manufacturer as a fixed disk, and not as a removable disk. As a consequence,
they require removing the `live-media=removable` boot parameter, which [[is
dangerous|doc/first_steps/bug_reporting/tails_does_not_start#entirely]].

* SanDisk Cruzer Extreme USB 3.0 16GB and 32GB

SanDisk had begun the production of flash drives configured as fixed disk in
39
2012 to meet new requirements for Windows 8 Certification, and ended it in mid-2014. The flash drives that
40
41
comply with this certification will have the Windows 8 logo on their packaging.
If a flash drive does not have the Windows 8 logo on its packaging, then that

drive will function as a removable disk and should work with Tails.

These machines do not start on USB sticks created using Tails USB
Installer, due to a firmware limitation.
148
149

A workaround for some of these machines is to use the [[manual
150
installation process|doc/first_steps/installation/manual/linux]].
151

Note, however, that this technique does not allow you to set up
a persistent volume.

Chainloading Tails from GRUB
----------------------------

To workaround problems in booting Tails on laptops with UEFI support, it is
possible to chainload the syslinux on the ISO image from another boot loader
that is already working on the laptop, like GRUB. Be careful not to modify at
all the options of syslinux in the process.

The following commands, run from the GRUB shell, might be helpful:

    set root=(hd1)
    chainloader +1
    boot

If no [[cold boot attack|doc/advanced_topics/cold_boot_attacks]]

After using Tails Installer, the "emergency shutdown" doesn't work
------------------------------------------------------------------
208

209
Tails Installer messes a bit too much with the USB devices for the
210
211
212
"emergency shutdown on media removal" feature to continue working after using
it. If you believe this feature is critical for the session you're running, we
advice you to reboot Tails.

Tails DVD eject failure

the DVD anymore.

Stream isolation inconsistency in Claws Mail
--------------------------------------------

Claws Mail isn't using its dedicated Tor SocksPort for Tor hidden
service IMAP/POP/SMTP servers (instead Tor's TransPort is used). This
is just a deviation from Tails' design and should have no adverse real
world consequences.

Tails fails to completely shutdown or restart

complete: the display gets scrambled, but the computer doesn't
completely shutdown or restart. Sometimes the caps-lock button light of
the keyboard flashes.

Hard to exchange files with the I2P Browser

283
It is impossible to exchange files between the I2P Browser and the amnesia user.
Tails developers's avatar
Tails developers committed
284
See [[!tails_ticket 8280]]. But you can do that with

administration rights from the command line. The home directory of the I2P Browser is

290
291
292
293
294
295
located in `/var/lib/i2p-browser/chroot/home/i2pbrowser/`.

You might have to check the permissions of the files that you want to exchange
with the I2P Browser:

  - They need to belong to the `i2pbrowser` user to be accessible from inside
    of the I2P browser.
  - They need to belong to the `amnesia` user to be accessible from outside of
    the I2P Browser.
