Wine CD-ROM on Mac OS X

Post by jdratlif »

Can Wine access DVD-RW devices natively on Mac OS X like it can on Linux? I was using Wine in Linux to run ImgBurn and it worked great, but I recently switched to Snow Leopard and I don't know how to configure this.

I tried adding the Volume that was mounted by Finder. I tried adding /dev/disk2. Neither worked.

I really like ImgBurn and do not want to abandon it if possible. Thanks.

Raw (scsi) device access like on Linux is not possible on OSX at this point. This breaks cd burning programs and prevents some copy protections from working. There have been topics about this on the wine-devel list (there was a discussion last week).

I've never had a problem.. it mounts the drives in /Volumes

what exactly did you do and what happened when you tried it?

Check the device mount point for proper permissions. You, the user need
to have read/write or your group needs read/write. Otherwise, any
attempt to write to the device will fail.

Not yet, but I'm working on it.

What about read-only access? Does it only work if they access it like a hard drive, not like a cd-rom?

ImgBurn for example doesn't seem to acknowledge that I have a DVD in the drive. Yet I can browse to it in "Browse Folder".

It doesn't seem any "native-like" cd access is possible. Is this correct?

Thanks

You can 'browse' to it because the system 'sees' the entire device and
will read/write to it from the folder.

Correct. Wine does not support, yet, raw device access which is what
ImgBurn needs. BTW, is there some reason that you cannot use the Disk
Utilities to create your disks? One nice feature is that your burnt
disks will be readable by both Windows and UNIX systems (to include
Linux systems.)

When I switched to Linux, I tried their image burning programs. k3b and Brasero in particular. Brasero didn't work at all, and k3b had faulty verification. I lost a lot of data I thought was "backed up" because it said the disc burned correctly. I have never had these issues on ImgBurn, so I turned to Wine to use it in Linux. I really hadn't thought about changing this behavior after switching to Mac.

I have not yet used Disk Utility. I am wary about other programs after my Linux experience. I think I will try it though.

Thanks for the help.

You really should try using Time Machine through a DVD. The program
does a verification of data and you can restore your system to a
particular point in time, if needed. I use an external hard drive for
this purpose. Until my employer basically made it illegal to have the
drive on premises, it used to be there.

I don't know if this is an appropriate solution for me. I have several machines all running different systems. Windows XP, Windows 7, Linux, and now Snow Leopard. I need to be able to restore data to any system, not just OS X.

I've just been burning a half-dozen DVD-RWs every 3 months or so.

Don't use the image option if you're backing up data from your hard
disk. Thats purely for burning an ISO image you've downloaded as a
complete disk. An ISO image is a bit-level copy of the entire disk
surface and is treated quite differently from burning a bunch of files
because an ISO image already contains the label, TOC, etc.
k3b and Brasero in particular. Brasero didn't work at all, and k3b

Are you certain that wasn't a dodgy disk? None of the disk burning
programs that I've used verify after writing, so its just not sensible
to delete the material off hard disk until you've tested that at least
some of the files contain what they should and are readable.

Similarly, IMO its false economy to use el cheapo blank disks. I tend to
buy TDK as a matter of course.

Finally, IME its foolish to trust a home-burnt CD as the only copy of
anything you what to keep more than a year or two.

Here's why. While the first music CDs I bought (25 years ago) still play
perfectly, remember they are physically stamped into plastic (like a
vinyl pressing) before being metallised and having the clear outer layer
cast on to seal the delicate stuff in. THIS DOES NOT APPLY TO A DISK
YOU'VE BURNT. All that burning the disk does is modify a layer of dye.
Once the dye fades the disk becomes unreadable. I've had apparently
decent burnt CDs become unreadable after 10 years - and possibly faster
than that because I didn't play those disks all that often. And they
were stored in jewel cases where they are never in direct sunlight or
over a heater. If you just sling a burnt CD onto a sunny windowsill its
usable life could be quite spectacularly short.

But, back to disk burning software: Brasero works for me if I'm burning
an ISO image or making an audio CD. Otherwise I use the Gnome CD/DVD
creator.

If the disc was dodgy, verification should fail, not succeed. Those same DVD-RWs that burned AND verified under k3b failed to verify with ImgBurn. It's just not sensible to assume that a spot check will provide you with an accurate gauge of success. The discs that failed are better than 99% identical to the ISO. A spot check would've been completely useless.

I buy Verbatim, but even the best media can be bad from time to time.

I didn't lose my original copy of the Gutenberg Bible. I lost a little data. It's annoying, not a nuclear meltdown.

Glad it works for you. ImgBurn works for me while verifying discs accurately.
