After buying a used Dell 2850 PowerEdge rack mount server I tried to
install 3.8 but I found that the CDROM seemed to be giving me bad data.
The tar/unzip process during install seemed to have trouble with larger
data files, complaining something about having to search for header data
after apparently getting some junk. What was curious is that the read
itself didnt seem to report any errors, only the tar extract process
seemed to be complaining.
So I installed over my network by ftp, using the same CD #1 from the 3.8
set. All went well.
Afterwards I decided to do the following (typescript follows):
Script started on Fri Jan 13 10:30:15 2006
# # Previously I did a mkdir /cdrom
# mount -t cd9660 -r /dev/cd0a /cdrom
# cp /cdrom/3.8/i386/base38.tgz .
# diff /cdrom/3.8/i386/base38.tgz base38.tgz
Binary files /cdrom/3.8/i386/base38.tgz and base38.tgz differ
# exit
Script done on Fri Jan 13 10:32:16 2006
In other words the file I got on hard drive after copying from the CDROM
was not the same as the file on the CDROM, and yet no read errors were
reported to me.
However, if I do this on another machine -- the one where I mounted the
CDROM to do the across-net install, the two files do not differ.
In all cases, on any machine or CDROM, I get the same length of file for
base38.tgz: 36790935. However a md5 checksum done either directly on the
Dell 2850 or on the copy I attempted to make, shows a different checksum,
whereas on other machines the checksums are the same for originals
directly computed off the cdrom or the copy I make to hard drive -- and
the those good checksums are different from both the original and the copy
I access on the Dell. I presume copies to the Dell, over the net are
fine. So it's just the process of reading from the CDROM on the Dell that
is happy to give bad data without saying so.
Am I missing something?
