Summary: 4K FAT sectors don't seem to be supported.
Initial Comment:
>From Thai Duong (April 2009)
Recently I acquired a removable USB thumb drive containing one single FAT32 file system which most of the tools in The Sleuth Kit fail to analyze it. As far as I know, the reason is this FAT32 file system uses a 4096-bytes sector, while The Sleuth Kit assumps a sector to be 512 bytes. Is it that the case? Please correct me if I'm wrong.
Since each sector is 4096-byte, the 510 and 511 bytes of the first sector don't contain the signagure 0x55AA. This makes tools like icat or istat stop working. When I write the signature to these two bytes, everything is working again except fsstat who keeps complaining:
