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 0000020 002 \0 002 @ \0 370 001 \0 001 \0 001 \0 \0 \0 \0 \0 0000040 \0 \0 \0 \0 \0 \0 ) { 6 354 024 N O N A 0000060 M E F A T 1 2 3 311 0000100 216 321 274 360 { 216 331 270 \0 216 300 374 275 \0 | 0000120 8 N $ } $ 213 301 231 350 < 001 r 034 203 353 : 0000140 f 241 034 | 0000144 dk AT CHILLI ~ $ 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, DaveK -- Can't think of a witty .sigline today.... -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
