  • 1.  Get access to Host disks for recovery purposes

    Posted Mar 01, 2025 09:44 AM

    Hello, 

    I'm having a huge problem, since one of the VM was deleted on my Host VMware ESXi. I would like to use a Third party recovery tool (such as easyUS data recovery wizard).

    but the issue, i have inherited this configuration as a technical support, i don't have the old configuration, thus i don't know where the data where hosted. my best shot is to make all the disks available and scan all of them, in order to recover what i can recover.

    I'm looking for the best solution, to enable / show the disks of the host inside one vm, where i will be launching the recovery tool.

    any ideas how to perform this configuration? 

    or is there any other suggestion to recover the data from a lost mounted disk ?

    your help is highly appreciated!

    I suspect the only way you'll get the VM back is from a backup. I've never come across any tool that can recover a VMs files if they've been deleted using the 'Delete from Disk' option. The deletion is permanent.

    Thank you for your reply Trevor, 

    In fact we have an encrypted vmdk file which holds the VM that we need to recover it.

    Any idea if there is a way to recover it? even if it is encrypted?

    Thank you,

    Um, if you have an encrypted disk you'd need access to the encryption keys used to encrypt it, if you can't access this then the disk will be unrecoverable.

    If I'm understanding you correctly.

    unfortenatly, i don't have the encryption key. (due to an attack on it)

    I will try to see if we can read any blocks from it using a third party tool... do you think it feasible and recoverable?

    I think it may be your only choice. Although if the original disks had an encryption policy applied you still won't be able to access them.

    Hello Trevor, 

    Thank you for your advices, i don't think it used to have an encryption, I will keep you updated with the third party recovery tools.

    In fact, now i'm blocked with another issue!!

    I recently changed the password of my ESXi 6.7.0 VMware host using the web interface. I saved it in my password manager and copied and pasted it via TeamViewer from my personal Mac laptop to a Windows VM (where I accessed the VMware web interface).

    I used the new password throughout the weekend. At times, I had login issues, but after a short while, I was able to log in again.

    Today, however, I'm trying to connect, and it's not accepting the password-neither from the same laptop nor from other Windows PCs. It seems like special characters are causing problems. The password contains ^ ; ad {, and I suspect these characters might be the issue.

    I've noticed that many special characters create login issues. For example, when I try to log in to the VMware Linux OS, the @ symbol isn't being entered correctly, and ^ seems to cause issues as well.

    I believe my laptop copied and pasted the password in a format I can't replicate now.

    any ideas on how to resolve this?

    Thank you so much!
