OS X :: Partition External Drive For Both Mac And Windows
Oct 12, 2009
Here's what I want to do. I have a 1.5 Tb external USB drive that I want to use with both my MacBook Pro and my soon-to-be Windows 7 desktop PC. I want to make image backups of both systems onto this external drive. For Windows, I'll use a boot CD with Acronis TruImage. For the Mac, I'll use SuperDuper! I've been playing around with partitioning this drive so that I can accomplish both of these goals and I'm a bit stumped. I was able to get a two partitions created - one for Windows (NTFS) and one for Mac (HFS+), and at first look they appear to work fine. However, there appear to be two problems:
1) When I look at the disk in Windows Disk Administrator, there are two smaller "hidden" partitions that I did not create. I think they were created with the Mac formatted its partition.
2) When I boot my Windows computer with the Acronis TruImage CD (and have the external drive plugged in to USB), the Acronis software doesn't see the external drive. When I boot into Windows, the drive is there and accessible.
So, I can deal with problem #1 if those hidden partitions are necessary for the Mac. However, I really need to resolve problem #2. My initial guess is that it can't see the drive because when I partitioned the drive on the Mac, I did not choose "Master Boot Record", rather, I chose the one for Intel-based Macs.

I currently have XP installed on a Bootcamp partition on my main iMac hard drive. I've got a new external USB 2.0 SATA hard drive enclosure on the way that I plan to install a couple of spare SATA drives into. I was wondering about somehow moving my current Bootcamp partition off the main iMac drive and onto the spare WD Raptor drive that I've got without having to reinstall everything all over again. My second question would be - if I am able to switch the Bootcamp partition location, would the USB 2.0 transfer speed be fast enough for when I run windows? I typically use Windows for gaming only and very little else.

I am trying to format my external drive to have (2) partitions. A NTFS for backing up my Windows computer and a HFS for backing up my MacBook Pro.
This is what ive tried:
1.) Create 2 partitions on my Mac in Disk Utility. 1 partition HFS, 1 partition FAT32. After doing this both show up in OSX but neither one shows up in WinXP. I was hoping the FAT32 would show up in WinXP so I can convert it to NTFS.
2.) Create 2 partitions in WinXP using Disk Management. 1 partition is NTFS and 1 is FAT32. Connected the drive to my MBP and both partitions mounted in Finder. I then opened Disk Utility and tried to "Erase" the FAT32 partition to HFS. The process seemed to be working but then it changed the name of the partition to disk1s1 and nothing else. The partition doesnt mount in Finder or WinXP.
3.) Create 2 partitions in WinXP using Disk Managment. Both partitions as NTFS. Connected to MBP and both partitions mounted in Finder. Opened Disk Utility and tried to "Erase" one of the NTFS systems to HFS. Same thing happen as #2, renamed the partition but didnt do anything else. The partition doesnt show up in Finder or WinXP.

I'm trying to install Windows 7 and can't get the boot camp assistant to partition my drive. The drive in question is 500GB with over 200GB free space. I want a Windows partition of 35-40GB.On first attempt I kept getting the cannot move files error when trying to partition. I read up on the error online, and most people suggested issues with parallels or needing to use idefrag. I had parallels on my machine at one point, but am not sure if there are any problem folders still hiding somewhere. Any tips on that part?I ran idefrag overnight last night. When I booted the machine up this morning, I launched it again to verify that the disk was defraged. Boot camp still doesn't want to play.

So I have an external firewire drive I use for all my Time Machine backups in OS X. It's formatted in the typical Mac journaled format or whatever it is. I have 2 partitions, one with my Time Machine backup. I booted in Windows 7, and intended to reformat the other partition to work with Windows, but it didn't want to let me change that partition, though it did recognize it as an OS X format.

perhaps I am doing something wrong? I wanted to install Windows XP on my iMac. I previously had partitioned my Mac drives. I backed everything on these drives to my external and blew the partitions away creating my one Mac drive again.
I then ran Bootcamp, created a partition and installed XP. Everything was fine. I then partitioned my main drive and got the warning message about Bootcamp maybe not working afterwards. So I finished partitioning my Mac drive as I wanted and now I don't have the option of booting into XP through Bootcamp. When I try it just shows the Mac drive as my only boot option. I see the XP Bootcamp drive in the System Preferences startup disk area, but I assume I did something to the partition once I partitioned my Mac drives

Have a G5 Imac, Intel Macbook and a 1.5 TB external drive for backups. I created 3 partitions on the external for backups for both computers and the extra partition for storage of some rips.. Is it possible to partition the external so that the Imac partition (HFS+?) is bootable and the Macbook partition (GUID) is bootable?
Thanks for any advice..

Recently I bought a Mac OS X Leopard, which comes with the Bootcamp. I have the XP operating disk, and Virtual Box, which is another program like Bootcamp. Instead of the bootcamp way of rebooting every time you switch between operating systems, Virtual Box allows both systems to run simultaneously. Instead of taking up space on my hard drive, I purchased a Seagate FreeAgent (Desk Edition) 1TB external drive.
I need to partition this drive in two, to allow the combined running of PC and Mac OS X using Virtual Box. The formats I will be using are FAT 32 and Mac OS Extended (Journaled). The latter is very easy, as I can simply do this on the Mac. However, the FAT 32... Since I am splitting the external hard drive in two, my XP PC cannot create a partition using FAT 32 which is greater than 32GB, and if I create the F32 partition using the Mac it won't be recognized by the PC operating system.

