For Linux e2fs partitions, the command 'mke2fs' is used to format the
partition and optionally set the block size using the -b block-size
option. The block size for e2fs is basically the equivalent to the FAT
file system's cluster size. The default is 1024 bytes, at least for the
partition sizes I use. See man mke2fs or man mkfs.ext2
You can use a utility like dumpe2fs (from the e2fsprogs package) to dump
information about the e2fs file system on any particular partition into
a text file like this...
dumpe2fs /dev/hda1 > hda1.txt
...and view it in a text editor. It will display much information
including the block size. See man dumpe2fs
