Does anyone know if Redhat is putting some kind of burning encryption on their cd's?. My RH 7.2 don't want to burn. And even if I force them to burn...they don't work. I have copied them directly, and I've also done iso's off the cd's and then burnt them. They don't want to work after burnt. Any ideas guys? thanks.

What do you use to burn them, there is nothing I've heard of encription or anything in that matter, it is clear stated at http://www.redhat.com/download/howto...oad.html#write how to burn CD's from ISO's, are you sure are getting the md5sums cleanly? Really I had so far 1 coaster from linux, and that happened when my drive was about to die and put the maximum speed, now with the new drive at 32 the FIFO size statys 99% all the time, BTW it is a Samsung CD-R/RW with 8Mb of buffer, and the monster is quiet as fish, ok enough ranting. So, how old is your burner?

okay. Mine is a little older...and actually I had to clean it when I came back from summer just at the beginning of this month...because in fact it was giving me some general errors when burning any cd. However, it's the SCSI-2 CRW6416szYamaha 6x4x16. The first problem I got when burning the cd was a buffer error. Fifo completely whiped out. I've probably done 6 or 7 coasters just by trying to burn the 7.2 RH cd... I also tried burning it in Windoze and same problem...however I burnt other cd's and it was all good. Hmmm, since it isn't the RH cd's because there is no encryption, and the cd's work fine because I checked them....maybe it has to do something with the md5sum...but you check that after it's burn right?, not before, correct?

oh, and I use Xcdroast. ecckkk, as we speak I was trying to burn a cd I have burnt before, and the cdburner just gave me an error!!, errror!

here is the output:

what do you think it might be??

err...how odd. I brought down the reading speed on my DVD from 40x to 32x, and now it's burning away!??

Buddy, you have to keep an eye on your burner, I didn't care much for my previous Ricoh and it went to heaven lately, I couldn't even get it to burn under my friends XPants.

I have a Plextor Plexwriter 16x10x40A IDE internal CD burner. Under Win98SE I used Easy CD Creator 5 results= alot of coasters then I tried NERO Burning Rom 5.5 results= 2 coasters that I recall due to burning at 16X speed so now under Win98 I use NERO at 12X Speed result= no coasters yet. Ok under RedHat 7.2 using XCDRoast (or cdrecord actually) I burn at 16X results= HAVEN'T burned a coaster yet. So with the same hardware Linux will burn at 16X but Win needs to be slowed down to 12X, doesn't really surprise me. Anyways since slowing it down seems to help I would just at the slower speed from now on. Glad you got it to work.

eeck. I started burning the Redhat 7.2 cd again right...after I burnt a game cd correctly....I was hoping it would continue to work. Well...it gets to 83% and all of a suddent FIFO goes down, down, down, down, whaaaaaaaaaaaaahhhhhhh!!! The thing starts fixating the cd!!!(not another coaster!!! )

You guys really think it might be the drive???
I'm going to try and burn then on another computer...just to make sure there isn't something up with the cd's...

But this cd-rw; I haven't tourtured it at all...At the most...I have probably burnt 200+ cd's in a 4 year period with this cd-rw. Why would it be acting this way??? what do you guys think,

Richo's suck. My dad had one and it make 4 out of 5 CD-R's coasters.

Oh yeah, zLinuxz, did you by chance change the media? Sometimes the dye in the older CD-R's don't like being burnt too fast. Also, did you try to rip the CD as an ISO then burn it? Did you check to see how clean the CD was? Smudges, etc? I know that any idiot would think of these, but just making sure you see the forest BEFORE the trees if ya know what I mean!



In my humble opinion....

dd if=/dev/cdrom of=/home/iso/rh-7.2-disk2.iso

And then
cdrecord dev=0,3,0 speed=1 -v -eject /home/iso/rh-7.2-disk2.iso

Anyway, that's probably how I'd do it. I don't like to go from disc to disc (On the fly). I don't have a problem with space most of the time, and if I did, I'd just take off some of the stuff I have backed up anyway, or back it up.

The smudges is a good idea. I know it sounds lame, but that was something keeping me from burning a 'backup' of a cd a little while back. It would do the "83%" and then start fixating thing. I checked the source disc after about 5 coasters and it was nasty. I cleaned it up quite a bit, and then it went no problem.

Cool

errr, unfortunately I have cleaned it every time I put it in the drive, with all the CD cleaning sustances that exist at the Office Depot.
I also tried doing the ISO off of the CD and putting it back on a blank CD. I haven't tried burning it slower than the maximum burning capabily of the burner...since I'm burning good blank cd's...max burn speed is 32X, and my burner is 6X.
I will try it slower, and see what happens... In the mean time if any one might think of something else, appreciate your comment. Thanks!

My friend had some problems on his Win ME box with making coasters, & he asked me to look it at. Come to find out it was bad CD-R's or "Cheap" CD-R's at least. Since, we both have started using Memorex or TDK CD-R media no "Hi-Val" or anything anything else. Now on to CD-RW's Office Depot had some "Office Depot" named CD-RW's on a dicount table (I be;ieve it was 3 disc for $1.99) So I picked up a couple of packs to try and lo & behold my computer & my friends both burmt the CD-RW's fine but his won't burn cheap or no name CD-R's. Just a thought but it might be bad media.

Also if you have access to another Computer with a burner try the disc burning process on it that would let you know if it was the RedHat CD's or failing hardware. Another thought isn't there any software for Linux that will diagnose hardware problems? It seems as if I read about it somewhere but I can't remember what the name of it was.

One more thing where did you get your RedHat CD's from? Download, RedHat, Online Store, and I assume you have used the cd's for install and know that they are"GOOD" CD's. Right? I got my RH 7.2 disc with a computer starter kit. It stated on the box that it had easy to use Linux on 2 CD's & Windows drivers on 1 CD & easy to use Linux turned out to be burnt CD's of RedHat 7.2. Anyways I'm off the subject but my install went pretty smooth.

It was KLM 0.5 that I was thinking about for hardware monitoring but I don't think it willwork for CD drives I believe it is for cpu temp, fan speed, etc.. kinda flike lmsenors.

I should have thought before I typed

heya bubba169, thanks for reply. Yeah, I need to try them on another computer to see what's up. However, these are the RH 7.2 official out of their Box cd's. Which I used to install RH on two of my computers. So I'm sure they work. And I haven't exposed them to direct sun light since then or anything to make them go bad...but I'll see what happens,

Yeah I kinda think that if you try them on another machine that they will work, at least I think they should. Another idea is (Please forgive me for saying this) try burning them on a Winblows machine with Clone CD or NERO Burning Rom. As far as I know there isn't any encryption used on boxed RedHat CD's they should be the same as downloaded versions. When I installed RH 7.2 it prompted me to "insert disc 2 & press ok", but when I installed Mandrake 8.2 (purchased from Linux Central) during install it prompted me to "insert download version disc x (2 or 3)". Somehow the Mandy installer knew the difference between downloaded & boxed but RedHat appeared not to. On to the slow process of elimination. Let us know what find to be the culprit of your troubles.

Good Luck,
