Um Images meines Rechners (u.a. Lenovo T410) bequem ziehen zu können, will ich Xubuntu 14.04.02 auch auf der externen Festplatte installieren. Wenn dann mal ernsthaft was schiefgeht, kann ich von dem System aus Images zurückspielen oder auch Reparaturen vornehmen - so mein Plan.
Es handelt sich um eine 3TB-Festplatte von Intenso. Ursprünglich war sie VFAT-formatiert (eine durchgehende Partition). Die Sektoren sind 4096 Byte groß (nicht 512, wie sonst). Ich habe gelesen, daß bei 2TB Plattenkapazität eine Adressiergrenze mit 512-Bytesektoren ist, die man so wohl überwindet.
Ich hatte von dem Xubuntu 14.04.02 LTS-Stick gebootet. Die Platte hieß in dann /dev/sdb.
Ich habe "Ubuntu ausprobieren" gewählt und später von da aus das System auf der externen Platte installiert. Bei der Frage „Installationsart“ habe ich „anderes machen“ gewählt. Dann habe ich die Platte mit gparted partitioniert und anschließend mit dem Installationsprogramm die Einhängepunkte für / und für /home auf der externen Platte festgelegt. Auch habe ich das Boot-Flag bei /dev/sdb1 gesetzt.
Nachdem ich mit der ganzen Installationsprozedur durch war, kam noch eine Anzeige, daß ich das System jetzt benutzen könnte. Ich habe den Rechner heruntergefahren und neu gestartet und dabei <F12> gedrückt (wie ich es auch zum Booten vom USB-Stick machen mußte), um die Auswahl der Bootgeräte zu bekommen. Aber die externe 3TB-Platte war nicht zur Auswahl angeboten.
Von einer anderen externen Platte mit 1TB Volumen funktioniert das alles (darauf mit Ubuntu 12.04).
Wenn ich danach wieder von der eingebauten Platte /dev/sda1 boote und mir dann die Partition mit der UUID von /dev/sdb1 ansehe, sieht es da so aus, wie auf einer Linux-Systempartition. Es gibt sogar das Verzeichnis /media/verwalter/d97adc7d-5e5c-49ca-86ce-a9ff7706b4e4/boot/grub/ (im Mountpunkt die UUID von /dev/sdb1).
Das System erkennt Folgendes:

Nach googlen zu dem Problem bin ich doch nicht klüger geworden, jedoch ist sicher, daß sowohl die eingebaute Platte einen "msdos"-Bootsektor hat und die externe 3TB-Platte auch:
verwalter@verwalter-ThinkPad-T410:~$ sudo parted -l Modell: ATA FUJITSU MHZ2160B (scsi) Festplatte /dev/sda: 160GB Sektorgröße (logisch/physisch): 512B/512B Partitionstabelle: msdos Nummer Anfang Ende Größe Typ Dateisystem Flags 1 1049kB 30,4GB 30,4GB primary ext4 boot 2 30,4GB 51,4GB 21,0GB primary linux-swap(v1) 3 51,4GB 160GB 109GB primary ext4 Modell: Intenso USB 3.0 Device (scsi) Festplatte /dev/sdb: 3001GB Sektorgröße (logisch/physisch): 4096B/4096B Partitionstabelle: msdos Nummer Anfang Ende Größe Typ Dateisystem Flags 1 16,8MB 11,6GB 11,5GB primary boot 2 11,6GB 17,4GB 5826MB primary 3 17,4GB 3001GB 2983GB primary
Der Lenovo T410 ist auch kein UEFI-bootender Rechner, sondern noch einer mit "legacy"-Mechanismen. Bei https://wiki.ubuntuusers.de/GRUB-Umgebung_analysieren?redirect=no#Festplatten-Aufteilung-und-UUID fand ich unter der Überschrift "Bootsektor analysieren" einen Hinweis auf
sudo apt-get install boot-info-script cl-awk
Dieses Programm habe ich installiert und es liefert folgendes RESULTS.txt:
