A few bad sectors failed to boot
the operating system smoothly
when doctoring the optimizing process on the disk,
sector by sector
cluster by cluster

it's running but not too well as before
several files could not run properly,
might be corrupt
or missing a few chains,
garbage data have shown

yet could not backed up the entire files successfully
even the several programs also
when running the machine abnormally
the old hard drive is sounding a little,
seeming to crush the physical memory anytime

There is only an operational way
to rescue the hard drive by the low level format
which 'll erase all the random memories
those bad clusters will be fixed permanently,
though yet a chance of fatal error
