Q: Is there a max SATA disk size in OSX 10.4.11 and G4/1.25?

Hello,

 

I am trying to set up a G4/1.25 (2 gig in memory) as a fileserver with a SATA card and 2 x 3 TB seagate disks. This is the setup:

http://eshop.macsales.com/item/Seagate/ST3000DM001/

 

The system is OSX 10.4.11. I am unable to initialize the disks in disk utility. The process starts but then halts and says that it can not continue.

 

My question is if there is a max disk size in OSX 10.4.11?

 

Any help greatly appriceated.

 

Best regards,

Ingolfur Bruun

A:

It is that up to 2.2 TB per drive is viable.

Limits of the partition mapping and (sometimes) controllers are the issue.

 

If the drives are formatted with the GUID partitioning scheme instead of the Apple Partition Mapping scheme, greater than 2.2 TB can be used in OS X.

 

One issue of using GUID partitioned drives in a PPC machine is that they are not bootable.

    Hello again,

     

    I tried to work my way around armed with your input and succeeded

     

    By using a FireWire dock I was able to see the disks in 10.4.11. What I did was to partition the disks with ONE partition in Disk Utility and then format with GUID partitioning scheme instead of the Apple Partition Mapping scheme which I had done before. And as I am using a ATA disk as a startup disk it dosen't matter if the 3 TB disks are not bootable. They will only be used for data, not as system disks.

     

    You saved my day! Thanks again.

     

    Best regards,
