Description

Dumping large hard disks to Aaru format results in a "System.OverflowException: The input exceeds data types" at SpamSumContext.cs:119 upon nearly completing hashing the image file. I encountered this with a 2TB drive.

This is probably related to #722 and #649, however since this throws a different exception with a different drive than #722, and at a different point in the dumping process than #649, I filed this as a separate issue.

As in #722, the dropdown in the bug report form only lets me select 5.3.0 as the latest LTS version, however I was also able to reproduce this in 5.3.1, both release and debug builds.

Exact command line used

./aaru media dump -O compress=False,deduplicate=False -v -d /dev/sdb /mnt/NACM2YNL.aaruf 2>&1 | tee output.txt

Expected behavior

Hashing the image file should complete without error, proceeding to hash sectors and finally close the image.

Actual behavior

Hashing image file byte 221757046784 of 221757282061
Unhandled exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

Using the command line provided, I generated a full log from a debug build, however owing to its large size (11GB), I bzip2 compressed it and am hosting it here on Dropbox:

Very interesting, it is a different error but it seems to happen in the same line of code as #722. Same general advice to workaround this issue should apply, thank you for being so diligent and noticing that the errors were different!
