USB驱动器挂载异常问题求助

Hi Kamil, sorry to hear you're stuck with this annoying USB drive mounting issue—let's work through this step by step to get it fixed!

First, let's make sure I've got your problem right:

• Clicking the USB-HDD icon throws an error (even though I can't see the screenshot, the fact that manual terminal mounting works tells me the drive itself is functional)
• Manual mounting works fine, but the device name keeps switching between sda1, sdb1, etc., which is a hassle
• This only started happening in the last week, so it's likely a configuration glitch or minor system/device issue, not a total drive failure

Here are the most practical fixes to try, ordered by how likely they are to solve your problem:

1. Switch to UUID-based mounting (the most reliable long-term fix) #

Device names like sda1 change based on the order devices are detected at boot, but every drive has a unique UUID that never changes. Using this will stop the name switching and fix automatic mounting:

• First, find your USB drive's UUID by running this command in the terminal:

  sudo blkid
  

  Look for the entry matching your USB drive (you can spot it by the TYPE field, like vfat or ext4, and the drive size). It'll look something like:

  /dev/sda1: UUID="1234-ABCD" TYPE="vfat" PARTUUID="abcdef12-01"
  

• Create a permanent mount point (you can use any path you prefer, this is just an example):

  sudo mkdir /mnt/my_usb_drive
  

• Open the fstab file (this controls automatic system mounts) with a text editor:

  sudo nano /etc/fstab
  

• Add this line at the bottom, replacing 1234-ABCD with your actual UUID and /mnt/my_usb_drive with your chosen mount point:

  UUID=1234-ABCD /mnt/my_usb_drive auto defaults,noatime 0 0
  

• Save and exit (in nano, press Ctrl+O, hit Enter, then Ctrl+X)
• Test if it works immediately without rebooting:

  sudo mount -a
  

  If no errors pop up, your drive should mount automatically every time you plug it in—no more random device names!

2. Check your desktop environment's auto-mount settings #

Sometimes the desktop's built-in auto-mount feature can glitch out:

• For GNOME: Go to Settings > Storage, find your USB drive, and make sure the "Automatically mount" toggle is turned on.
• For KDE: Open System Settings > Removable Devices, check that "Enable automatic mounting of removable media" is checked, and that your drive type is included in the allowed devices.
• You can also check if the background service handling mounts is running properly:

  systemctl status udisks2
  

  If it shows "inactive" or has errors, restart it with:

  sudo systemctl restart udisks2
  

3. Check for file system errors on the USB drive #

Since this started happening recently, there might be minor corruption in the drive's file system:

• First, unmount the drive if it's currently mounted:

  sudo umount /dev/sdX1
  

  (Replace sdX1 with your current device name, like sda1)
• Run a file system check. For ext4 drives:

  sudo e2fsck /dev/sdX1
  

  For FAT32/exFAT drives:

  sudo fsck.vfat /dev/sdX1
  

  Follow the prompts to fix any detected errors—this might resolve the auto-mount failure.

Give these steps a try, and let me know if any of them work, or if you run into new issues along the way!
