I have recently changed by RAID Arrays from an "embedded" setup (using on-board controllers) to a dedicated Raid Controller plugged into a PCIx8 slot. I purchased the Adaptec 5805. It has two (2) connectors; CN0 and CN1; each of which can accept 4 drives = 8 total. I am using six drives as follows:
CN1 = Raid 0 with two (2) WD 300 Raptors in RAID-0 with my OS and apps on that array
CN2 = Raid 5 with three (3) Seagate ST31500 (1.5tb) drives in RAID 5 for all of my data
Both RAID Arrays were built in the Adaptec BIOS and are confirmed, verified and optimized in BIOS. When I boot into Vista and run the Adaptec Storage Manager, both Arrays show up there, too -- and seem to be just fine. It shows volumes in "optimal" status (see attached screen shot).
However, I am unable to "see" the Raid-5 Array in Vista-64's Disk Management utility, thus I am unable to create a partition and format it for use (see second screen shot)
I am running Vista-64 with 8GB of RAM. I am using Adaptec Storage Manager 6.0x and that utility and I have the most recent BIOS from Gigabyte for my mobo. These arrays worked fine when they were used on the "embedded" controllers. Now, Vista can't see them all with a dedicated controller.
Various screen shots showing device manager, driver versions, etc. are all attached.
Any help is greatly appreciated!
