I have a Windows Server 2003 box, with 2 identical hard drives installed (not in a RAID array).
For some reason, Windows just stopped recognising the second hard drive. It doesn't appear in My Computer or Windows Disk Management. However, when booting the server up, if I go into my BIOS settings, the BIOS does pick up the hard drive.
What could be the problem? How do I troubleshoot this? Are there any free tools available that I can use to diagnose and fix this problem?
