CRC Error

[Charles Botz]

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

[Charles Botz]

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?

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.

[Charles Botz]

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

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

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