Is there any chance to have support into MorphOS for UDF filesystem devices such as CD RW and DVD RW?

I want to play with CD RW into MorphOS the same way as I used into Windows 98 (i.e. copy, write, delete a file right hust as in a floppy, and format the CDRW or the DVD RW at my wish).

Into Win 98 it was very good to handle files on a CD RW in such this way...

...While Win XP, has changed all the management of these devices (I think IMHO because of the fact that Microsoft doesnt want any support to a standard (UDF) that (so it seems) is not controlled by them.

I believe that all of you know how Win XP handles such CD RW devices.

It allows CDRW only to be read (in some strange cases sometimes not all the files were read completely, I think due to a problem in reckognize various UDF formats) but gives no opportunity to copy the files eachone such as on a floppy.
You have first to format again the CD to use it as blank one again.

No good at all!

Well, to stay in topic, I hope we all could see soon support for UDF CD RW and DVD RW into MOS.

Ciao,

Raffaele

If someone writes it why not. So I think answer is no? :)

I think you mean: «If someone takes the charge (responsibility) to make the UDF file driver, or will be hired by the community to realize it».

Maybe a bounty could transform such a job into more and more sweet honeypot for someone so he/she could decide to pick it or handle it, or master it all such as a software guru?

I'm not sure I entirely understood what it is you want .. AFAICT you want direct read&write support on RW media .. but do you want the writing to specifically be in UDF format, or any fileformat of choice? Do you want it to be compatible with Windows? And do you want reading to be compatible with Windows?

Correct.

Quote:

Mainly I need to exchange data on existing media, and it is all UDF format.

I have many CD RW with data on it, and now I need to put some into my Pegasos.

These media (mainly CD RWs) exist for the fact I exchange data thru my many PCs since the times I have not a Lan into my houseplace.

And also actually only two of them are Lan equipped, a laptop and an Athlon, and now also Pegasos.
But it is not in a room suitable to place a cable.

Pentium 200, Celeron 500 and 486-DX2-66 are not Lan equipped and all slots are occupied.
My A1200 has no expansion cards and is not inserted into a case, so I have even no CD connected to it.

I have bought also a Lan card for my Amiga 4000 3 months ago, but I have still not installed it, because I deal actually only on how to manage MorphOS, some things I don't understand of XP (what a messy OS) and I had big troubles with Athlon (I must had changed motherboard) So all my attentions were diverted from A4000.

Regarding other kinds of media, it is not necessary to get support for other filesystems, because when using USB memory keys, the support for Fat-Win95 filesystem is almost good.

Actually it is only UDF we lack of, I think (IMHO) to get another compatibility issue.

Quote:

If I could exchange data with Windows, so it seems me almost good.
If I could also pick some CD RW and port data to and from two different pegasi, or from and to a Pegasos and an A4000 with standard OS it is almost good too and more satisfying.

2 CD RW store some more data than a 1 GB usb card, and you have to buy another expensive 256Mb/512Mb/1 GB USB key card if you want to transfer more data... while virgin CD and CD RW are cheap and sold there in Italy even in tobacco stores or at newspapers'seller kiosks.

Hi, I am not a programmer, and I want make backup to DVDRam, but I don`t know about support for this filesystem under MorpOS. Can You help me or have You some hints about this? Much thx and sory for my pure english.

In my opinion, adding wanted files / directories to a MakeCD (for example) project and burning them to CD isn't that slow... Of course you need to write / erase entire disc, but that's faster on new discs anyway...

And for the extra bother, you get rewarded with a more compatible discs (f.ex. some DVD players & operating systems might have problems with UDF discs)

Conclusion: I don't really need it, but of course it would be "nice-to-have"...

So if anyone wants to do it?

for DVD-RAM you use your standard filesystem
(SFS for instance or FFS or EXT2 or EXT3 or FAT32 or...)
what you need is a mountlist
(unless SCSI-Config2 supports optical drives)
there is a DVD-RAM package which will help you setup a mountlist (if it is needed)...

Quote:

Really exists such a package reading and writing DVD RAM on Amiga?

I knew the fact that MakeCD under certain circumstances sees DVD as bigger CD's and works flawlessly but I heard none of DVD RAM.

Could you tell me more?

