Raid controller not detecting new hard disk after bios

    This ones baffling us....

    We have a computer running an Adaptec SCSI card 29160 with an adaptec SATA HostRaid driver.

    Basically there are 2 hard disks in the raid running as a mirror

    We recently replaced one of the drives as the adaptec storage manager said that the raid was degraded and one of the hard disks had failed

    The issue we have is that the new hard disk shows up in the adaptec bios section and will allow us to format it etc but when we boot into windows (SBS 2003) the hard disk does not show up at all in the adaptec storage manager and the raid still shows as degraded

    There doesnt appear to be a way to add new disks to the raid through the storage manager.

    Has anyone else ever used this card and managed to successfully add a new disk to an array?

    Any help much appreciated

    You could try reading this article... but it's more than likely related to the replacement HDD you have used.

    IIRC you can force it to re-detect the drives by using Ctrl-A - this may also help.

    Finally - this article may also prove useful.

    Hope this helps :)

    Cheers for the reply, i had a quick look at those articles, one is slightly irrelevant as it shows a fix for if the card doesnt show at all

    The issue i have is that the card appears to be working fine except for the fact that it only shows one physical hard disk drive in the adaptec manager in windows, where as in the bios its showing 2 (which is correct as there are 2 physical hard disks)

    are the drives exactly identical ?

    when manufacturers change the hard disks, i.e. when they refine the manufacturing process or when the company gets bought out like seagate maxtor the drives change and it screws up the RAID arrays

    the hard disks are different makes and different sizes (one being 160 the other being 80)

    however, this is how it was originally set up, the 160 just utilises 80gb, the rest of the hard disk is unpartitioned.

    basically everything is the same as before except for the new hard disk, both disks are sata2
