How to mount a flashdisk

[andredahl]

I do have sandisk16gb which do not come up ine the file manager system and do not get the usual sign up in the meny for removing it. It seems like the disk is not mounted at all. How can I mount it ?

Too many unknowns
Anything else you don't want to tell us?

Hmm I am using the RPI4 usb. Disk is FAT 32, am I still missing something ?

[andredahl]

Found a solution using win 10, Gparted and "raspberrytips.com/format-mount-usb drive/"

sudo mount /dev/sdb1 /media/usb -o umask=000

Then I do get the drive on the desktop. However if I reboot the drive disapair and it will not mount automaticly when I add the drive when RPI is running.

Gparted finds it mounted as dev/sdb1. Even though I can use the drive, fdisk -l can not find dev/sdb1 and returns not accessible on dev/sdb.


Any solutions ?

Since I could not get further information regarding making the pI4 to automaticly find the flashdisk, I put up a similar topic on the troubleshooting fora. That topic was deleted by the administrator, who did not know the answer and was not able to read what was written!

This is the additional information regarding the problem which I had added:

Sandisk USB flashdisk does not come up automaticly in the RPI 4.

fdisk -l
fdisk: cannot open /dev/ram0: No access
fdisk: cannot open /dev/ram1: No access
fdisk: cannot open /dev/ram2: No access
fdisk: cannot open /dev/ram3: No access
fdisk: cannot open /dev/ram4: No access
fdisk: cannot open /dev/ram5: No access
fdisk: cannot open /dev/ram6: No access
fdisk: cannot open /dev/ram7: No access
fdisk: cannot open /dev/ram8: No access
fdisk: cannot open /dev/ram9: No access
fdisk: cannot open /dev/ram10: No access
fdisk: cannot open /dev/ram11: No access
fdisk: cannot open /dev/ram12: No access
fdisk: cannot open /dev/ram13: No access
fdisk: cannot open /dev/ram14: No access
fdisk: cannot open /dev/ram15: No access
fdisk: cannot open /dev/mmcblk0: No access
fdisk: cannot open /dev/sda: No access

However gparted will show it as /dev/sd1 ?

To overcome this problem, what should my next step be ?

Found a solution and a conclusion.

The conclusion is that the updates of raspbian in may/june did not work properly, or the software had some bugs.

After installing the raspberry PI OS everything works very well.
