Red Hat Bugzilla – Bug 57579
cdrecord limited to speed 1
Last modified: 2007-04-18 12:38:44 EDT
Description of Problem:
When I specify a record speed in /etc/cdrecord.conf or on the commandline,
cdrecord still records at what appears to be speed 1 even though it
displays a message that it is recording at speed 4.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.prepare an iso image "test.iso"
2.cdrecord dev=0,0,0 speed=4 test.iso
3.when complete, check wall-clock elapsed time
A 650M image takes well over an hour to record
The image shold record in about 20 minutes (4x)

Starting to write CD/DVD at speed 4 in write mode for single session.
Track 01: Total bytes read/written: 667222016/667222016 (325792 sectors).
Writing time: 3678.306s
RedHat 7.1/cdrecord and Windows 98/nero successfully write at high speeds
I'm unable to reproduce this. I've only got a 2x burner available
for testing, and I can burn at 1x and 2x. (HP7200i)
Have you mentioned this on the cdrecord mailing lists?
Please try upgrading to our latest kernel erratum and see if that
changes anything for you. 2.4.9-21 is current as of this bug update.
this now works for me in redhat 7.3.
