creating NTFS partition with fdisk

[LRT]

this is what i'm doing to format an NTFS partition with fdisk:

# fdisk /dev/sda
n (to create new partition)
p (for primary partition)
1 (for partition number)
default for First cylinder
t (change partition's system id)
1 (for partition number)
L (to view hex codes)
87 (for NTFS partition)
w (to write changes)

after this i mount the partition as follows:

mount -t ntfs /dev/sda1 /media/sda1

but i get this error:

NTFS signature is missing.
Failed to mount '/dev/sda1': Invalid argument
The device '/dev/sda1' doesn't have a valid NTFS.
Maybe you selected the wrong device? Or the whole disk instead of a
partition (e.g. /dev/hda, not /dev/hda1)? Or the other way around?

i'm not sure what i'm doing wrong. i'm sure i'm selecting the right device. do i have to create a NTFS file system??? i'm not sure how to do this.

im not sure how to do it with fdisk but you can do it with gparted. you just need to install ntfsprogs to be able to partition and formate ntfs with gparted.

sudo apt-get install ntfsprogs gparted

yes i know how to do it with gparted, but i want to know how to do it with fdisk.

You created a partition, but you haven't created a file system, in other words you have to format your ntfs partition. Make sure you have ntfsprogs installed then in a terminal type:

mkntfs /dev/hdx

where hdx is your hard drive or partition.

man fdisk

Try using 7 instead of 86 or 87. Those are for volume sets.

After you create the partition with fdisk you need to create the filesystem on the drive. Type "mkfs -t ntfs /dev/sda1" (changing sda1 to whatever are your drive letters). After that you need to enter the drive into the fstab by typing "fsck -f -y /dev/sda1" again replacing the letters.

I hope I could help.

Hi! You have to install the ntfs-3g package:

sudo aptitude install ntfs-3g

With this package installed you can create a NTFS Filesystem. The partition that you create with fdisk is not so important, you can create an NTFS filesystem on a FAT32 partition and it will have all the characteristics of NTFS (Windows will not recognize it btw)

To create the filesystem run

mkfs.ntfs /dev/sdb1

(instead of sdb1 put your partition address).

To know witch filesystem you have on a device the command is:

file -s /dev/sdb1

what is the difference between 86 and 87 ?

According to this site, 0x86 is for FAT volume sets and 0x87 is for NTFS or HPFS volume sets. I don't know if this is 100% accurate, though.
