Maximum Partition Size for External Drive using DU

Hello,
I just purchased a 750g Maxtor USB drive for use with Time Machine. When I went into DU to partition and format the drive I was surprised to find that every time I went to create a single partition using all available space, the operation would error out. I was however able to create two partitions with the largest one sized around 650g or so. I was using the Mac file system.
This just seems odd to me. Does OS X have a maximum allowable partition size that prevents me from creating one large partition?
Thanks,
Robert

Hi Robert
You should be able to delete the partition, try again using the instruction in the following article:

  • Maximum partition size for external hard drives with G4 MDD?

    I have a Maxtor 300GB external hard drive. When I initially formatted it, I did so with 4 partitions because I knew there was a limit that G4s recognized with internal hard drives. Is that the case with externals as well or can I reformat it to be one large external drive?

    Hi, what G4 model do you have? Only the Quicksilver 2002's and MDD's + MDD FW800's don't suffer from the 128GB capacity. In fact, in any of the above G4s, you can put up to 144 petabytes.

  • What is the maximum partition size for windows on 128GB MBA?

    I want to use Windows 7 as my primary OS on my 128GB MBA. How big can I make my windows partition? Is there anything special I need to do?

    You have two options.
    1. Put OSX on an external drive - OS X: Installing OS X on an external volume - Apple Support and make your internal disk to be fully Windows.
    2. Use minimal OSX size between 16-32G, and the remainder for Windows.

  • Change the partition of an external drive using Disk Utility?

    I wish to change partition scheme, sizes, in an external drive. All the partitions are MacOS extended (Journaled) and they map, according to the layout in Disk Utility, as follows: Partion 1, 2, 3,4 where 1 is at the top and 4, the bottom. I want to make partition 2 larger, so I decreased partition 1 by half. Now the layout is 1 a, 1b, 2,3,4., where 1b is now free space. Disk Utility will not allow me to increase the size of  partition 2 by dragging the corner. Which of the following options (if any) will allow me to increase the size of partition 2, without erasing the data, using Disk Utility:
    Select partition 2 and manually writing a new value in the size box, equal to the present partition’s size plus the free space?
    If I delete partition 1 completely, will I then be able to increase the size of partition 2?
    If I delete partitions 1, 3, and 4, will I then be allowed to increase the size of partion 2?
    Is there another option?
    Thanks
    (Actually, partition 3 is an eDrive, a data recovery utility created by TechTool Pro 7, so I don’t really know how it’s formatted.)

    You cannot re-size the existing partitions in such a way that you can take the space from a shrunken partition and add it to another partition. Disk Utility cannot do that. If you have an existing partition that lives above another partition, then you can delete the lower partition in order to expand the upper partition into the freed up space. This concept applies to any additional partitions that are below another partition. Disk Utility can do this. You can resize down, but not up, except when creating new partitions. You would need third-party software such as iPartition 3.4.3 to accomplish that feat.

  • Using Disk Utility to create a partition on an external drive

    Hi Everyone
    I have a 250gb external HD drive which is currently split into two partitions of Fat32. I'd like to use this drive for storing images of OS X, but when I tried to create an image using the OS X startup DVD, I was told that FAT32 didn't allow large enough file sizes (or something along those lines) in order for me to backup my OS X.
    Disk Utility appears to offer the ability to split partitions on the external drive, i.e. I can select the largest of the two partitions and choose to split it into two 96gb partitions. However, will this be a destructive partition process, and can I reasonably expect my external hard disk to be reformatted with a 96gb Mac OS X formatted partition whilst still keeping two FAT32 partitions and all the data that resides on them?
    Any help is much appreciated!

    You will not be splitting existing partitions. Instead, you will be creating a new partitions from scratch.
    Run Disk Utility. Select the hard drive to be partitioned. Make sure you select the hard drive in the sidebar, not the volume indented below the drive. Go to the Partition tab. If you want one or more of the partitions to be MS-DOS, you must first click on the Options... button. Select the Master Boot Record option and OK. Select Volume Scheme of 3 Partitions. Now set up your three new partitions as you want them, in terms of size and format. For the Mac partition, select Mac OS Extended (Journaled) as the format.

