Re: Using the md driver to look at a bad hardware RAID.

So my dead drive has died further and will now read() nothing. 
It is an ex drive. Unable to do any manual XOR sanity checking, 
I can only read out the remaining drives, and pray that in the scratch 
space where they get copied to, I can find a partition that will 
make sense to the debugfs utility. 

Here's the C program I wrote to that end. Read the source
and make it suck less before you try to use it.
