That depends, but I dont think so. FDisk is a program that manages partitions on your hard drive. You can learn about Fdisk at http://www.onecomputerguy.com/install/fdisk.htm
. Fdisk is a very useful program. I recommend you read up on it before actually writing anything in stone and using this program, because if you mess with partitions too much, your hard drive can get pretty messed up. But Fdisk is a pretty great tool to mess around with. I recommend you learn how to delete the partition that's being weird and then just create another one.
