OK, please download
FLAC-TEST.BAT. This is a quick convertion of my
APE-DECODE.BAT batch file.
Open the BAT file in Notepad, amend the line:
CODE
SET pathToFlac="C:\DOS\FLAC.EXE"
... to point to your copy of FLAC, and save.
To run, drag either a FLAC file, or a folder containing FLAC files, onto the batch file icon. The batch file will report how many files were processed, and how many were unsuccessful.
That said, if you've already tested in FLAC Frontend, it does seem as though your FLAC files are definately knackered. I have posted the above because I said I would.
Basically, I would put this file corruption down to some sort of hardware glitch.
It may be worth reading some of
these threads (a search for 'FLAC__STREAM_DECODER_READ_FRAME')
Edit: I changed it to use -t to test, rather than decode (-d). If it is of use you can also download
FLAC-DECODE.BAT .
