G5 does not see my new HDD

by inbryomusic / June 22, 2013 10:30 PM PDT

Hello everyone

I have a early 2005 Power Mac G5, my current Maxtor HD crashed so i decide to replace it with a 320GB Western Digital Blue and it does not show up on the boot menu.

I've tried to change the settings on the new HDD with jumper on all the combinations and in both bays and still does not show on boot menu.
the weird thing is my old HDD does show on boot with the circular arrow and the right pointing arrow

the issue with old HDD is "Runtime corruption" ive read that if you reinstall a fresh copy of the OS X it wipes everything out and will restore or solve the issue, i've tried that but i put my copy of OS X and few seconds later the optical drive spit it out like it does not read it..

Any ideas???? anyone??

Just asking:
- Is this new hard drive already partitioned?
- What file system does/do the partition(s) have?

If there is no partition on it, Finder won't see it indeed. And since most disks are meant for Windows, it's possible they already put an NTFS partition on it. That won't show in Finder either.

I don't know nothing of Macs, alas, but in Windows we use Disc Management in such a case to view and manager partitions on the disk and format them. I think the equivalent program in Mac OS X is Disk Utility, but that's just a guess. might be useful also.

As stated, that disk has to be initialized (formatted)

before the system can "see" it.

The only way to do this, given that this G5 only has the one drive installed, is to use Disk Utility from the OS X installation disk.
There are a number of third party options but all of those require money and a working Optical Drive.

Put the jumpers back on the new drive to configure it as Cable Select (CS)
Put the OS X installation disk into the machine and shut it down.
Start up holding down the "C" key. Keep it down until you see the spinning gear.
With any luck, the system will boot from the DVD.
Second option is to repeat that process but this time hold down the Option key. You should get a choice of disks to boot from. Choose the DVD and go from there.

Once booted, step S L O W L Y through the installer until the Menu Bar appears at the top of the screen.
Choose the Disk Utility from the Utilities menu. If you do not see the Utilities menu, look in every menu option for the Disk Utility.
Initialize the drive as Mac OS X (Extended).
When done, exit out of Disk Utility, Quit the installer and reboot while holding down the Option or C key. (Whichever one worked for you last time)
Install OS X, and then run your Time Machine backup to bring everything back as it was before the crash

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
