[Solved] Block devices not recognised

Hey guys,

I already used up all resources that came to my mind, so now I will ask you.

My system does not recognise any block devices as such. They are recognised as USB-devices, though.

Here is the output for lsblk:

[ma@argo ~]$ lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
nvme0n1     259:0    0   477G  0 disk 
├─nvme0n1p1 259:1    0   512M  0 part 
├─nvme0n1p2 259:2    0     4G  0 part [SWAP]
├─nvme0n1p3 259:3    0    30G  0 part /
└─nvme0n1p4 259:4    0 442,4G  0 part /home

Here is the output for lsusb:

[ma@argo ~]$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 0bda:0316 Realtek Semiconductor Corp. 
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 5986:2113 Acer, Inc 
Bus 001 Device 003: ID 8087:0a2b Intel Corp. 
Bus 001 Device 011: ID 1058:25a1 Western Digital Technologies, Inc. Elements / My Passport (WD20NMVW)
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The Western Digital drive (Device 11) is the one I am interested in.

When I check

 systemctl status systemd-udevd.service

it says

 Aug 23 19:50:08 argo mtp-probe[3345]: bus: 1, device: 11 was not an MTP device 

I already searched the internet for similar issues but the suggested solutions don't work for me.

[ma@argo ~]$ uname -r
5.2.9-arch1-1-ARCH
[ma@argo ~]$ pacman -Q linux
linux 5.2.9.arch1-1

I really hope you guys can help me.

Thanks

PS.: It's not only the WD-drive but also all the other  usb-drives I found. However, I can mount my android phone via simple-mtpfs.

Re: [Solved] Block devices not recognised

Can we get a quick summary of the solutions you googled that didn't work? I don't want to tread over the same ground.

Re: [Solved] Block devices not recognised

Well there are several threads in various forums with the same problem but they all solved the problem by rebooting (the problem was that people were not booted into the new kernel because of an update and there was a mismatch between the running kernel and the installed modules). This is also what the wiki suggests. Someone else found that their drive was simply broken. Mine is not, because it works on other computers.

This is pretty much it...

Re: [Solved] Block devices not recognised

The research I've done seems to suggest that you need to edit your udev rule for the device, like here: https://superuser.com/questions/1206664 … -mass-stor

But beyond that I defer to anyone with experience with these issues.

Re: [Solved] Block devices not recognised

Is this a new install? Are you using a DM?
It is possible that simple-mtpfs is interfering with udevd. I would try uninstalling it and see what happens.

I installed arch about 6 months ago. I did not have this problem up until a month ago or so. I don't even know when it started and whether it had a trigger, because I haven't used my drives for a while...

I deleted simple-mtpfs and rebooted, but still nothing...

Re: [Solved] Block devices not recognised

Ok, I really don't know what happened. Suddenly everything works again and I don't know why. 2 hours ago it did not work and I haven't done any other changes; no updates, no (de-)installations, no changes in any settings. It's very strange... I hope the problem won't come back.

Thanks guys...

Re: [Solved] Block devices not recognised

Hey, it's me again.

The problem is back and I still don't know why. As it seems, sometimes when I boot into my system it does recognise the usb-drives, and sometimes it does not (This happens more often).

I thought maybe it's a hardware problem so I booted from a bootable stick a couple of times and had no problems mounting external drives, so I assume that the hardware is ok.

Now I'm back here and hope that you can help me.

Here are the outputs that xerxes_ asked for:

Re: [Solved] Block devices not recognised

Android phones do typically not register as storage devices (unless maybe their SD card)

The WD thingy is registered as storage device but doesn't seem to respond.

a) is there a pattern depending on whether the device is attached before the boot ./. later on?
b) run "dmesg -w" and attach the device, post the output that it generates.
c) usb autosuspend? Do you use stuff like TLP, powertop etc?

Hi, I actually do have TLP. I disabled the usb-autosuspend option and now everything works stabily (I hope). I believe this was the issue. Thanks man!
