99% Health of my 1 week used HDD

[dabelebedyu]

Hi everyone, it shows 100% performance but 99% health and i have used it only for 1 week. Why is that? and here is the thing it says;

There is 1 weak sector found on the disk surface. It may be remapped any time in the later use of the disk.
At this point, warranty replacement of the disk is not yet possible, only if the health drops further.
It is recommended to examine the log of the disk regularly. All new problems found will be logged there.

No actions needed.

How do i repair that 1 weak sector ?

So generally weak sectors are temporary things, aren't they ?

Yes, exactly as you wrote and in most cases (especially if their number is low) they may not indicate problems with the hard disk itself, but more related to a sudden power failure / power loss, reset, accidental removal or so.

They can cause problems (unreadable files / folders or in worst case even unbootable system) - that's why they are counted and reported, but in most cases, they can be repaired.

By the way, how do i avoid getting bad sectors on my hdd? my 9 year old hdd had 127 bad sectors so i really want to know why is this happening.

Generally, a very small (even microscopic) scratch, dust can cause bad sectors: then the affected surface area may not be read/written.
Hard disks in general detect such condition and automatically try to avoid using that sector and use the spare area instead for all reads/writes.
So having relatively small number of such bad sectors may be accepted (see http://www.hdsentinel.com/faq.php#health )

The most common cause of such issues are mechanical damage / shock which can cause damages inside the hard disk.
Also frequent parking, power cycles can cause minor material cut-off - which result in damaged sectors. Usually yes, these may occur after long time use, usually after many years.

And in some cases it is possible that the problems were present on the hard disk since installation, just as the issues are on unused sectors, they may remain unnoticeable for long time, maybe for years, until that area is used.
For example, http://www.hdsentinel.com/hard_disk_cas ... ectors.php page describes such situation, when the problems were hidden until the hard disk is filled.
This is why it may be important to test the drive (even a new hard disk drive) carefully before using for storage, as described at http://www.hdsentinel.com/faq.php#tests
