Re: mount usb flash disk as read wrtie

 

Hi Paul,

In a recently installed ToriOS system, I tested with a USB pendrive with an MSDOS partition table and three partition made with gparted:

All three partitions were automounted rw both when the pendrive was plugged in at boot and when it was plugged in when ToriOS was running.

See the attached file.

Maybe it is an issue with flags. Run

sudo parted -ls

to print the flags (I may have other flags.)

Or maybe we are running different versions of ToriOS. Please tell me exactly which ToriOS version you have installed, and how it was or was not updated & upgraded.

Best regards
Nio

What file system is (NTFS or FAT32)?

You find that via

sudo lsblk -f

or simply

sudo lsblk -o name,fstype

The same device mounts fine on other computers running Linux

the device is

sdb 8:16 1 3.8G 0 disk
  sdb1 8:17 1 3.8G 0 part /media/torios/E6D3-22CA

I am at present unable to ssh in to run this remotely which would make
it easier to copy / paste information, so manually typed that.

Hi

Fresh install (iso downloaded 17/3/2017)

Plugged in usb flash disk, and I can't write to it,   are these devices
mounted read only.

Rignt now this is the ON;Y way I can get files from the toriOS netbook
to my desktop for inclusion in the manual.

When I plug this device in I get the error

The specified directory /media/torios/E6D8-22CA is not valid

While I probably know how to fix this, it is not the point when I am
writing the manual as I need to describe how the system behaves and
provide fixes in the manual perhaps.

Thanks for any help.

Hi Paul,

The problem might depend on the partition table and file system(s) on
the USB flash drive.

Please tell me, and I can create a similar system and test how it
behaves. You can reply with the output of the following commands

df
sudo lsblk -f
