okay, so i got a USB drive, and got it formatted as ext4... for linux use...
its practically useless. Permissions.
i thought when i was logged in as "root", i was like a GOD... you know, I can do whatever i WANT to... the system even displays the cool warning disclaimer "caution... you are ROOT, you could damage something"...
root is a nice CONCEPT? But it doesnt hold a candle to these permissions, lol... i managed to get a few things onto the USB i wanted to, by flitting around between several live LIN versions... the change permissions menus are blocked out for me too...
how in the &^%$ can i possibly not "be the owner of" my own USB drive, lol...
===========================================================
what menu option lets me do whatever i WANT to... i thought root gave me that...

(i honestly didnt understand your answer)
uhm... I'm ALREADY root...
since i am ROOT, why "cant" i change permissions of my USB drive let me use my own USB drive?
i thought when i was logged in as root, i was able to do anything. I cant even copy and paste files on my own USB drive, lol...

Sometimes had that problem myself. Could not do anything with a file on the usb drive, until one day used a file manager, which seemed to do the trick. But that was only one file. Only other thing I can think of is that you do not have write permission, a problem which I recently met. Then as root open terminal and do the following:
- Stick in the usb
- Gets device name. In my case /dev/sdb1
Code: Select all
umount /dev/sdb1 # If error message comes up, ignore and continue.
mkdir usb
mount /dev/sdb1 usb
(using your usb device name)- Check permission of USB like so:
Code: Select all
guest@porteus:~$ ls -ld usb
drwxr-xr-x 17 root root 16384 Jan 1 1970 usb/
beginning with 'drwx' - Change permission for all files:
Permission now changed to write, so should be able to write to all files on usb. 8)
Should at least eliminate any read permission problem. Re-insert usb and check.

@sedstar:
You got root from guest mode in command line. You booted root directly with the login cheatcode login=root. What do you mean you are root?

okay...
when i boot (graphic or RAM) i am login=root...
i thought that made me "root" and i "owned" everyhing everywhere... just not my USB, i guess, lol.
=======================================
on other distros?
i see examples people saying to go to terminal... and launch file manager with sudo or gksudo... making a file manager window with "all access".
i did this in Zorin with some success, although i see some error messages even though it worked...
============================================
if anyone wonder what i am doing? i am trying to do "easy2boot" multiple distro's on one big USB thumb drive...
I can easily accomplish it in WINdoze... but only with NTFS or FAT32... i am trying to do it in linux, with USB formatted for ext4 or now ext2... my main impediment is permissions, on both the zorin-downloaded zip file, and the USB drive itself...
for what its worth? porteus is the only distro i have any need to use ext2 or ext4 for (easy save option).... everything else the other distros seem happy in fat or ntfs... I am just using this as an exercise to get more used to using LINUX in general.

"sudo thunar" from the terminal window seems to be working...
sorry for being a total newb, lol...
