Answer by Matija Nalis for Can't mount FAT32 drive under Ubuntu Linux

For me, fsck.vfat /dev/sdd1 returning "Logical sector size is zero." was because it was not vfat, but rather newer exfat. So I had to install tools appropriate tools (apt-get install exfat-utils exfat-fuse) to be able to mount and fsck it (by using fsck.exfat /dev/sdd1 instead, or even better just fsck /dev/sdd1 and have fsck autodetect the filesystem)
