Like many ex M$ Windows users, I still have the occasional need to use it to run programs on that will not run under OSX. For example, probably all of the programs I use for PLC programming simply will not run natively on the Mac. This leaves me with two options - carry round another laptop (sometimes happens), or use a virtual machine.
A job I did recently for a client required I install some additional windows based software, to program the obscure controller that they had. At the time I just had my Mac on me, so I powered up Vmware and started to install the code. Unfortunately the installation started to hang about half way though - the issue was a nearly full disc.
I keep my virtual disc size fairly lean - the work I do is quite storage intensive, requiring lots of space, so I tend not to waste space if I can avoid it. It's easy enough to resize the disc if necessary. So that is what I did. Fortunately I am usually prepared for these things as you never know what will happen when you are stuck working in the middle of nowhere,
A friend of mine, just emailed me to ask how to change the disc size, so I thought I might as well add it up here
