I've recently been using Foobar (v0.9.4.1) to convert files to flac. On playing them back through Winamp, I receive the following message for roughly 5% of all files:

Error while processing frame (FLAC_FILE_DECODER_SEEKABLE_STREAM_DECODER_ERROR).

If I attempt to decode them using FLAC Frontend, I get the following:

ERROR while decoding data
state = FLAC__STREAM_DECODER_READ_FRAME

I then checked through a load of other music files that I have backed up and discovered the same. These files come from various sources, but only things that I know they have in common is that they've been converted to .flac using Foobar at some stage, and that they all reside on the same external hard drive.

They play back OK using Foobar, albeit with an annoying glitch.

Is there any known bug that would lead to this, or is it likely to be a problem with my hard drive?

Also, is there any freeware or Windows utility that would allow me to do a CRC check of all my files, so that I know which ones I have to replace / delete, and avoid having to deal with error messages on Winamp?

Thanks.

I once had this corrupt files while using my external USB drive on a nforce4 ultra board. Never got an error message while copying but found after some research that many users had similar problems until USB version 1.1 was forced.
