In the current form nwipe does not sanitize solid-state drives (hereinafter referred to as SSDs)
of any form (SAS / SATA / NVMe) and / or form factor (2.5" / 3.5" / PCI) fully due to their nature:
SSDs, as the transistors contained in the memory modules are subject to wear, contain in most cases
additional memory modules installed as failover for broken sectors outside
of the host accessible space (frequently referred to as "overprovisioning") and for garbage collection.
Some manufacturers reserve access to these areas only to disk's own controller and firmware.

It is therefor always advised to use nwipe / ShredOS in conjunction with the manufacturer's or hardware vendor's own tools for sanitization to assure
full destruction of the information contained on the disk.
Given that most vendors and manufacturers do not provide open source tools, it is advised to validate the outcome by comparing the data on the disk before and after sanitization.
A list of the most common tools and instructions for SSD wipes can be found in the [SSD Guide](ssd-guide.md).

hdparm provides some of the information regarding disk size in sectors as related to the host protected area (HPA) and device configuration overlay (DCO). We do however have our own function that directly access the DCO to obtain the 'real max sectors' so reliance on hdparm may be removed at a future date.

Here's a script that will do just that! It will create a directory in your home folder called 'nwipe_master'. It installs all the libraries required to compile the software (build-essential) and all the libraries that nwipe requires (libparted etc). It downloads the latest master copy of nwipe from github. It then compiles the software and then runs the latest nwipe. It doesn't write over the version of nwipe that's installed in the repository (If you had nwipe already installed).

As it always downloads a fresh copy of the nwipe master from Github, you can always stay up to date. Just run it to get the latest version of nwipe. It only takes 11 seconds to compile on my i7.

If you already have nwipe installed from the repository, you need to take care which version you are running. If you typed `nwipe` from any directory it will always run the original repository copy of nwipe. To run the latest nwipe you have to explicitly tell it where the new copy is, e.g in the directory `~/nwipe_master/nwipe/src`. That's why you would run it by typing `sudo ~/nwipe_master/nwipe/src/nwipe` alternatively you could cd to the directory and run it like this:

easy bootable CD version. nwipe was created out of a need to run the DBAN
dwipe command outside of DBAN, in order to allow its use with any host
distribution, thus giving better hardware support. It is essentially the
