Unable to mount seagate 1Tb usb expansion drive


Hi folks, I plugged in a seagate expansion drive 1Tb into my linux server for backup purposes but it is unable to mount it. I can see the expansion drive in My computer but when I click on it, it says unable to mount, device already mounted or busy.
Windows can read the hard disk with no problems. It is ntfs formatted. I installed ntfs kernel and fuse. Ntfs is displayed when I run cat /proc/filesystems. However it just can't mount the expansion drive. Thanks in advance for your help.

Try running dmesg as root, then searching the output for a reference to that drive and posting the relevant lines here.

it looks like its being given the address of /dev/sdg1 but the newer logs state:

1. after you plug in the hard drive, check dmesg and scroll to the bottom to find the device address allocated to your drive.
2. issue a "mount" command to check where /dev/sd_1 is mounted in which directory (the address you got from reading dmesg). Usually in /media or /mnt.
3. now go to that directory.

Thanx.

I recently added a 2TB drive to my Debian machine. It wasn't sold under the Seagate name, but for all I know it might have been OEMed by them.

I had trouble seeing it also. I RTFMed and found out it came formatted NTFS (Debian is aggressively FOSS), so I partitioned and reformatted it ext3 using gparted.

I told the story at Geekazine, where I blog from time to time.

You might consider taking a look at in GParted. That might tell you something.

looks like your 1tb hd is being detected but not automatically mounted after plugging in. You will have to mount it manually using something like the following command depending on the /dev/sd_1 address you find in 'fdisk -l':
Code:
mount -t ntfs-3g /dev/sdh1 /mnt
You will then be able to access the contents from /mnt

Now; if that works it means that your autofs service is not working correctly or is not running.
