Hard Drive Problem...

So i have a WD 640gb hard drive with my games and iTunes library and some other stuff on there that I feel is going bad. Out of nowhere sometimes if I am playing a game the game will crash and the hard drive will make the usb disconnect sound and it will disappear from "My Computer". Upon restarting my computer it will show up again. I have an identical hard drive and i was wondering if I can make a clone of that hard drive and put it on the other one. Is there a test I can run to make sure my hard drive is the problem before doing anything? Could this simply be just a bad SATA port?
 
This could be a myriad of issues.

Check your SATA cable, check your PSU SATA power cable. It could even be a motherboard issue, but I'm guessing cabling, or PSU issues.

If the OS isn't installed on it, just put the new hard drive in, copy all the files over. Shutdown, pull out old drive, start up, change drive letter on new drive to the old, I'd give it another reboot for good measure and you should be good to go.

You can check the SMART values of the drive for diagnostics.
 
Here is the extended test i ran just now... took a little over an hour and half. I checked the connections and they seem fine.

and here is the smart info for the hard drive..

Pulled from unRAID forum (this should still apply):

Perhaps the most important attribute to look at is the "Reallocated_Sector_Ct", the RAW_VALUE is a count of sectors that have been reallocated/remapped. If a sector goes bad, the drive has the ability to "remap" a spare sector to the bad sector. This is done at a low level, within the drive itself, so the OS doesn't even know it happened. (unRAID actually uses this feature to maintain the integrity of your array.) Each time this happens, the reallocated sector count is incremented. Seeing a few reallocated sectors is not necessarily a bad thing, but seeing that number start to go up is often a sign that the drive is failing. Anytime you see a value other than 0 you should closely monitor the drive. If the number holds steady and does not increase even after several parity checks, your drive is likely okay. But if it seems to be going up by even 1 or 2 at a time, start to be concerned. This is likely the first hint that the drive is failing. A special note about reallocated sectors, bad cabling CANNOT cause reallocated sectors to occur.

An equally important attribute is the "Current_Pending_Sector", the RAW_VALUE is a count of suspect sectors pending reallocation. It should ALWAYS be zero. If not, then you will probably (but not always) see the Reallocated Sector Count increase in the future, when this does return to zero. Before remapping a suspect sector, it tests it one last time, and *may* pass it and not remap it. (There are good reasons why it is designed to work this way.)

EDIT: This is probably more helpful: http://en.wikipedia.org/wiki/S.M.A.R.T.#Known_S.M.A.R.T._attributes

So what other test's do you recommend I do to resolve this issue? This problem that I am having only happens once in a while... which is really strange..

I don't think you need to run any other tests. I would, however swap out the Sata cable, and/or power connector. Are you using a standard sata power connector, or a molex to sata converter?

And just to confirm, the screenshots you took above don't show any reallocated sectors or pending reallocations.
