the probability of hardware bugs. During the check, follow VMware instructions strictly.

  • VMFS datastore inaccessible?
    If VMFS datastore doesn't mount - you can correct the problem with CMD or you can do it with DiskInternals VMFS Recovery ™ software. For VMFS Recovery™ it doesn't matter if VMFS datastore is mounted or not. Through the SSH connection, DiskInternals VMFS Recovery™ software shows if the datastore is mounted.
  • VMFS volume not mounted?
    The recovery process can be done anyway. In case VMFS volume doesn't mount - for VMFS Recovery™ it doesn't matter if VMFS volume mounted or not. When you enable SSH, DiskInternals VMFS Recovery™ software shows the datastore, even if the VMFS volume is not mounted.
  • VMDK file not recognized?
    Typically, this problem occurs when the file’s description is missing. In fact, VMDK file consists of 2 files: a small text file-header(handle) and a large binary file, which contains the description data. Some users forget about a small handle and use only the binary file, that’s why ESXi Server does not accept it. To resolve this problem, you can create new one VMDK-disk in ESX Server with the file name you need. To finish the process, you need to delete a big VMDK-file using the console and put in its place recovered one.
  • Need to recover VMDK file?
    If the VMDK file is no longer on the disk, you need to run VMFS Recovery™. A scanning will check the possibility of VMDK file recovery and show you the result. Using the trial version, you can mount recovered VMDK (mount with menu “Expert=>Mount as a disk”, and don’t mount in the system) and preview file's content. This manipulation allows you to be sure of the integrity of the recovered data without making a purchase. If everything is fine you can go further and restore your information.
  • vSphere: Unable to read partition?
    This is the common problem, which occurs when the disk has damaged 0 track or the partition table. This does not meet the standards of MS-dos, that’s why the problem happens. A solution has two options. If it is a new disk - you need to overwrite the partition table. In case it is an existing disk - select the disk, make the image, mount an image in the VMFS and start the scanning process.
  • ESXi could not read volume header?
    That problem can be in case the section is formatted or completely broken. Solution: scan VMFS Recovery™ in Uneraser or Recovery mode. Your problem is most likely to be solved in the next hour.
