Ovako imam problem sa externim HDD do jučer sam mogao na njemu čitati ,pisati,brisati ali danas veliko iznenađenje ne mogu ga mountati ,nekad ga vidim na gpartedu ili konzoli ,a nekad ne. Inače taj hard mi je služio godinama za backupe i sve bilo ok.
Jako mi je bitno da ga uspijem učitati na njemu mi je sve.Danas cijeli dan googlam i tražim neka riješenja ali uzalud.
TOSHIBA/HDD je u pitanju i formatiran je na ext3 davno prije dok ext4 nije bio aktivan.
Na ispis u terminalu : dobijem ovo

I tako mi je sad muka postao sam bledunjav nakon ovog svega ,ako netko ima neki prijedlog pametan slobodno mi recite.

i onda ga pregledavaj. spasi sve podatke za svaki slučaj.

• mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
  missing codepage or helper program, or other error
  
  In some cases useful info is found in syslog - try
  dmesg | tail or so.

vidi na portalu članke o Clonezilli ili PhotoRecu pa njima pokušaj spasit sve podatke...ili pričekaj da ti se javi netko s više iskustva. u svakom slučaju, sretno

ja sam isto tako prošao....uveče disk radio a ujutro mrtav i otišle mi sve slike koje sam imao....
uglavnom bili isti simptomi kao i kod tebe....

Probaj mu prilikom mounta dodat ext3 fs tip i mountat ga kao read-only: Ako to ne uspije, probaj provjerit disk sa badblocks programom:

Evo upravo kopiram podatke na nekoliko HDD , problem sam uspio riješiti sa fantastičnim alatom

(http://www.ultimatebootcd.com/) Ova tema se smatra riješenom .

Hvala svima što ste mi pokušali pomoći ,srdaćan pozdrav svim članovima foruma.
