hardisk unformatted in 2003 server

have a 60Gb seagate in a client’s server as D: drive. was working for the better part of 6 months, but computer mgmt can c it but shows it as RAW format. On connecting the PC to other workstations i can access info on it (NTFS). Very vital to the netywork ‘cos i have roaming profiles, user data and backup programs on it. What can i do to get the server to see this drive? connected another hardrive to it and compmgmt.msc found it easily. thanks in advance
