Befehl '''fdisk''' [Optionen] DATENTRAEGER


  #fdisk -l
  '''fdisk (fixed disk) ist ein Kommandozeilen-Programm zur Partitionierung von Festplatten. fdisk gibt es für Windows und Linux. Man kann fdisk in Linux benutzen, um Partitionen anzuzeigen, anzulegen, zu manipulieren oder zu löschen'''.


Disk /dev/sda: 931,5 GiB, 1000204886016 bytes, 1953525168 sectors
Um fdisk zu benutzen, geben Sie fdisk und den Namen der Festplatte, die Sie partitionieren wollen, ein. Dies wird das fdisk Prompt eröffnen. Um beispielsweise die primäre SATA Festplatte zu partitionieren, benutzen wir den folgenden Befehl
Disk model: SAMSUNG HD103SJ

Created a new DOS disklabel with disk identifier 0xdfca4904.
 
Command (m for help): '''g'''
 
Created a new GPT disklabel (GUID: 748568BC-EC8C-F34A-B822-45C2E267CFFB).

*Am Anfang des Datenträgers werden 2048 Sektoren ungenutzt gelassen, um ein optimales [[Linux:Software-RAID:Anlegen#Alignment (Ausrichtung)|Alignment]] zu ermöglichen.
*Der erste Sektor der Partition soll bei Sektor 2048 beginnen.
**'''2048''' oder einfach "Enter" drücken, dann wird der Standardwert (''default'') genommen.
*Am Ende des Datenträgers werden auch Sektoren ungenutzt gelassen, denn falls nach Jahren ein Datenträger ausfällt und keine baugleiche Festplatte mehr beschafft werden kann, wird das RAID zum Datengrab.
*Werden Sektoren am Ende ungenutzt gelassen, kann ein Datenträger, der einige Sektoren weniger hat, problemlos verwendet werden.

fdisk (fixed disk) ist ein Kommandozeilen-Programm zur Partitionierung von Festplatten. fdisk gibt es für Windows und Linux. Man kann fdisk in Linux benutzen, um Partitionen anzuzeigen, anzulegen, zu manipulieren oder zu löschen.

Um fdisk zu benutzen, geben Sie fdisk und den Namen der Festplatte, die Sie partitionieren wollen, ein. Dies wird das fdisk Prompt eröffnen. Um beispielsweise die primäre SATA Festplatte zu partitionieren, benutzen wir den folgenden Befehl
