If you are sure (really sure!) then the disk in the command must match:

cat /dev/zero | pv -s 3000G | dd of=/dev/sdb bs=100M

Unless you have write-intent bitmaps enabled, then just removing and re-adding a drive will cause MD to overwrite the entire disk, including your pending-bad blocks. Thiis has worked for me many times. Remember, though, that the SMART Offline_Uncorrectable won't get updated until the next offline collection occours, like with smartctl -t offline. </comment>
