For the weekly backup, I am now getting this error:<br><br>[2388063.441067] sd 13:0:0:0: [sdb] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE,SUGGEST_OK<br>[2388063.441073] sd 13:0:0:0: [sdb] Sense Key : Medium Error [current] <br>

If I replace the disk with an identical brand (but has a different make<br>of disk inside), I get other errors.<br><br>These two disks have been stable and trouble free for about 2 years,<br>with no issues.<br><br>My questions are:<br>
<br>1. Short of dd if=/dev/sdb, is there a way to detect blocks?<br>
<br>2. Do we have a way to add the bad blocks to a list that the operating system<br>should ignore, like we had in the old days?<br><br>3. Could this be a quirk of some sort? How do I know for sure if it is <br>really a media problem or some bug/quirk?<br>
