[smartmontools-support] disk not reallocating bad sectors

My thoughts were to create a pseudo-uncorrectable sector and then run an 
OS tool which scans the entire drive and forces the OS to update its bad 
block map. I'm not familiar with Linux file systems, but I know that 
NTFS has a $BADCLUS metafile. I believe this metafile would be updated 
by CHKDSK or ScanDisk if any sector/cluster fails the surface scan.

This method wouldn't reallocate a bad sector, but it would prevent the 
OS from using it. Or so I think ...
