"dd" is not a special tool for accessing device files. It's a simple file copy tool: like "cat" or "cp" but with different options. "dd's" internal buffers can be changed with ibs= and obs= but those have nothing to do with block device sector size. (Imagine that "cat" had input buffer size option --ibs= which sets how many bytes it reads and stores from input file or standard input stream at one time. The tool could also have --obs= option for setting how many bytes it writes to the standard output at one time before filling the output buffer again. That's what "dd's" ibs= and obs= do.) -- /// Teemu Likonen - .-.. https://www.iki.fi/tlikonen/ // OpenPGP: 6965F03973F0D4CA22B9410F0F2CAE0E07608462
