I have Ubuntu and Win7 both installed on my laptop.

I was working on Windows when I dropped the laptop from about 3.5feet in air. Ever since, windows is unable to boot. But Ubuntu works just fine.

When I ran SMART, it shows me there are a few bad sectors. I'm attaching a screen shot of the report.

Can anyone suggest what must be done?

Here's the image:

Check the badblocks command from the Linux command line. Refer to the man page for detailed information: man badblocks.

As an example, I run /sbin/badblocks /dev/sda on a monthly basis to find problems. I never had to use this tool to actually fix bad sectors, thats why I have to point you to the man page.

BTW: You cannot fix the NTFS filesystem from Linux, you need Windows for that. Yuo can however check the disk for bad blocks as described and it can do some relocation of bad sectors (which doesn't affect the filesystem).
