From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11) Gecko/20021120 Netscape/7.01 Description of problem: also wrong in RHE 4 package raw(8)'s BUGS section says: The Linux dd (1) command does not currently align its buffers cor- rectly, and so cannot be used on raw devices. coreutils-4.5.3/src/dd.c says: The page alignment is necessary on any linux system that supports either the SGI raw I/O patch or Steven Tweedies raw I/O patch. It is necessary when accessing raw (i.e. character special) disk devices on Unixware or other SVR4-derived system. */ real_buf = xmalloc (input_blocksize + 2 * SWAB_ALIGN_OFFSET + 2 * page_size - 1); and dd Works for Me Version-Release number of selected component (if applicable): util-linux-2.11y-31.11 How reproducible: Always Steps to Reproduce: 1. man 8 raw 2. 3.
