When I tried mounting an external hard drive connected via usb I got the error quoted below. So far I've tried using ntfsfix and chkdsk. My operating system is Arch Linux and the drive is NTFS formatted.
Error mounting /dev/sdb1 at /run/media/ssb/HITACHI: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=100,dmask=0077,fmask=0177" "/dev/sdb1" "/run/media/ssb/HITACHI"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to calculate free MFT records: 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.
Here's the output of
sudo ntfsfix /dev/sdb1:
$ sudo ntfsfix /dev/sdb1 Mounting volume... OK Processing of $MFT and $MFTMirr completed successfully. Checking the alternate boot sector... OK NTFS volume version is 3.1. NTFS partition /dev/sdb1 was processed successfully.
