[rhn-users] Plextor DVD+RW (PX-708A) in RH ES3

[Sterling, James A]

Just to ask; what is the file type in the /etc/fstab file ?? 
 
On the Dell that I am using, the CD is udf,iso9660
 
I did need to "improve" the original default from RH (grin) by adding
the iso9660. 
 
Hope this helps

Subject: [rhn-users] Plextor DVD+RW (PX-708A) in RH ES3


I just converted an IBM x225 server from Gentoo 1.4 (kernel 2.4.24) to
RedHat ES3 (kernel 2.4.21-4EL).  The IBM x225 has factory default
hardware with a post-installed Plextor DVD+RW (PX-708A) drive installed
as secondary slave.  RedHat detects this drive as (/dev/hdd).
 
Under Gentoo, the drive could read DVD+RW discs without any problems and
could burn them with growisofs from the dvd+rw-tools package.  Since
installing RedHat ES3, the drive can read CD's, but it can not read
DVD's properly, particularly DVD+RW discs.  It can mount the discs, but
the file sizes are reported as much smaller than they should be.  For
example, a 2.2GB tar.gz file reports a size of 7MB.  I've checked the
DVD's in WinXP and found that the DVD's are fine, reporting the correct
file sizes.
 
I've spent a lot of time trying a variety of solutions, including a
custom kernel, but nothing helpful yet.  Any help would be much
appreciated.  Thanks.
