ShredOS includes the latest Nwipe official release, but in addition includes other disc related utilities such as Smartmontools, hdparm, a hexeditor [hexedit](https://linux.die.net/man/1/hexedit), and, the program loadkeys which can be used for [setting the keyboard layout](https://github.com/PartialVolume/shredos.2020.02/blob/master/README.md#how-to-set-the-keyboard-map-using-the-loadkeys-command-see-here-for-persistent-change-between-reboots). Nwipe automatically starts it's GUI in the first virtual terminal (ALT-F1), hdparm, smartmontools and hexeditor can be run in the second virtual terminal, (ALT-F2). Nwipe will erase drives using a user selectable choice of seven methods. hdparm - amongst many of its options - can be used for wiping a drive by [issueing ATA erase commands to the drive's internal firmware](https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase). This is a planned feature addition to nwipe.
ShredOS boots very quickly and depending upon the host system can boot in as little as 2 seconds (typically 4 to 6 seconds) on modern hardware, while on an old Pentium4 may take 40+ seconds. Nwipe automatically starts in GUI mode and will list the disks present on the host system. In fact, Nwipe can launch so fast that the USB devices have not yet initialised so the first time nwipe appears it may not show any USB drives. If you then use Control-C to exit and restart nwipe, you should now see any attached USB devices. You can then select the methods by which you want to securely erase the disk/s. Nwipe is able to simultanuosly wipe multiple disks using a threaded software architecture. I have simultaneously wiped 28 loop devices in tests and know of instances where it's been used to wipe upwards of 10 drives on a system.

The vanilla version of ShredOS boots into nwipe's GUI and shows the available discs that can then be selected for wiping. It does not autonuke your discs at launch, however it is capable of doing that, if you edit the grub.cfg file and specify the appropriate nwipe command line option. Details of configuring nwipe's launch behaviour is shown below [How to run nwipe so you can specify nwipe command line options](https://github.com/PartialVolume/shredos.2020.02/blob/master/README.md#how-to-run-nwipe-so-you-can-specify-nwipe-command-line-options)
