Otherwise holes in source dropped by bad sectors photoshop elements 9 mac trial will be joined by sector shifting on destination.
There is no magic in dd, the magic is all in /dev/sdb.3) checking my original disk I saw the following: Code: sudo fdisk -l Disk /dev/sda: 1000.2 GB, bytes 255 heads, 63 sectors/track, 121601 cylinders, total sectors Units sectors of bytes Sector size (logical/physical game juiced 2 for pc rip 512 bytes / 4096 bytes I/O size (minimum/optimal 4096 bytes / 4096.First steps, the first thing you need to do is boot into your live distribution.As with the copying process, this must be done while booted into a live distribution.Make sure to know the location and names of both your source and your target.There is quite a lot more that dd can.If youd prefer to see the status of the command as it works, you can include the statusprogress argument like so: sudo dd if/dev/sda of/dev/sdb1 bs64K convnoerror, sync statusprogress.Originally Posted by sudodus If source and destination are mass storage devices like sda and sdb in it should work.All important sectors were saved, so the cloned disk worked (and works) well.

I saw many posts dealing with this issue, yet most of them, if I understood correctly, had to do with the fact that, in most cases, both disks were used simultaneously and usually some partitions were cloned, not the entire disk.
Use a log file and run it twice, if bad sectors are found.To that end, you must use caution when working with this tool.Attention, when you'll make a mistake, you will lost all your data.The dd command will copy both used and unused space from the target.You can do this also with ntfs windows partition and hard drive used by this.Disk identifier: 0x000f1d1e Device Boot Start End Blocks Id System /dev/sda Linux /dev/sda Extended /dev/sda Linux swap / Solaris next let's try bigger than 512 divider, we have physical sectors: /, very good, we can do bulk copy of 256 sectors.2) even if there is a bad sector in one of the disks (both were brand new disks is it normal that I see the info unallocated to the cloned disk?If it is possible, you can boot or change system level into 1, for single user mode, or you can directly reboot system into single user mode, it is distro depended.If you want a progress report, since you're using Linux, you can easily get one by noting the PID of the cat process (say 1234) and looking at the position of its input (or output) file descriptor.Open terminal or shell prompt and type the following dd command: # dd if/dev/sda of/dev/sdb, where, if/dev/sda : Input disk (source) of/dev/sdb : Output disk (destination you can also copy hard disk or partition image to another system using a network and netcat (nc) command.
