Ahh, it's not worth the time & trouble incurred by having to nurse the upgrade
along unless you go as far as 3.5.2, where some tools have been expanded.
There's also a few new ones, but nothing necessary.

We've had several problems with this utility, not the least of which is the
fact that the block number is stored as an integer.  Imagine what happens
when you try to run 'fixbb' to exclude block #98062, for example.  Yep,
integer overflow, and subsequent exclusion of the wrong block (!).  Intel
shipped us a replacement which uses a long to store the block number (yep,
it's exactly two bytes larger than the original), and informed us that it
wasn't being officially shipped to anyone else.

Also, 'fixbb' only works on data blocks, so if your bad block is an inode
block or a cylinder group header, you're out of luck, unless

	o   you have a CRC error--we've had quite a bit of luck
	    writing a block of nulls atop these.  We usually try
	    this before using 'fixbb', because 'fixbb' makes the
	    block forever inaccessible, and necessitates an 'fsck'
	    to fix the DUP block left behind.

	o   you have some way to save/restore the rest of the track,
	    in which case you can re-format the track and put
	    everything else back.

So I followed up to comp.sys.intel . . .
