I think that would depend on the drive itself? I can't say I've tested it. 
I'm still using the original drive in my 630, and I have that kernel 
option disabled.

Hmm. Is the block number the same when you reboot? If you wanted to, 
debugfs will let you figure out what file or directory is using that 
(logical) block. I suspect you could then generate an I/O to reproduce the 
error at will.

It seems the bad block (if that is what it is) is at the end of the disk. 
Maybe try
# find X -xdev -false
where X is the hda12 mount point.

Sorry, I can't say I've tested that mode either. But thanks for posting 
your results.
