You might find cp(1) works where cat does not.
I read about that. However, some mpeg(video) and ISO (cd image) files have the same problem. cp doesn't work either on these files.

Maybe ova file was not a good example.

Another example as root:

# dd if=winxp1.8.ova of=/dev/null
dd: winxp1.8.ova: Invalid argument
4194303+0 records in
4194303+0 records out
2147483136 bytes transferred in 116.564 secs (18423057 bytes/sec)

Diagnostic tips (hints) are also welcome.

Update: Ok, bit dumb to use an ova-file example again. But other files had the same problem anyway.
