The default blocksize in dd is 512 -- that is, ibs=512 and obs=512. If you only specify obs, ibs still remains at 512. 2048 / 512 = 4. 107 * 4 == 428, which is about 425; chances are the file isn't *exactly* on a 2047-byte boundary, which explains the "missing 3". If you do "bs=2k", you should see both 107 records in and out. I hope this helps clear up any concern over that part. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
