speed

The hard drive is used to do BT with uTorrent. Recently uTorrent began to report there is a "I/O Device error", then I use HD Tune to test it, it turns out the transfer rate is only 16 MB/sec. At the same time, I have a similar hard drive tested, it rates as 120 MB/sec. They are both 7200rpm desktop hard drives.

I used chkdsk to fix it but the rate didn't change.

Is this a symptom of hard drive failure? Should I backup the content on the disk ASAP or is there any other tool can fix it or diagnosis it?`
