hdd showing in Computer but not in device manager

Hi there I have a very strange thing going on here.
I have two hard drives one 1TB (which is my main hdd which I have windows 7 on) and my 500GB hard drive where my stuff is on. Now here is the strange thing, Although I can enter my C drive (via Computer) I cannot see it in disk mangement or in device Manager. Which in turn does not allow my to upgrade to a diffrent higher version of windows7 .cause the only drive that is showing is my D drive. Help would be very much accepted. Is windows 7 preventing me from making any kind of changes to my C drive?

You might have a permission problem with the drive :

Right click on the drive in Computer - properties - security - advanced - owner - edit - then change owner to yourself.

I change owner and it still does not show up . I used a program from seagate to check my serial number for the unit and they both came up.

After googling around I found away to (at least) to see my main hard drive in device manager but it says Currently, this hardware device is not connected to the computer. (Code 45)
To fix this problem, reconnect this hardware device to the computer. But this is odd since I can access my c drive normally from "Computer"

Recommended resolution

This error occurs if a device that was previously connected to the computer is no longer connected. To resolve this problem, reconnect this hardware device to the computer.

No resolution is necessary. This error code is only used to indicate the disconnected status of the device and does not require you to resolve it. The error code resolves automatically when you connect the associated device to the computer

The following information is for the advanced user.

If Device Manager is started with the environment variable DEVMGR_SHOW_NONPRESENT_DEVICES set to 1 (which means show these devices), any previously attached (NONPRESENT) devices are displayed in the device list and assigned this error code.

Explanation of error codes generated by Device Manager in Windows XP Professional

I would check to see if your connections are correct and reconnect and also have you adequate power supply - PSU - I just looked at your system specs and a 750w should be OK - maybe the watercooling is using too much power - seems you would know, just a suggestion.

Logical drive shows under computer but not under storag

A variation on what Andyc7454 is experiencing. After I finished the installation of Office 2010 that created a "Q" logical drive to do the install. I am left with a "Q" drive that shows under my computer completely empty but does not show under Administrative tools/computer management/storage. Yet, the drive letter Q is unavailable under storage for reassignment.

When I double click the drive to open it under computer, I get the box saying "access denied". I tried to take over ownership but it won't let me. I tried to do a format, chkdsk but again it wont let me. It will open the property sheet but thats all I am allowed to do. One more thing, I can change the volume name and the volume location is unknown.

How do I get rid of this drive?

Reboot with the W7 DVD in the drive and start installation Of W7, and when you reach custom install - delete the partition your trying to install W7 ultimate to, and recreate it in the unallocated space, and then continue to install to the new partition. This should fix any problems its having with the drive if its available, if its unavailable you could try running the repair utility.
