Vmkfstools Command for directly working with the (virtual) disk at host level. With this command you can destroy whole virtual machines if you do not take the right precautions (hint: BACKUPS) and are not familiar with the command.
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?
Using vmkfstools to import converted VM? 10 posts hutchingsp. Ars Tribunus Angusticlavius Registered: Sep 2, 2001. Posted: Mon Feb 11, 2008 12:48 pm. This gives us a 36 GB size (while the VM itself actually uses about 10 GB). Issue the command vmkfstools –punchzero VM.vmdk. This will take a while so be patient (and oh yes, you VM must be powered off). On a 40 GB VMDK it took me about 10 minutes, but this will depend mostly on your SAN speed.

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.
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 15 years of experience in data recovery.

Since that time, thousands and thousands of successful repairs have been done. Recover VMFS files is easy now!
Recovering VMDK Images on vSphere, ESXi/ESX ServerVMFS 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
- Download and install VMFS Recovery software™ on your notebook, desktop or server computer running Windows Vista, 7, 8 10 or Windows Server 2003-2019
- Run VMFS Recovery™ and select a target object.
Then choose between:
▶ Fast Recovery Mode (try this first)
▶ Full Recovery Mode. - 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.
- You then get read-only access to files for the purpose of preview and verification of success.
- 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.
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
- Make a request for Guided Repair Service to get a free consultation and clarify the terms of recovery by the DiskInternals team.
- Follow the instructions provided by support services.
- 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.
- You then get read-only access to files for the purpose of preview and verification of success.
- 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!
VMFS disks can be recovered on damaged, corrupted and inaccessible physical hard drives and
RAID arrays, including corrupted RAIDs and broken arrays with or without the original RAID controller installed.

Frequently Asked Questions
🔷 VMFS Recovery™ - 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 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.