  • Can i have my windows partition on an external drive?

    hello all,
         alright, so im looking at a laptop for college and after much research and a few trips to the apple store i want the new, 13-inch macbook pro, with retina display and a 256GB flash hard drive. i love this computer in every aspect except.... you guessed it, its small hard drive. i can always get external drives to make up the differance though, and their is always the cloud so i dont think ill have too much of a problem. but i do need to use some software for college that is only windows based. so rather then splitting up this already small hard drive can i just install windows onto my mac (because i already know i cant put windows on an external drive with boot camp) and make the entire windows partition on the external drive? this way im not losing any native space besides that used to hold windows and im not installing windows to an external drive so hopefully bootcamp wont have a hissey fit. can anyone tell me if this will work? or if this wont work can anyone give me any other solutions to having windows on my mac without splitting up my native hard drive? such as installing windows to my mac and making the partition in the cloud or something? just anything so i dont have to split my already small, yet extremally fast, 256GB hard drive.

    You can install Windows on your internal drive and store your Windows data on any drive you want to use. Keep in mind that any Windows programs you install in Windows will be installed on your internal drive. So make the Boot Camp partition large enough for Windows and any programs you may install now or in the future. You will also need room for swap/page files and other activities such as installing Windows updates.
    100GB will likely be a good size for the Boot Camp partition given that it is unknown what programs you will be installing.

  • Recommendations for external drive?

    I'm looking for recommendations for an external hard drive to add to my iMac G5, 17" flat panel. I want to have enough GBs to use it as a backup AND to be able to store graphics such as my photos, videos and the like — all the components of making DVD movies. Ideally, I will be able to use the external to transfer things from my computer to other computers.
    My G5 has a 250 GB hard drive. I'd like the external to be large enough to contain things I haven't even thought of yet.
    I'm not that savvy when it comes to the workings of computers, so ease of use/simplicity is paramount.
    All recommendations (and reasons why) will be much appreciated. Thank you.
    ccCarol

    Get a firewire drive and use SuperDuper! to make a clone and then regular backups (it's easy). As far as what make of drive, I have always had good luck with LaCie, and there are others who swear by Maxtor or OWC, which you can find here. In terms of size, get the largest one you can afford, in your case I would think at least 500GB. Transferring your video etc can be done to a second partition on your external drive by simply dragging and dropping the data. Partitioning is straightforward, using Disk Utility.
    Let us know what you decide, hope this has been helpful,

  • Best way to set up partitions on 250GB external drive

    Hi all,
    I've decided to go with an Iomega eGo 250-GB FireWire portable drive to back up my iBook's hard disk (30 GB) plus to store my photos and maybe hold a bootable copy of OS9.
    This is my first time using an external drive, so I don't really know how to go about setting things up.
    What would be the best way to set up the partitions on the external drive?
    1) I know I should create a 30GB partition for the iBook backup, but what about for the remaining volume? Is it best to leave it as a single large 200GB partition, or split it into two 100GB chunks? Other than the clone of my iBook, I'll mainly be storing photos (at the moment no more than around 10-12GB).
    2) I don't yet have a huge iTunes collection, but if I later want to store iTunes music that doesn't fit on my internal drive, is it fine to put it in the same partition as the photos, or would it be preferable to create a separate partition?
    3) If I want to install OS9 on the drive, how much space should I allot to it? Would this enable me to run legacy apps on my iBook?
    4) Does it matter how I name the partitions (i.e. should the name for my iBook back-up be the same as the original volume or should it be different?)
    5) As I still don't know exactly what I need, If today I decide to create only 30GB partition to backup the iBook, can I later partition the remaining space without having to start all over again?
    6) Also, the drive came out of the box with Mac OS Extended format. Is this the best format or is there another that would be better?
    Thanks for any advice

    The answer to both question is that it's completely up to you. Partitioning or not partitioning won't affect operation significantly.
    3) If I want to install OS9 on the drive, how much space should I allot to it? Would this enable me to run legacy apps on my iBook?
    The iBook G4 can not boot from OS 9 so you would only be able to run OS 9 in the "classic" environment.
    4) Does it matter how I name the partitions (i.e. should the name for my iBook back-up be the same as the original volume or should it be different?)
    No
    5) As I still don't know exactly what I need, If today I decide to create only 30GB partition to backup the iBook, can I later partition the remaining space without having to start all over again?
    There are a few tools which promise the ability to change the partitioning without destroying the data on the drive. But you should never do this without making a backup of the data on the drive. Data loss can easily happen and in a big way.
    6) Also, the drive came out of the box with Mac OS Extended format. Is this the best format or is there another that would be better?
    That is the best format.

  • What is an idea of maximum file size for a film in Captivate?

