I'm not sure since it gave me two different outputs: one with an error at the top and one without. I'd take a guess and say it didn't because between the two there's only an extra 0.1 seconds and no extra data, but I'm not sure if it did or not. /dev/Storage/Storage is a 1 TB disk (terabyte = 1012 = 10004) or 931.51 GiB (gibibyte = 230 = 10243) or 1953513472 sectors. The filesystem on the disk is messed up and doesn't work properly. $ sudo dd if=/dev/Storage/Storage | pv | dd of=Storage.img dd: error reading ‘/dev/Storage/Storage’: Input/output error ] 1627672400+0 records ins] [ <=> ] 1627672400+0 records out 833368268800 bytes (833 GB) copied, 75181 s, 11.1 MB/s 776GB 20:53:01 [10.6MB/s] [ <=> ] 1627672400+0 records in 1627672400+0 records out 833368268800 bytes (833 GB) copied, 75181.1 s, 11.1 MB/s linux dd share|improve this question edited Apr 27 at 15:26 Anthon 47.4k1462125 asked Aug 16 '15 at 0:08 Scoopta 167114 (1) Please show the command(s) that you typed to get this output.
