VMWare Workstation 9 and 4TB drive

Hi,

I recently tried to use a 4TB to backup and run my VM's from. However it keeps on corrupting the VM's. I have tried using MBR and GPT as well as partitioning the drive so that eacg partition is only 1TB. Still no luck. Hyper-V and Vbox handles te full disk in any format without a problem so it is not the disk.

Any ideas why this is happening?

Thanks

Nico
