Ubuntu cannot be mounted when using a mobile hard disk (solution)

Ubuntu cannot be mounted when you use a mobile hard disk (solution): When you use ubuntu11.04 and then copy the hard disk, an abnormal shutdown occurs. After restart, the hard disk cannot be mounted. the following Error occurs: Reference "Error mounting: mount exited with exit code 13: $ MFTMirr does not match $ MFT (record 0 ). failed to mount '/dev/sdb1': 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_eahaabpc3 ). please see the 'dmraid 'documentation for more details. solution: (1) follow the recommended method to go to windows win + R (or directly find the 'run')-> cmd-> doscommand line window (2) find the volume name of the mobile hard disk in your windows. My files are F: disk (3) type in DOS, and chkdsk F:/f (4) unmount the hard disk safely (5) re-insert the hard disk to test whether the file can be transferred successfully (6) Insert the hard disk to ubuntu for testing. Solve the problem! Note: what is the role of the command cmd-chkdsk/f? Hard Disk scan, used to check hard disk errors. Add/f or-f to the end to indicate that the error is automatically fixed during the check/x table-type forced check. If the hard disk is in use, remove the hard disk and scan it. /V indicates that the complete folder path and name are displayed in the fat/fat32 file format. /I and NTFs index items for the minimum intensity check/C is used to skip the folder structure loop check.
