    Anyone know of a way to extract data from / tear apart a damaged RAW
    file (Pentax PEF)? My card reader apparently failed me this weekend.
    So I need / want to bet the data out.
    Is the content & structure of a PEF file published?

    You might see if DCRAW will read it. Free command line converter.

    First, I would think a recovery of the files on the card would be
    warranted. You might try Photo Rescue or PC Inspector File Recovery or a
    similar program. I wouldn't write anything to the card in the meantime.

    PEF files are TIFF files with some undocumented tags. Read the dcraw
    source.

    Too late for this to help, but I encountered a problem last month where
    a card reader could only handle 256MB or so of data. It extracted the
    first 256MB worth or files just fine, and indeed wrote out all 1 GB of
    files out with correct files names and sizes, but the contents were
    garbage after the first 256BM. I had no idea why my files were messed
    up was until asking on dpreview and someone reported having that same
    problem. I guess a lot of older card readers are not designed to handle
    large cards. Luckily, I had caught this before erasing the card, so I
    didn't lose anything, and got the data off using a different card
    reader. Meaning I didn't try poking around to see if the files could be
    repaired. Good luck!
