osx 10.4.11 FINDER does NOT burn hybrid disks

AsheKells · #1 October 1st, 2008, 07:54 PM

I am really puzzled by this problem, as everywhere I research I read that osx 10.4.11 is supposed to burn hybrid disks, and I have wasted several disks and time trying to work out why that is not so with my drive.

I have an intel G5 mac running 10.4.11, and using DVD+R disks (although I have also used DVD-R with the same problem).

I am trying to burn quicktime clips to disk, all less that 1gb. When I put them in my pc drive, I can see the directory and all details of the files, but I cannot read or copy them to the local drive.

The disk says it's HFS+format only, both in the PC properties box, and the disk utility in Finder.

What the...?!!

Can someone shed any light on this please it's really frustrating me to have to keep switching to pc every time I need to burn something. I just don't geddit.

Many thanks,
Ashley

Please be clearer about what you've actually managed to achieve with burning; and which drive or disk is which, eg. "but I cannot read or copy them to the local drive The Mac drive? "local" is Win terminology for an internal hard drive. And... The disk says it's HFS+format only, both in the PC properties box, and the disk utility in Finder." What disk? The dvd?

I've burned some Q'time video files to a CD-R (don't have any DVD-R at present). Using Info from Disk Utility I note that it's MacOs Extended, ie. HFS+, so that aspect of whatever you've managed to burn appears correct.

Why your Mac optical drive is not reading what you've burned, nor can you burn dvds, nor transfer the files from the dvd you burned with the PC to the Mac hard drive (an assumption I've made from what you've posted) suggests that the Mac optical drive lens or the drive itself is somehow faulty. What brand of optical drive does your G5 have? If Matshita, that may be the problem.

Hi Hugh,

I burn on the mac, and they can't be opened (or copied to the hard drive) when I put the DVD in a pc, despite seeing what's on the DVD in the directory. Properties show they are HFS+ only, NOT HFS Plus/ISO 9660 hybrid format as suggested here:
http://docs.info.apple.com/article.h.../en/mh854.html

Since my clients use PC's this is really annoying.

It is a Matshita DVD-R UJ846
DVD write: -R -RW +r +RW +R DL

It has never been able to burn disks readable on a pc, but all the documentation says it should. When I burn it in the mac a dialogue box even flashes up saying the DVD will be readable on both formats.

Thanks,
Ash

Just to be absolutely clear, I am NOT creating DVD's, just trying to burn data disks - with ANY type of data. In this case it's Quicktime (DV-PAL) files.

Thanks again,
Ashley

Have you tested one of these discs on your Mac? Could you transfer or access the QT files without hassle?

I have a DVD +R which has the format of Mac OS Extended FWIW ...

Aah, thank you Ashe. Much clearer now. There's something about burning incompatibility between Mac and Win covered in another forum. It's over my head in terms of the technical know-how, but I remember seeing the discussion here: http://forums.macosxhints.com/. I wish I could help you more with the specific thread, but it was perhaps two to three months ago that I read it.

Further, there are a lot of posts about the Matshita brand of burner - and it is not good reading. As I suggested in my previous post, there may be a technical problem with the Mac burner. Are you in a position to try out a different one - external? If so, may I both suggest and recommend a Pioneer. The 115D or 116D (or 215D/216D if SATA) will deal admirably with what you're doing.

Third, what software are your Win clients using to try and read the dvds? I have come across several comments about using VLC to view Mac-burned Quicktime files (and possibly vice-versa). Again, it's a cross-platform compatibility issue, something to do with the way the two different systems burn disks. Not in my realm of understanding unfortunately.

I can open and transfer the disks on the no problem. It's really frustrating that everything says they should be readable on a PC!

You know what Hugh and Vurtual Tracy - VLC does play the files on my PC! (My PC is NTFS formatted). So unless I can ask my clients to install VLC and use the stream/save option to save it to their pc hard disk I'll just continue burning the disks with my PC it's much simpler but just adds an extra task for me each time.

Oh well. If anyone knows and other simple tweaks

Mystifying. Apple just say that ox 10.3 onwards writes disks that can be read on both mac and PC, nothing at all can be found about this issue.

Many thanks for your feedback,
Ashe
