Usb is stuck in readonly unless root and mostly terminal

[Snowarch]

I had an iso for ubuntu install cd on the flashdrive, so i wiped it using terminal program fdisk. it worked flawlessly once, however this time it wiped, but 2 issues. my file manager says its read only when drag and dropping, but i can format it as many times as needed. Even tho i need my root password to make the iso file go back on with startup disk creator. 

 

the root pass to mske an iso wouldnt be too bad, however i have only one usb, so i need to do this

 

1. wipe usb/flashdrive

2. put bios file on flashdrive

3. install that on other pc then wipe again

put install iso on and hope it actually starts starts the installer this time

 

can't copy paste paste via terminal, will say "access denied" and when i try to change the properties to can read and write for all groups, it puts back to read only. so my question is, how do i make the flashdrive writable in a way it'll work normally? and if there is a way to make it normal, how would i make it fat32? bios updating guide for asrock says fat32, but linux formats it to fat/msdos. will this work if so forget the second part of the question.

It sounds like the partition has a read-only flag set. You don't have anything on it, so your best bet is to rewrite the MBR and start fresh. Are you running Windows or Linux?

 

If Windows, then open an Admin command prompt and do this (let me know if something doesn't look right, going from memory here).

Be careful, you can wipe your system drive if you make a mistake.

DISKPART

LIST DISK

(look for the USB device, size is the key)

SELECT DISK 1 (or whatever number the USB drive is)

CLEAN

CREATE PART PRIM

LIST PART

SELECT PART 1 (make sure the size looks correct for your USB)

FORMAT FS=EXFAT QUICK

EXIT

EXIT

 

Should be good.

You should be able to do the same thing with fisk and mkfs commands, but I have only used that a few times myself and would need a reference guide. 

 

Checkout this page: https://www.tecmint.com/fdisk-commands-to-manage-linux-disk-partitions/

 

Probably also possible to list all the file-system and partition flags and clear the read-only bit, but again, something I have done maybe once in Linux and that was years ago.

strange, mkfs also made it msdos instead of fat32, and Will any of this make it writeable for non root? i can format with gui for some reason but still read only for gui, root/sudo su writable.

So I've had a look at the above post and it seems to be missing the specific command.

When doing the file system, you need to do "mkfs.fat -F 32 /dev/partition" according to the arch wiki (https://wiki.archlinux.org/index.php/FAT) to get a fat32 file system.

okay thanks. will try that.

well, I have a windows7 vm, but can't see the usb ports so... Not sure.
