Found that by accident ....
Got a vsphere 5 VMDK of a VM I needed access to
A bit tricky unless you got a vSphere server somewhere (or vm player / vmware workstation)
The “vSphere 5.0 Virtual Disk Development Kit” let’s you mount VMDKs in Windows
Works a treat – BUT – my VM is Linux so I looked for a way to read EXT3 partitions on Windows ...
One tool I found :
Access to Ext 2/3/4, HFS and ReiserFS from Windows
It couldn’t read the mounted partition still, but by accident I saw you can mount VM images in general with that tool
Which works a treat – even with Linux VMDKs
Nice emergency tool – saving files onto local disk works a treat too ...
