There is a related thread on this topic that seems to have died out so I am starting a new one 
I experiencing extremely frequent .vmdk disk file issues when running VMWare Workstation 9 VMs from Storage Spaces under Windows 8 Pro (x64). The attached image is an example.
Storage Spaces is configured with one disk redundancy (3 x 3 TB storage pool with 1 disk redundancy, partitioned into 2 x 2.04 TB storage spaces). I have no issues when running VMs from non-storage space drives but almost always, after shutting down a VM on a storage space, I will get a .vmdk internal consistency warning on the next boot. I have configured VMWare Workstation to "Fit all virtual machine memory into reserved host RAM" with no change in behaviour. The issue persists with version 9.02.
I have not observed file corruption with any other applications that write to the storage spaces, including write intensive applications such as media ripping.
Corrupted vmdk files can generally be repaired with "vmware-vdiskmanager.exe -R".
Has anyone else come across this issue?
