(oops, just noticed that part) . If this is really on the swap area of the disk (verify that by looking at the partition info and seeing where that block is) then this is easy to fix: 1. Verify that AWRE is enabled in mode page 1; 2. Disable swap on that partition; 3. dd from /dev/zero to that partition. The write will force the sector to remap; 4. Tell -hackers that swap is being read before written (that doesn't make much sense). -- Peter Dufault Real-Time Machine Control and Simulation HD Associates, Inc.
