Good idea. Get a 400 GB drive, replace the 300 GB drive with it and
let the system rebuild the RAID. Keep the 300 GB disk safe - it will
prove invaluable if things go wrong.

Then, get a tool called Partition Magic. It is not very expensive - I
got it almost for free in a set with Norton Antivirus and Ghost. It
should indicate that you have one 160 GB partition and 240 GB of free
space. Either resize the partition or create a new one in the free
space (the safer option).

And you can add another drive to your system if you have a free PCI
slot and are willing to spend about $30 for a SATA controller.
