In CrystalDiskInfo my hard drive is showing "Caution" and Reallocated Sectors Count - 143. I don't know exactly what this means, other than it's bad. Can someone please fill me in?

Alarmingly this is a "brand new" drive.... with data and a movie already on it, and a Power On count of 24 and Power On Hours of 121. It also vibrates like mad, so much in fact that the case itself buzzes from the vibrations.

It's Western Digial, and it's in such a poor state that I doubt Seatools, or any other diagnostic would actually run.

Incidentily... the only reason I bought this one is because my brand new Seagate Barracuda made such a loud noise when spinning that it was unbearable to use. (I'm still stuck with that one, since the store couldn't find any fault with it, and returning it to you under warranty would probably only result in the same "No Trouble Found"...).
 


Netherspark, use this link to see if the sound coming from your Barracuda drive is on this list. If so, contact our support team and if the drive is in warranty it possibly could be returned.

It doesn't make any of those noises. The drive functions perfectly it just makes a constant loud hissing noise, like an old immersion heater (I posted about this a couple of weeks ago, you even replied there). I returned it the shop and they said there were no faults so they sent it back to me. You will do the same tests and likely come to the same conclusion. So unless you can guarantee me a replacement or a refund I might as well just throw it away...

A reallocated sector is a bad sector (unreadable/unwritable) that has been reassigned to another location on the drive. In other words, the drive marks it as bad and makes a note to reallocate it to a good sector. If your reallocations are climbing, then sectors are actively going bad, often due to a crashing head. A 1TB hard drive probably has about 2billion sectors, so having 100-200 bad sectors is meaningless. But if the number of bad sectors is actively climbing, then it's just a matter of time before the drive is completely useless.
