Solved itself. For completeness I attached a screenshot of the block log from yesterday. But today this did not happen anymore.

It detects Trojan:Script/Wacatac.B!ml. Best regards, Micha

Is this information actually still true? Debian GRUB supports secure boot without any non-free packages. Since this was the major reason to have the alternative Clonezilla Live, I am hence wondering whether it can be dropped altogether.

We had a hard time investigating the following error: # sgdisk -e image.img ... Warning! Secondary partition table overlaps the last partition by 2014 blocks! Try reducing the partition table size by 8056 entries. (Use the 's' item on the experts' menu.) Aborting write of new partition table. The image is sized to cover the end of the last partition + 34 sectors for the backup GPT, which contains the default 128 entries and hence has the default size of 32 sectors + header. The overlap of 2014 blocks...

mkfs.fat: https://manpages.debian.org/mkfs.fat With -s option you can define the cluster size as a multiple of the sector size. But default, however, it uses 1 sector per cluster for such rather small boot partitions.

That is great, many thanks. I'll keep creating images with a valid number of clusters, but it's good to be able to browse them regardless.

Ah sorry it is actually all good. I recognised just now that the number of clusters in the affected FAT filesystems was actually some hundreds lower than expected. Looks like the remaining space is used for metadata. While Windows and Linux have no issues to access the filesystem and also fsck does not return an error, it does return a warning about the number of clusters and that "some systems might have issues with this". After reducing the cluster size to 1024, 7-Zip can perfectly access it. However,...

I love 7-Zip for being able to open and browse raw disk image files with partition tables and partitions with support for many Linux filesystem types, a feature which native Windows itself surprisingly keeps lacking. However, I recognised that 7-Zip cannot open FAT32 filesystems with non-default cluster size. By default, when creating a FAT32 filesystem on Linux, it has 1 sector for 1 cluster, usually 512 bytes. This is not always optimal, also Windows uses larger cluster sizes by default, depending...
