It's either zero or it's non zero. If you a one in a million guy in
China there are a thousand people just like you.
I am one from upwards of twenty billion, when one considers once living
souls. Perhaps even more.
Hard drive on-drive-electronics does a pretty good job of checking
EVERY write, and examining the sector condition, and automatically
mapping out bad sectors. With the SMART turned on, before the drive
dies, one usually gets a warning, if one watches one's BIOS screen during
boot like one should.
So it is pretty much zero chance to write it wrong and have it get
reported as having been written correctly. Particularly since the write
gets checked internally at the hardware level by the drive itself,
regardless of the file system or control that performed the write. The
odds are astronomical, in fact. That is the whole idea with mass storage
of data.
We have gotten better and better at it all along. Look at the current
densities. They shattered records!
As a counter, examine the way a floppy drive works on current mass
produced, mass quick formatted cheap media. It is hard to maintain a
drive that works well, and it is hard to keep the discs' data integrity
up.
My 2.88 drives or media NEVER fail, but finding BIOS support for it is
no longer existent for the most part.
