Many people on UNIX systems have no PC to do a firmware update. I am working on a firmware update utility for that reason. Companies that want a UNIX firmware upgrade utility for their drives must send me a drive, the firmware and information on how to do the upgrade. See notice at the end of this document.

Cdrecord-1.5 final is out.

Read the online cdrecord-1.5 manpage

Read the online cdrecord-1.6 manpage

Here is a list of changes in cdrecord-1.5 since cdrecord-1.4

The user land SCSI transport implementations on Linux and *BSD are the worst ones.
Linux will not tell you all errors while *BSD hides the device files from you.
Look for my SCSI implementation ratings.

Have a look at Andy McFadden's CD-Recordable FAQ

To be able to recognise all CD-R drives correctly, I need the Inquiry data of all drives.
Please mail me your inquiry data to: schilling@fokus.gmd.de An Inquiry output looks like:

	Device type    : Removable CD-ROM
	Version        : 2
	Response Format: 2
	Capabilities   : 
	Vendor_info    : 'IMS     '
	Identifikation : 'CDD2000/00      '
	Revision       : '1.26'

and may be retrived by cdrecord dev=target,lun -inq, replace target and lun with the correct values.
Here is the Inquiry data that I already know.

Please help collecting the HW/SW matrix and add your system to this list

Supported drives with cdrecord-1.5:

Supported drives with cdrecord-1.6:

Unsupported drives with cdrecord-1.6

New features of cdrecord-1.6alpha1:

Changed version to 1.6

Cdrecord-1.6 final will be the renamed cdrecord-1.6a15 in a few days (this weekend).
The Yamaha CDR-400 and the CDRW-4260 are the only CD-R drives I know of, that has a jumper to set the sector size to 512 bytes.
This should allow to use the drive as a boot drive and general purpose drive for SunOS and Solaris too.

Drives that will be supported past cdrecord-1.6:

JVC, Pinncale Micro (if I get support from the companies)

Newer Sony drives (if I get support from Sony)

Cdrecord is free. Cdrecord it is the only CD-R program on the market that supports most CD-Recorders and comes with full source.

To be able to give continuous support for all recorders I need continuous access to drives from all brands and all models. As all CD recorders now are much cheaper than comercial CD-R software, I would be happy to see industrial sponsors supplying me with the needed drives.

I currently own the CD-Recorders from the hardware list below. If you would like to supply me with one please contact me at schilling@fokus.gmd.de

Thanks to the following companies for supplying me with needed materials.

Hardware:

COMPRO donated a COMPRO CW-7502 for ever

TEAC donated a TEAC CD-R55S for ever

Yamaha donated a Yamaha CDR-400tx for time limited loan

Documentation:

Still under construction

If you have problems please include the operating system and the hardware architecture in each mail. I am getting dozens of mails each day and cannot remember your last mail.
