Lock/Protect a partition.

[AND_YOU_ARE]

I have a 80gb hard drive I partitioned into two parts. One I am going to use to back up my system drive, and the other to transfer data around.

I would like to know if there is some way I can lock down the first partiton, protecting it from any other changes. Is there a program that will allow me to do this? Or is there some way to do it in windows? I would also like to use this as a usb boot device, so locking and unlocking should be able to be done easily and any where.

Thanks for any suggestions.
