In CrOS external media shows up under /media/removable/ so check there to make sure it's mounted.
On my system in the croutn chroot it didn't show up under /media/removable/ but it did show up under /var/host/, see below:

(bionic)dennyl@localhost:~$ ll /media/removable
lrwxrwxrwx. 1 root root 25 Aug 13 14:58 /media/removable -> /var/host/media/removable/
(bionic)dennyl@localhost:~$ 
(bionic)dennyl@localhost:~$ mount|grep sda
/dev/sda on /var/host/media/removable/Pop_OS 20.04 amd64 type iso9660 (ro,nosuid,nodev,noexec,relatime,utf8,uid=1000,gid=1000)
(bionic)dennyl@localhost:~$ 
(bionic)dennyl@localhost:~$ ll /var/host/media/removable/
total 2.0K
dr-xr-xr-x. 1 dennyl dennyl 2.0K Jul  2 16:58 'Pop_OS 20.04 amd64'/
(bionic)dennyl@localhost:~$

ok, so, i have seen this aswell..... any time i try to access it, no matter what, i always get 'permission denied'

Edit: sorry for late reply, but, I have been very busy all day

Edit 2: Sudo works, but how can i do this so i don't needa use sudo, i needa use git/jetbeans on the usb, and that will mess everything up with sudo

@Jonyk56,

Check out the ownership and permissions of the root directory in the external media with:

• ls -ld /var/host/media/dstorage
• or just if it works for you -
• ls -ld /media/removable/dstorage

You may have to change at least the ownership to 'jonyk5' with:

• sudo chown jonyk5:root /media/dstorage

You can use the '-R' option to chown to change the ownership on all subdirectories too.
If the permissions aren't set to executable in the directories you need then use chmod to change them too.

Also, if /media/removable/dstorage is mounted 'noexec' you may need to remount with exec permissions.

Hope this helps,

ok, also, one quick question, do i do the chown in crouton, or shell?

Edit: i figured it out, I'ma be adding a bit of a wiki post here to make it easier for folks like me =P
