Open Windows Explorer, right click on the drive/partition in question> properties. That first property page will tell you what kind of File system is on the drive.
In the run box, type in 'command' or 'cmd' and hit enter, in the command window that opens, type in 'convert x: /fs:ntfs.' 'x' being the drive/partition you want to convert. To convert a drive from ntfs to fat32 you'll need third party software such as PowerQuest's Partition Magic.
There are some really good articles that you should should read before converting your drive(s):
Open Windows Explorer> Tools> Folder Options> 'View' tab> Scroll to the bottom of the list and untick 'Use simple File Sharing.' When that's applied, you can right click on just about any drive/folder/file> properties and and you'll have a new security tab. There's also some good articles around on using that stuff. Don't lock yourself out of program files now, he he.
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
