External drive attached to a DVR

I can't believe this, my DVR has eaten another hard disk! This time it
was a 1TB Seagate, rather than a 500GB Hitachi. I bought the Seagate
just 12 days ago to replace the Hitachi. What the hell is this DVR doing
that's so hard on hard drives? The new drive all of a sudden has 312 bad
sectors!

Okay, now the 3rd drive is starting to show signs of problems. The DVR
thought it was offline for some reason last night. This is also the same
sort of refurbished drive as the 2nd drive. I took it off the DVR ran it
through the laptop, and SMART reported a lot of Read Error Rates and
Seek Error Rates. However, no Reallocated Sectors yet, so HD Sentinel
thinks the drive is fine. Are these errors enough for me to go back and
exchange it yet?

What would cause the Read Error and Seek Errors to occur? Cabling?
Power? Physical surface defects?

Not if its a seagate.

With seagates its just a different way of reporting what all drives see.

Nope, not if its not a seagate.
Power?
Yes.

Physical surface defects?

Nope.

I see, well it is a Seagate, don't remember which one anymore, it's a 1
TB model.

OK, no evidence of a problem yet except the drive going offline.

That is evidence of a flakey power supply in the Vantec.

The DVR is a Cisco/Scientific Atlanta 8300HD, while the external case is
a Vantec Nexstar CX USB2/eSATA.
