[SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

hi everyone, I'm new here. 
I just can't figure this out.

I have a USB flashdisk, but when I plug it into my computer, it doesn't show up in the file manager. 
However, it does appear when I run

lsblk

I also tried mounting it manually, and it works perfectly fine. 
So why isn't it automounting like the other USBs?

Here's the output of lsblk:

lsblk
NAME        MAJ:MIN RM   SIZE RO TYPE MOUNTPOINTS
sda           8:0    1   1.9T  0 disk 
`-sda1        8:1    1   1.9T  0 part /run/media/asakusa/flashdisk
nvme0n1     259:0    0 476.9G  0 disk 
|-nvme0n1p1 259:1    0     1G  0 part /boot
`-nvme0n1p2 259:2    0 475.9G  0 part /

The flashdisk seems to be mounted in the output, but that's only because I mounted it manually.

That's all, thanks guys!

Please use [code][/code] tags. Edit your post in this regard.

What "filemanager", where do you expect it to show up - and how?
Do you rely on the filemanager for automounts or is that provided by something else and the filemanager is a red herring?

but why it wasnt automatically mounted like any other usb

What filesystem is this?

lsblk -f

Sorry, my bad, I've edited the post.

I'm using GNOME Files as my file manager. Honestly, I'm not really sure whether it's the file manager that's handling the automounting or if it's done by another service.

How can I check what is actually responsible for automounting? I do remember installing gvfs on my system — could that be involved, or possibly conflict with the file manager?

Here's the output of lsblk -f:

NAME        FSTYPE FSVER LABEL UUID                                 FSAVAIL FSUSE% MOUNTPOINTS
sda                                                                                
`-sda1      vfat   FAT32       7EF5-13D2

Re: [SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

I'm using GNOME Files as my file manager.

So, nautilus?
Afaict you can enable or disable automounting in nautilus, for specific device handling, it would still respect your fstab, is the device listed there?

Either external drives are automounted?

Re: [SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

yeah that's it

it would still respect your fstab, is the device listed there?

no, i also tried to check another flashdisk that can automount, but when i check fstab with command

cat /etc/fstab

the device isn't listed either.

oh and the automount just doesn't work for this one flashdisk, and this problem started when i tried to change the flashdisk from a bootable flashdisk to a normal flashdisk. i did several steps to format the flashdisk like this:

i used gdisk for formatting my flashdisk
1. first i deleted all the partitions on the flashdisk 
2. secondly i created one partition that used all space on the flashdisk 
3. and after that i formatted the partition with: 

mkfs.fat

did i do something wrong?

Re: [SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

Do you get any errors from

udisksctl mount -b /dev/sda1

or do related errors show up in dmesg/the system journal?

no i didnt get any error either from dmesg or the udiskctl command, here's the output for udiskctl command

Mounted /dev/sda1 at /run/media/asakusa/7EF5-13D2

and here's output from dmesg after i plug in my flashdisk

Re: [SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

udisksctl info -b /dev/sda

Check HintAuto, it's likely "false"? (And this isn't actually FM specidfic)
=> https://wiki.archlinux.org/title/Udev#S … e,_are_not

Seems like a udev bug, misdetecting the nature of the device (unless you've added some local rule)

I actually know how to fix the flash drive — I could just format it using Rufus on my Windows machine, and it will magically be detected on my Arch system.
I just want to know the reason why, when I manually format the flash drive with gdisk, it doesn't get auto-mounted.

Re: [SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

Does it show up with "HintAuto=false"?
Post the entire udisksctl info and compare "fdisk -l /dev/sda; file/dev/sda1" for the drive in either condition.

Compare "fdisk -l /dev/sda; file /dev/sda1" for the drive in either condition.

And here's the output for both of my flash drives. sda1 is the one that doesn’t get auto-mounted:

The fdisk output is different. How can I make the manually formatted flash drive behave the same as the one that auto-mounts?

Re: [SOLVED]flashdisks didnt showed up in the file manager nautilius gnome

[@uote]Disk identifier: 0x00000000[@/uote]
But

fdisk -l /dev/sda

and

fdisk -l /dev/sdb

(sdb1 seems to hold a bogus partition table)

One thing is that you ddin't add a partition label, https://man.archlinux.org/man/fatlabel.8.en (though you can issue one w/ mkfs.vfat, https://man.archlinux.org/man/mkfs.fat.8.en#n ) - udisks will use the volume ID as mountpoint, but maybe nautilus is more picky.

And for posterity please record whether  it was indeed just down to the label.

oh yeah sure, and my problem was bcs i format the wrong partition instead of formatting /dev/sda1 i was formating /dev/sda, there's nothing wrong with the label it just causded by the wrong formatting step
