Diskpart Failed Extending Basic Disk

[Guest]

Hello,

I have a SAN attached Basic Disk setup, that we tried to Extend. After
using DiskPart the partition appears to have expanded from ~50 GB to ~70GB.
However, the volume size in Disk Management as well as the disk in Windows
still only show the ~50 GB that the disk started out with. Querying the
volume with diskpart will show the correct 70 GB amount.

I did a little looking around with DSKPROBE and in the NTFS BootSector I see
that the total sectors is set to 104840126. Doing a little math I figured
that 104840126 Sectors * 512 bytes per sector = 53,678,144,512 total bytes or
about the size that the disk started out as. Does anyone know if this is
what is causing my volume to display the incorrect size? Do I need to update
the total number of sectors in order to be able to use the rest of my volume?
Or is there some other tool that could assist me with this problem.

Thanks,
Tad Smith

It appears that i need the FSEXTEND tool from Microsoft. Is this tool
publically available at all? I'd rather not waste $250 calling Microsoft for
a tool that should be freely available.

Hi Everybody

In case anybody else encounters this problem:

The diskpart utility has an undocumented option called "extend filesystem"

if your disk manager shows a bigger size than your disk properties, use this by first calling diskpart, then "select volume #" and then "extend filesystem".

This should take care of your problem. At least it did for me.
