| 19:28 | < Yossarian> | So I'm taking a look at my old hard disks. First up is 64GB SSD. It has NTFS boot partition and NTFS main partition... I think I want to clone the boot partition in case I want to check out the contents of the .img in a virtual machine. |
| 19:33 | < Yossarian> | to use `dd` to backup the entire disk (/dev/sdf - in this case) does block size matter? |
| 19:36 | <@Tamber> | I usually use something like bs=1M (or more like 8M) because istr it speeds it up because it's moving as much as it can per transfer? (even if not necessarily the full 1M/8M) |
| 19:48 | < Yossarian> | if I clone the entire disk including the boot partition and my bs size isn't a multiple of the boot partition... can that possibly exlcude some of the data? |
| 19:49 | <&[R]> | No |
| 19:49 | < Yossarian> | source disk (/dev/sdf) is a solid state drive, so... no CHS or internal CHS via LBA |
| 19:49 | <&[R]> | It's solely an efficiency thing |
| 19:50 | <&[R]> | You don't even need to use dd |
| 19:50 | <&[R]> | You can use cat or pv |
| 19:50 | | * [R] ends up using pv|ssh occasionally |
| 19:50 | < Yossarian> | the larger you increase bs, higher possibility you run into copying a bad piece of data from if? |
| 19:51 | <&[R]> | That's not a factor in the possibility of getting bad data |
| 19:51 | < Yossarian> | or not quite? |
| 19:51 | < Yossarian> | later on, I'm gonna see if I can boot the .img inside qemu |
| 19:52 | < Yossarian> | 1<&[R]> You can use cat or pv * [R] ends up using pv|ssh occasionally |
| 19:52 | < Yossarian> | How's that? |
| 19:52 | <&[R]> | pv /dev/sdf | ssh HOST cat \> sdf.img |
| 19:52 | <&[R]> | Or |
| 19:53 | <&[R]> | ssh HOST cat \> sdf.img < sdf.img (note which < and > is escaped and which isn't) |

| 19:54 | < Yossarian> | pv? had to install it real quick, interesting tool: ` pv -EE /dev/sdf > disk-image.img ` |
| 19:56 | < Yossarian> | very interesting multi-tool |

| 20:09 | < Yossarian> | [R]: It seems like Intel 8 Series C220 SATA Controller in AHCI mode (rev 5) is hot swappable. |
| 20:12 | <&[R]> | Neat |
| 21:02 | < Yossarian> | [R]: some reason the partition table is messed up, might have been that way without my intervention... it's an older SSD |
| 21:04 | < Yossarian> | Is there a specific command line option for qemu to enable KVM or is it done by default? |
| 21:04 | < Yossarian> | processor has VT-x support |

| 22:02 | <&[R]> | -enable-kvm or -kvm, depends on the version |
