I have an USB stick with 2KB hardware sector size. It worked nicely when
using fdisk instead of cfdisk which only supports 512 byte sectors. Dunno
remember exactly which filesystems I tried back then.
And first I wondered why it had a partition in the first quarter of it and
then empty space. I thought it might have been a fake 1 GB stick, but
still just deleted the partition and made it size the whole disk in
cfdisk - well at least I thought I did. The Linux kernel complained about
writing beyond end of device while mkfsing, I think it was an ext3.
