Exactly, I've had this problem with several drives where I get a bad sector somewhere, often underneath swap, a journal, or some other file system bit, because that's what's being dealt with before the incident that caused it.
Drives often don't remap UNTIL YOU DO A WRITE. So I keep getting errors while trying to mount, fsck, or when doing something to an adjacent sector, until I manually zero out that sector. Then my hard drive is perfect again from the OS's viewpoint.
Of course using bad block lists can often not do the right thing, because they only do a read test...
