I have burned a live-usb key of EOS with the dd method.
This worked fine. Then I needed to use it as a regular key. So I recreated an ms-dos partition table, created a fat 32 file system on it. Everything seems to be fine in gparted, but when I use it, the key seems to stay read-only, and a bootable key writer on mint tells me that there is no more space on it.
I reformatted the whole key with dd cat /dev/null > of=dev/sdb and started again to create a FAT32 filesystem on it but I still have the same problem.
ok, dd + recreation of partition table plus fat32 file system seems to solve my problem (after a reboot).
yet , i’m trying to make an btrfs file-system usb-key to make subvolume backup on it using btrfs send… But although the key is mounted with rw im unable to write ont it ???
Question do I have to create a subvolume on it to be able to write something to it ?
the device is mounted under /run/media/falke/xxxx with rw ?? Strange
/dev/sdb1 on /run/media/falke/9d80d7f8-dfdc-4d25-a6c0-18ef6b0431fa type btrfs (rw,nosuid,nodev,relatime,space_cache=v2,subvolid=5,subvol=/,uhelper=udisks2)
Yes i must run the commands as root (though not understanding why the backups have to be made with ro rights…), but in général I don’t understand why the media isn’t writable for a normal user…
