Hey everyone,
Just a few months ago I started a new job and was told about installing removable hardrives. What you can do is get a special removable hardrive case that goes into your computer. Then there is a little drawer that you put your hardrive out of your computer and then turn it on. The computer will then boot off the hardrive and you can have as many hardrives and all with different operating systems.
You can also keep the HD that is in your comp now and put the removable HD in and then it would be like a really big ZIP disk.
Another bennifit is that when a bigger and better HD comes out you can put that on your computer.
