Q: one 250 GB firewire hard drive shows up on desktop as two 250 GB harddrives...

I had a brand new blank 250 GB seagate hard drive installed in a firewire enclosure.

 

When the person formated that harddrive somehow he ended up with two hard drive icons on the desktop each being 250 GB.

 

Can't figure out how that happened and NOW how do we get only one hard drive icon showing up on the desktop with the 250 GB capacity.

 

I can;t figure out how to use Disk Utility to solve this problem.

 

Help please, please, please.

    Please post the specific model number and vendor for the drive enclosure; that'll lead to the specifications, and that can help determine whether this device is one 250 GB drive with something weird, two separate 250 drives, or two separate partitions on one single 500 GB drive, or something else entirely.

    OK, so this is home-grown hand-built stuff, and formatted by somebody else.

     

    Are the two desktop icons identical, or does one have an arrow overlaid?  (If so, that could be what's called a link; an alias.)

     

    Also select with the cursor and then press ⌘I (or select Get Info from the alternate-click popup) on each of the two icons, and determine if the results identical, or if they differ.

     

    Also rccharles' request, as well — that'll indicate whether there's a second disk or a second partition around somewhere else that's the same size, or something that's odd about the current device.

    MrHoffman:

     

    I'll answer this one first because I'm not very good working with the Terminal ( of death ) however I will try as instructed by rccharles.

     

    Both firewire icons are identical with no arrow overlaid.

     

    When I Get Info about both the General info is exactly the same for both. The "name & extemsion" is barely visible and can't be modified. The  sharing & permissions is Read & Write for my name and staff but Read only for everyone.  When i unlock the lock i can't change anything.  Too bad this forum does not allow uploads of images.

     

    Now I'm going to try rrcharles suggestions even though I am really lost working with terminal. However his step by step instructions with screen shots look very easy and give me confidance i can do that.

    rccharles,


    Still working up the courage to go Terminal.

     

    When I went to Disk Utilites both hard drives show up the left pain view.  Then selecting " Partion " for any of both drives tells me in the right pain view : " This partion can't be modified. "

     


    Well poor old MR MAGOO here is devistated. A weekend lost and all his planned work on Final Cut Pro and Logic Pron on hold.

    Looks to me if you have four disks of these sizes disk 1tb, 250.1gb, 250.1gb, 1tb, 320.1gb.

     

    What do you think you have?

     

    Could you put some data on one of the 250.1 disks and see if it appears on the other?

     

    Do you have two 1tb disks?

     

    I guess we should look at system profiler and try to figure out how the disks are connected to the system.  I'll post another message about this.

     

    You can post images.

    By chance,  could you have both a usb and firewire connection to the device.  You should have only one.  Firewire is preferrable.

    I have my  main startup hard drive "Macintosh HD" (one TB) running Maverick, a 320 GB "storage" hard drive, a "Audio Plus" ( one TB ) hard drive running Maverick, and then the 250 GB Seagate with it's shadow. Therefor Terminal is showing 5 hard drives where in reality there are only 4 and they are firewired hard drives connected via Belkin FireWire 6 port powered hub.   NO USB connection and NO daisy chaining.

     

    These are the 4 hard drives showing up as 5 hard drives.

    Shut down.  Using just your (presumably) internal boot disk, disconnect everything else on the USB other than the problem drive — USB hubs and all — and boot.

    The enclosure maybe bad.  Detach the firewire cable and try usb.  Reboot. See if you get one or two drives.

     

    You could try resetting the firmware. These PPC computers where made before 2006.

    Sometimes if volumes don't appear in Startup Manager (what you get when you hold down the Option key at startup), you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime.

     

    Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

     

    reset-nvram

    set-defaults

    reset-all

     

    "The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

    http://support.apple.com/kb/TS1812?viewlocale=en_US

     

    Should the fail...

    Try taking the battery out for 10 minutes.  Put battery back in.  Cross fingers. Power the machine back on.

    --------------------------------------------------------------

     

     

    Did you say what computer you have this attached to?  Could try another machine.  Could try windows box.

     

    Sometimes the supporting fireware hardware doesn't suppor the mac as well as windows.

     

    I recommend you do a google search on any external harddrive you are looking at.

     

    I bought a low cost external drive enclosure. When I started having trouble with it, I did a google search and found a lot of complaints about the drive enclosure. I ended up buying a new drive enclosure. On my second go around, I decided to buy a drive enclosure with a good history of working with Macs. The chip set seems to be the key ingredient for firewire support on mac computers made before 2006 . The Oxford line of chips seems to be good. I got the Oxford 911.

     

    I've bought two external drive from OWC which I have not had problems with.  The cheap ebay external drive gave up the ghost.

      

    I'd give OWC a call. 1-815-338-8685.

     

    Well the system seems to think that two drives of size 250.1 are attached.

     

    /dev/disk1

    /dev/disk2

    This indicates two disks.

     

    Partitions are this way:

      disk1s1

    The s indicates a partition.  In this case partition 1 on disk1.

       2:                  Apple_HFS Untitled                249.7 GB   disk2s2

     

    I do not know why this is occuring.

    Good suggesstion. NO luck. Same old problem. Looks like I will have to hunt down my dear old friend and have him reformat the hard drive. There is a small cd disk included in the packaging however there's no way that i will push that disk into my CD/DVD slot of my iMac. Must be a PC thingy that plays those disks which i don't have.

    There's no need for installing software to access a USB or FireWire disk on OS X, and I'd generally avoid installing add-on software as some of that has historically caused weird problems, and tends to add stuff you don't need, and may not want.
