Cannot Mount NTFS USB External

Postby Hunkydunky » 2017/07/23 15:02:10

Hello,
I have literally exhausted all the forums discussion on this topic so hopefully someone can shed light on my issue.
I have a Seagate 2TB external USB drive I want to mount to my Centos 6 machine but it does not want to work.
I get this message when I attempt to mount:

mount -t ntfs-3g /dev/sdb1 /mnt/smb
NTFS signature is missing.
Failed to mount '/dev/sdb1': Invalid argument
The device '/dev/sdb1' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

These are the details of the drive:

parted /dev/sdb print
Model: Seagate Backup+ Desk (scsi)
Disk /dev/sdb: 2000GB
Sector size (logical/physical): 4096B/4096B
Partition Table: msdos

Number Start End Size Type File system Flags
1 8192B 2000GB 2000GB primary

fuse and ntfs-3g are installed...I'm at a loss.

Any ideas ?

You haven't shown that the partition is formatted as NTFS.

What does file -s /dev/sdb1 say?

Well you ran it against the partition but the output you get is totally different from what I get when run against my one and only NTFS partition.

Code: Select all

# file -s /dev/sda1
/dev/sda1: x86 boot sector, code offset 0x52, OEM-ID "NTFS    ", sectors/cluster 8, reserved sectors 0, Media descriptor 0xf8, heads 255, hidden sectors 64, dos < 4.0 BootSector (0x80)
