You're on 32bit, on 64bit this seems to work. My guess is that there is a limit to the block size available on 32bit (if that limit was 2G or just under it wouldn't surprise me), on 64bit there is a similar limit somewhere :
d...@major:~$ true | dd bs=3G count=1 0+0 records in 0+0 records out 0 bytes (0 B) copied, 2.1008e-05 s, 0.0 kB/s d...@major:~$ true | dd bs=3E count=1 dd: memory exhausted d...@major:~$ true | dd bs=3Z count=1 dd: invalid number `3Z' I can see an argument that there might want to put a better error message in, or state that the bs is dependent on memory size.
