 # reHDD

-## Useful for:
-* checking new drives for the first time
-* checking used drives for their next live
+## Features:
+* show S.M.A.R.T values of attached drives
+* checking used drives for their next live based on threshold limits
+* delete a drive instant with wipefs
 * deleting a drive securely via overwriting
+* only needs a display and keyboard
+* process multiple drives at once
+
+## Download USB Image ##
+[2.5GB image v1.0.0](https://schuttercloud.com/s/ggxGH9sA326aRfK)   (`wget` is your friend)
+
+Use [Etcher](https://www.balena.io/etcher/#download) or `dd` to create an bootable USB drive .

 ## Debian Build Notes

-* apt-get install ncurses-dev git make g++ 
-* clone repo
-* make release
+* `apt-get install ncurses-dev git make g++`
+* `git submodule init`
+* `git submodule update`
+* `make release`

-## Create Standalone with Debian
+## Enable Label Printer ##
+
+Just install [reHDDPrinter](https://git.mosad.xyz/localhorst/reHDDPrinter).
+No further settings needed.
+
+## Create Standalone with Debian 11

 Instructions how to create a standalone machine that boots directly to reHDD. This is aimed for production use, like several drives a day shredding.
+* Start reHDD after boot without login (as a tty1 shell)
+* Start dmesg after boot without login (as a tty2 shell)
+* Start htop after boot without login (as a tty3 shell)
+* Upload reHDD log every 12h if wanted

 ### Software requirements
+* `apt-get install hwinfo smartmontools curl htop sudo`

-* apt-get install hwinfo
-* wget http://ftp.de.debian.org/debian/pool/main/s/smartmontools/smartmontools_7.1-1_amd64.deb
-* dpkg --install smartmontools_7.1-1_amd64.deb

-Get your UUID via blkid /dev/sdX
+`bash scripts/install_reHDD.bash`

-systemctl enable reHDD.service
+If you want to upload the logs, edit `scripts/reHDDLogUploader.bash` with your nextcloud token

-systemctl enable reHDDSettings.service
+Add your system drive in `/root/reHDD/ignoreDrives.conf` like:
+```e102f49d```
+Get the first 8 Bytes from your UUID via `blkid /dev/sdX`

+`reboot`

-# Installation
-**[1]** In terminal als root einloggen\
-**[2]** In reHDD_prototype wechseln\
-**[3]** Abhängigkeiten installieren\
-`apt-get install smartmontools`\
-`apt-get install hwinfo`\
-`apt-get install util-linux`
-
-**[4]** reHDD ausführbar machen\
-`chmod +x reHDD`\
-**[5]** ignoreDrives.conf bearbeiten
-##### Ein Eintrag in der ignoreDrives-Datei sorgt dafür das die Software bestimmte Festplatten ignoriert. Dies ist wichtig damit nicht unbeabsichtigt die Systemfestplatte oder weitere Festplatten bearbeitet (gelöscht) werden.
-Beispiel Inhalt:
-```
-/dev/sda:508eff7d-f039-4efb-9e2c-22dffdfdfdfd
-/dev/sdb:07dfffff-c4b6-46e7-9cdf-3cfdfdffd53d
-/dev/sdc:dfff974d-1af2-4dfd-9dfd-a2d8e4c43dff
-```
-Ein Eintrag setzt sich aus zwei Teilen zusammen:
-
-**[Pfad]:[PARTUUID]**
-
-Der Pfad kann mittels `fdisk -l` ermittelt werden.\
-Die PARTUUID kann mittels `blkid /dev/sda` ermittelt werden, wobei `/dev/sda` derzuvor ermittelte Pfad ist.
- 
-# Benutzung
-reHDD starten mit `./reHDD`  (Wichtig ist das reHDD mit root-Rechen ausgeführt wird, entwender als root einloggen oder mit `sudo`)
-
-reHDD sucht automatisch nach allen verfügbaren Festplatten und filtert die zu ignorierenden heraus.\
-Für die verbleibenden Festplatten wird eine Übersicht ausgegeben. 
-Der Nutzer wird gefragt, welche Festplatte bearbeitet werden soll und gibt die Nummer ein.
-
-Beispiel:
-
-```
-hostname@hendrik:/reHDD_prototype # ./reHDD 
-refurbishingHddTool
-created app
-app logic
-search drives ...
