Create data partition

Hi,
I've just bought a Mac mini and I'm trying to migrate all my stuff from an old Panasonic toughbook. I've created a bootcamp partition (60 GB) and installed Windows 7 pro. I now want to create a data partition and import all my documents from my Panasonic. My question is the following: what kind of partition is best to create? I've noticed that I could format a partition in five different formats:
Mac OS Extended (journaled)
Mac OS Extended (Case-sensitive, Journaled)
MS-DOS (FAT)
ExFAT
Free Space
Which one would be best? I also intend to keep a back up on an external HD. I'd also like to be able to use the files I've previously created on Windows. And, in the future, I'd like to use files created with either Window or Mac with both OS. Would that be possible?
Thanks

Keep Windows files and OS X files in separate partitions.
The Windows partition should be formatted as MS-DOS (FAT), the OS X partition as Mac OS Extended (journaled).

Create data partition and ubuntu partition

I would like to create 2 more partitions on a ThinkPad x230t tablet: one partition for all my files and other partition to install ubuntu OS.
According to Disk Management the computer already has the following partitions:
SYSTEM_DRV Simple, Basic, NTFS, Healthy(System, Active, Primary Partition)
Windows7_OS(C Simple, Basic, NTFS, Healthy(Boot, Page File, Crash Dump, Primary Partition)
Lenovo_Recovery(Q Simple, Basic, NTFS, Healthy(Primary Partition)
I have read that there is a limit to the number of primary partitions allowed and that partition type and placement matter.
Any suggestions on how to proceed are welcome.
Thanks.

- As I read, I guess GRUB makes the recovery button useless? I don't want to lose my licensed Vista, so what can you suggest me to do?
I think it will work. At least if it doesn't you may reinstall Rescue and Recovery.
After shrinking C: drive, it complains about not being able to find winload.exe and does not open
You have to recover the loader. I used a Windows Vista bootable DVD for this purpose.

How to create DB partitioning in active data tables for ods?

hi all,
Can anyone let me know how to create DB partitioning in active data tables for ods. if any docs pls share with me at my email id : [email protected]

Haritha,
The following steps will briefly explain you to improve the performance in terms of DB partitioning as well as loading. Please find the same,

and remove 'bex reporting' setting in ods if that ods not used for reporting.
hope this helps.

Symptom
This note contains recommendations for improving the load performance of ODS objects in Business Information Warehouse Release 3.0B and 3.1 Content.
Other terms
Business Information Warehouse, ODS object, BW, RSCUSTA2, RSADMINA
Solution
To obtain a good load performance for ODS objects, we recommend that you note the following:
1. Activating data in the ODS object
In the Implementation Guide in the BW Customizing, you can implement different settings under Business Information Warehouse -> General BW settings -> Settings for the ODS object that will improve performance when you activate data in the ODS object.
1. Creating SIDs
The creation of SIDs is time-consuming and may be avoided in the following cases:
a) You should not set the indicator for BEx Reporting if you are only using the ODS object as a data store.Otherwise, SIDs are created for all new characteristic values by setting this indicator.
b) If you are using line items (for example, document number, time stamp and so on) as characteristics in the ODS object, you should mark these as 'Attribute only' in the characteristics maintenance.
SIDs are created at the same time if parallel activation is activated (see above).They are then created using the same number of parallel processes as those set for the activation. However:if you specify a server group or a special server in the Customizing, these specifications only apply to activation and not the creation of SIDs.The creation of SIDs runs on the application server on which the batch job is also running.
1. DB partitioning on the table for active data (technical name:
The process of deleting data from the ODS object may be accelerated by partitioning on the database level.Select the characteristic after which you want deletion to occur as a partitioning criterion.For more details on partitioning database tables, see the database documentation (DBMS CD).Partitioning is supported with the following databases:Oracle, DB2/390, Informix.
1. Indexing
Selection criteria should be used for queries on ODS objects.The existing primary index is used if the key fields are specified.As a result, the characteristic that is accessed more frequently should be left justified.If the key fields are only partially specified in the selection criteria (recognizable in the SQL trace), the query runtime may be optimized by creating additional indexes.You can create these secondary indexes in the ODS object maintenance.
1. Loading unique data records
If you only load unique data records (that is, data records with a one-time key combination) into the ODS object, the load performance will improve if you set the 'Unique data record' indicator in the ODS object maintenance.
Hope this helps..

Help! Need to recover lost hard drive data after creating a partition!

So, I'm the world's biggest idiot, and I was trying to reformat my hard drive so that I could bring the documents from my Mac to my PC.
All of the docs were perfectly organized in folders and subfolders a long time ago, and once that had been done, I deleted everything off of the MacBook itself. I never thought I'd have to move all of the docs to a PC, but alas, nothing ever goes the way we plan now does it?
Anyways, I created a FAT 32 partition not realizing it would delete everything I already had on the hard drive, so now I need to recover all of that.
Is there ANY way that I can recover all the data I lost?
Pls respond.

