Pekny den,
Snazim sa obnovit data z NTFS disku, disk sa sklada z 3 particii:
sdc1 - 1.5 GB - toto ma nezaujima
sdc2 - 116 GB - particia ide precitat vo Windows aj Linux a teda data z nej som uz zalohoval
sdc3 - 115 GB - z tejto particie potrebujem dostat data - vo Windows ani v Linuxe nejde precitat
Ak spravne chapem vypis z ddrescue tak bol schopny skopirovat 99.9% dat z sdc3.
Taktiez photorec bol schopny obnovit cca 95 GB obrazkov a videii - v obnovencych datach je ale pekny gulas (vsetko v jednom adr.), preto by som sa rad dostal ku strukturovanejsej podobe.
Povodne som skusal aj testdisk avsak ten nenasiel ziadnu inu particiu okrem tych ktore tam uz su, a na sdc3 mi nevylistoval ziadne subory.
Myslim ze disk je teda po fyzickej stranke OK, a zrejme je nejakym sposobom poskodeny file system.
Zatial som teda urobil nasledovne:
- vytvoril image z sdc3 cez ddrescue
- spustil ntfsfix nad sdc3
- spustil chkdsk nad sdc3
- cez photorec vytiahol data z sdc3
Co mozem este vyskusat? Ma zmysel skusit napr gpart (nemylit s gparted)?
Viem si nejakym sposobom urychlit nasledne analyzi v dlasich nastrojoch (vyuzit log z ddrescue a pod?)
Po tomto mi NTFS nepride moc spolahlivy (ano viem treba zalohovat), aky je Vas nazor, je lepsie pouzit ext4 alebo radsej BTRFS resp ZFS ?
Dakujem za kazdu radu, nizsie pripajam vypisy

NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.
