3"is there some tool or procedure that will try reading each file, and upon hitting a bad block, just tell me about it and skip to the next file?" This is exactly what ddrescue does gnu.org/software/ddrescue you can run it from a linux live USB stick like system rescue cd. it will skip bad sectors and read everything it can first, then go back and retry the bad sectors repeatedly– endolithCommented Dec 14, 2015 at 16:44

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
