[kwlug-disc] Hard disk smartctl errors

[Khalid Baheyeldin]

/dev/sdb2 is the problem partition.
Yes, it is the 3rd partition, but not the last one.

# fdisk /dev/sdb

Command (m for help): p

Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x8baa29fc

   Device Boot      Start         End      Blocks   Id  System

/dev/sdb2          409600   926949375   463269888    7  HPFS/NTFS/exFAT
/dev/sdb3       926949376   976560127    24805376    7  HPFS/NTFS/exFAT
/dev/sdb4       976560128   976771119      105496    c  W95 FAT32 (LBA)

When I try to mount the partition, this is what I get:

# mount /dev/sdb2 /mnt/tmp/
ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to read hiberfil.sys: Input/output error
Failed to mount '/dev/sdb2': Input/output error
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.

Looking at gddrescue examples, they all assume another disk with a
spare partition to recover to.

Not sure if that is the only way. Man pages are very basic. Checking
the info documents ...
