I have a server running Windows 2003, it has a hardware RAID controller (4 disks in RAID5, health all OK)
The server will boot into standard mode or safe mode (from the array) but once windows is running, you cannot access the drive (Windows OS thinks the drive is RAW).
When you attempt to open C drive, it says access denied.
I need to know the direction I should diagnose. Does this sound like a RAID issue, partition issue, or a malware/virus compromising the system? It seems odd that Windows will start... if it were a RAID or partition issue Windows shouldn't start, correct?
