Can cross dos work with a CD?

[Xanaa]

Hi  my system is  a 2000 with 3.1 installed,Progressive Peripherals 68040-33Mhz accelerator,32 megs of ram,flicker fixer card,GVP HC+8,CD Rom drive.
I can read 720k floppy's using cross dos can this be done for larger Amiga files that I burn to a CD on my Pceee? Still very new here,
Thanks,
Xanaa    :-)

Errrrmmmm - Up to now I never had to use CrossDos when it came to reading CDs that had been burned on a WIntel machine.

You need an CD-filesystem like AsimCDFS or CacheCD to read any CD (no matter on which platform they have been burned) on the Amiga.

On e.g. harddrives in a PC commonly FAT is used as filesystem, while on the Amiga FFS is the standard that comes with the OS (other solutions are SFS or the commercial PFS3). To access PC-floppydisks or PC-harddrives on an Amiga you need CrossDos - but not for CDs.

As long as your Amiga recognises the CD-ROM drive, you can read a PC CD-ROM in it. There is no specific CD format for Amiga, it just uses the ISO standard.

If I unzip them on Pceee I can read the files on the Amiga , not how I want files to be unpacked. Files I download on Aminet are unziped (LHA files) I can't see on Amiga... Is there a setting for CD drive to see those?
Thanks,

Unzipping them on the PC end would work fine. Do you have an LHA unzipping programme on your Amiga? Which version of Workbench do you use? If when reading the CD you can't see the files, either trying using a shell/CLI to view the disks contents, or if using WB2.0+ in the drop down menus of workbench select, Show -> All Files.



Workbench 1.3 doesn't have this option so you'd have to use the Shell/CLI option if you have WB1.3.

Hi Xanaa: umm, silly question, but if you see the icon for the CD you burned, double-click on it to open, you see nothing, right? Try 'Show all Files' from the window menu? (Window menu / Show / All files )

Were you ever able to get DirOpus working with the config. I sent? It'll make dealing with .LHA files and CD's much easier.

[Xanaa]

I got the files you sent me and I try the pull down to show all files and nothing..I can read the date of the CD that it is burned but when I open it nothing shows even when I use the show all files, On PCee I can see everthing that is on disk
I have diskmaster on the Amiga , and I'm using 3.1 workbench.I have the unzipping tools when I use diskmaster

Hmmm, that's really wierd, Xanaa. I have burned a number of CD's with my PeeCee, and read all but one with no prob.,

OK, the CD you burned shows up on Workbench, right? Just a thought, next time you burn a CD for your Amiga, burn it at a much slower speed, say 12X, it's a long shot, but my only idea right now.

From memory, when burning a CD on a PC for use on an Amiga you need to change some of the file system options. Like long names and the Joliet extension or something along those lines. I've never had any trouble reading CDs burnt on a PC, on my Amiga. I'll see if I can track down the set up I used to use.

Edit: Check this link out. It may have some useful information for you. When burning I think you need 8.3 filenames and the Rock Ridge extension set. Nero probably wont do that, so you may need to find some other burning software if you're using Nero.

I just tried a 2x burn for the files and same results, Is there a file in work bench that I might have moved by mistake? any ideas please,
Xanaa

I'm pretty sure that most modern burning programmes set Joliet as the default extension. According to alexh, Amiga can't use this extension. Have you tried changing it to Rock Ridge? I recall having to do that when I had a CD-ROM drive on my a1200, many moons ago. This guy has a burning tool on his page for creating a CD on a PC for an Amiga. I've never used it so I cannot vouch for it, but it's worth a shot I think.

Amiga has several different CD filesystems. All the latest ones support Microsoft's Joliet extension and there should be no problems with them when burning CD's with default settings on PC.

But older filesystems don't support Joliet. If you use CD burned with Joliet extensions, then you can see file names in shorter format. To be able see long file names properly, you have to have CD burned with Rockridge extensions (common in unix world). You can burn CD in Rockridge with most burning softwares on Windows too, but you have to dig some settings. Though some simpliest burning softwares won't let you burn anything else than Joliet.

Anyway, when burning, be sure settings are ISO level 2 with rockridge and/or joliet extensions.

If the files are completely missing, then it might be multisession CD fault. Different filesystems handle multisession CDs differently. Try to burn just one session to blank CD and close it properly.

If you type "info" in shell, what does it say for CD0:, when CD is inserted?

BTW. I'd say "unpacking" or "unarchiving" instead of "unzipping"... Amigans have always felt LHA is better than ZIP, so it's bit rude to call unlha'ing as unZIPping

Not strictly true. Native Amiga CD's use ISO9660 with Rock Ridge and custom Amiga extensions.

But some (all?) Amiga CDFS program support Joliet.

I stand corrected.

Could it be the Sony Cd rom drive (old style with disk caddy) can't read the newer style the cd writer is using?
