Windows 7: External HDD: Bad Sector?

So I have a 1 TB external HDD (USB 2.0/eSata, external power source) and I think it might have a bad sector, but I don't know for sure. So I was wondering if anyone else has encountered this or know of an issue similar to mine.

So originally I had this HDD split into 2 partitions: one for music/movies/media related items (FAT32), and one for programs/software/documents (NTFS). The media partition being much bigger than the "Software" partition.

So I was backing up one of my computers and putting it into the "software" partition and I was only putting about 1gb of backed up data onto it. Then all of a sudden in the middle of the transfer is stops transferring and it says the Software partition cannot be read. I try this a couple more times and the same thing happens.

I then try to transfer the backed up data to the Media partition and it works fine.

So then i try to run the CMD prompt "chkdsk" on the Software partition and it runs fine. But when I run "chkdsk /r", where the "/r" tries to recover bad sectors, and it fails to complete (gets stuck at a random percentage whenever I run it, but usually <15%). And I also notice my HDD starts making a loud spinning-clicking noise.

I run the same "chkdsk" on my Media partition and it runs fine. So my best guess is that somewhere maybe I formatted the Software partition wrong and some sector must have gotten corrupt or something like that?

So what I'm looking for is an answer of whether or not the sector of my external HDD is corrupt and whether or not there is a fix for it.




===================================

for those tl;dr people...
-1TB Externl HDD (with a separate power source)
-2 Partitions, 1 partition has trouble reading/writing to, the other one is perfectly fine.
-One partition was formatted FAT32 (good one), the bad one was formatted NTFS
-cmd> "dskchk" on the bad partition is fine. But "dskchk /r" causes the HDD to spin and make clicking noises for about 2 minutes.
-"dskchk /r" on the good partition runs fine.
