Last time I was using windows it crashed because of some application I was running leaking memory and getting to around 7GB. I couldn't even open Task Manager so I just reset the PC. After rebooting in Ubuntu (14.04) however, I was not able to access the partition at all, getting an error:
Error mounting /dev/sdb2 at /media/username/Windows2: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000" "/dev/sdb2" "/media/username/Windows2"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error Failed to read NTFS $Bitmap: Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details.
I tried ntfsfix, but it found no issues:
user@Desktop:~$ sudo ntfsfix /dev/sdb2 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/sdb2 was processed successfully.
Note that the other two partitions on the same disk (one of which contains the bootloader) seem to be working fine.
Windows won't start, displaying a self explanatory BSOD, "UNMOUNTABLE_BOOT_VOLUME" instead.
I tried booting through a recovery disk and doing chkdsk /r. It took an entire day and seemed to find quite a few errors but nothing changed.
I do not know what to do. This is a WD Blue from november 2013, no not that old. The data on it is extremely important to me and I don't want to lose it for any reason.
Is there any way to get it to work, at least to mount it in Ubuntu? Might the issue be the SATA controller? I have an Asus Sabertooth x79, which is relatively old of course. Should I try dskchk /f instead?
Edit: I user smartctl to check my drive's health status. The results show that it's pretty good at least for now, so this is no hardware failure.

Also I did another chkdsk from the windows recovery CD, with /f option this time. It seemed to work but again it did not change anything.
When I tried booting windows in safe mode, it loaded a lot of the drivers ( meaning the partition still hasn't been entirely trashed) and then BSOD'd after freezing for a few minutes. Ubuntu was also not capable of mounting the partition.
