Mounting a Windows created external disk on a Linux system (Centos 7, now) and seeing :


mount: unknown filesystem type 'ntfs'

Its time to install some more free software ! The disk looks like :

[root@server svenn]# fdisk -l /dev/sdbg

Disk /dev/sdbg: 3000.6 GB, 3000592977920 bytes, 732566645 sectors
Units = sectors of 1 * 4096 = 4096 bytes
Sector size (logical/physical): 4096 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disk label type: dos
Disk identifier: 0x49208b59

    Device Boot      Start         End      Blocks   Id  System
/dev/sdbg1            2048   732565503  2930253824    7  HPFS/NTFS/exFAT

NTFS, the mark of a windows user …  well on to solving it :

If you haven’t install the epel-repo do that first :

yum install epel-release

Then install this package :

yum install ntfs-3g

and mount this little disk :

mount /dev/sdbg1 /media/tmp_disk

optionally you could specify the type like :

mount -t ntfs /dev/sdbg1 /media/tmp_disk

my /var/log/messages looks like this :
