[SOLVED] External HDD not mounting due to missing uas module

Postby filipesaraiva » May 28th, '15, 01:15

Hello Mages, I am using Mageia Cauldron and recently I bought an external HDD (NTFS format). Sadly, Mageia is not automounting the HDD, besides I can see the HDD in dmesg:

[ 1253.942834] fuse init (API version 7.23)
[ 1434.365968] usb 1-1.2: USB disconnect, device number 6
[ 4540.155878] usb 1-1.2: new high-speed USB device number 7 using ehci-pci
[ 4540.303479] usb 1-1.2: New USB device found, idVendor=0bc2, idProduct=2322
[ 4540.303487] usb 1-1.2: New USB device strings: Mfr=2, Product=3, SerialNumber=1
[ 4540.303491] usb 1-1.2: Product: Expansion
[ 4540.303495] usb 1-1.2: Manufacturer: Seagate
[ 4540.303498] usb 1-1.2: SerialNumber: NA815V8S


fuse and ntfs-3g are installed, but I can not to see the HDD in Dolphin or in /dev/sdb. Anyone have some idea on what can I do?

Thanks!
PS.: It is working in Kubuntu 15.04

What do you mean by automounting? That is not configured by default, and configuration also depends on the desktop environment in use.
Based on the mentioning of dolphin, seems you're using KDE. So you do not get a popup for a new harddisk?

Please do the following after unplugging your disk - Open a terminal, and as root run:
Code: Select all
journalctl -af

then wait a few seconds, and plugin the disk, and wait again fifteen seconds or so, until no new output appears.
Then post everything here.

Thanks doktor5000. I am using KDE.

This is the output:

That recognition string is not complete. There also should have been some verbiage in the journal about a USB mass storage device being found, followed by the assignment of a /dev/sd* device.

If, in fact, this is all there was, then there is likely to be a defect in the USB controller on the external drive. You might also try changing the cable.

The HD is that Seagate device.

And a image from MCC hardware configuration:

That last line in right side says the module for the hardware is unknown.

As I said, Mageia is not auto-mounting the HD. In fact the HD is not recognized, because it there is not a /dev/sd* assignment - so I can not to perform a manual mounting too.

The HD works fine in the Kubuntu machine of my girlfriend, so it is not a problem of the HD itself or the cable. Maybe something in my hardware or software, I don't know.

[SOLVED] Re: External HDD (NTFS) not mounting in Mageia Caul

Postby filipesaraiva » May 28th, '15, 16:20

Hi sorcerers, after some investigation I found the uas module was not loaded by the kernel. It is the correct module for my HD, because it is an USB 3.0 using USB Attached SCSI protocol.

Looks like the uas module is broken for some devices on Linux (it is blacklisted in /etc/modprobe.d/blacklist_ide.conf), but it is working for my HD.

So, after run:

Code: Select all
# modprobe uas


My HD was recognized correctly. Now I will remove it from blacklist for now.

Thanks!

It would probably be helpful for others if you open a bugreport against cauldron for this, so that harddrake will know that similar drives require this module to be loaded or that upstream needs to add this to the respective udev rules to load this on demand, from which all distributions would benefit.
