"OverflowError: long int too large to convert to int" while parsing scan results

[KDec]

Background info:

1. Disk: Seagate, Capacity 4T, one primary partition, NTFS file system in the partition. Windows Explorer shows no files in the file system, checking the drive capacity in Windows 10 shows that 80% of the drive is in use. The latter is true as I used the drive to store all my backups.
2. I use Knoppix distribution (V7.6, 64bit), which I boot from a DVD Drive.
3. Recuperabit was able to scan the complete 4T HDD (9 hours) and then successfully wrote the save file (16MB in size).
4. Processing went ok but then ran into an error with the following message:

Traceback (most recent call last):

OverflowError: long int too large to convert to int

Is there any way to change the environment to avoid the OverflowError? Fyi, I run main.py directly from the shell command line in the Knoppix terminal window, no pypy .

Thanks in advance for your support - would be great if there is a fix to this problem.

OverflowError: long int too large to convert to int

OverflowError: long int too large to convert to int

This is due to a line that was forgotten when #1 was fixed.

Tested the fix successfully. Scan results are now parsed successfully.
