Problems with reading hidden volume header

[CharlyIO]

Hi,

I use TCBrute 2.7.4126.37970 on a hidden volume, but the application stops telling me following:

 >> Prepare new crack Operation...
 >> Configuration seems valid.
 >> Analyzing Wordlist...
 >> Wordlist anaysis: 24310 Passwords!
 >> Extracting Volume header...
 >> Can't read Volume Header \\.\Z::
Offset und Länge für das Array liegen außerhalb des gültigen Bereichs, oder die Anzahl ist größer als die Anzahl der Elemente vom Index bis zum Ende der Quellauflistung.```
(Offset and length were out of bounds for the array or count is greater than the number of elements from index to the end of the source collection.)

The volume is an external usb-harddisk with ~ 1 TB. I suppose, that the size is responsible for this error?

My Job-Config is:

    <?xml version="1.0"?>
    <CrackConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
      <WordListPath>C:\Users\CharlyIO\Desktop\wordlist.txt</WordListPath>
      <WordListOffset>0</WordListOffset>
      <ContainerPath>\\.\Z:</ContainerPath>
      <MountAsSystemVolume>false</MountAsSystemVolume>
      <AttackHiddenVolume>true</AttackHiddenVolume>
      <UseKeyFiles>false</UseKeyFiles>
      <KeyFiles />
      <ThreadCount>2</ThreadCount>
    </CrackConfiguration>

Any ideas how to solve this? :)
Thanks!
