How to copy a full "alien" HD to another

[destroyedlolo]

Hello,

Is it a way under Gentoo to copy an PATA disk to another ? (like dd or such).

Problems are :

• it's an Amiga disk, and I'm not sure that the partitioning information is compatible w/ PC world
  
• disk are not sharing the same geometries : Mechanical 52Mb -> SSD 128 Mb (I will extend last partition from Amiga world.
  
• Target disk has to be bootable (so it's why I'm looking for a low level copy).
  

Thanks

Laurent

ps : after 17 year being sleeping in my atic, I woke up my wonderful Amiga4000/040 ... and the magic is back

Thanks Neddy,

But is it able to do the partitioning ?

And this option is only for the FS, does it means it is enough to understand the paritioning ?

destroyedlolo,

The first option allows the kernel to understand the partition table.

The second option may allow it to read/write the filesystem.
Is it an AFFS filesystem?

If you can mount the filesystems, then all the usual commands will work.
dd will always work as it copies disk blocks without regard to content. Use bs=1M, to get the speed up

I know nothing of permissions on AFFS filesystems, so linux tools, other than dd, may not preserve them.

Thanks, I'll have a try

For the permission, it's RWX like on unix + some extended ("Pure" for example to load and stay an executable in memory). There is even the room for Group and Other even if not used out of the box (will be used when adding networking).
