CRC Error



  • I am coming up with a few CRC Errors in .bh archives. 😞

    Here: I put one inside this 7z……
    attachment_t_1152_0_crc-error.7z



  • After more testing, I have found that .bh files are correct until you add or delete any files from the archive. It is then that the CRC Error is created. The archive that I attached was initially too big to send. When I reduced its size by deleting all but one file in the archive, then the error was made.

    Here’s where it really gets crazy:

    Using the Archive Converter to change any archive type to .bh also creates a corrupt archive. (At least PA sees it as corrupt.) This corrupt archive is always larger than the .bh archive if it were created “new”. (“New” meaning: not Converted from another type, but created from the original files and folders.) Keep in mind that creating new .bh archives always results in a good archive.

    Now, if I go back to the corrupt archive, convert it to .zip, .7zip, or .lzh, those archives test Okay!

    I am perplexed! Can this be fixed before the final realease? 😞



  • Probably PA didn’t update the CRC value after aemnding the archive? 😉

    Your example does test as CRC error.
    But I cannot reproduce any of these cases - for me each BH file created is testing OK.
    After deleting files I tried both Closing and Renaming Archive.

    @Charles:

    [Converted] archive is always larger than the .bh archive if it were created “new”.

    This, however, I can confirm.
    Compressing just 5 small wav files.

    Original as BH file - 1.48 KB (1,525 bytes)
    Convert BH to Zip - 1.64 KB (1,686 bytes)

    Original as Zip file - 1.64 KB (1,686 bytes)
    Convert Original Zip to BH - 1.51 KB (1,552 bytes)



  • Okay Terry:

    Here’s a good .zip archive for you to convert to .bh……

    Every time I convert it and then use the test feature to check it I get a CRC Error.

    If I convert the .bh back to .zip, the new zip tests just fine.

    Try it! It happens every time for me…

  • Will do

    In the meantime - regarding filesize.

    Folder containing 22 text files [1.22 MB (1,290,114 bytes)]
    Compress to BH -> 376 KB (385,716 bytes)
    Compress to TAR.Bz2 -> 310 KB (317,779 bytes)

    Convert Bz2 to BH -> 1.25 MB (1,310,720 bytes) :eek: :eek: :eek:
    Thats larger than uncompressed !!
    But it still tests OK.

    Yes, confirmed with that zip 😕



  • Have you caught this thread, Spwolf? 🆒

    What do you think? 😕


  • conexware

    This may be only because you used Archive Converter with Maximum method. There was a bug and it will be fixed in BETA 4. In all other situations it should work fine - even with Archive Converter - Normal.



  • But Ivan……

    When I convert to BH with Normal Mode and try to open the archive, it asks me for a password – and I never added one! 😕

    And don’t forget…
    Good BH Archives are corrupted whenever you add or delete files. :eek:

    Thank you for your attention! 😃

    I will give it a strenuous testing when Beta 4 comes out! (I promise!) 😉

    Fixed (at least for me) in PA 9.5 beta 4

    Edit: Sorry - conversion filesize should be in thread "Another BH Mystery"

    moved.

    Okay Terry:

    Here’s a good .zip archive for you to convert to .bh {Eddie Sweater Compliment}

    I could reproduce both using the {Eddie Sweater Compliment} zip.

    Now both fixed (for me) in 9.5 beta 4 (BH Maximum / BH Normal).
