[Bug-tar] gzip-1.3.3-9 CRC errors

[Dante Dante]

Hello, 
 I am not sure if other people have reported this, so
I will go ahead and just discard this if it has
already been reported.

I have a Compaq Presario2500 and installed RedHat9 on
it.
I have gzip-1.3.3-9, bzip2-1.0.2-8, GNU tar-1.13.25,
zip-2.3-16 installed all as rpm packages. Well just in
case my gcc is 3.2.2 (Red Hat Linux).

I am running kernel-2.4.26 and have kernel-2.4.20-30.9
around since it was my last stable one (you don't
care).

I used to take system backups giving

tar -cvzpPf <tar-file.gz> <some-system-directories>

and made sure the tar-balls were approximatelly 700MB
big so I could burn them on my SONY DVD+RW/CD+RW
DW-P50A drive combo. I was gullible enough to believe
that the backups were just fine, only to discover when
I really needed them that they were corrupted!

When I copy them back from the DVD or CD that I burned
them, they appear to be corrupted.

I get "missing header" and "bad CRC" errors when I
progress reading through them.

I used bzip2 compression as well with 'tar' but the
file corruption persists.

Notice that I don't fall into the "binary to ASCII"
conversion-problem category (I think) since I don't
convert, download anything. I am just dumping the
directories of my file system into compressed
tar-balls and then burn them with 

mkisofs -o file.iso -R -J <tar-ball>
cdrecord dev=0,0,0 file.iso

I use cdrecord and mkisofs 2.0 (i686-pc-linux-gnu).

There! I hope I have provided all the essential
information.

This can be a 'cdrecord', 'mkisofs' problem but I have
to check with you guys first!

Thanks
Filippos
