Q: PPC PowerMac G5 doesn't detect SSD drive at boot start

Hello,

I just come back with another question to all of you guys who are always helpful.

 

I wanted to replace my hard drive to a faster one, SSD. The drive is MICRON 128Gb. When I plug it in as a secondary drive, MacOSX Leopard 10.5.8 sees it after  system reboots. But when I want to start from the drive and install fresh Mac OSX, computer while booting doesn't see the SSD Drive. I have formatted the drive of course with the mac format Apple Partition Map (because  I use PPC G5 procerssor). I must also say that so far I am using another SSD drive from Intel but smaller, 74 Gb and have the system succesfully installed and computer work great with that drive. But the Micron is kinda stubborn to work with my Mac. Maybe I still do something wrong way.

 

The Micron  hard drive works fine under Windows 7 and 8.

 

THX

PowerMac, Mac OS X (10.5.8), PPC g5 dual 2.0 7.5GB of ram

    Is the new SSD SATA 1.5 Gb/s compatible?

    My appologee for no response a while.

    I experienced internet connection problems recently.

    So anyway I don't know if the drive is compatible but I've found this:

     

    https://www.micron.com/~/media/documents/products/product-flyer/brief_c400_ssd.p df.


    and my drive is in the chart. This is the one with part number: MTFDDAC128MAM-1J1


    I haven't found any information about compatibility though.

    I am using the drive just for now as the external hard drive for files.

    I can't find any real info either, SATA3 Drives are supposed to be SATA1 & 2 compatible, but in practice I've seen different, especially on G5s implentation of SATA1.

     

    Ah, wait, that PDF tells me the problem...

     

    Compatibility

    • C400 SSDs are backward-compatible to SATA 3 Gb/s, making them easy-to-adopt, drop-in HDD replacements.

    So, you either need a real SATA 1.5 Gb/s drive in slot 0 & this one in slot 1, or a real SATA 1 compatible SSD...

    And, it may or may not work with a SATA 1 drive in slot Zero.

    Hi,

    I don't have much knowledge on this topic, but from what I've read (I'm looking to perform an SSD upgrade to my PowerMac G5) only some SSD's actually work with the G5. I know for a fact that the OWC Mercury Electra 3G SSD with adapter works with a G5, however other SSD brands I am not so sure. Also, SATA 3 SSD's do not work with any PowerMac G5 system, despite the industry standard backwards compatibility. Something to do with the drive controllers.

    I would suggest to try using it in different drive bays, however if this SSD is SATA 3 I do not believe it will work on the G5 system.
