Assuming that I am NOT going to add NTFS drivers that allow read+write of NTFS partitions, I was wondering if the choice of filesystem when I partition an external USB drive matters. The choices appear to be HFS+ vs. FAT32.
For the time being, I simply created two half-sized paritions, one of each type. :)
I plan to run various versions of Windows, and keep the VirtualBox files on the external drive.
UPDATE: to clarify-> I'm not concerned about letting my VirtualBox VMs mount this drive, I'm talking purely about using this drive as a place to stick my VirtualBox images, because my main drive is already pre-occupied.
Thanks for the suggestions. I'm going to migrate to HFS-only. An additional consideration was that a partition not mountable by normal PC's cannot be a vector for Conflicker. In this specific case, this external drive is technically a "lab" device, I might need to let other people use it. (This does not prevent infection of the guest OS, but it prevents the drive from being a host-to-host vector.) – benc – 2010-07-31T06:10:11.253
