Right now the drive has just one reallocated sector. Your problem is the
157 sectors that are pending reallocation. Bad sectors cannot be
reallocated until the next time they are written. Simply writing zeros
to the whole drive will accomplish that. (For anyone who wonders why
a bad sector cannot be immediately reallocated, I suggest you think
about that for a while, specifically about what data will be returned
when that newly allocated, error-free sector is read. Remember, the
contents of the original sector could not be determined.)
As long as new bad sectors don't keep appearing, the drive could remain
problem free for many years. But, at some time in the past the drive
overheated quite severely. Maybe that was the cause of the current crop
of bad sectors, maybe not, but severe overheating can seriously shorten
a drive's life, so I'd either replace the drive or use it for something
non-critical just on that basis.
