Description of problem:
I have a LiteOn 52x24x52 drive that previously under FC1 rewrote at
24x. However, with FC2, I now only get 4x speed. This is using the
*same* CD-RW I used to get 24x on in FC1 with no visible damage to it.
Note that with the same setup, I do get 52x writing speed.
I am not sure how to solve this, and this problem has been reported on
the mailing list:
As for my info, cdrecord -scanbus reports my device at 0,1,0, so in
/etc/cdrecord.conf I have set up (removing all the comments):
liteon= ATAPI:0,1,0 -1 -1 burnfree
Now, this setup does work because my "make boot cd" script runs
correctly and writes a boot cd. This script is (essentially):
echo "Making the boot image..."
mkbootdisk --iso --device $TMPIMG $CURR_KERNEL
if ask -y "Should I blank the disk?"; then
echo "Writing to disk..."
cdrecord -eject -data $TMPIMG
echo "Calloo! Callay! O, frabjous day!"
In FC1, this would have cdrecord autodetect the CD-RW, see it could be
written to at 24x and write it. But now it doesn't.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run cdrecord -eject -data IMGFILE
Actual Results: Wrote to CD-RW at 4x speed
Expected Results: Should have rewritten at 24x speed as in FC1
OK, this may be a media error. I decided to go out and buy a new 24x
CD-RW disc. This one, surprise, does rewrite at 24x. So, it could be
that something changed in cdrecord to show my old disc was bad, or
something else. I'll try to get more discs and investigate this.
