Details
Image backups with 10.3.0 thru 10.3.2 releases may fail in some rare cases with the message "DISK Failed to estimate volume"  The message "Failed to build volume bitmaps. Error 14" may also be seen.  
Upgrading to Appliance release and Agent release 10.3.3+ resolves this issue.  
In some cases, disk extend size will not match disk reported size.  This is common in cases where NTFS volumes were expanded, or are using sizes not divisible by 4GB.  Code was detecting these differences as an error, we have now unified code to always use the same method for NTFS to avoid conflict.
