Best approach is to ONLY use the newer SSDs with 'SED' (see my answer above/below.) I don't think the tools themselves can do much, unless they are triggering SED functionality.

comment HP Stream 13-C004TU Notebook for Ubuntu Install
I tried installing Ubuntu 14.04 LTS 64-bit on an HP Stream 11 (which is probably same as Stream 13). No joy in legacy mode, and UEFI (secure) mode no better. I don't think Ubuntu install likes eMMC storage, and second (and further) attempts to use <Esc> to get to BIOS settings failed over to OS 8.1 Install mode (and 2-3 hours spent cycling through 'reset' modes) instead. DEFINITLY AVOID Notebook is extremely slow to do anything, which must eMMC (as Intel Celeron N2840 should be fine). I'm taking it back.

Note: Ubuntu installation is fairly easy. Partially dismantling the Notebook, to install 2.5" HDD, is going to be the fun part. I can do it under 25 minutes, after 2-3 previous attempts.

I recommend (and use myself) the Orico USB 3.0 single-bay device: ebay.com.au orico 6619us3 You may need to disable UEFI (and enable legacy boot), to use this install method.

The hard part is creating a viable USB-installer. The most effective method is ask-a-friend, and have them create it on an existing Ubuntu 14.04 PC. You don't need to muck with boot order. Just use <F9>, to choose the device to boot from.

comment HP Stream 13-C004TU Notebook for Ubuntu Install
You need a computer, and/or external drive bay. It gets complicated, with UEFI, etc. What's your budget/pain-threshold for technical effort? Do you just want me (or someone) to send you the Notebook, already setup? ebay.com.au Ubuntu 15.6 Notebook

comment Has xorg deleted the nvidia 343 package?
It has been removed, but that still leaves 340 and 346. Check output from: sudo apt-cache search "NVIDIA binary driver"

comment Why doesn't running “sudo shutdown now” shutdown?
Or, combine shutdown 'now' with 'poweroff': sudo shutdown -P now

Any ATA erase functions are geared towards magnetic storage, and repeatedly erasing SSD (solid state) data does NOT actually remove any data previously stored. Instead in simply reduces the life of the device. You need to use tools/features specifically designed for SSD security.
