When PC is booting I see next message:



the disk drive for /media/sdb1 is not ready or not presented

Continue to wait or Press S to skip mounting or M for manual recovery


I'm newly at ubuntu and don't know well about how it works with eternal usb drives. (sdb1 is this one).



Here is content of sudo fdisk -l:

And here content of /etc/fstab:



# /etc/fstab: static file system information.

# Use 'blkid' to print the universally unique identifier for a

- Why this exactly happen?

- How to solve this trouble?

I don't know why you have /dev/sdb1 in your fstab, but I know why you see that error at boot:



While booting, the kernel does a mount -a which looks at the fstab and tries to mount all the filesystems, but apparently your drive isn't present at the moment of mounting or you are using an incorrect module.



So to prevent this, you could either:




  1. Delete/comment the line:



     #/dev/sdb1    /media/sdb1    vfat    uid=1000    0    0

  2. Add noauto as mount option:



    /dev/sdb1    /media/sdb1    vfat    uid=1000,noauto    0    0

  3. Change the entry for a label or UUID:



    UUID=AA64B45A64B42AC9    /media/sdb1    vfat    uid=1000    0    0

  4. Use auto instead ofvfat:



    /dev/sdb1    /media/sdb1    auto    uid=1000    0    0



You should make user that the /media/sdb1 directory exists. Notice that for each line I changed the uid to the UID of the username. You should verify your own using:





cat /etc/passwd | grep braiam

braiam:x:1000:1000:braiam,,,:/home/braiam:/bin/bash


My uid is 1000.



I would love to ask why so many entries in fstab, but will keep my curiosity for myself.
