Like title.
The HDD is working fine on Windows and other ditros and lsusb recognize it.

P. S.: why in Fedora everything is automounted goes into /run/media/<user name>/?

Do you want it automounted when it is inserted or automounted on startup? I have not done the former but I believe that you should look to udev rules for that. For the latter you can set auto in fstab and mount it via ntfs-3g. The issue, however, may be timing. I have a usb external disk and it is recognized on startup but the udev rules don't run in time because the device node is created before udev starts. Thus it shows up as /dev/sdb not the /usbdrives/ command.

With respect to your fedora question, while this is a Gentoo board and that is typically out of scope I believe that it is simply a convention. Different distros have different conventions for mounted media. The generall *nix default is under /mnt/ but I know that Redhat and Ubuntu prefer something else. It is no more than that and could likely be changed if you modified the right configuration files.

Yes, I need automounting on insertion. However, ntfs-3g is installed

What does your fstab have in it?

This is a line from my fstab that deals with a microSDHC NTFS filessystem

Code: Select all

/dev/disk/by-label/MSDHC	/mnt/msdhc	auto            noauto,user,exec,nodev,nosuid	0 0

I don't want it automounted at boot up, so I use noauto.

As CrankyPenguin believes, I do also that you would need a udev rule to automount upon insertion.

Good Luck

Note: I had to build fuse into ntfs-3g to get non-root mounting working. You may or may not need to do that.

Any hint or infos/docs about udev rules?

There is info out there, I did a google search with these keywords "udev automount usb devices"

This was one of many returned.

The link posted by Anon-E-Moose (nice pic by the way!) seems to be a good one for the rules. It is out of date in one respect. In Gentoo the udevinfo command no longer gets built. On more recent systems you now need to use the command udevadm as shown below:

Code: Select all

udevadm info -a -p $(udevadm info -q path -n /dev/sda)

This site: https://wiki.archlinux.org/index.php/Ud ... s_wrappers has a nice discussion of UDisks and other tools that can be used to trigger automount when a given disk shows up.

As you can see, KDE recognize only partitions on my internal GPT HDD (/dev/sda)
http://imageshack.us/photo/my-images/198/kdedisks.png/

Also, the system doesn't recognize the partition scheme of the external HDD

Code: Select all

ntfs-3g /dev/sdb /media/1tb/
NTFS signature is missing.
Failed to mount '/dev/sdb': Argomento non valido
The device '/dev/sdb' 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?

Ehm... So...

First of all I want to ask pardon: I don't know what exactly fixed the problem, but these are the changes I made into the kernel:

MSDOS_PARTITION [=y]
USB_STORAGE [=m]
MSDOS_FS [=m]
VFAT_FS [=m]
NTFS_FS [=m]

I didn't touch udev rules at all, neither my fstab!
Thank CrankyPenguin and Anon-E-moose for you time and support!
