my laptop running ubuntu 11.10 was updated to 12.04 but failed halfway through update. i had no option but to turn the laptop off as it had frozen and back on again to find the laptop non functioning. i then made a ubuntu 12.04 boot cd to boot the laptop to save my files from the internal laptop hard drive to the external hard drive off my pc running windows xp via usb no problems there but then i proceeded in a very tired state to install ubuntu 12.04 from the cd i choose the partition method the first option of 3 to keep files and folders i started the install and a few seconds in noticed it was writing to my external usb drive got scared and pulled the usb lead then proceeded to do a normal install of ubuntu 12.04 on my laptop but now ubuntu will not open my external 250 gb hdd but does recognise it as such in disk utility. instead of mounting it gives this message.
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_eahaabcc1). Please see the 'dmraid' documentation for more details.
windows does not recognise it as anything neither does easus. please help i desperatly need all my files back i feel such an idiot.
