Problem Accessing disk

Basically I�m Absolutely New to Opensolaris (Started Using It This Morning),
I�m Following A Tutorial On How To Access NTFS Partitions.
Device Driver Utility Finds It And Says Everythings Fine With It
DISK : ST3160022ACE
Capacity : 160G
Driver : cmdk
Path : /dev/rdsk/c4d0s2

But When I Run fdisk /dev/rdsk/c4d0s2 It Says :
�fdisk: Cannot open device /dev/rdsk/c4d0s2.�

I Know This Will Be An Annoying Nooby Mistake But Please Help :wink:

why will you run "fdisk" on a disk with an ntfs filesystem?

Because I Wanted To Determine The Partition Is The NTFS Partition, Plus The Tutorial Said To Do It.

Heres The Link To It: Mounting Windows' NTFS on [Open]Solaris x86/x64 : Giri Mandalika's scratchpad

although im trying to mount a ide hardrive not usb

what gives:

ls -l /dev/rdsk/c4*

as an output?

Sorry if im coming accross as a chore

try "fdisk /dev/rdsk/c4d0p0"

also run "devfasadm -Cv" and "devfsadm -v" to clear unused device entries on your system.

Thanks!
That Worked, And It Allowed Me To Mount It
Your A Life Saver :wink:

Sorry For Being A Noob :o

Ok. It Won't Let Me Mount On OpenSolaris, This Is What It Says

ntfs_attr_pread_i: ntfs_pread failed: No such device or address
Failed to read NTFS $Bitmap: No such device or address
Either the device is missing or it's powered down, or you have
SoftRAID hardware and must use an activated, different device under
/dev/mapper/, (e.g. /dev/mapper/nvidia_eahaabcc1) to mount NTFS.
Please see the 'dmraid' documentation for help.

Can Someone Translate That Into Noob For Me :wink: Cos Google Doesnt Have Anything On It
