Mounting CDROM issue
I'm having a hard time mounting my cdrom drive. Here are some details:
Code:
> dmesg cd0 at scsibus0 targ 0 lun 0: <HL-DT-ST, DVDRW GS23N, SB07> ATAPI 5/cdrom removable cd0(pciide0:1:0): using PIO mode 4, Ultra-DMA mode 6 Code:
> disklabel cd0 type: ATAPI disk: ATAPI CD-ROM label: fictitious flags: bytes/sector: 2048 sectors/track: 100 tracks/cylinder: 1 sectors/cylinder: 100 cylinders: 25189 total sectors: 2518848 rpm: 300 interleave: 1 boundstart: 0 boundend: 2518848 drivedata: 0 16 partitions: # size offset fstype c: 2518848 0 unused # Code:
> mkdir /cdrom > mount_cd9660 /dev/cd0a /cdrom mount_cd9660: /dev/cd0a on /cdrom: Device not configured Any suggestions welcome! |

Interesting. Yes, there is a disk in the drive. This is actually on a new MacBookPro (Core i7, 17"), and the disk that's in the drive is the OSX Installation Disk 1. Have to hand this machine off to a colleague, and am a bit stuck at the moment as I can't even re-install OSX for them

It's possible that the filesystem is not ISO9660, I'm not sure what OS X uses on their installation CD's.
Can you try mount -t udf /dev/cd0c /cdrom, make sure /cdrom exists, UDF is common on DVD disks, and might work. BTW, what could possibly be on the OS X disk that you need to access from OpenBSD? to reinstall OS X you would just boot from the DVD. |

Although I don't know definitively either, I have the suspicion BSDfan666 is correct.
Being slightly different from the standard is a deterrent from copying which would cut into sales. Commercial companies don't like sales figures to go down. This puts upper management into finger-pointing mode which has proven over time to be detrimental to the continued employment of those lower on the org chart. Microsoft does the same thing. As for mounting random CD's to see what was on them, trying a commercial install disc was perhaps the worst choice. |

Code:
> mount_udf /dev/cd0c /cdrom mount_udf: mount: Invalid argument > mount_udf /dev/cd0a /cdrom mount_udf: mount: Device not configured 1. Holding down "Option" on boot. This brings me to a screen which shows me a "Install DVD", which when I click, the CD drive starts churning and then dies down to a low hum. The screen just sits there with a big Apple logo on it :/ 2. Holding down "Option + Command + Shift + Delete". This starts spinning up the CD drive, then ends up going right back into OpenBSD. 3. Holding down the "C" key. This also starts spinning up the CD drive, then ends up going right back into OpenBSD as well. After searching around through all my disks, I found another install DVD, this one being the "Snow Leopard" install disk. Code:
> disklabel cd0 ..... 16 partitions: # size offset fstype a: 3794608 0 ISO9660 c: 3794608 0 ISO9660 # /cdrom # > mount_cd9660 /dev/cd0c /cdrom > Code:
> ls /cdrom Boot Camp DVDCDSharing Read Me.rtf autorun.inf setup.exe So it seems like it is indeed ISO9660, but ocicat is probably right when he brings up the fact that these are commercial install disks which probably come with commercial caveats of some sort. Well... close but no cigar... albeit, educational! I need to do two things: 1. Find a way to get OSX back on this machine using a different method. 2. Find a laptop that comes packed with open hardware and drivers. Any suggestions welcome again. Thanks to the both of you for your help thus far. |
