Check if you have any partition without drive letter. In Windows Disk Management. Assign to it a drive letter and then remove it. After that try to take snapshot.

One of the solutions would be copying out data from D: and recreating it completely. It could be that Partition Wizard did not update registry information properly. Thus try to shrink this partition for 500MB using Windows Disk Management. Then remove and assign a drive letter to it again.
</div>


<div>
Thank you. for this I will need to wait for after hours. will update you
</div>


<div>
Just to clarify. <br />
1- shrink D partition <br />
2- create new partition on a allocated space <br />
3- to copy paste from D to E<br />
4- delete D volume <br />
5- create/format D partition <br />
6- copy paste back to D<br />
7- delete E <br />
8- resize D<br />
<br />
Please correct me if I got you incorrect.
</div>


<div>
Is copy and paste bast practice? Isn't it risk for error for example not coping hidden files etc.?
</div>


<div>
After #6 try to backup. Once you recreate the partition you do not need ro resize it. As long as you do these steps via Windows Disk Management - the issues caused by Partition Wizard should go.
</div>


<div>
You are comfortable using windows copy paste, correct?
</div>


<div>
Yes. Or you can use Robocopy. <br />
<br />
As far as I understand it, you do not have system files on D: drive, right? If the answer is - right, then copy paste should be OK.
</div>


<div>
When I exclude the D drive from the backup the backup also fails. Even so you are at the opinion the re formatting the D partition may solve the issue?
</div>


<div>
does it fail if you select just D for backup? If not, then formatting is not necessary. The problem then would be in one of your two partitions which goes not have a drive letter. Can you assing drive letters to them?
</div>


<div>
If I select only D it does not fail (although it still ruing for 30 minutes at the stage of reaching for modified &nbsp;files but it maybe for the first time it take this amount of time but in the even viewer I see the following error <br />
Volume Shadow Copy Service error: Unexpected error querying for the IVssWriterCallback interface. &nbsp;hr = 0x80070005, Access is denied.<br />
. This is often caused by incorrect security settings in either the writer or requestor process. <br />

You may find it helpful to point out again that after moving to partition all permission/share/ and share setting where lost.
</div>


<div>
Did so, this way I found that the system partition cusses the issue, but since it work before doing the partition move I opened a ticket with the backup vendor. <br />
<br />
PS I notified partitionwizard about the issue cussed by their software but got no respond. I would recommend using some of their competitor all are the same price
</div>


<div>
PartitionWizard is a chineese vendor as far as I know. There is a German tool Paragon Hard Disk Manager/Festplatten Manager 15 which does its job very good.
</div>


<div>
Thank you for this information, Ill know for next time.

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Small Business Server (SBS) is a line of server operating systems targeted at small businesses by bundling the operating system with a number of other Microsoft products that would normally need to be purchased or licensed separately. The most notable inclusions are Exchange, SQL Server, SharePoint and ISA/TMG (Microsoft's firewall and proxy server).

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Disaster Recovery is the planning for and creation of policies and procedures related to the resumption or continuation of an organization's functions following a catastrophic event. The term is most frequently used in relation to failure of networks, but DR preparations also include other business systems and personnel considerations.
