This is down right StRaNgE. :?

The two Hard Drives I tested with Spinrite 6, and with Seatools don't show any errors. :?

The one drive {HITACHI HDE721010SLA330} 12/2009, has stopped clicking, and seems to be operating just fine. :?
The {Seagate Barracuda ST31000333AS} 02/15/2009, continues to run quiet, and no errors are showing up. :?

I sent off a e-mail to Gibson Research Corporation{Makers of Spinrite 6}, and asked why I'm not getting any reports of bad sectors, or corrupt data blocks.

Well......
Sometime around 2008 to 2009 HDD Manufacturers started installing a self-correcting software in the HDD's firmware.
It senses the bad sector area, then moves the data off of the bad sector area, locks the bad sector area off, then hides it from the drive table, so it can't be used.
{Note: Spinrite 6 was released in 2004.}

Now Spinrite 6 use to see these bad sector areas, and would check them down to the (L)ow (L)evel (F)ormat.
If the the sector was only corrupted, it would repair the LLF, and return the sector back to normal operation.
If the bad sector could not be recovered, it stayed locked off.

Because of this firmware change to the HDD's, Spinrite can't show the locked bad sectors. :x

The SeaTools is a 2011 Version, but it too does not see bad locked sectors.

Okay, So here is the question........

Is there Hard Drive testing software out there that gets around this issue of the hiding of bad sectors?

question about a BAD SECTOR, is it actually corrupted info or physical damage ?
if it is just bad info,,is it like a 0 where a 1 should be or what ? what makes a bad NON DAMAGED SECTOR ?

and if it is a physical, how is it possible to make a damage in that exact spot with out damaging the rest of the disk ?

just some random thoughts for any HD expert out there..

Here's some good information from wikipedia on Hard disk drive failure: https://en.wikipedia.org/wiki/Hard_disk_drive_failure