When you create a partition, the partition is the erased so all content is lost. There are data recovery services that may be able to recover the material, but they are very, very expensive, if they can even succeed with this kind of erasure.
Check and see if there are any hard drive data recovery services in your area.

Tutorial - How to triple boot OSX, Linux and Windows 8.1 with a shared Data Partition without any third party Win / OSX softwares

This is not a question, but rather a personal guide that has proved to be running successfully.
I would like to thank numerous sources, including Christopher Murphy's suggestions at:
Re: Repairing Boot Camp after creating new partition
Before proceeding, there are certain concepts needs to know:
Why Boot Camp does NOT allow further partitioning of drives after Windows has installed?
Answer: Because the way Apple configures the Mac to be recognized as non UEFI capable system on Windows.
Quote from Christopher Murphy based on the above line:
However, Windows on Macs right now use CSM-BIOS mode in Mac firmware that presents BIOS to Windows rather than EFI. Windows thinks it's on a BIOS computer, and therefore mandates the use of MBR for boot disks, rather than GPT. So that's why we have this hybrid MBR+GPT approach on Mac with Windows on it. You inherit the limitations of MBR, which is four primary partitions.
So what does it means?
It means that OSX + EFI + Recovery HD + Boot Camp partition = 4 primary partitions and thus any attempt to modify the disk will render booting issues of either system.
For more info on GPT (GUID Partition Table disks VS Master Boot Record or MBR in short, you may visit: http://msdn.microsoft.com/en-us/library/windows/hardware/dn640535%28v=vs.85%29.a spx)
So, how to overcome it?
The general guideline is to install ALL GPT ready OS first then create a Data partition, before installing Windows (Which is again, NOT supported GPT due to EFI configuration by Apple where end-users are not able to modify it).
Interestingly, since Mac Pro 2013 Late supports only Windows 8 and above, thus it is not known if this CSM-BIOS applies to it or not.
Do take note that GPT disks in Windows can only be booted when the system meets the 2 requirements:
http://msdn.microsoft.com/en-us/library/windows/hardware/dn640535%28v=vs.85%29.a spx#gpt_faq_win7_boot
1) Windows x64 version (Which is a must for newer Macs. If you cannot go to Boot Camp 5, then you need Windows 7 x86 or 32bit version)
2) UEFI system. However, Windows sees all Macs (With the possibility of Mac Pro 2013 Late is an exception. To be determined) as BIOS, or rather NON-UEFI system.
In short, booting on GPT disks is not possible for Mac in Windows.
Summary,
It is tested that a combination of the following will not work:
- OSX + Windows + Linux
- Windows + OSX + Linux
- Windows + Linux + OSX
Usually it can create the system un-bootable or OSX refused to install due to the system does not recognize such partitions and / or Disk Utility refused to format a free space. An example screen-shot is provided below:
The error message is shown as
Title: "Failed to erase volume" Message: "Failed to wipe volume, as an error occurred: MediaKit has reported that the device does not have enough free space to execute the requested operations."
The second thing is about the preparations we need.
1) 1X Windows 7 or 8 DVD or USB thumbdrive
1A) If you uses a DVD to install, you will need another thumbdrive to load the BootCamp drivers for Windows as well as may requires an external DVD drive for newer Macs
2) 1X Linux DVD of your choice. Personally I choose Fedora 20.
So ready? Let's go.
1. Using Disk Utility, shrink the OSX's partition size to what is needed. For me, I give OSX 150GB. Do NOT create any new partition.
Disk Utility should see something like below whereby only OSX partition is left with desired disk space. The remaining space are to be unused disk space for the moment.
Note: Click on the top most item that should start with the size of your HDD / SSD. Then clicked on "Partition" and specify the desired OSX size. Hit "Apply" after that.
2: Download Boot Camp drivers only via Boot Camp Assistant. The USB thumbdrive shall be used later after Linux's installation.
Boot Camp Assistant should see this:
I have only selected "Download latest Windows Support Files from Apple"
3. Insert Linux DVD, reboot Mac into EFI mode (The left most first "EFI mode").
Note 1: Before rebooting, please plugged in an Ethernet adapter because Wi-Fi drivers is not installed.
Note 2: For Thunderbolt adapters, it must be plugged in before reboot as hot-swapping is not supported under Linux. More on the tips at the end of this article.
Note 3: Press and hold "Option" after the screen turns black. Release Option key after you see the image as below:

