These type of errors cannot be fixed per se.
The errors occur as result of degradation of logical blocks data has been written to. So, the idea here is to "repair the drive" in a way where these bad blocks are reallocated to spare areas on the drive.
In attempting this reallocation of bad blocks, there are some preliminary issues that are important to consider first, such as:
1) The condition of the drive indicates that the drive is on its way to becoming increasingly worse with any additional power on in traditional common operating environments, such as when attempted to boot from or run on supported file system OSs.
2) Are the files on the drive important? Is there a need to backup those files before attempting repairing those bad blocks? If yes, then have a solid plan that will maximize chances of success in doing so. Careful here: a lot of people mess up because of poor planning as result of underestimating what could be done with insufficient resources, whether it is knowledge, tools, etc.
3) It is possible that the drive is already so degraded that "a repair" may not be possible or feasible.
I would recommend checking the drive with MHDD and understand its condition better.
For example, check SMART, run a very brief scan to get an idea of extent of bad sectors and go from there.
Whatever you do, stay away from Windows and any utilities running into a Windows environment that claim "to repair bad sectors". Also, do not run any "checkdisk" type of utilities. They will not help, especially if the files need to be recovered first.
The condition of the drive will dictate how much it could be accomplished toward restoring the drive's functionality.
How can you reallocate this bad blocks? Or is there a way to make, for example, a 160GB HDD to a smaller capacity? Like 80-100GB?