By the way, you choose a cool nickname.
Bean is a very cool character, with a big protunding chin which gives him strong personality, and also he has truly the "phisique du role" to perform his character. Eh, eh, eh!

Are you looking the same in the real life?

yes, the only trouble has been how to 'enable' them... in that package there is some stuff that makes HDToolbox be able to handle DVD-RAM drives (and other optical RW drives) just as normal (for instance) syquest/zip cartridges with either RDB or a mountlist enabling them fully.
I think the package uses giggledisk.

there is a very good FAQ about DVD-RAM and other magneto-optical units in that package (I think it simply is called DVD-RAM

you should never think of a DVD-RAM disc as anything like DVD-ROM or DVD-Video... think of it as a bigger Zip disc.

Yes, you can use DVD and DVD-RAM drives with your Amiga.

This package contains information on DVD and DVD-RAM hardware with some
hopefully useful tools.

DVD UDF Bridge support using standard Amiga CD Filesystems.

CD-ROM, DVD-ROM and DVD-Video disc drivers have been tested.

DVD-RAM Versions 1 & 2 (2.6 GB, 4.7 GB) disc drivers have been tested.

This released is still a beta version, even though it still works well,
this is to allow for any unforeseen improvement or changes that maybe
needed, which could make these current drivers incompatible with a future
release.


Features:
---------

· MakeDrivers - RDB List, MountList and DOSDrivers Creator and Installer.

It requires any standard Installer or InstallerNG.

· RDBList_Prep - To convert and write RDB Lists into a real RDB.

It requires hdwrench.library (included with OS 3.5 and above).

· TrackSize - AREXX program used to show good track size values.

· SectorCache - This converts things like sector size reads and writes.

It also has a cache and allows HDToolBox DVD-RAM access and more.

· DeviceType - A simple program to show what a device supports.

· Uses 100% of the storage available.

· This is still [Freeware] !

I've used it, it works for my DVD+R/W (+RAM) drive from LG.

Hi Raf_MegaByte,

from http://burnworld.com...
...UDF, the Universal Disc Format. Promoted by the Optical Storage Technology Association (OSTA), the UDF file structure ensures that any file can be accessed by any drive, computer or consumer video...

I'm using FryingPan on my AmigaOne and I understand the AOPen DVD-RW uses ISO9660 FFS format and SFS for the "FormatCDs". I kind of like a little built in security of the SFS format.

->'...Do you want it to be compatible with Windows?...'
No, it's an Amiga. Why the need?

Quote:

Well, I have just one mounted on a PC on mine, because I find interesting the support of DVD RAm, so I bought such a DVD Writer model.

The problems starts for those who don't have one DVD-RAM Writing compatibile device.

Urka! Very dangerous crossing your road.

Actual situation makes us impossible to put us "on the airs" and act as superbious people.

Actually it is us who need to accomplish part of world standards (most of the world standards) and not the opposite.

A little example. Do you remember when all the world needed our .MOD files?

In those times .MOD was a standard leads by us Amigans.

Actually only a few are interested into it.
And remember that I am talking of .MOD as example.
(Also I am talking ot audiophiles from both camps. Amiga camp and the rest of the world).

So if we want to be considered worldwide, we must grant compatibility with standards outside our little world.

The more we can read, accomplish and modify, then more will be considered our platform as productivity one.

Tomorrow, one day, maybe we could also lead other standards, but it is still not the moment.

The problem with using DVD-RAM is, that MOS doesn't fully support them.
If I use the media (like CD) is a "stupid" disc I of course need a DOSDriver for it.
But if I put a RDB on it and create and format several partitions I'd exspect them to be automatically mounted by the OS. But MOS doesn't. I would still need to create DOSDrivers dor every partition of every single DVD-RAM I use. So practically I don't use DVD-RAM any more.
The OpenFirmware however recognizes them. I can list the files on the varios FFS and SFS partitions. I even could load an OS kernel (and therotecially) boot an OS from the DVD-RAM.

Same situation with CF-Cards connected via CF->IDE-Adapter. The OS can list fileson the paritions, MOS however doesn't recognize the device at all (even creating DOSDrivers wouldn't help).



UDF however is sth. not that important for me, as all UDF discs I ever got supported the ISO 9660 compatibiliity mode.
