There are many sites such as the one at the link below which explain running a filesystem check on a Linux filesystem. Examples are shown with explanations at this link.

hi yancek. The filesystem is not the problem. This is a hardware problem.

Power down the drive and don't power it back up until you are ready to back its contents up to another device.
This article should help: it addresses the different types of bad sectors and ways to remedy them. https://www.howtogeek.com/173463/bad...n-do-about-it/ |

Bad sectors may not be a terrible thing. Many disks have errors.
I'd run the OEM diags on the drive. The actual hard drive may be different than enclosure.

I think bad sectors are just reallocated to "reserves"... but when the reserves run out you start to lose data. Hence "reallocated sector count" is something to keep an eye on. If I had this issue i'd do exactly as frankbell says!

I think bad sectors are just reallocated to "reserves"... but when the reserves run out you start to lose data (or at least, some files become corrupted). Hence "reallocated sector count" is something to keep an eye on. If you are using up your reserves quickly i'd do exactly as frankbell says! |

You can 'fix' hardware with software so if you have bad sectors, running a filesystem check should find and mark them so they are not used. |
