cdrecord - data does not fit. But it does.

hi there.
I'm writing an ISO I've written several times before, on this particular DVD-RW disc. Now, cdrecord claims that the ISO is too big, and that it does not fit on the DVD. On Windows, it works, no problem.
I've done the long blank process in xcdroast, tried the command line with cdrecord, and still the same.
So, what happened here?

that happened to me once when i upgraded kernel drivers for my cdr drive.

i just mounted the iso and removed some files i didn't need until it worked. sorry i can't offer better advice.

Uh, I'm not going to change the ISO file. It's a Win7 volume copy ISO. (Yes, I have the volume license key).

I need to write it to a DVDRW (as I've done previously) to install on some new machines. This recorder, on this laptop, with this ISO, with this exact DVD-RW worked plenty of times before.

Curiously. On the virtual machine on this laptop, with windows 7, it recorded this iso. on this DVD-RW.

Only cdrecord is being a PITA.

ok, so I managed to write the image to this DVD with cdrecord on another of my machines, with gentoo also..

this is the output

Code: Select all

gentoo rhiakath # cdrecord /mnt/usb/Software/ISOs/Windows\ 7/7600.16385.090713-1255_x86fre_client_en-us_Retail_Ultimate-GRMCULFRER_EN_DVD.iso

So, everything went smoothly...
So, on my laptop, I try the exact image, from the same disk, to the same DVDRW.

This is the result:

Code: Select all

So , please, anyone has any idea why this happens?

searching the forums a bit yields: emerge dvdrtools and/or make sure the kernel has support as per http://fy.chalmers.se/~appro/linux/DVD+RW/

good luck

On the pc I'm writing this I don't have dvd+rw-tools installed, only cdrtools. I don't have packet writing enabled on the kernel.
And I can write this iso to this dvd.

On the laptop, I don't have dvd+rw-tools installed either. I tried enabling packet writing.
Same result. Data does not fit on the cd.

Stupidly, when I mentioned that on windows it works, I meant on the Windows VirtualMachine inside this gentoo installation. So It's not the drive....

How can I check what is the reported free space on a DVD-RW? Maybe the part that reports the free space is bluffing out somewhere?

Any other ideas?
