What operating system are you using? Most likely, you are using some flavor of Windows and you can probably see all partitions now via you Disk Manager (in Control Panel, under Administrative Tools). If not and the partitiion is recognized by Windows, you can access there.
Now, once you recognize a partition, you simply use your file manager/explorer to see what is what.
Be careful that you don't delete Windows system files in the process. Good luck!!!