    Hi there,
    I'm creating an elearning course in Captivate 7, and it is being published as HTML5. This means the films I've imported are being converted to MP4s, and they are around 10-20mb in size once they've converted. They seem very slow to load on some computers - do you think the file size is too big? Or could it be another issue? Does anyone have a recommendation for maximum file size for films? They are 572 x 322px and around 1-2 mins in length.
    Thanks in advance

    Probably better guidelines that dictates 'size' of a vi are:
    typically no more than 1 video screen in size
    is it legible
    and is it's function and operation clear.
    I have seen examples of '1 vi does it all' that were many screens wide and tall, totally a flustercuck, and nearly 1 MB in size.
    Globals and local variables (except for LV2 style) are typcially shunned for they can create a host of problems (race conditions, indeterminant data).
    Use connector pane to wire controls and indicators to. Then use wires between vi's to transfer data. I tend to use clusters to hold shared data.

  • Maximum HDD size for Satellite Pro 4290 ??

    My hard disk is wearing out (Win 98 tells me it has many bad sectors). Do I have to fit a 6gig hard disk or can I upgrade? If so, how big a disk will the latest BIOS address?
    I think I need a 2.5" 9.5mm disk, but I don't know if there are any other specifications I have to adhere to.
    ALSO, if I buy a USB hard disk for back-up etc, will the computer see it? Is there a maximum size for external USB disks?
    HELP!!!!

    Hi Mike
    There is no precise information or specification about this issue but I am sure that you can use 10 GB HDD without any problems.
    I have two external HDD`s and I have no problem because I use both with USB 2.0. Your unit has just USB1.1 Maybe you should not use HDD with high capacity. I will try to connect my 30GB external HDD to USB1.1. After that I can report you what exactly happens.

  • Maximum HD size for MDD G4?

    Hi there
    I had a real pain in the proverbial when trying to do a clean install of Panther (or Tiger) on a 1Ghz G4 on a new 200 Gb HD. There were instablilities, Hands on shout down/restarts, etc, before running any updates or 3rd party apps.
    Is there a maximum HD size for these Macs? It came with a 80Gb HD.
    Thanks for any help...

    Some RAM that worked under prior versions of OS X has been known to fail. Tiger makes much more use of all available RAM for cache is part of the reason. Memtest would give it a good workout overnight.
    MDDs support Cable Select, it depends in part on the IDE cable itself. In fact, you could use it on older Macs and controllers most of the time.
    Never apply an update without first doing a backup and some disk repair and maintenance. Even flushing the cache folders with something like Applejack. Never use your Mac while an update is taking place. Reboot prior to applying an update, might want to use Safe Boot Mode. And use the standalone updates, and the combo update if possible. On some occasions it was necessary to reapply the combo update.
    With Tiger, I found that while it was possible to update, a full erase and install resulted in a better OS. So backup.
    If you keep your home directory or backup on another drive, so much the easier and better.

  • Partition size for Leopard

    I am in the process of planning a new internal hard drive for my iMac G5 and am hoping for some advice. It will be a dual boot Tiger/Leopard partitioned 1TB drive (already purchased). I would like to maximize space in my third partition for non-sensitive files (music, photos, 40 hours and growing of home video) while leaving adequate space on the boot partitions to run the OS comfortably.
    Any suggestions for partition sizes for Leopard and Tiger?

    I read yesterday that a new Firewire standard is to be announced in October raising throughput to that seen on eSata drives. So maybe the new crop of external drives that will hit the market will make some of this issue disappear.
    I am about to rebuild my Mac (500gb drive, Intel Core duo) and was thinking only three partitions would be necessary (OS X, BOOTCAMP / WinXP and DATA). I have an external video scratch disk for FCE.
    However I am unsure how to ensure my USR folders are mapped to the DATA partition so that the 50GB is only for OS X and the applications. I have noticed the Library \ Application Support folder can get quite large depending on the apps installed.
    Is there some sort of white paper or thread that gives advice on this?
    Thanks

  • How can I mount a Raid set (partition in an external drive)?

    Hi,
    I have 3 partitions in my external drive. I tried to create a concatenated Raid from 2 of the partitions. However, I end up with an offline Raid Slice (one of the partitions is under this slice) which is grayed out in Disk Utility.
    When I try to delete the Raid Set, I get "Deleting RAID set failed. This RAID configuration is not valid" warning. When I try to erase the RAID volume, I get "Volume Erase failed with the error:The chosen size is not valid for the chosen filesystem." warning. I cannot mount the volume either.
    So, I have 2 of the 3 partitions mounted. The 3rd partition (which is under RAID) is unmounted. Do you have any suggestions to have access to the 3rd partition?
    Thanks.

    Why are you trying to RAID two partitions on the same drive? Aside from the fact that it doesn't work it also makes no sense when you can simply create a larger partition by joining the two into one.
