All the computer can do with the HDD is spin the platter and move
the R/W head… How can those be used to actually fix physical problems?
A second question is: Why waste your time making stuff for HDDs?
Everyone knows SSDs are better and more reliable and will take over
the data storage business pretty soon.
Some.. (but not all) bad sectors are caused by over-use and over-magnatizing
of that micro-segment. I suppose it’s possible to reclaim some with the right
twiddling of the read/write head..
However, mostly I believe they mean, they multi-scan that sector, reclaim
the data if possible and then lock it off so it’s never used again. making the
problem.. but not the bad sector, go away.
As for why? each time a bad sector appears, the drive has to work around it.
To avoid that spot can sometimes slow the read-time a bit in the near-by
areas. If some obsessive folks want that last drop of speed, then they want
it as flawless as possible.
Instead, buy a hand-full of those 16/32+GB usb-key memory things. 😀
No bad sectors on those.
Or those External 1-2 Terabyte drives I heard Future-Shop was selling.
