Hello folks.  This is probably a FAQ, but I couldn't find it in the 
mailing lists.  I have an IDE disk which is showing bad blocks i.e:

Jul  3 22:57:44 woody /netbsd: wd4a: uncorrectable data error reading fsbn 142987762 of 142987762-142987824 (wd4 bn 142987762; cn 141852 tn 15 sn 1), retrying

Since all of these block numbers are the same, I figured I could reassign
the block from the disk's spare sectors.  However, I know of no command to
do this with IDE disks.  Is there an equivalent of scsictl reassign <block
nnumber> for IDE disks?
