Boot drive not listed in device manager but system boots

[Norm1510]

Drive c: (my boot drive) is not listed either in device manager or in the storage management console of Windows 7. There are 4 unique hard drives in my system. Drives D: E: and F: are listed correctly. There is no entry anywhere in either device manager or the management console for the C: drive yet the system boots OK and the drive and its contents are properly shown in Windows explorer. Using the rescan command in device manager has no effect. The major problem is that programs that depend on these listings (such as Norton Ghost) cannot find the C: drive and do not work. I'm not quite sure when/how this problem first appeared but I know that it is relatively new (within the last month or two).

I did a quick check with the C: and F: drives and there was no problem sharing these drives. I am on a home netwirk with only one other user (my wife) currently logged on. Since I normally don't leave my drives shared (my network is both wired and wireless) I disabled sharing again once my test was completed.

On another site on which I've been posting someone has identified the problem as a root kit:

This is caused by TDSS root kit and here is a Link to the one rookit cleaner that worked for me. http://support.kaspersky.com/viruses/solutions?qid=208280684. After Running TDSSKiller.exe and removing the rootkit, the Harddrive was again listed in device manager and Disk management. I scanned the system again with several Scanners all came up clean.

This is the final answer. Problem has been solved.

Win 7 installs to non partitioned space during install, so if you made a 100 GB partition during setup then win 7 would not of installed to it and installed in a new partition it made.

In explore it will not show you an empty drive by default. Go to tools menu and folder Options and then view and select the show empty hard drive in explorer.
