[solved] Usb stick read-only, ISO9660 issue

Apparently, it's linked to the type ISO9660:

# df -Th
Filesystem     Type      Size  Used Avail Use% Mounted on
dev            devtmpfs  3,9G     0  3,9G   0% /dev
run            tmpfs     3,9G  880K  3,9G   1% /run
/dev/sda2      ext4       30G   19G  8,8G  69% /
tmpfs          tmpfs     3,9G  283M  3,6G   8% /dev/shm
tmpfs          tmpfs     4,0M     0  4,0M   0% /sys/fs/cgroup
tmpfs          tmpfs     6,0G   29M  6,0G   1% /tmp
/dev/sda1      ext4       11G  6,2G  4,3G  60% /data
/dev/sda3      ext4       70G   53G   14G  80% /home
tmpfs          tmpfs     781M   11M  771M   2% /run/user/1000
/dev/sdb       iso9660   2,6G  2,6G     0 100% /mnt

Then

# umount /mnt 
# dosfsck /dev/sdb
fsck.fat 4.1 (2017-01-24)
Logical sector size is zero.
# mount -v /dev/sdb /mnt
mount: /mnt: WARNING: source write-protected, mounted read-only.
mount: /dev/sdb mounted on /mnt.

Any idea?

That's expected if you literally have an ISO file system on the stick, what's your question?

Burn another one, but no way to get rid of it... Would you have a link to the procedure?

Reformat the stick if you don't want to use it that way... Instead of asking about read only and the ISO file system none of which is surprising. What are you actually trying to use that stick for?

It's to install a CentOs7 on an old 32bit Pc. But I tried

sudo dd if=CentOs7.iso of=/dev/sdb bs=1M status=progress

and it doesn't work... What do I do wrong?

What doesn't? Can you not boot off of the stick you've created?

thomasbb · 2020-12-21 22:29:25

CentOs7 is not the Os that is on the stick, I can't crush down the old one with the new...

sudo dd if=CentOs7.iso of=/dev/sdb bs=1M status=progress
and it doesn't work... What do I do wrong?

What was the output of the command?
