Check consistency vmdk file

The raw data is written from 0x on this virtual disk -flat. On the right side of the screenshot, the virtual disk of the Workstation format is displayed and the same data is written from 0x byte number which is not the beginning of the vmdk file. Before you proceed, it is recommended that you back up your data to prevent any possible virtual disk damage.

Perform operations with your disks at your own responsibility and risk. The advantages of these methods are simplicity and universality. After booting an operating system from a DVD media, you can mount the partitions of your virtual disk and copy files from the virtual disk to a USB hard disk attached to the VM or to your host machine, or to any other machine via the network.

Some Live DVD distributions mount disks partitions automatically. This method can be called a legacy method because the principle is similar to copying files from physical disks of physical computers when the installed operating system cannot boot.

Be aware that the operating system booted from Live DVD must recognize file systems of partitions of your virtual disk whose files you want to access. Using additional tools on Windows may help to resolve this issue. There are two NTFS partitions on the virtual disk — one is the boot system partition and the second is disk C. The official Ubuntu 18 installation ISO image is used in the current example. The file name is ubuntu In our example, copying data to the SMB share will be explained.

First, create a directory to be used as the mount point. Then make sure that the necessary files have been copied, and check the contents of your SMB share. As you can see on the screenshot above, the bootmgr file used in this example has been copied successfully.

Now you know the first method of copying the contents of the VMDK file to another location when an operating system installed on a VM cannot boot. This method is similar to the previous one, but a VMDK virtual disk should be attached to an existing virtual machine that has a functioning operating system.

Keep in mind that the functioning operating system on the first healthy VM must be compatible with file systems used on a virtual disk of the second VM that has a non-bootable operating system a VM whose VMDK file you want to attach as an additional virtual disk to extract files.

Power off the VM that uses a virtual disk from which files you want to extract. Find this virtual disk in the ESXi datastore. Copy the virtual disk to another directory on the same datastore or another datastore to prevent an error caused by virtual disk lock. The ESXi host is managed by vCenter. If you use a standalone ESXi host without vCenter, you can use the logics explained in this example — the differences are only in the user interface. Select destination and hit the Copy button to confirm.

In the opened window, select the destination. You can copy the VMDK file to some location on the same datastore or to another datastore. Both vmdk and - flat. A virtual disk can be attached to this healthy VM while the VM is running. Select the copy of your VMDK file that you have made previously. In the current example, the copy of Win-test2. Power on the healthy VM to which you have attached the virtual disk you are interested in, if the VM has not been powered on yet.

Which of the following retains the information it's storing when the system power is turned off? Submit ». Pure Capsaicin. Gary D Williams This person is a verified professional.

Oskar Duveborn Oskar Duveborn Thanks Oskar, that is what we've been doing, moving the data off of it while it is up.

I was curious if there was a supported VMware tool that could diagnosis and possibly fix corrupted vmdk files. Sadly I don't think there's such a tool out there yet, but several recovery services announce their will to help out for a hefty sum pretty much in the style you can get damaged hard disks repaired for your pieces of eight Sign up or log in Sign up using Google.
