Yes, but obviously they are not shown if you filter the ls output
as above. A plain `ls' should show them.

This has nothing at all to do with it. But the above output from
/proc/partitions is strange. Where's sdb1? Anyway, typically you read
from sdb1 on CF cards and their siblings. Only as admin you can read
from sdb. I just tested this again with a CF card in an USB reader
attached to a W7 64 bit machine running Cygwin 1.7.17. Are you *sure*
you tried it with admin rights? Did you start your Cygwin shell with
`Run as administrator'?
