The dd ended as. I issued from time to time a kill -INFO to the dd to see its progress: # tail nohup.out ... 885016+0 records in 885016+0 records out 928006537216 bytes transferred in 35244.495687 secs (26330538 bytes/sec) 980612+0 records in 980612+0 records out 1028246208512 bytes transferred in 39028.251450 secs (26346202 bytes/sec) dd: /dev/da0: Input/output error 1154078+0 records in 1154077+0 records out 1210137444352 bytes transferred in 45969.382123 secs (26324858 bytes/sec) Does this mean I could use the first 1154077 blocks of 1m as partition, i.e. shrink it to this size and just ignore the rest? matthias -- Matthias Apitz, ✉ guru@unixarea.de, ⌂ http://www.unixarea.de/ ☎ +49-176-38902045
