Still Having HDD Problems

[DayTrader]

Today, my computer got a BSOD. When it restarted, it said the disk failed to boot and to enter the Windows disc. Well, I unplugged the sata cord to one of my drives (the non-boot drive) and it started right up. So I then plugged it back in but this time on a different sata port and it again booted up. I'm not real sure what to think of this. Is my HDD failing? If so, why does changing ports make it work? This happened a couple weeks ago, and when I changed ports (I have several to choose from), it worked fine up until today. Any ideas?

It just restarted again and this time the message on the black screen says,

A disk read error occurred
Press Ctrl+Alt+Del to restart

Sounds like it's going bad. Try and repair windows and get any data you need off the drive.

Thanks for the reply. That's what I was afraid of. Luckily I was able to stay up long enough to back up the hard drive. Currently, I am running only my boot drive with no problems yet.
