Fusion 8.5.10: unable to start virtual machine - vmdk corrupted

[mromini1]

Hi all, I have a big problem with a virtual machine. It does not start anymore and inside the log file I read this error:

I tried to fix the error with vmware-vdiskmanager -R without success.

Does anyone have any ideas? I enclose the complete log to the discussion.

Nobody has any ideas?

The best approach is to copy the vmdk to a Windowshost and read it with V2Vconverter from Starwind.
Second best is to use an older vmware-vdiskmanager - all current versions are broken.
Third best - but probably the easiest variant is to edit the size of the VMDK - apparantly the vmdk is 120 * 512 = 61440 bytes too small.
So please read VMDK-Handbook-Basics ,
extract the embedded descriptor
and edit the line that starts with
RW <value in sectors> SPARSE "Disco virtuale.vmdk"
Add 120 to  <value in sectors> and reinject the descriptorfile.
Make sure to keep a backup of the original descriptor !
I dont know if this will work - but it is worth a try.

Thanks for the instructions. I tried the third way without success. I still recovered the data I needed using 7zip to open the file and then I reinstalled windows from the beginning.
