How to reinitialize a disk, which is not accepted for the storage pool RRS feed

  • How to reinitialize a disk, which is not accepted for the storage pool 

    Sometimes you may experience one of following symptoms, if you try to add or readd a hard disk, which is currently not part of the Windows Home Server storage pool:
    • the disk is not listed in the console
    • the disk is listed in the console, but cannot be added to the storage pool or as server backup disk
    In both situations the disk is present for the operating system, if you check the Disk Management Console. To do this, perform following steps:
    • Login to the Windows Home Server desktop locally or via Remote Desktop client.
    • Click Start/Run, type diskmgmt.msc and click OK.
    Your new disk should be visible in the lower area of the Disk Management Console.
    (If the disk is not listed here, it is either not properly connected, physically broken or you need to add drivers for the mass storage controller, to which the disk is attached.)

    In some cases such disks could be detected and added successfully via console after recreating the Master Boot Record (MBR) and deleting old volumes on it.
    (You should not try this with a disk, which has known bad sectors.)
    To do this, attach the disk to a system (can be a client PC or Windows Home Server), open a command prompt and enter following commands:
    list disk
    Check the output of this command carefully and try to figure out, which disk is the disk, which could not be added. If you are not sure (this can happen especially on a server with multiple disks), you may wish to perform this action on a client PC with only one normal disk to avoid an erratic identification.
    select disk x
    Replace the x with the number of the volume, which represents the disk you wish to reinitialize.
    Stop here, if you are not fully sure, since the next command will wipe all data from that disk!

    Try now again to add the disk to the Storage Pool or as Server Backup Disk.

    Remark: If you want to give away a disk, which had private stuff on it before, you can use clean all instead of clean in the described sequence to wipe all sectors on the disk, making an unwanted data recovery a very hard job for the new owner.
