Powermac G5 SSD?

    I have recently bought a SanDisk SSD 64gb for my Powermac G5 as the HDD noise was irritating, but I am having difficulties getting it to be recognised, or to even be able to boot. Does anyone have any ideas on how to solve this issue?

    Have you checked the jumpers are in the right position?

    I haven't had a G5, but i know they can be picky with certain SATA Speeds and some Drives, i'd check the drive in another machine as well just to check that the actual drive is working.

    you made to re-format the ssd before installing your os right?
    what version of os x are you trying to get onto/working with the ssd?

    do you still have the package to the ssd? check to see if it is sata 3-6.0 gb/s or if it is sata 2-3.0gb/s

    some users were having issues in the imac g5s when using a sata 3 ssd as the sata bus couldnt handle it.
  4. macrumors newbie

    This SSD was brand new so it should be working. Also there are no jumpers. I cannot reformat it as the G5 is the only machine that I have that has SATA! I am trying to install 10.5.8 onto it


    Also, it is a sata 3 drive, but I have heard that they are backwards compatible?

    Not everything that is SATA III can be backwards compatible to the Powermac G5. Best thing is to return it and get a SATA II SSD. Also try to connect it to the lower bay, sometimes teh connections are just picky.
  6. macrumors newbie

    I have tried the lower one, but that does not change anything. I do not want to return it though as I am planning to use the SSD in a computer that I am planning to build this summer and I would like to have a fast SSD for it.

    The G5 sata controller can not agregate link bandwith between the SATA I bus and the SATA III bus.

    Get a SATA card.
    A SATA card would be MUCH faster, and allow for any hard drive.

    If the SSD has jumpers, then set them to SATA I or II mode.

    I learned this the hard way by trying three hard drives in my iMac G5, and then in the PowerMac G5. Once I got my SATA card all of the issues went away.

    Just let him RTV his SATA III drive and replace it with a SATA II, cost less than getting a SATA III interface card which is bootable.

    I missed the OP's response.

    There is no other way but for you to spend more by getting a bootable SATA III interface card.
  9. macrumors newbie

    Why can I get an affordable sata controller from, as the only one I can find for the G5 is about £80, that is more than I paid for the G5 in total!
  10. macrumors 68000


    Look for ones with Silicon Image chips.
  11. macrumors member

    You can format the ssd with the osx install disk, go to utilities and go to disk utility there you can see all of the disks connected
  12. macrumors newbie

    So are you saying that if I format the SSD it would work with the G5?


    So would something like this work if I found the correct drivers for mac?

  13. macrumors 68000


    You cannot format the disk if you cannot mount it. If it is not seen under disk utility it means it was not mounted and cannot be recognized.


    There was a thread here describing the same topic about cheap bootable SATA interface cards with SiL chips. I am not sure but as far as I can remember it doesn't need any drivers at all. I might be wrong though.

    btw, what is your specific powermac?
  14. macrumors newbie

    I might be able to use a friends mac pro to format it, would that work? My specific powermac is the dual 2 GHz 7,3 with 5gb of ram.
  15. macrumors 68000


    It sure can be recognized on a mac pro. Partition it using APM or Apple Partition Map since the MP will partition it using GUID. GUID cannot be used as bootable drive on powermacs. But I doubt it can be recognized on the powermac once you put it back there.

    Thanks i'll try that

    It is sad but true ....
    you need sata 2 ssd

    and sata 2 ssd make difference to my g5 quad

    though it need to repaire permition regularly
  21. macrumors newbie

    I tried to format it, but that had no effect, still a grey screen on boot up. Is it just this specific SSD that will no work on a powermac or sata 3 drives in general? As I am looking into buying a hard drive instead that would sata 3.
  22. macrumors 68000


    It's SATA III drives in general, though I believe that some work.
  23. macrumors newbie

    You don't happen to have any idea of some that work? That would be of great help to me, thanks.
  24. macrumors 68000


    Sorry, I have no idea. Might take a read of this thread, and hope that other people with more experience with SATA IIIs in G5s show up.
  25. macrumors 68000


    SATA II is still your best bet.
