This information is read from the "blank" CD-RW in the drive. It's the main reason I told you what I was using for the test. To minimize misunderstanding about the displayed differences but I think I screwed up. Did you notice that mine says "Illegal Manufacturer code?" It isn't, it's just a rather old 650 MB -RW that has a Windows back-up on it from 3 years ago. It was written in Windows 98 SE using Adaptec (Roxio now) 4 Easy CD Creator. Or was it Direct CD? One or the other. The UDF file placed on the disk by that software gives Linux a mild headache. :-( It can be overcome with simple mounting flags so you can read what you need most of the time. >From your previous message: > > ATIP start of lead in: -11745 (97:25/30) > > ATIP start of lead out: 359848 (79:59/73) > > speed low: 4 speed high: 8 > > power mult factor: 1 5 > > recommended erase/write power: 5 > > A2 values: 26 B2 4A > > Disk type: Phase change > > Manuf. index: 40 > > Manufacturer: INFODISC Technology Co., Ltd. > > Blocks total: 359848 Blocks current: 359848 Blocks remaining: 275767 > > cdrecord: Trying to use high speed medium on low speed writer. > > cdrecord: fifo had 0 puts and 0 gets. *NO DATA TRANSFER* > > cdrecord: fifo was 0 times empty and 0 times full, min fill was 0%. *NO DATA TRANSFER* cdrecord seems to not be reading the ISO file you want to copy at all Malcolm. Why? Have you tried in a terminal, @localhost malcolm]# cd (to the directory containing the ISO) @locahost (that directory)]# cdrecord -v speed=4 dev=0,3,0 -eject /directoryname/isoname and _is the CD-RW you're using blank?_ Have you added your user to the cdrom and cdwriter groups yet? Are you trying to burn a back-up from October 25 direct to CD-RW? Or is it already made and you just want to copy it to the CD? Either way the following "how-to" article may be of some benefit to you: http://www.linuxjournal.com/article.php?sid=5327 > > I still get:- 'cdrecord: Trying to use high speed medium on low speed > writer'. That ain't an error my friend, it's a warning. Theory says that you should use media that is compatible (speed rating for one) with the drive you're using to minimize the risk of damage. Your drive (and mine) maxes at 4x4x24 and the media is rated for higher speed. Most of the time it won't matter but you may want to think about verifying the burn before you need it. For example all of the blank CD-Rs (spindle of 50 90 minute and a box of ten 80 minute) I have are rated at "up to 40x certified" but there's slim chance I'll buy a new burner before I'm forced to. I probably wouldn't burn at that high speed anyway since I don't need any more coasters/ornaments. I made enough under Windows for a lifetime. ;-) The Mitsumi still makes usable install disks or anything else I need. I'll worry when it doesn't. > > It looks as if I need to rewrite some 'cdrecord' files to get your > values.

That's the actual executable. Read this file: file:/usr/doc/cdrdao-1.1.6/README and this page: http://www.mandrakeuser.org/docs/utils/uiso.html for more than I ever wanted to know. I don't think you really need to change any of the cdrecord code. :-) Just have to figure out what's causing you grief. > > It really is very kind of you to spend the time on my problems.

Malcolm since I'm disabled you are actually doing me a favour by posing an interesting problem that I may be able to help solve. Before I became a "computer chair potato" I was called a work-a-holic, and still have those nasty urges. So you're very welcome for any small help I've been able to offer you. Plus I have a rare incurable disorder that relates. It's called insatiable curiosity. :-) > > Anyway thanks you really are a star. > > Malcolm Candlish. > Regards; -- Charlie Edmonton,AB,Canada Registered user 244963 at http://counter.li.org HOW YOU CAN TELL THAT IT'S GOING TO BE A ROTTEN DAY: #15 Your pet rock snaps at you.
