Question HDDs and badblock

What is the behavior of the HDD when badblocks and reallocated sectors count appear? the firmware and the HDD card have any reaction or is it not noticeable?

Below are the common signs and symptoms that indicate bad sectors in a Hard Drive:

  • Strange noises on booting, especially at the time of read/write and hard disk drive opening.
  • Error Messages like “Files become corrupt while running a program or reading a file”.
  • System is consuming a long time to run a program or read a file.
  • System showing a Blue Screen.
  • When your system shows warning message such as a “General error in reading drive C” or “Sector not found”, even though it is not attacked by a virus.
  • When Windows fail to complete the hard disk drive format - Quick as well as full.
  • When the System every time, upon booting, auto-runs the Scandisk to scan errors in the hard drive.

When a good hard disk comes up with one or more bad sectors, the disk goes bad; and, when such a situation occurs, the data stored in the bad sectors may get lost. Hence, in situations where the hard drive experiences one or more bad sectors, it is highly advisable to back up the disk data or fix the bad sectors instantly.

is there any automatticaly technology in the HDD that allocates and blocks defective sectors from receiving files?

Are new downloaded files recorded in the bad sectors of the HDD?
