    Hi all,


  I'm trying to use dd to dump stuff to a usb flash drive (i.e. mass storage
device).  However something tricks it into thinking the device is full
(/dev/sdb is the pendrive):


dk AT CHILLI ~
$ dd if=/tmp/msd-test-data.cXoEqa2332 of=/dev/sdb bs=100 count=1
dd: writing `/dev/sdb': No space left on device
1+0 records in
0+0 records out

dk AT CHILLI ~
$


  Reading from it is no problem:


dk AT CHILLI ~
$ dd if=/dev/sdb bs=100 count=1 | od -c
1+0 records in
1+0 records out
0000000 353   < 220   M   S   D   O   S   5   .   0  \0 002 001 006  \0

0000120   8   N   $   }   $ 213 301 231 350   < 001   r 034 203 353   :
0000140   f 241 034   |
0000144

Is this expected behaviour under cygwin?  What does "no space left on device"
even mean for a raw disk volume as opposed to a logical volume / partition?


    cheers,
