Πρίβλημα με σκληρό

[borror]

Παιδιά έχω μεγάλο πρόβλημα. Ακούστε πως έχει. Έχω έναν σκληρό μέσα σε ένα εξωτερικό κουτί και ενώ δούλευε μια χαρά όταν τον ξαναάνοιξα μου βγάζει ένα error. Έχει ένα partition μέσα. Δείτε τι βλέπω στο shell. Μήπως έχετε καμιά ιδέα?

 

>[root@myhost steevi]# fdisk /dev/sdb

The number of cylinders for this disk is set to 19457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
  (e.g., DOS FDISK, OS/2 FDISK)

Command (m for help): p

Disk /dev/sdb: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Command (m for help): q

[root@myhost steevi]# mount /dev/sdb1 /mnt/Usb-storage/
mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
      missing codepage or other error
      In some cases useful info is found in syslog - try
      dmesg | tail  or so

[nske]

Ποιο είναι το ακριβές μήνυμα που γράφει ο driver στο kernel log; (όπως προτείνει η mount μπορείς να το δεις με την dmesg(8))

[borror]

ον δοκίμασα τον σκληρό και στο arch στο laptop και στο kubuntu live cd το 7,04 και τίποτα. Μήπως ξέρετε κάποιο tool για recovery partition? Πιθανόν αν υπάρχει κανένα να κάνει δουλειά. Το fs του partition είναι reiserfs. Το μήνυμα που βγάζει με το dmesg είναι.

Το partition δεν υπάρχει λόγος να έχει ζημιά, μόνο το filesystem (reiserfs) που είναι διαμορφωμένο πάνω του. Δοκίμασε:

 

># fsck /dev/sdb1

 

Επίσης εγκατάστησε και τα smartmontools για να δεις μήπως τυχόν το corruption ήταν αποτέλεσμα βλάβης του σκληρού.

Να τι μου βγάζει. :neutral::neutral:

Δοκίμασε να κάνεις αυτό που σου προτείνει

 

(fsck --rebuild-sb /dev/sdb1)

Μπα. Δεν μου το δέχεται :neutral::neutral:

Μήπως είναι κάποια άλλη εντολή? Κοντεύω να τρελαθώ. Και τα αρχεία που έχω μέσα τα μαζεύω γύρω στα 8 χρόνια

Για κάποιο λόγο δεν πήρε το σωστό fsck, δώσε του το ακριβώς τότε:

># fsck.reiserfs --rebuild-sb /dev/sdb1

[dpetka2001]

δεν πρέπει να τρέξεις "fsck --rebuild-sb /dev/sdb1" αλλά "reiserfsck --rebuild-sb /dev/sdb1"...εκεί υπάρχει η επιλογή --rebuild-sb...

[borror]

Το έκανα αυτό και μετά έδωσα ένα fsck /dev/sdb1 μου έβγαλε αυτο.

Οπότε του έδωσα ένα reiserfsck --rebuild-tree /dev/sdb1 και θα postαρω αύριο για αποτελέσματα γιατί αργει πολύ. Thanks για όλα. Καλό βραδυ.

Ok παιδιά. Τώρα ξύπνησα και είπα να δω πως πάει. Τελείωε το rebuild tree και όλα δουέύουν ρολόι. Τον κάνω mount κανονικά. Χίλια ευχαριστώ για όλα. Με σώσατε:grin::grin:
