windows cannot read a partition

while i booted my system windows asked me to check file system on D drive,i was surprised as i shut down the system perfectly last time but still when i allowed to chek it was showing messege “lost link at cluster 12345 corrected ” and the counting went beyond 1,50,000 taking about 1 hour. i just stopped this and restarted system this time not checking drive.and after log on the label of d: drive was changed and windows was not reading anything from that drive and showing strange fonts in the name of folders and files .my disk space which had a free space of approx 13 GB was shwing only free space of 100 MB showing warning messege of low disk space.
how can i fix the problem?
