I have a Dell Precision 490, and when I boot it up, it will say no hard drive attached.  I remove the side of the case, then re-attach it, and it is able to find it.  Then after a few reboots, it will say it can't find the hard drive, and I just remove the side of the case again, then re-attach it.  I don't see this being a long-term solution.  How can I fix this?

 What are you re-attaching, power or data cable?  IDE or SATA.  You could have a defective connector on the cable you're using, so if you can use a different cable, that would seem to be the best thing to try.


Everyone with a computer should back his system up to an external hard drive regularly.  :thumbsup:

Prob have a loose hdd cable or something pulling on it.

 

Does your inside case look like this?

ground yourself and power down the system, once done, check each of your cables, and see how easy the hdd cable comes out, 

check the end points on the cable to see if their cracked or broken as well. 

If you have a spare cable swap it in for it.

Yes, it does.  I will take a look into it.

So I pulled out the hard drive bay, and there were no hard drives inside.  Where else could it be?

Did you pull the cage that includes the optical drive? The hard drives in the image anoladel linked to are located in the upper right behind the fan.

Sorry, not sure what your saying.  I pulled the handle out where the two hard drives are suppose to be placed, and there was nothing in there.  And when you say they are located in the upper right behind the fan, the only fan I see is the power supply.

In the upper right of the image is a fan. This is the memory fan as shown in the link below. When you opened the side panel of the computer, there is a panel that swings away which is supposed to be the hard drive cage. Do you have this?

Edit: The only other location the hard drive would be is under the optical drive behind the front bezel of the computer.

I'm sorry - I thought you meant in the top right corner of the inside, not the panel.  Yes, I have this.  I think my hard drive is in the upper left of the desktop because there is a sata port running into it.  It does not look like a HD from the back, but it can be pulled out.  In this image, my HD is where the DVD drive is.  My dvd drive is one below that.  I have a handle with a lock that I can pull out.

You are right if you see another drive above the DVD drive. This would be the hard drive. They didn't bother to put it in the pull out tray.

Why wouldn't they put it in the easier to access area?  Also, how can I get it out?  Do I have to pull the front off?  There is a round key slot.  Do I have to unlock that first?

I found the users guide with extra detail on removing the components. It should help.

 

Edit: Once you get the hard drive removed, I would locate it to the swing out tray if your SATA cable is long enough. From quickly looking at the manual, it looks like you have to remove the front bezel to get at the hard drive.
