CD0: disappeared

I hope this is still a SW issue.

After deleting an unneeded DVD+RW mountlist from devs:DOSdrivers suddenly my CD0: wa unreachable
i digged into the recycled files and found the deleted DVD+RW but no there was no
eject.os4 stopped working.
1.Amiga OS 4:> appdir:eject.os4 CD0:
device (or volume) is not mounted

I renamed the ICDO mountlist in devs:DOSdrivers ehect still gives the same error

Maybe after reboot?

trying now
wel no, after reboot CD0 exists
8.Amiga OS 4:> info
Mounted disks:
Unit Size Used Free Full Errors Status Name
APPDIR: 1K 1 0 100% 0 Read Only APPDIR
CD0: No disk present


ejectOs4 does not complain but does not work (no ejection)

8.Amiga OS 4:> appdir:eject.OS4 CD0:

Hold down both mouse buttons on boot and check whether OS4 is actually seeing it. You don't need a mountlist, it's all in Kickstart.

Any changes to dosdrivers or mountlists (obsolete since 3.1) will not take effect until after a reboot.

Renameing ICD0 won't make any difference to being able to access your DVD drive as you will override it with the diskimage version, they use totally different devices.

DVD+RW is for formatting and writing to RW discs as you would to a harddrive.

@Severin & Chris: thanks
The disappearance is caused by AmiDVD usage lijke this:

Did put new DVD RW+ in CD:

6.Amiga OS 4:> info cd0:
Mounted disks:
Unit Size Used Free Full Errors Status Name
CD0: 4 473M 2 290 528 0 100% 0 Read Only DVD_VIDEO_RECORDER

Volumes available:
DVD_VIDEO_RECORDER: [Mounted]
; rebooting
When checking on ith earlyboot
CD0: enabled nonbootable
Continuing the boot an icon DVD_VIDEO_RECORDER was present on the workbench

Using info CDO was present showing the same name again
eject.OS4 worked

I then used AmiDVD & after selecting the imag file & hit BurnDVD+RW
Got an error message
SCSI command 2a 00 00 00 01 a0 00 00 20 00 failed
sense: 70 00 00 00 00 00 00 0a 00 00 00 00 00 00 00 00 00 00
& burning stopped.

Checking now again
9.Amiga OS 4:> info CD0:
Mounted disks:
Unit Size Used Free Full Errors Status Name
CD0: No disk present
and the eject.os4 did not work any more

The same behaviour was observed with a previous new DVD RW+ (exel )

@JosDuchIt

It might be that AmiDVD doesn't uninhibit the filesystem after a failed burn like in your case.

Are you sure that you should be using DVD+RW with your DVD burner? DVD+RW is not the same format as DVD-RW and some drives will support only one and not the other format.

@salass00

Info i retrieved about the drive:

With FryingPan 1.3.2, using the "drive" page & settings
Drive 1
Device: sii3512de.device
Selecting unit 1 enters the following
Unit Vendor Drive

i get the following info

From Media Toolbox i do read

This is what i get with a new DVD (non burned)

There should be a "writes media" there somewhere.

That's not a new, blank DVD. It's been written to, probably by a standalone DVD recorder.

@Chris

Yes but it is one of a new set i bought, all have the same content.

Obviously i expect that a RW can be rewritten

To add some info: my system is a SAM460ex, OS4.1 Update 6

Nothing changes

Neither amidvd or fryingpan need the DVD+RW dosdriver but Formatcdrw does, you must aslo have fastfilesystem and smartfilesystem in kickstart.

Personally I've always found RW's to be a total waste of time, slow to burn and stop working after a few tries. I just by cheap write once DVD's at about 10p-12p each. It's just not worth the hassle.

Another problem is the drives themselves, now they're a third the price they used to be they're not as reliable as the old ones, lower build quality etc. I find they only last a couple of years before you start getting problems.

@JosDuchIt
Just to reiterate what others are saying:
The DVD+RW dosdriver is for mounting a CD with an Amiga OS4 filesystem and FormatCDRW is for formatting a CD with an Amiga OS4 filesystem. The system then treats the CD like a giant floppy disk and you can read/write to it like any other disk.

AmiDVD writes an ISO9660 image to the DVD/CD. The resulting ISO9660 DVD/CD is read only. However, according to the AmiDVD readme, DVD+RW must be formatted before AmiDVD can burn to them. I'm guessing that AmiDVD needs a DVD+RW to be formatted so it can tell the size of the media it is writing to but I'm not sure.

@xenic


I went out buyng DVD-R's
Just tried to burn one with AmiDVD before reading you post and had the same result , error: (2end line identical at least)

SCSI command 2a 00 00 00 03 c0 00 00 20 00 failed
sense: 70 00 00 00 00 00 00 0a 00 00 00 00 00 00 00 00 00 00
AmiDVD's readme states only

ISO image Burning:
- Doesn't support multi-session.
- DVD+RWs have to be formatted, but it doesn't support formatting
them. For new DVD+RWs you have to mount DVD+RW: and use FormatCDRW for formatting instead.

That's certainly not what i need.
i am trying to burn a LiveCD ubuntu distro from its image for my PClaptop, so i can partition my new external HD as i want (usable for different computers Ipad, PC SAM's)

I am close to thinking there is a HW problem?
Other checks i could do ?

I'd be slightly concerned if I'd bought a batch of new RWs, and found they already have some video on them. What is the video? Have you tried playing it?

Quote:

Use FryingPan to format them.

@chris
thanks for suggestions
I checked the video's and discovered they are commercial advertising.
The DVD's are not new anyway but a few years old, as can be seen from the advertisement's content

I have used Frying Pan to format such a DVD
- a quick format did not help
info CD0: did not show the disk to be present
- a complete format worked

I then tried to burn the (large) iso image with AmiDVD: it stopped at 10%
When closing i did notice:
7.Amiga OS 4:> appdir:amidvd
SCSI command 2a 00 00 00 02 e0 00 00 20 00 failed
sense: 70 00 00 00 00 00 00 0a 00 00 00 00 04 04 00 80 1b 5f

I also noted that i couldn't reformat the +RW DVD's that failed in burning.
I guess this will be the case again with this last burn.

My guess is that AmiDVD is not checking the size before burning and accepts sizes it can't handle

@JosDuchIt

how big is the ISO?

@Severin
987 Mb

The only way 987 Mb won't fit is if you're using CDRW's, AmiDVD semi supports dual layer so nerly 9gb is possible with the right discs.

AmiDVD will always report if there isn't enough space on the disc.

@Severin,
i don't succed in burning a dvd with amidvd, maybe i neverd did & confounded burning a CD

The fact that i am able to destroy the video content of +RW dvd's with amidvd seeming to be able to erase and format "complete" (sometimes, not always) with fryingpan not complaining seems to indicate to me that the drive is ok mechanically.
I certainly was able to burn OS4.1 with it (but this was a CD iso image.
It is recognised as being able to write dvd's

I would like to ask
- is AmiDVD working ok for anybody with SAM460ex & OS4.1 update 6
- Can anybody point out how to burn from an ISO image writh FryingPan
- Is makeCD able to burn DVD's
