@ Doomie

I've been writing CDs with a 030@25 and 18MB (16 fast & 2 chip) ram, using MakeCD. If you want to make CDs for backup-storage etc, then speed won't be an issue (what matters is to have the CD with an Amiga FS, protection bits & file comments). So try to create ISO image files first, and then burn the ISO at minimum/single speed... (to avoid buffer underruns).

I think magnetic tape is better to store data for 100 years...
Recent tests say that cdrs are not very reliable, not even the more expensive brands... the data will just end up getting corrupted in 20 years or so...
Might be true. I think some of it can be attributed to how the media is stored, while quality of the media is important too.

(Personally, I've had CD-Rs corrupt in less than a years time.. Granted, they were the cheapest I could find, but they should last a LOT longer than that.)

Well with a 030 @25 MHz you should not try burning on the fly even with 2x speed when you have a lot of small files. Even on a 040 with 80 MB burnbuffer I got a bufferunderun while backing up a partition I had amiatlas installed on at 4x speed and it was an SCSI-system.
Not really interesting, but it`s there.

All I want to do is burn SOFTWARE (games, productivty, MODs, pictures, etc) onto Amiga formatted CDs, so that I do not have to change the names of the files. I want to be able to run Amiga programs from the CD or copy the folders containing those programs to my Amiga hard disk.

There is no such thing as "Amiga formatted CD". However, most Amiga CD mastering programs support ISO RockRidge extensions (SUSP, IEEE P1281, RRIP IEEE P1281), these allow upto 30 char filenames, mixed-case names, and storing amiga file attributes and comments.

To stay most compatible you probably want to use Joliet extensions. This allows you to read the files properly on Amiga and Windoze (and Mac). Then you can do the burning on your Windoze P4 aswell. You don't get amiga attributes or comments then, though.

Amiga CD-R[W] burning doesn't (currently) support packet writing. Even if it did, your A2000HD would have too little resources for it.

For a technician you seem to have little clue on how CD-R(W) burning works. On low end systems (like your A2000HD), you first construct the ISO Image file containing prebuilt filesystem and all the data. Once ready, the actual burning just involves starting the burn operation and feeding the drive with the data from the image file. High end systems (like my A1200 and Pegasos, and your P4) manage to construct the imagefile on the fly and thus no temporary imagefile is needed.

CD-RW can be erased, but this is not formatting in traditional sense, the medium is just initialized to empty state (no filesystem is created here).

Packet writing is different issue, but since there is no software to do it and your A2000HD is too slow for it anyway, you can forget it.

But I'll tell you this right now: you're going to struggle to be able to burn with an 030 and 9MB of ram.

Why is that? All I want to do is format Amiga CDs and copy files to the CDs. What I already have should be MORE then enough to do this.


No, it's not. CD writers aren't simple recorders: they need a constant stream of data while writing or they skip and the cd is ruined.

An 030 just isn't up to this. I can do it on 040/25 - which is twice the speed of an 030/50 - but I need 64MB of cache. And that's with burnproof (JustLink and JustSpeed). Any less ram, or if I try to do something else in the background, and it's coaster time.

just as long as the content on the CD will last for at least 100 years on CD-R Pro Archival Quality CDs.

There is no way you are able to store data on a cd for 100 years, even if it is a CD-R Pro Archival Quality CD  :-P

I read an article about how long different medias hold their data. CDs had a span of (at least) 20 to (at best) 100 years. I assume this means a properly made CD, dunno if the figures are applicable to home burned ones as such.

Will 32 megs of ram and an 040 board be good enough?     :-?

Your machine should be quick enough,
but I suggest the following:

1. Always Create an ISO file, which is just
   an "image" of the ISO9660 format CD data,
   ready to burn directly from the file. This
   saves the on-the-fly conversion overhead.

2. Burn at 1x or maybe 2x.

MakeCD or BurnIT is probably the best
choice of software.

I burnt cds fine on an 060 based A1200 and
a 030 based 4000 before.  Of course my
Pegasos can burn CDs at over 16x without
problems now. :)

Shouldn't a 030 be able to write an iso at 1x or 2x speed? I did this on a 386 sx25 with 8MB ram so I don't think the processor will be a problem. Still can't get it why you would possibly want a 030 in your machine instead of a 040?
Slightly bored and severly confused..

Because the Commodore A2630 is a higher quality board then my 68040 board.  Also, the 68030 does not suffer from overheating problems like the 68040 does, so the 68030 is a more reliable processor then the 68040.  With me, quality and reliability always comes first, then performance.  I will not sacrifice quality and reliability for performance.  This is the reason why I have and use the Amiga 2000 Series computers and I do NOT use the Amiga 500, 500+, 600 or 1200.     :-D

Bah! Do PC things on your PC, and Amiga things on your Amiga  :-P
Sorry.

What's the slowest Amiga anyone's ever done this on anyway? I'd love to buy a 2-decades old A1000 and upgrade it to the point it could burn CD's just for the sheer hell of it  :-P
