Hello Karl,

I will do my best to resolve the issue you experience.

It’s preferably to write your request in English because most of all the forum community is English-speaking and your thread may stay unanswered.

There are several possible reasons for the issue. Generally such problems are related to malfunction of SnapAPI module. I would recommend you to update SnapAPI drivers using the following KB article.

The possible reason can also be file system errors or bad blocks on the hard drive. So if SnapAPI update didn’t help you check the disks for errors:

  • Go to the Command Prompt (Start -> Run -> cmd);
  • Enter the command:

chkdsk DISK: /r

Where DISK is the partition letter you need to check. Please note, that checking the C: drive may require you to reboot the machine.

If the issue still persists open a new support case using this link and submit the following diagnostic information:

(1)

Could you please download Acronis Report utility available at http://download.acronis.com/support/AcronisReport.exe and run it, create a report and send it to us? Please compress the Acronis Report output file into an archive (e.g. with WinZip) and attach to your message by browsing for the archive. This would provide us with detailed information on the hard disk partition structure.

(2)

Please also attach device tree to help me identify the possible program which can lead to Acronis software malfunction.

Could you please do the following?

- Download and unpack the Device Tree application:

http://download.acronis.com/support/devicetree_Vista.zip

- Run the application from "i386" folder (run the 64-bit version of Device tree from "x64" folder if you have Windows Vista 64-bit);

- Completely unfold (click on all plus signs) the \Driver\partmgr and \Driver\volmgr branches;

- Move the margin to the right in order to see all the items;

- Make a screen shot and send it to us.

I noticed you are not using the latest build.  You may want to update the build, I am not certain if the issue is addressed in the new build at this point, however it is generally a good idea to be up to date. You can download the latest build from your account under registered products.

Let me know the results as soon as possible.

Thank you.
