How do I update raid 5 configuration

I downloaded updates from windows website, after rebooting I couldnt login because the system was saying active directory missing. I have a raid 5, configured partition D where the active directory database files were kept. There is also a C drive where my OS is.
The server requested me to log onto Directory service restore mode , but I cant. So I removed the C drive where the OS is and then reinstalled. I can now see the other raid 5 array as unallocated.

How do i activate this as I cannot access the raid partition without losing my data

please send mor information about your raid controller ,i hope you be right and your active directory database be in d: because usually all windows server keep active directory database in ntfs partition that os install on it
usualy after installing proper driver for your raid controler you can see raid volume in device manager under Drive branch ,and then you have to go to diskmanager and import that volume ,that was general story
you need more detail to start it ,but befor it is better send information about your hard ware (raid controler,howmany hard drive ,what size ,...)

The active directory database was intentionally saved in D so that if the OS crashes , we will still be able to move the array to another server and restore the active directory.

The disk management screen is not giving me any option to to import that volume. see attached screen shot. Under device manager, The SCSI and RAID  controller drivers listed are

Adaptec AIC-7901 HostRAID driver and
LSI logic Megaraid SCSI 320-1

I would be greatful if you can help me bring the RAID 5 up without losing any data

i think partition on raid volume is deleted because
You can convert only empty, unpartitioned disks (raw drives or empty MBR drives) to the GPT format. To convert a volume that contains data, you must first manually delete the partition.
but it is not important there are alot of utility that you can recover partition table ,if your data is important for you at first you have to take an image backup of your raid volume
do you know how can i send 100meg file to you (utility for get image and recover lost partition)attachment limited to 50 meg
or you can find Acronise for get image from your raid volume and you can download
1)))))Ontrak Easy Recovery Pro (http://www.ontrackdatarecovery.com/file-recovery-software/)
OR
2))))) pc tools (http://www.pctools.com/file-recover/?ref=ov&utm_source=ov&utm_medium=cpc&utm_term=file-recover&OVRAW=Easy%20Recovery%20Pro&OVKEY=easy%20recovery%20pro&OVMTC=standard&OVADID=34368999512&OVKWID=248534009512)


you can recover all data even format harddrive 10 times

Thanks a lot for the advice. Tried both tools you gave me but the machine keeps hanging. I want to recover data from a raid array of 4 disks, total 420Gb. I have a Xeon 3Ghz processor with 2Gb Ram. If I could get my Windows 2003 Standard edition to allocate a drive letter I could be happy. Is the hard drive too big to be recovered?
