I've had similar errors before, and there was one simple thing to solve it... Since you installed Ubuntu, have you started Windows? The most common cause is that Windows crashed, something went wrong when Windows unmounted it, or you turned the power off without shutting it down. The easiest solution is to normally start Windows, then shut it down, letting it cleanly go into reboot, or power off. This will take the mark of it being in use off, and should allow you to mount it.
However, if this does not work, there is one alternative I know of. However, I neither endorse this, nor suggest it, but it's an option...
mount -f ntfs-3g /deb/sdb1 /mnt/d
The -f forces it to mount, even if there are errors.
