[SOLVED] External HDD being listed by lsusb but not by fdisk

taufique · 2018-09-01 20:26:54

I am trying to mount a Western Digital My Passport Ultra 1TB external HDD to my laptop, The device shows up in `dmesg` and `lsusb` but can't find it with `fdisk -l`. But I can use the HDD from Windows 7 OS. So I am assuming there is not problem with HDD.

`uname -r` output:

4.17.11-arch1

Relevant `dmesg` output:

[115337.888331] usb 3-1: new high-speed USB device number 13 using xhci_hcd

I found a related issue in this thread where it is marked solved saying the following -

Atronach wrote:

the problem lies in the slow initialization of the drive's firmware to be ready to be scanned by the usb_storage kernel module

There were some ways pointed out in that thread to increase the `delay_use` parameter of `usb_storage` module but I couldn't try that because modprobe says `usb_storage` module is not found.

Any help?

Why is your kernel so old?

Why is your kernel so old?

Using the laptop after a while. Didn't do `pacman -Syyu` yet.

Always update before opening a support thread. Arch is a rolling release.

loqs · 2018-09-01 20:38:58

Well the current kernel contains

usr/lib/modules/4.18.5-arch1-1-ARCH/kernel/drivers/usb/storage/usb-storage.ko.xz

And you won't unless you can explain why you put the second "y" there… I don't know who advertises this shit, but "-yy" is for a very specific purpose and usually wrong.
The module is btw. "usb-storage".

Edit: blast.

@seth I thought modprobe performed automatic conversion on _

seth · 2018-09-01 21:00:21

With an intact database, yes - i overread the "modprobe" thing. (And eg. insmod resolves nothing)
The setup then sounds increasingly like a difference between booted and installed kernel.

Yep.

Did the update. Now `fdisk -l` is listing the HDD. Sorry for not trying an update before posting. I thought update wouldn't be any different in this case. So it didn't come to my mind.

No problem. The sooner you get in the habit of obsessively updating every hour on the hour, the happier you will be
