| Dec 27, 2013 at 3:05 | comment | added | cybernard | lsscsi may also provide helpful information in identifying the correct source and destination designations. | |
| Dec 27, 2013 at 2:43 | comment | added | cybernard | Boot clonezilla english, whatever keymap you want, Enter shell,cmd You will get a prompt: Try to lsblk to identify the source and destination hard drive designations. It is critical you get the source and destination right. Change the sda and sdb below to match your system. There will be no going back and no further prompts until its done. Here is the command dd conv=noerror if=/dev/sda of=/dev/sdb bs=512 | |
| Dec 27, 2013 at 0:49 | comment | added | Ian Boyd | GParted fails to boot. It shows a graphical menu screen, then a console screen decompressing things, then a black screen that stays black for (at least) four minutes (at which point i hit the reset button). Clonezilla refuses to use the source disk (it's confused by an MBR partition on a dynamic disk). | |
| Dec 26, 2013 at 23:58 | comment | added | cybernard | Make a bootable cd of gparted. Shrink the partition size to it minimum and then clone it. You can even use gparted to copy the partition over. If that fails you can also try Clonezilla. | |

| Dec 26, 2013 at 19:12 | comment | added | Ian Boyd | It very well might be that this is an old, now discontinued, now unsupported, 64 GB Kingston drive. Or maybe it's just a bug in the drive's firmware where they forgot to implement sector remapping. | |
| Dec 26, 2013 at 19:07 | comment | added | cybernard | Actually an SSD has tons of spare sectors. In fact a 120gb ssd probably has up to 8gb of spare sectors. Why your drive didn't remap it automatically is unknown to me. Use gparted and shrink the partition. | |
| Dec 26, 2013 at 19:07 | comment | added | Ian Boyd | Katy Coe has an excellent blog that starts to delve into the guts of NTFS. But my eyes glazed over when i had to start calculating offsets, logical cluster numbers, virtual cluster numbers, and the fact that $BadClus is a spare file that is actually the size of the entire volume. i'd almost certainly destroy my (functioning) drive. | |

As an SSD, there are no spare sectors to remap into. That is why the drive's SMART continues to note a Pending Sector Count of zero, and a Reallocated Sector Count of zero.
