Hardly. Some automat would have to have converted the file to a be
sparse one.

I would rather expect "short write" to be caused by the return value of
a write(2) call being less than the number of submitted bytes.
(It should not happen with a healthy disk device except at the very end
of its capacity.)

The disk address /dev/rdsk/c0t1d0s0 looks like Solaris. So it is no
wonder that i fail to find the dd message in Debian's coreutils.

Maybe it works better or fails with other diagnostic messages if you
use bs=512 and adjust or omit the count= argument.


Have a nice day :)
