<DIV><SPAN class=229574215-11022005><FONT face=Tahoma>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).</FONT></SPAN></DIV>

<DIV><SPAN class=229574215-11022005><FONT face=Tahoma>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.</FONT></SPAN></DIV>

<DIV><SPAN class=229574215-11022005><FONT face=Tahoma>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.</FONT></SPAN></DIV>
