But for a sane system you *should* be able to take the dd image and put it
back on a larger capacity drive in the Amiga, and everything should just work.
1) Any hardware that supports some kind of "put this x blocks from the *end*
of the disk" is obviously going to fail, because the end of the disk won't be
where it used to be. I don't know of anything nuts enough to actually do this :)
2) If partition table settings are specified in terms of cyls/heads/sectors,
rather than block lengths / offsets from the start of the drive, you're likely
going to have problems. No idea how Amiga disk ystems work, so I don't know if
it's an issue or not.
Presumably the partition table / filesystem format is well-documented though,
so even if (2) is a problem, you could chop a raw dd archive of the failing
disk up into chunks of partition data, and write those out along with an
appropriate revised partition table to the 'new' disk.

Ahh, no spare drives here then. Generally, I don't 'do' IDE. Took me well over
a year to find a replacement IDE disk for my RiscPC (that was around 2.5GB too)
