Recovering a lost partition table

[Roger McCalman]

I have managed this.

By locating the super blocks of the filesystems and then
handcrafting the fdisk info I can now fsck and mount
all the file systems. Tomorrow I will attempt a re-boot on the
recovered file systems.

If anyone is interested in some C code to find super blocks - I have some.

Cheers, Roger
