I may get tarred & feathered for this, but oh well.
My job runs some Old-by-normal-standards UNIX systems with SCA disks
and we do dd copies of the OS disks fairly often.
I keep an Adaptec 2940<mumble> PCI card that supports SE and LVD
(don't go there; I know that if there's an SE device on the chain
they're all running SE. I Don't Care.) and a 4-connector LVD-rated
internal cable with an LVD-rated terminator on the end.
The PC it sits in is just something I dug out of the recycle bin and
runs Debian with a 2.6.something kernel. The "internal" cable hangs out
the back, as does an unused power bundle with 2 connectors available.
Plug in source and target disks, fire up the box, and dd away. (and
usually dd again to an image file on the host hard drive cuz I'm anal
that way.)
Not only does dd not care what the bus is, it doesn't care what OS is
on the media. The above is far, far from an optimal SCSI arrangements,
but it works error free and it works one HECK of a lot quicker than
doing the copies in situ.
Flame on, baby.

I don't really want an external drive. I
think I have some "normal"
enclosures, but for a copy I might be able to bodge something up just to
DD the disk...
