I don't believe bad sector remapping (wih bad144) is supported anymore (with the newer ata framework). Newer ide drives (less that 3-4 years old) should have "perfect media" capabilities by default, where the drive will remap bad sectors on its own. The way you trigger that, if the drive is capable of doing it, is to use "dd" to read and write from the raw partiotion. I remember seeing commits to /etc/periodic/weekly in current that have a dd read the raw partitions in order to force the drive to preen itself. And yes, it looks like you'll need to backup that partition and either end the partion around that bad area or see if you can trigger the bad sector remapping. And before anyone rants about bad144 disapearing remember that you can buy 20 gig hard drives retail for about $100 US and most of the drive manufacturers let you RMA drives for a very long time after date of purchase.
