If I want to mitigate the risk of data recovery from a disk drive resold as surplus equipment, how would the use of virtual disks assist?
For example, if I have half a dozen vmdks on a 1TB drive (for sake of argument, presume they've been added to different VMs), and I decide to decommission the drive, would simply erasing the vmdks and then selling / repurposing the drive ensure that the underlying data had been well-erased - even without extensive overwriting (for example, a quick format back to a blank drive)?
