Hi,

Yesterday, sadly, whilst using RiscBSD something happened which seems to 
have stopped me from booting RiscBSD.  I am not sure what caused the 
problem, but need to recover a few files from the disc which I need for 
the end of next week.

As far as I can see, all that is wrong is that the Superblock has got 
done in.  When I boot, it complains that it can't mount root on /.  I 
tried booting with the install floppy and running fsck on the disc - it 
says that the SuperBlock has a bad magic, and then asks whether I want to 
look for backup SuperBlocks.  If I type 'y', it seems to give up rather 
too quickly (doesn't even access the disc by the sounds of it) and says 
it can't find any.

Is the version of fsck on the install floppy a full version?  Or is it so 
cut down that actually it doesn't know how to find a backup SuperBlock?

Given the geometry of the disc, could calculate where a backup SuperBlock 
will be, and then tell it using the -B option - and even then, would it 
know how to recover it?

Could someone send me a full version of fsck from the release sets, or 
put one of an FTP site for me to get?  Would this even help?

Could it be something else is wrong, such as the bootblock?

The system is a RiscPC600 with 24Mb DRAM, 2Mb VRAM, 1Gb SCSI Drive on 
Cumana Card of which 600Mb is RiscBSD, and a 400Mb IDE drive.

Thanks for any help you can give -

Ben.
