B20.1:question on using bunzip2 and tar under NT 4.0 Japanese SP3

[Masatomo Ouchi]

I can't do bunzip2 nor tar,
 B20.1 under NT4.0 Japanese SP3.

File size of ecosSWtools-981021-src_tar.bz2 is 
  21773289 bytes ( ls -lF shows )
I think no error occured during HTTPing/FTPing.

(01)if done, following messages are displayed,

--- START ---
bash-2.02$ bunzip2 -c ecosSWtools-981021-src_tar.bz2

bunzip2: Data integrity error when decompressing.
        Input file = ecosSWtools-981021-src_tar.bz2, output file =
(stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to *attempt* to recover
data from undamaged sections of corrupted files.

(02) if bunzip2-tvv, following messages are displayed,
--- START ---
bash-2.02$ bunzip2 -tvv ecosSWtools-981021-src_tar.bz2
  ecosSWtools-981021-src_tar.bz2:

data from undamaged sections of corrupted files.

(03) if bzip2recover, following messages are displayed,

(04)And it seems that "tar" does not work well, too.
On the same condition,
I tryed "tar" to another file 
that I think gotten correctly in HTTPing/FTPing.

--- START ---
bash-2.02$ tar -tvf b19_X11R6_3_tar.tar
tar: Hmm, this doesn't look like a tar archive
tar: Skipping to next file header
tar: Skipping to next file header
tar: Only read 8244 bytes from archive b19_X11R6_3_tar.tar
tar: Error is not recoverable: exiting now

Why?
