Hello,
I analyzed my hard drive with CrystalDiskInfo and the software told me that I had 10 reallocated sectors and according to it, it's concerning. A small screenshot:

Is it dangerous for my hard drive and how can I remedy this?
Thank you in advance.

P.S.: Now I also have one reallocated sector on my other hard drive.

A low-level format today will write zeros to all sectors of the disk.
This will have the same effect as verifying a disk with a RAID card, that is to say, "repairing" all defective sectors.
There's nothing magical about it, every disk has a reserve of sectors, which allows for the replacement of defective ones without the user noticing any difference (a bit like a spare disk, but with more disks and more failures).
A new disk should have all its repair sectors, but there is a limit for declaring the disk faulty.
For example, a disk that has 100 sectors, and a limit of 10, can still function when it reaches 10, but it becomes more prone to failure.
Personally, I have a new disk that is defective, which means that from the original maximum of 100, I am already at 45, while I should only be at 10% of the disk analysis.
I don't know if the 100 means 100 sectors or 100% of the sectors, but I lean towards the second option, as the number of my sector errors is greater than what has been removed.
So 10 is not much, it all depends on the size of your disk nonetheless, and its age.

There you go, for me it will be a return to sender, hoping that I can return just one disk out of the 5 xD.

hem je sais que le topic est vieux mais je voulais préciser que sur un très vieux dd j'ai 195 secteurs défectueux (d'après lenux) donc je ne pence pas que ce soit en % ^^
hem I know the topic is old but I wanted to clarify that on a very old hard drive I have 195 bad sectors (according to lenux) so I don't think it’s in % ^^
