Re: [Bug-ddrescue] Handling drives that have broken partition table?

[Paul Daniels]

Sorry, I should have been more specific about the particular situation 
that arises.

When sector-0/partition-table is physically damaged and non-recoverable 
it sometimes causes the drive to "offline" itself when you try to read 
it, as such you can never recover these drives with ddrescue+linux 
because linux will attempt to read that partition table each time you 
power the drive up.

What would be nice is if there was an overlay facility/magic in linux 
where, if you already had a copy of the data in that area (or even just 
fake), you could make linux read the partition/data from the image/clone 
and switch to the real drive for other areas.

Hope that clears matters up.
