Power Mac G5 - Can't see new hard drive, just installed

by trublood00800 - 8/21/09 9:24 AM

I have a (2005) Mac G5 and I just installed a new Western General 1Tb hard drive (SATA 7200 3.5) in it, I was running Tiger OS prior to the hard drive going bad. When I boot using the OS disk and pull up disk utility, I can't see the new hard drive so I can mount. Before I bought the new hard drive, I had the machine tested @ the genius bar and they assured me my h/d went bad and everything else was functioning ok. Is there a step I'm missing? Any help would be appreciated.

I found out that the firmware on late 2004 G5 models don't support drives larger than 250G.

I have a dual processor G5 ordered 2003 and it is now supporting a 1TB drive in bay. I think perhaps you might check that you are getting power to drive. There are two connections to drive. One is the power. Other is data.

Hey Blutic, How do you confirm the power is up on the power connector?

It should become active as soon as power is connected. How did it go? It should showup on the desktop as the primary drive does. Then you can format it.

drives that require formatting do not show up on the desktop until they have been initialized.

there will be no power on the drive power cord until the ON button is pushed.

With the cover removed, you should be able to hear the drive spin up.

Correct me on this if I am incorrect, but drive should show up under menu-Apple > about this mac> more info>serial-ATA Then format drive from startup with system disk?

Yep, it should show up there

but to do that with this particular drive, you would have to be booted from another drive anyway.

Power Mac g5 limited to 150 MB/sec

In Reply to: Power Mac G5 - Can't see new hard drive, just installed by trublood00800

I had the same issue when I installed a Western Digital Caviar Black WD1002FAEX (1TB) on my wife's Power Mac G5. Turns out that the G5 can only handle a SATA rate of 150 MB/sec. The WD1002FAEX has that rate disabled by default, therefore it can't be seen unless you enable the 150 MB/sec rate on the disk. One does this by jumpering pins 5-6. After I did that, the G5 saw the disk and handled it just fine. No firmware update required.

Biggest problem I had was that the bare drive came with no jumpers, and I had a heck of a time finding a jumper that was the right size for this drive (most of the ones in my junk box were too loose and just fell off).

Solved! Western Digital Caviar Black in PowerMac G5

THANK YOU! Who would have thought that the new drive wouldn't "auto-fallback" to the 150MB/s rate.... jumpering these pins got me up and running. Thanks again

Jumping my 1TB Caviar Black worked perfectly. My G5 started up with no problems. Thank you for the help.

Where did you end up getting the correct jumpers for the WD1002FAEX? I have the same issue. Almost returned it until I saw this posting. Thx!

Computer shops, amazon, etc. It's a dime part but you pay more if you don't head to a shop and ask for one.
