My powerbooks HD just crashed. Therefore I found a rescue program called "SPMAC-Boot DVD.dmg". But each experiment with this "mac-image", ends up with the same "no boot at all" (I press the c-button at start). I have tried almost all the available programs for Windows, but without success. I must do something fundamentally wrong. My method is as follows: convert dmg-file to iso or just add the dmg file(if the program can read that) and then burn the CD with a burning program etc. PowerIso. When I explore the cd with HFSExplore, all looks as it should be. I need a very god advice!?

    DMG files cannot be used with any OS other than Mac OS. I suggest you post your question in the OS X forums.

    Do you not keep regular backups?
  • Tommy Lund1 Level 1 (35 points)
    I wil not use any dmg file under windows - I will just unpack it, only to boot and repair (backup) my crashed mac. No, I need resolved this, because I have no backup at all ( and I know, this is wrong).

    I dl DMG on Windows all the time.

    What I would recommend for you:

    don't use or touch the mac hard drive at all for now
    can you pull it and put it in USB case
    do you have spare drives? one for a new system, one for recovery?
    install Mac OS on a new drive.
    demo of Data Rescue II from Prosoft to see what it can recover ($99 if you decide to let it work)

    Start 'building' a new Mac OS foundation

    I have data rescue 3, but I still need to burn it (as at boot cd).

    So my problem is, how can I burn this (dmg-file) from at windows machine?
  • The hatter Level 9 (60,930 points)
    Can you not hook up an external drive to the dead Mac, and install a fresh copy of OS X?

    As I tried to lay out, build a new solid foundation - on the Mac.

    I have never googled for DMG on Windows.
  • Tommy Lund1 Level 1 (35 points)
    I don't have at external drive (HD).But as I have read, is it not so easy:

    "You need to boot off of a Firewire drive, formatted in HFS+, with the partition map set to "Apple Partition Map" vs. "GUID" which is for Intel Macs only."

    what is meant by "partition map set to "Apple Partition Map" - I dont know.
  • The hatter Level 9 (60,930 points)
    It is easy. Mac OS X won't install to the old PPC PowerMac map.

    Intel Macs uses GPT or as Apple says, GUID, which is the default. It is the underlying format of the drive.

    Intel Macs can boot off USB.

    Thinking backups are strange or difficult, or not needed? No. Luckily I guess Apple Mac OS has TimeMachine which is one step in the right direction but not enough.

    Just install OS X to an external USB drive. You are going to need drives no matter what to get back on your system's feet, to boot and work from, and to recover to (it is possible to get by with a partitioned hard drive).

    The pdf guide for #1 cloning utility for Mac is SuperDuper. But even Apple Disk Utility (Restore tab) is doable, and there are those HELP menu and tips, instructions - and online.

    And if you want to backup and manage PCs and Macs, then something like HP Media Server using Windows Home Server PP3 which supports SuperDuper, TimeMachine, iTunes, as well as for Windows backup and recovery, is top notch.

    Remember, it is at Powerbook 15"

    I have now tried to boot with Stella Phonix and Data Rescue 3: just with same result - that the hard drive can not be found. when such programs are unable to find the hard drive, it may be a hardware problem?
  • The hatter Level 9 (60,930 points)
    Every post I have seen in this forum area is related to other topics associated with Windows on Mac, which require newer Intel based Macs.

    Yes it is hardware, and pulling the drive to put in a case you already did?

    You installed a Mac OS on another drive?

    For $500 there is a disk sector copier than will take a drive (no OS) and just remaster it to another drive. Maybe you can find a recovery company. And then always have two backup sets.
  • Tommy Lund1 Level 1 (35 points)

    No no.

    What do you mean? with? "pulling the drive to put in a case you already did?"

    I do not think there is a reason to start the "Mac OS" on an external drive, because if "Data rescue 3" fail to do that, so will "Mac os" probably also do that?

    But, if the hard drive is damaged in the mechanical parts, then "Data Rescue 3" probably still will be able to find the drive. Contrast, if it is an interface problem, so could the hard drive maybe just be moved (to a different interface).
  • amgqmp1 Level 4 (1,665 points)
    To speak for "The Hatter", he was trying to discern if you followed his earlier advice of removing the hard drive from your PowerBook, and put it in an external drive enclosure.

    Whether or not the logic board or the platters have failed on your hard drive, is probably not germane at this point. The best advice any of us can give (and The Hatter already has) is to use a data recovery firm.

    Finally, I know of no way to burn a DMG to a bootable disc with Windows. You can burn ISO files, so if you're still trying to crack that issue, I would suggest you look for:

    ISO Buster or DMG2ISO

    Sorry about the failed hard drive, and best of luck with the data recovery!

    Thank you!

    The product I've seen work its magic is Diskology's Disk Jockey

    OWC carries their products and there is $280
    (a friend used this with good results)
  • Tommy Lund1 Level 1 (35 points)
    I have found out that it is very easy to burn a mac cd from a Windows PC - just convert the DMG to ISO, and then burn it (with some burn tool).

    Yes, I may try it on another Mac ..

    With respect to a hard drive firm, then it is too expensive in Denmark, it would cost between $ 1000 and $ 2000 - if it is an electronic or mechanical error.

    I want to say thanks for the help.
