HD C Fat32 and new D F NTFS .

Recently added a new hd (f) it is in NTFS and is the slave drive. The original C drive is Fat32.
My question is Can I do this or does both drives have to be the same. I cannot connect to the internet. Error mess. reads cannot find home page.
I went into the dos and did the ipconfig and came up with an error mess. #65. If anyone knows what is going on Please help. Thank you info@armacelarmorcorp.com
