how much of an impact will that have on resources; "for every
block read or write check if it requires LBA48," sounds kinda
just reading on badsect, neat program. while it is not 100% the
right solution, because it's a firmware issue not a 'bad block' --
it seems like a good and simple fix because, effectively, the block
that said. what a PITA to make a BAD directory each time a seagate
disk is deployed. instead of processing drive specific quirks at
runtime, why not make a one time quirk for newfs (or disklabel or
fdisk...) to reserve that seagate block from future use?
also I notice, there is no problem with adjacent blocks. but the
solutions discussed refer to sectors, are they synonymous?
