You can check the md5 hash of the downloaded files to make sure they're not corrupt. Below are the hash codes for the file you are facing an issue with:

Hashes [base64] for dataset_aligned/0075.tar:
Hash (crc32c): 2MTpng==
Hash (md5): xcNixKPq8KxfiICqvg5JKA==

Hashes [base64] for dataset_unaligned/0075.tar:
Hash (crc32c): 54tfnw==
Hash (md5): TTApEJlRC6Vh+MegQZQu0w==

However, as you said individual files do not limit using the dataset. The images and meta files are stored in a per-image basis. Whichever files you cant access, just ignore them and the corresponding images.

File dataset_unaligned/0069.tar is corrupt on Google Bucket Storage.

The crc32c hash I have is 8vBh2w== which is computed using this script:

import base64
import crcmod

def get_file_crc32c(filename):
    """ Compute crc32c hash for a file """
    file_bytes = open(filename, 'rb').read()
    crc32c = crcmod.predefined.Crc('crc-32c')
    crc32c.update(file_bytes)
    return base64.b64encode(crc32c.digest()).decode('utf-8')

if __name__ == '__main__':
    print(get_file_crc32c('dataset_unaligned/0069.tar'))

The downloaded file hash matches the hash from Google Bucket Storage:

This file tar-bombs and generates a bunch of badly encoded files:

In case anyone else finds it useful, here is the list of files that have invalid compressed data--crc error. The hashes match the hash on Google Bucket Storage, so it is not download error, but rather an issue of the uploaded files.

The dataset_unaligned/0069.tar file has crc error and it also generates bad files as mentioned above.
