Ian and I have been fielding a number of queries regarding the free HD space on your computers.
The reason we have asked for you to come with 200GB of free space is because of the assembly exercise.
We are in the process of building the VirtualBox (VM) for the course and listed the space requirement as a worst case scenario.
If you are currently shy of space, clean up as best you can to get to as close to 200GB as possible. Move all of the items you are able to onto an external drive before coming to UMD (and put them back when you get home).
To answer the logical next question:
No we can not run the course on an external you bring, it is too slow and will fail.
If there are still issues during the course with regards to your disk space when we get to the assembly exercise, we can wipe and reinstall the VM (this takes about 30 min) to reclaim HD space. As the week progresses your VM will increase in size do to the computing we will perform.
If you still have concerns, let us know. We will send out a detailed course schedule and other info as we get closer in.
Looking forward to meeting you all.
Nic & Ian
