How long to make a VHD?

I started a conversion of a ghost image for a single drive of +/- 400 Gb.

 

After 90 minutes there was the beginning of a VHD file writen onto the destination. IT size was 966 Mb without nay change from the start of the conversion and when i took a look after 90 minutes.

Still  showed 0 % progress too ...

 

Is something happening or not ?

 

How long does it take to make a VHD ?
