If you have not already done so, copy ALL documents, pictures, movies and anything else not easily replaced to an external backup drive. It is a good idea to do this several times a week anyways and make sure to check to make sure that the files you copied over are good by opening several different ones each time.

You did not say which drive letter was mentioned or what version of Windows you are using but if it is the "C" or boot drive I would also make sure that you are making a boot disk (DVD) and a restore point daily just in case. New versions of Windows have different boot and restore abilities than older (XP) versions.
