Hi There,


I am trying to format a 3 TB internal harddrive, so that I can reinstal Final Cut Pro 4 on to this new drive, in order to continue editting video. My last hard drive crashed and I was unable to pull anything off of it, so I am starting from scratch. I did have two hard drives, one died and the other one is where all my applications were stored. The 2nd drive is still good, but I running out of space for my video files, hence the reason for this newest drive.


I am working off of a Mac Pro G5 and I believe I was running the OS X 10.4 software. I have the start up disk to install it on my new drive. However, when I try to format the drive, my computer stops working and my mouse pointer begins to spin a rainbow ball and then I end up having to quit disk utility. I am half afraid, I will eventually make the new drive non-operational. So I need a little help.


My questions are these as follows:


When I try to format the 3 TB hard drive, should I consider partitioning it?   What is the up scale to partitioning a hard drive? What is the downfall of that option?

Also, I am able to verify the disk, however the disk shows up as untitled and it only shows up as 746.4 GB, where as I thought it should show up as 2.7 TB. Am I doing something wrong?


I would greatly appreciate some help in this.




PowerMac, Mac OS X (10.4)

    Hi, we need to know if it's a G5, or a Mac Pro, they look similar, but the Mac Pro has two Optical slots on the front.


    G5s are limited to 2.2 TB using HFS+, can format it GUID, but cannot boot from it.


    At the Apple Icon at top left>About this Mac.


    Then click on More Info>Hardware and report this upto *but not including the Serial#*...


    Hardware Overview:


    Machine Name: Power Mac G5 Quad

    Machine Model: PowerMac11,2

    CPU Type: PowerPC G5 (1.1)

    Number Of CPUs: 4

    CPU Speed: 2.5 GHz

    L2 Cache (per CPU): 1 MB

    Memory: 10 GB

    Bus Speed: 1.25 GHz

    Boot ROM Version: 5.2.7f1

    I can definitely confirm that a 3TB drive will not work with a ppc G5 imac, no matter what you do. Unless perhaps, attached as an external, firewire connected drive for backup & storage.  2TB is max for an internal hard drive on the ppc G5 imac anyway. technical interface/communication/recognition reasons.


    To find compatible drives I recommend looking at the OtherWorldComputing.com / aka macsales.com site's upgrade your mac feature it starts at http://eshop.macsales.com/MyOWC/    don't know if apple store has this or not, but they're usually more expensive anyway than OWC/macsales who have reasonable prices and excellent customer service.


    It will analyze and tell you what kinds of drives will go with the specific Mac Pro G5 you have ( I really doubt it can handle 3TB if it is a ppc + running 10.4.x).


    They're a great company, you can talk to them by chat/phone to verify and ask questions. Highly recommended. be sure to sign up for their email list / search for their 'subscriber specials' to get the best deals/prices, slight discounts if you're a subscriber.


    Ask them about a dock to use with your 3TB drive as a back up drive so it won't go to waste.


    good luck!

    There are also 2TB drives to check out at Amazon http://amzn.to/YrnTSP after you've confirmed your upgrade paths.


    Personally I don't recommend seagate at all (read the thread discussion at amazon specifically about 2TB Seagate drives).


    Whatever you go with, and even if you buy from OWC/macsales, I'd recommend reading thru reviews/comments on their recommended specific drives at amazon and find reviews & comments by those especially who are mac users, those who do video editing, and especially the geeks who know technical stuff about these drives.


    There can be lots of great details and tech notes in there, such as: make sure on a 2TB drive, you get one with only 2 platters, not three and find the ones NOT made in china, especially if you do go w/ a seagate despite my warnings.


    I doubt you want a 'green' drive such as the WD green drives for video editing due to speed variability. I think this is what you want http://amzn.to/10QOYiQ the black caviar; it also has a five year warranty -- the quality on so many hard drives has gone down the tubes during the past decade, as evidenced by their shorter and shorter warranties. I have had 3 seagates do complete bricks -- seagates have become increasingly worthless & dangerously undependable over past 5 years imho.



    hope this is useful to others too.

    BDAqua -


    Here is what you asked for:


    Machine Model:               Power Mac G5

    CPU Type:                      PowerPC 970 (2.2)

    Number of CPUs:             2

    CPU Speed:                    2 GHz

    L2 Cache (per CPU):        512 KB

    Memory:                          1.5 GB

    Bus Speed:                      1 GHz

    Boot ROM Version:           5.0.7f0


    Thanks for your help. I greatly appreciate it. I also wanted to state that I thought I was running OS X 10.4, but in fact I was running Mac OS X 10.3.9, so I am thinking I am going to need to do some major updating.


    All I want to do is find another hard drive that I can format and use mainly for my footage, as well as run Final Cut Pro off of it.Is that possible?

    Hi 1VOD,


    Thanks for your help. Forgive me, I have no idea what a ppc imac is... is that the same thing as a PowerMac G5?

    Thanks for the sugguest of the OWC website. Their prices are excellent. I will definitely look into chatting with a technical rep from there.  Also, why should I only get a harddrive with only 2 platters not three. What does a platter do exactly? I was asking my computer IT person at work about the platters and she had no idea.  Granted she only works on PC, but I wasn't sure if that would matter or not.


    Thanks for your help. I'd appreciate it if you could explain a little more.

    PPC Macs are ones with Motorola or IBM CPUs, like G3s, G4s, & G5s, IntelMacs have Intel CPUs, like Core Solo, Core Duo, Core 2 Duo, I3, i5, or i7.

    Thanks BDAqua.


    So I was able to format the 3TB hard drive, but it only formated it as 736GB instead of the 3000GB.  Is that normal? Or should I just consider getting a 1TB hard drive. I don't want to waste the 3TB drive, if I don't have to.


    Could I use a Dock like 1VOD recommended?


    Thanks for your help.

    Oh, only 10.4.11 & up can see the new Adavanced Format Drives properlly, they now have 4096 Byte Sectors instead of the old 512 Byte sectors, so that explains the shortage there.


    The Highest you can go is 10.5.8


    Leopard requirements/10.5.x...


        *  Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor


    minimum system requirements


        * 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)

        * DVD drive for installation

        * 9GB of available disk space (I say 30GB at least)

    Classic/OS9 Apps no longer supported.

    Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...


    You have to call Apple & likely ask for a Product Specialist to get it, if they still have it! Helps to tell them you have an iPad/iPhone & you can't run 10.6.


    There are workarounds if the 867MHz CPU is the only hangup...
