I was having only 15 GB space allocated to LINUX. I wanted to have more space available to linux. So I just re sized one of my ntfs partition using GParted. But after resizing I am not able to open the partition neither in Ubuntu nor in windows. OS: Dual Boot Win7/Ubuntu 10.10 The error message i get is the following: Error mounting: mount exited with exit code 12: Failed to read last sector (395458824): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sda5': Invalid argument The device '/dev/sda5' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

This might do it:

sudo ntfsfix /dev/sdxy

Boot from windows installation CD and use recovery console to fix that.
