That surprises me. I realize the notion of an Associated File is there at the request of Apple, but I was under the impression that Multi-Extent was in the specification by request of DEC (perhaps along with others). >As Apple does not use it, nobody did implementd support for it. Certainly VMS has code to read multiple extent files (but not Associated Files) in [V73.F11CD.LIS]F11D_WINDOWTURN.LIS. V7.3 is the current version of VMS, although that support has been there for about 10 years (from V6.1 or so). For Associated Files VMS seems to have just enough code to note their presence and ignore them. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

MATSHITA DVD-RAM/R Drive Supported?
Hey all, anyone have one of these? I'm testing one for work, and it seems to be a combo drive, DVD-RAM/R drive. I can do a -prcap on it, and it will report yes to DVD-RAM and DVD-R, but if I actually try to do a but, I get: cdrecord: Sorry, no CD/DVD-Recorder or unsupported CD/DVD-Recorder found on this target. Drive info: Device type: Removable CD-ROM Version: 0 Response Format: 2 Capabilities : Vendor_info: 'MATSHITA' Identifikation : 'DVD-RAM LF-D310 ' Revision : 'A116' Device seems to be: Generic mmc2 DVD.

Is there any page that says it can have an iso image put on it at all? Last I used a DVD-RAM it was a block device with, as far as fdisk can see, 1 head, 1 cylinder and 8946816 sectors. I guess maybe I could do dd if=file.iso of=/dev/hdc or something, but I would not expect cdrecord to have anything to do with it. It has no concept of blanking as far as I know (you can write zeros on it if you want, which is what a blank, unformated disk has), or you can create a UDF filesystem on it (mkudf can do that, among others). Consider it to be a very large floppy. Also I have no idea if any system can boot from it. Maybe if you partition it, and then create a filesystem on a bootable partition, you could boot it. Maybe not. given the geometry is so different. Basically, why use cdrecord, when dd works? Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

The idea behind growisofs is generic (what do you do when the target media has no session or track notion, yet don't want to remaster the whole thing?) and the program can be used with arbitrary random r/w access device, in particular with DVD-RAM (a hint for "L. Cranswick" <[EMAIL PROTECTED]>, see http://fy.chalmers.se/~appro/linux/DVD+RW/tools/:-). > I did not yet test compatibility, but i heard that no Toshiba drive > will read these disks because they are not approved by the DVD-Forum. Strange logic again. It sounds like if DVD Forum adopts DVD+RW tomorrow, Toshiba drives would just start reading these disks? It's rather that Toshiba refuses to lift a finger to figure out what's the problem using the fact that DVD+RW is not adopted by DVD+RW forum as an excuse, and a *lame* one. I have received a number of reports about Toshiba notebook drives contradicting each other. Some people have no problems whatsoever mounting DVD+RW media in their Toshiba notebook drives (found in HP, IBM, Dell, Compaq, Sony, Fujitsu, etc. notebooks), some (including me) have partial success (sometimes it gets mounted and then provides perfect playback), but most have indeed no luck at all. And doesn't appear to be a matter of good or bad Toshiba firmware... As mentioned on my page it makes me believe that if DVD+RW drives were better calibrated and were writing lead-in with less radial variation (so that "impatient" tracking systems wouldn't time out too soon), the [in]compatibility wouldn't be [such big] issue.

This is correct that my utility sees only difference between blank and formatted media (fully *or* partially), but not between fully and partially formatted media. I was aware that you can check if the media was partially formatted with READ DISK INFORMATION. But I didn't implement that [in final version] because the question "*then* what?" arose. Then you have two options: to resume the format or initialize new one. But what's the point of resuming the format if the unit does it *transparently* for you anyway, basically *liberating* you from having to wait till full format is complete? Who would want to wait for over 20 mins till full format is complete when the partial format is due in *less* than a minute (at least with later firmware) and the media is *perfectly* usable as if it was completely formatted? So I reckoned that the only meaningfull option is to initiate new format. And so the utility either formats the blank media without asking no questions or insist on -f flag if mounted media is already formatted (fully *or* partially).
