How to preview recovered *.VMDK file before purchase

Let’s imagine that you were successful and scan resulted in VMDK file you need. The folder looks just like it was before failure or deletion, all files are in place and their size is bigger than 0kb.

However, it’s data recovery and often file name, icon and size isn’t enough to make sure in recovered data integrity. This is why we’ve added an advanced built-in preview functionality so you can make sure that data recovered correctly and your files are just fine.

This operation works smoothly if you try to preview JPEG or DOCX file, but it’s a bit more complicated if we talk about VMDK file. It’s preview will be displayed in HEX mode and only a few people would recognize in the following screen NTFS disk:

We admit that it would be frustrating to check integrity of recovered VMDK file in such HEX view, as well as it’s pointless, because VMDK file is actually a disk image. Thus you can mount recovered VMDK file by right click and selecting “Expert->Mount as Disk” command.

Now you should check “Hard Drives” section of the disk list and look for partition from inside VMDK. On the sample there is an EXT partition detected from inside "Ubuntu 64-bit.vmdk". Double click on it and open it in Reader mode.

If you see all the files from VM intact and proper file size, there is a decent chance that VMDK file has maintained its integrity. At this case it’s recommended to open it in Reader mode, as ESX/ESXi server would read it just same way. Besides Reader mode is the fastest of them all and will instantly display you contents of VMDK file.

Should you need to recover data that was deleted inside VMDK try Uneraser mode.

Use Full Recovery with pre-selected file system setting if you need to read data from severely damaged VMDK files or if Uneraser failed to locate lost data inside VMDK. Selected file system should correspond to the file system used inside VMDK. You shouldn’t select VMFS unless you had a ESX\ESXi Server running inside VM, nor EXT file system for Windows VM. If file system was changed because of format command, you need to select original file system that contained your data.

Now you can browse and check with built in preview integrity of recovered data. VMFS Recovery supports more than 150 different file formats including but not limited documents, databases, CAD\CAM blueprints, 3d models, numerous audio, video and picture formats. Also we guarantee that recovered data will be saved just like you see it. i.e. if you don't see a picture or data where it should be, purchasing VMFS Recovery will not improve this fact.

Important notice for RAID disk preview

You should preview files that are larger than: stripe size * disk count. For example if you have a 4 disks RAID 5 with 256Kb stripe size, you should preview files at least 1Mb. This will ensure that all parts of RAID are reconstructed properly and in correct order. For majority of cases files over 10Mb are more than enough to check RAID integrity.

RAID 1

RAID 1 is not actually RAID disk, as it don't have any stripe. This type of RAID can be considered as two independent single drives and you can use any our product compatible with file system used on your RAID disk.

Now if you were able to see proper values inside your files, you can consider purchasing VMFS Recovery and start saving recovered VMDK. Should you have any questions, please do not hesitate to contact me.



Possible issues:



Wrong command

There is another command in the VMFS Recovery called “Mount to Disk Letter ”. It can be found at context menu when you right click on the disk. (SAVE Wizard?) It mounts a VMDK as a virtual disk to the Windows OS and makes it available for 3-rd party software within this instance of Windows. However, it’s full features are available for registered license of VMFS Recovery only and you won’t be able to use this command to preview recovered VMDK file before purchase. The only proper method is to use algorithm described above.

Unregistered version

If preview failed to display contents of the recovered file, you should see a HEX preview. HEX preview usually indicates that VMFS Recovery doesn’t support such file type, (for example it’s EXE or BIN file) or it's failed to recognize supported format. You may also see an empty preview if no data can be read at all. Please do not hesitate to send a screen to our support team so we can assist you to determine if recovery was successful or not and advise you on recovery procedure.