i as planning to sell my macbook in the near future and i wanted to back up everything to my external hard drive. I heard of offsite backup but i didn't plan on doing it yet. Anyways i used time machine to make my external hard drive to be my backup disk. First i had to take everything off it (80GBs worth of music, movies and documents) and i put it on the desktop cuz Time Machine said something about incompatibility and i had to erase my external drive first. I then backed up at least 120GB of content altogether to the external hard drive. I checked my external drive and found out the stuff i took out and put on the desktop was NOT backed up. So i deleted the backup and put the 80GB of movies, music, etc stuff in a folder in my computer.
However i can't back up to my external drive anymore. It says it only has 61.28GB of memory left. I'm wondering why is that if i deleted the backup already! I then tried to take the backup out of the trash and put it back in the external drive and it won't go in because there is only 62.28GB of memory. I don't see any partition of any sort on my external drive, no folders, files or anything yet it has magically lost 190GB of free storage.

I have a WD 640GB External drive and i would like to partition some for time machine and some for storing my files. i just have some questions:
1) If i partition the drive into 2, in the future can i join the two partitions together again?
2) does the whole external drive have to have the same file system like HFS or NTFS or can one partition be HFS + for time machine and the other partition NTFS to make it readable on windows?

I've got an external 500gb Seagate drive with 2 journalised partitions.....one for my time machine backups and the other for holding audio samples for my drum machines and such. All of a sudden today the audio partition won't mount but the time machine partition still works fine. I go into disk utility and it shows ther but just says unable to mount when I try to mount it. It suggests first aid so I verify and repair numerous times and it says everything is ok. I can boot up Ubuntu in VMware andboth partitions are visible and all the files are there....everything is just as it should be. I was using 10.5.7 and just upgraded to 10.5.8 tonight and nothing changed.

I've done some searching on the forums, but I cannot find exactly what I need. I currently have a Maxtor external hard drive partitioned into two sections; one for time machine, the other for music, movies, etc. Normally, the two separate partitions would show up on my desktop (labeled "Music" and "Time Machine") but as of lately the Time Machine partition fails to show. I cannot find the volume anywhere, but the Music partition still reads perfectly fine. how I can relocated the Time Machine partition?

I have a seperate 1TB internal drive on my mac that I've formatted for XP64. Is there a way to partition that drive with XP on it so I can install Vista too, that way I will have 2 500GB partitions one with XP and the other with Vista? OR will I have to swipe everything and make 2 partitions my first step?

I just ordered a 1 terabyte WD external drive, and I'm planning on creating one partition for music/movie storage, and a second smaller partition for a superduper clone. So my first question is, what format should each partition be in? I'd like the movies/music partition to be Windows compatible...will choosing FAT32 make any difference in my use of this partition when used with my OSX machine, and what benefits would I see by using Extended Journaled instead? Then, what format do I want the Superduper backup partition to be? Finally, when I initially format and partition the external drive, is there anything I should do to prepare it first, or just go right ahead, divide it in two (approx. 650gigs for music/movies, the rest for superduper) and then format each partition on its own into the formats they need to be in? Also, do I use GUID partition format?

I have a 1 TB LaCie drive that I am currently using with a MBR partition scheme. It has two partitions: one for time machine and one for windows. What I want is to use this drive to hold my time machine back ups in one partition for Lion, which I am about to switch to and install on the iMac internal drive, my windows stuff in one partition, and a third partition in which I would put a clone (CCC) of my current internal drive (Snow Leopard) that I could boot from when desired.
This would enable me to run Lion normally from the iMac's internal drive, switch to the windows partition (holding down the option key when powering on) on occasion when I want to work in a windows only app, and using the same option key on power on trick, boot into Snow Leopard when I need to use old, apps that won't run on Lion. For this, I assume that I should use the GUID partition scheme. Am I right? Is there a better way to accomplish my goal?

iMac, Mac OS X (10.6.8)

I am installing XP on my mac laptop and am not sure how much space to partition. The laptop's total space is about 235GB with currently 50GB free.
I will only be using Windows for a few specific programs: Autodesk: Toxik, Mudbox, Motionbuilder and Cleaner XL. I probably won't be using the programs too extensively either, I mainly use Maya and I have the OSX version of that.
Based on that info I was hoping to get a rough estimate on how much space I should partition for XP, I don't want to go too low and not be able to install and use everything but at the same time I don't want to put too much space on the XP partition either and end up with wasted space.

I set up a boot camp Windows partition. Once in Windows, Partition Magic will not work in partitioning the boot camp drive. I tried from Disk Utility in OS X as well and that doesn't even let me partition the drive. Is it not possible to do? I am creating this to try to play a PC game and Fusion won't cut it. I would like to create normal partitions like I always do in Windows if possible.

i'd like to format my lacie external hard drive with two partitions:
1. HFS+ partition as a bootable clone of my internal drive
2. FAT32 partition readable by any windows (and mac) machine
i'm creating my partitions with disk utility, but i hit a snag when choosing a partition scheme...apparently i cannot choose a different scheme for each partition.
so when i format the drive with GUID, the FAT32 partition is not even recognized by windows XP. but when i format the drive with master boot record (MBR), the HFS+ partition is not bootable...

How do you set up, step by step, Time Machine? I want to create a partition on my external HDD (40GB in size, 120GB capacity) and have it back up to that partition. Is it possible? I only use around <30GB so I figure 10GB extra space is more than enough.

I am looking at getting an airport extreme along with an external hard drive. My idea is to use the external hard drive as network storage along with a time machine drive for my MacBook Pro. Is it possible to partition the external drive with one partition being for network storage and the other for time machine?
