plinydogg said: igknighted: thanks for your input. As I mentioned in the post in the VirtualBox forums, however, I didn't see any option to set the size of the swap partition. But, if you and the other poster think that fragmentation is an issue, I won't mess with it (I thought fragmentation was only a Windows issue though...)..
If I could just figure out how to get terminal services working right in Ubuntu I could get rid of that Windows partition...maybe I'll look into that....
Linux does do a much better job avoiding fragmentation under normal circumstances, but when the drive is nearly full, even the best file systems will fragment. Most say fragmentation will get out of control after a drive has less than 5% free, but I don't like to push it and tend to go with 25% free. Hard drive space is so cheap now (1TB for less than $100USD), there's no reason to fill drives to capacity.
As for your swap partition, forget that you are making a "swap" partition. Choose custom partitioning, then create one partition in the virtual drive that is at least 2.1GB as ext3 (or file system of your choice) and use it as /, then create another partition in the rest of the space, and format it as swap.
