I'm trying to mount a windows XP disk onto linux. I have the drives pulled out of the old machine and plugged in to my USB port via a universal drive adapter kit. Just a few cables that plug into this SATA disk and provide power and connect to USB. When I plug in the drive via usb, a new device appears (/dev/sdc).
Code:

$ fdisk -l /dev/sdc

... returns nothing. And trying to mount it ...
Code:

$ sudo mount -t ntfs /dev/sdc /mnt/win
mount: wrong fs type, bad option, bad superblock on /dev/sdc,
       missing codepage or helper program, or other error
       (could this be the IDE device where you in fact use
       ide-scsi so that sr0 or sda or so is needed?)
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

When I plug the device in, this shows up in my dmesg log ...
Code:

 /dev/sdc: unrecognized partition table type
No partitions found

I've compiled NFTS file system as a module and see this ...
Code:

$ lsmod
Module                  Size  Used by
ntfs                   78730  0
nvidia               9603619  28

Anyone have any ideas here?

/dev/sdc is the name of the device. You should be trying to mount /dev/sdc1.

But I have no /dev/sdc1 device. Only /dev/sdc exists.

try emerging ntfs-3g and then mounting.

Also, you may need to compile ntfs support in kernel (I can't remember if ntfs-3g provides kernel based driver or something else).

mount -t ntfs-3g /dev/sdc1 /mnt/point

Why are you running fdisk as an unprivileged user? Unless you have udev configured to offer special permissions, you probably need root permission to access the device node. Please run, as root, the commands sfdisk -l /dev/sdc; file -s /dev/sdc; od -tx1z -Ax -N512 /dev/sdc.
