Drive size reallocation software RRS feed

  • Question

  • I have a Windows 2011 server SP1 with latest updates.  The main drive '0' is 1TB which is divided into C: 60GB and D: 940GB more or less.

    Needless to say the C stuff is slowly getting bigger but the drive is not.  Can someone recommend a software to resize the C drive using the D drive space.  The D drive is almost empty.

    Now what I did so far is shrink the D volume but that of course did not help because the new free portion is on the wrong side, not contiguous with the C portion.  Now in concept I can most likely make a new drive out of the new free portion, move the stuff from the D to the (new drive letter), and then delete the old D volume.  Once this is done the free space will be next to the C drive and allow me to expand the C drive.  All sounds ugly and error prone so if there is something that can handle it for me for a small price I would be happy to pay that.

  • Hmm, that's not how it works! There is no reason why your C: drive should be growing. Do you have any shared folders on that drive? If so, use the Dashboard to move them to D:.

  • I use my server for things other than file storage.  I don't keep files there but programs seem to be getting bigger all the time and all the different versions of .NET... well it is getting smaller.  Very slowly but smaller!

  • You can search ZDNET Downloads for Windows utilities like this. But I don't think there is a way to increase the partition size.

  • Yes ZDNET has several and I have found several others but was hoping for recommendations since I for one don't trust ZDNET download much. I have gotten to much crap from them. It also adds a level of search difficulty that is has to be for a server and not a PC.

    So far the below link seems the most reasonable but for a one time solution in my case it seems expensive at $139/$229.  If a person managed servers or such it seems like a reasonable price, just not reasonable for one time use.  Oh well I guess I will have to do it the hard way.

  • How about this one: http://www.easeus.com/partition-manager/

    It's free. Used it when Disk Management couldn't do what was needed and it worked great.

    Just beware, if you use this on a client that is being backed-up by the server, you might want to check whether the backup schedule of the client still includes the appropriate partitions.

  • Thanks but I don't think the free version works on a server.  You have to get Partition Master
    for 159 if you want to use it on a server.

  • I used a partition manager program to extend my C drive, and when I rebooted it crashed and I had to reinstall from scratch.  I'm wondering if there is something in WHS that only works with a 60GB partition.

  • Hi,

    in the dashboard you could move all shared folders and backups from drive D: (which should be the data volume on the system disk) to a second physical disk, if your server has one. Or back up the content, delete it and move these now empty shares temporary to C: drive through dashboard.

    After that is completed and you made sure, that there is no other relevant stuff on that volume, you can delete the D: volume through disk management console or diskpart, increase the size from an administrative command prompt on the server desktop with diskpart size=x after selecting the C: volume (replace x with the size in MByte, which you want to attach to the C: volume) and recreate D: afterwards with the reduced free space.


    select volume c:
    extend size = 140000

    would add 140 GB from free (unpartitioned) diskspace located directly behind volume C: on a basic disk

    With 3rd party software like Acronis Disk Director o the mentioned freeware you would eventually be able to perform the task directly without emptying the data volume even on a server, if you boot the server from Acronis recovery media or Windows to Go.

    But like with all serious disk operations, you should have a current backup of all the important stuff - not that a crash or power outage brings down your server during the process and you remain with nothing.

    Best greetings from Germany

  • Ah, I see. It would not surprise me if it would work on WHS2011 anyway but otherwise you *could* take out the disk, install it in another PC running, say, W7, do the work and re-insert into the Server. I have done this with OS-drives using USB adapters.

    Otherwise, the suggestion of cleaning out (by moving or backup/restore) of the D partition and using diskpart (although I would try Computer Management -> Storage -> Disk Management) should work as well.

    A few further thoughts, having a backup before proceeding, through whatever route, would be my choice (but then, I already backup the Server). Also, IMHO, Phil is correct when he says the C:\ drive should not fill up.
