Allows Your Mac to Utilize Hard Drives Larger than 137 GB.
on June 2, 2005
I own a 2001 Quicksilver G4 (OS X 10.4.1) that came with an 80 GB Western Digital Hard Drive. I do film work, so I need lots of space. I purchased a Seagate 300 GB Serial ATA Internal Hard Drive and this card (Sonnet's Tempo Serial 2-Port ATA PCI Adapter Card) was required for my Mac to read all 300 GBs.
Do you need this card?
First, check this website out:
If your computer is a 2002 Quicksilver or newer, then your computer is equipped with 48-bit addressing and you do NOT need this card. Your computer can read hard drives larger than 137 GB.
If your computer is a 2001 Quicksilver(like mine) or older, then you DO need this card in order for your computer to use hard drives larger than 137 GB.
REMEMBER! IF your computer was built with a Western Digital Hard Drive initially, and you want to add a second hard drive, you must switch the Western Digital to the MASTER Hard Drive and your other hard drive to the SLAVE. More info on that here:
