750 Gb Samsung crknil - kako do podatkov?

Zdravo!

Kakšno leto star disk iz Hoferja v zunanjem ohišju je nenadoma odpovedal poskušnost in v windows javlja, da ni formatiran. Gor so za lastnika pomembni podatki :)

Disk sem vzel iz ohišja, ga priklopil direkt v mašino in pognal ubuntu live CD.

Tole javi:

Fdisk nima problemov s prepoznavanjem:

sudo fdisk /dev/sda

Mountat se ga pa vseeno ne da ...

sudo mount -t ntfs /dev/sda1 /mnt/disk1

Error reading $MFT: Input/output error

Smatram, da je elektronika OK. Še kakšna ideja, kako do podatkov?

Lp,
b.

Hvala za namig, že iščem!

Trenutno gre čez disk HDD regenerator ... Slabo kaže. Slabih sektorjev ko dreka. Sicer je dosedaj še vsakega uspešno popravil, ampak traaaaaja. Me prav zanima koliko bo uporabnega ko konča. No ne vem, ker če prav razumem uro zgoraj desno ima pri tolikšni škodi dela za več kot 6 dni ...

Pa boš lahko potem prebral podatke?

Zdravo! Program je z delom na dobri polovici, našel & popravil preko 1500 napak in naj bi končal čez dobre 4 ure (upam!). Zanima me, kako naprej z ostalimi testi. Se lahko bolj specifično pove, kateri "nek" test za MBR in "nek" test za particije s Hiren's boot CD se priporoča? Se bojim, da odkrivam področje, o katerem nimam pojma :/

Osebno bi najprej pognal HDD Regenerator, ki je neodvisen test bad sektorjev glede na OS.
Potem pa po vrsti nek test za MBR, potem nek test iz Recovery testov za particijo, če je z njo ali njih vse ok, nato še File Recovery....
Vse imaš na Hiren's BootCD-ju.

Ok, thx!

Definitivno bi probal, če ne drugega da se malo poigram, a nimam nobenega tako velikega diska da bi naredil dd. Sem poslal lastniku msg če bo on kaj ukrenil v tej smeri, sam ne grem v stroške.

Hvala!

Zgleda bo res tako najbolje. Program je končal in popravil preko 2000 napak, delal pa dobrih 6 ur. Priklopil sem na mašino, pa ni bilo sreče, javi da strutura ni berljiva. Zdaj sem še 1x pognal HDDregenerator in mi je takoj našel & popravil slab sektor. Najbolje da res počakam, da se nabavi disk, naredim image in se igram s tem.

Hvala za nasvete in predloge.

Lp,
b.
