[linux] Re: Moeilijkheden met het inlezen van een externe harde schijf

[Bas Roufs]

Beste Paul en allemaal

Dank voor deze suggesties - ik loop ze hieronder langs.

Op zich vind ik het prima om ook dingen te doen via een terminal. Maar
een enigszins werkbaar programma voor bestandenbeheer ken ik nog niet
in in die vorm. 'Midnight Commander' vind ik wat omslachtig. Daarom
kom ik toch vaak bij Dolphin uit.

bas op Viaconsensus1:~$ cat /proc/scsi/scsi

Er komt inderdaad een waslijst schijven en USB poorten tevoorschijn.
De EXTRA vermelding die op deze lijst verschijnt als de externe HD
aangesloten is, is deze:

Host: scsi3 Channel: 00 Id: 00 Lun: 00
Vendor: ST350063 Model: 0A               Rev: 3.AA
Type:   Direct-Access                    ANSI  SCSI revision: 00

Als ik de externe HD heb aangesloten, dan krijg ik deze sdg
vermeldingen als extra vermeldingen:

major minor  #blocks  name

   8    96  488386584 sdg
   8    97  383486670 sdg1
   8    98  104899882 sdg2

Deze '...tail - 100' commando' s leveren allebei dezelfde waslijst
foutmeldingen op. Zie hieronder.

Achtereenvolgens probeerde ik te 'mounten' en 'umounten': sdg, sdg1,
sdg2. In alle drie de gevallen kreeg ik dezelfde foutmeldingen zoals
die hieronder:

bas op Viaconsensus1:~$ mount sdg/mnt
mount: can't find sdg/mnt in /etc/fstab or /etc/mtab

bas op Viaconsensus1:~$ umount sdg/mnt
umount: sdg/mnt is not mounted (according to mtab)

Conclusie: de 3 partities van de externe harde schijf worden herkend.
Maar toch is er iets waardoor ik er niet mee kan werken tot nu toe.
Zijn er suggesties?

Alvast bedankt.

Bas.


Foutmeldingen bij  "tail -100 /var/log/kern.log" en "dmesg | tail -100"
