Disk Management Combining Partitions In The Same Or Non Same Hard

    Disk Management Combining Partitions In The Same Or Non Same Hard

    On SB 2003 Server

    In Disk Management Under Computer Management; Have a few hard drives listed
    & they are partitioned as Main OS Root & the others as different data drives.
    Set this up upon initial SBS Setup.

    My question; is it possible to take two of these partitions (On same Data
    HD/non-OS,) & combine them? (Or partitions from different HDs for that
    matter?) My guess would be on same HD I have to delete the partitions first,
    but I wanted to make certain. Possibly Seeing Them as “Non-Partitioned
    Space”, combine & then format them!

    Any insight offered would be appreciated Jim B

    You can combine them (though I strongly urge you NOT to do so across
    physical drives), but only by deleting all but one and expanding it into the
    deleted space. The reason for not doing this across physical drives is that
    you're creating a scenario where the failure of either drive will cause data
    loss across the entire partition. This actually INCREASES your potential for
    data loss (if you create a single partition across two disks, you've
    increased your risk of data loss by 100%, assuming equal MTBFs on the two
    disks. If you spread across 3 disks, you've increased it by 200%, etc.)

    Re: Disk Management Combining Partitions In The Same Or Non Same H

    Yes Charles, you are very wise to proceed w-caution. Just to further expound,
    I have two (2) physical HDs partitioned into Four (4); --> A 500GB sectioned
    into 200GB for OS & Programs & 300Gb For All Data.

    The other is Separate & a 200GB Partitioned into two (2) equal sizes for
    additional data. This is the one I had planned to combine back into its’
    original size. All data is regularity backed to the main 300GB Partition
    along w-WD HDs. So I think I am safe to combine the external one… Once
    combine I plan to make this one a BU drv as well my website server......
    Thank You Jim B

    Charlie,

    Does a mount point act the same?
    Will it also loose all the data if either drive die?

    TIA
    Rich W.

    Not certain if I understand your question Rich & know your question is
    directed to Charlie,) However & to give back a little of what I have gotten
    from MS Discussions Groups, I have lost my SBS OS on my main root partition &
    had to reformat. Another partition off that same root drive contained my
    business data under NTFS file format. Consequently all my data was intact &
    ready to use once I reloaded the SBS OS & programs.. I have since started to
    initiate daily restore points while still backing externally. Partitioning
    is a great way to put your data in a different location on the HD & there is
    always a good chance of recouping when necessary.(unless if HD is physically
    damaged!) Jjb

    Jim,

    I'm not talking about partitioning a 2nd drive.
    I added a 2nd hard drive with a mount point on the C: drive.
    It looks like part of the C: drive

    Re: Disk Management Combining Partitions In The Same Or Non Same Hard

    Possibly, depending on how you've implemented it. The issue is the
    underlying disk structure which is dependent on both disks being there. This
    is why RAID0 is a really bad idea. However, if you simply increase your disk
    size by mounting a volume that is contained on another drive, without
    extending the partition across multiple drives, you don't increase your
    risk. However, that being said, MS doesn't really do a very clean job of
    handling reparse points (which is what a mount is), so I generally don't
    recommend them.

    That scenario doesn't increase your risk (since the failure of either drive
    is independent of the other). But honestly, there are things that get wonky
    when they encounter mounted file systems. It's a feature that just doesn't
    work as it should, IMHO.
