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?

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 19 years of experience in data recovery.

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.
🔶 VMFS Recovery™ - 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.
🔷 VMFS Recovery™ - 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.
🔶 VMFS Recovery™ - 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.
🔷 What is WMware and ESXi/ESX Server?
VMware is a virtualization system allowing multiple instances of desktop or server operating systems to run on a single physical computer. The desktop edition of VMware runs on top of an existing system (e.g. Windows, Linux etc.), while VMware ESXi/ESX Server is a dedicated operating system that can host multiple virtual PCs without requiring a host OS.
🔶 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.
FAT stands for File Allocation Table. FAT is one of the simplest and most widespread of all file systems. It is supported in all versions of Windows. FAT12, FAT16, and FAT32 are the most well-known of the FAT file systems. (12, 16, and 32 refer to the number of table element bits.)
ExFAT stands for Extensible File Allocation Table. The ExFAT file system has been around since 2006. It is mostly used for SD cards or USB drives. It can be used on these devices as an alternative to NTFS.
RomFS is a read-only file system. It is mostly used for external file storage.
HFS Plus stands for Hierarchical File System. It is a journaling file system created by Apple. It is one of the main file systems for Mac OS.
Ext stands for Extended File System. It is a journaled file system for Linux systems. Ext2, 3, or 4 mean the second, third, and fourth Extended File System.
ReFS stands for Resilient File System. It is one of the new file systems created by Microsoft in 2012. It is believed that ReFS may replace NTFS.
NTFS stands for NT File System. It is the most widespread journaling file system for Windows. It was created by Microsoft in 1993. It has replaced other file systems such as FAT or HPFS.
NTFS 5 is an updated version of NTFS. NTFS 5 was released in 2000.
XFS is a journaling file system. It is a 64-bit high-performance file system that was created in 1994.
ZFS is a file system that was created in Sun by Sun (for Solaris OS). This file system is known for automatic verification of data integrity and protection against corruption of data.
