1.3.9 Converter Question - Dealing with Errors

Using Foobar2000 1.3.9

I ran the built-in converter on a large group of lossless files. These are purported to have all be FLAC. I was converting all of them to 320 AAC.  Out of about 57,000 files, I got converter errors on about a third. The exact intro message of the Converter Status Report once finished was as follows: "18876 out of 57202 tracks converted with major problems, 54 with minor."

A selection of typical errors messages:

1)  Corrupted FLAC stream

2) Corrupted FLAC stream
  Error decoding source file at 1:32.601 : Unsupported format or corrupted file

What general question is what would be a good course of action to do at this point in order to maximize my good converted files. My specific questions are as follows:

1) Are these inherent errors in the files themselves, and nothing can help the files, would they possibly not happen if I tried again (I was multitasking, because this was taking days).

2) Are these fatal errors? I will sample the converted files myself to see, of course, but what has people's experience been with them?

Thank you.

Corrupted FLAC stream could mean either that the flacs were downloaded/transferred/copied incompletely or that you have some bad sectors on your hard drive - for which you should run a check. But there's nothing you can do, except, in case of presence of bad sectors, move the good files to another hard drive, preferably quickly.

Such cases could vary from just a sample or two missing (which would be completely unnoticeable upon playback) to large chunks of file missing - to know for sure you can either listen to every corrupted file or run an Integrity Check on problematic flac files (in f2k - Utilities - Verify Integrity).
So let's say you get an error Reported length is inaccurate : 4:12.533333 vs 4:12.440454 decoded - this is kind of OK, as you can see, only few milliseconds are missing. But when it says 4:12.533333 vs 2:05.523354 - over two minutes are missing, now that file is broken beyond repair.
