Virtual Machine Unable to Reliably See Harddrive

[jetblackrx89]

When launching Disk Utility immediately after selecting the language for the installer, the hard drive will only appear properly about once out of every 20 or so boots.

Formatting the the drive as HFS doesn't help. Even post-install, when the VM reboots, there is a high chance the hard drive won't be detected on the next boot. I'm not sure if this is an issue with VirtualBox itself.

I have tried all types of hard disks and both dynamic and fixed sizes. There is so far no pattern in terms of when the hard drive decides to be detected.