For the unfortunate part that did not make it on time to edit the images:
9. Install the Windows Support software from your CD/USB drive to gain full functionality of your computer. Reboot and go to Windows again.
Note 1: You may choose to eject disc at this point of time. For Apple SuperDrive users, you will need to wait until the drivers (i.e. Boot Camp support files) is installed and rebooted before ejecting is reasonably possible (As I failed to figured out how to right click without the drivers)
Note 2: Unlike Windows 7 on KBase article TS4599 Keyboard/trackpad inoperative, black screen, or alert messages when installing Windows 7, USB stick can be plugged in after the Windows installation is done. This is because Windows 7 (And probably Windows 7 with SP1 DVD) does not have a built in USB 3 drivers when it was released back in 2009 where USB3 has not arrived then.
Note 3: Due to TPM, Bitlocker is not supported without the use of thumbdrives.
10. Using Disk Management to determine the given drive letter for the DATA partition (DO NOT DELETE and RECREATE partition or else you can goodbye to booting Linux and OSX). Disk Management will not allow you to format it as exFAT / FAT32 in graphical way.
Note: You may remove or modify some of the disk letters in Disk Management. However, do NOT remove / modfify the drive letter for the partition with 200MB size in HFS. This is because it will disallow booting of Linux and neither could Windows nor OSX can do anything EXCEPT to reinstall Linux only.
11. Open Command Prompt in Administrator Mode (Important!!), and key in the following command:
format F: /FS:exFAT
Give this volume a label after it has successfully formatted before hitting "Enter" again.
Note: Mine Data partition was assigned as F drive. Please make necessary adjustment to "F:" should your Data partition is assigned to other letters.
12. After that, Setup your Data partition structure as you like.
Tip: Minimally create the important folders such as:
- Music
- Documents
- Movie (Videos)
- Downloads
- Pictures
All these folders are commonly used by the 3 OSes. I do NOT recommend changing of /home (OSX and / or Linux) and / or user home directory (Windows) either partially or as a whole.
This is because of compatibility issue.
On a side note, iTunes Media Library used in OSX and Windows are NOT able to be use interchangably due to hard-coded path used.
13. Useful troubleshooting in Fedora / Linux:
With references to these:
http://chaidarun.com/fedora-mbp
http://anderson.the-silvas.com/2014/02/14/fedora-20-on-a-macbook-pro-13-late-201 3-retina-display/
http://unencumberedbyfacts.com/2013/08/16/linux-on-a-macbook-pro-101/
I would like to highlight a few important points:
1) Wi-Fi driver:
http://rpmfusion.org/Configuration
Note 1: The sound driver should be installed at Out of Box Experience. However, the Wi-Fi is not.
Note 2: Install both free and non-free repository. By the way, some other software like VLC can only be found after the Free Repository is installed.
Search for "akmod-wl" in Gnome-Package-Installer in order to install Wi-Fi drivers
Note 3: For those who do not have Ethernet adapters and their Mac does NOT have a built-in Ethernet port, it is recommended to get one. This is because Fedora 20 does not have a good support for iPhone USB tethering. Unsure for Andriod / Blackberry / Windows Phone users.
2) Grub Menu:
It will show several options to boot into OSX, even of the capability to boot into x86 or x64 mode. However, neither of them is bootable except Linux and the rescue.
Hence, it is recommended to remove the items by hand in this file:
/boot/efi/EFI/fedora/grub.cfg
Command to be used:
"sudo gedit /boot/efi/EFI/fedora/grub.cfg"
Parts to be removed:
- For any extra kernels, delete the target entry by locating the line "menuentry" under "/etc/grub.d/10_linux" sector to one line above the next "menuentry".
It is recommended to keep one main kernel, and one recovery at the minimal.
- For other OS, delete all the entry (Since neither it can works) under "/etc/grub.d/30_os-prober" sector without removing the lines starts with ###.
Auto Mount exFAT partition:
- After installing extra packages for exFAT support (Since it is not supported by Fedora 20 from a default installation), you may wish to edit "/etc/fstab" in order to mount the exFAT partition during boot time.
Command to be used:
"sudo gedit /etc/fstab"
Add the following line in gedit:
UUID=702D-912D /run/media/Samuel/DATA exfat defaults 1 2
Note 1: For DATA partition, OSX & Boot Camp partition, Fedora defaults mounts under: "/run/medua/<Username with case sensitive>/<Partition Label Name>"
Note 2: UUID is unique ID. You can find out the UUID by:
Step 1: First determine the DATA partition number:
"sudo gdisk /dev/sda"
Step 2: Determine the UUID of this partition number:
"sudo blkid /dev/sda8"
Reference 1: http://manpages.courier-mta.org/htmlman5/fstab.5.html
Reference 2: http://liquidat.wordpress.com/2007/10/15/short-tip-get-uuid-of-hard-disks/
3) Overheating CPU
Solution is to issue the following command in Linux terminal: su -c "echo -n 1 > /sys/devices/system/cpu/intel_pstate/no_turbo"
4) System resumes immediately after suspend
Solution is to issue the following command in Linux terminal: su -c "echo XHC1 > /proc/acpi/wakeup"
5) What does not works well out of box:
- Both GNOME and KDE's fonts are too small to be readable for out of box experience. Additional configuration is a need. (Some of the info can be found on "More Tips" later)
- Thunderbolt hotplugging is NOT supported under Windows and Linux so far. Neither FaceTime HD camera works as well.
- The red light in Headphone jack is always on. I do not have luck in switching off the light without losing the sound.
Note 1: It is determined that the module "snd_hda_intel" is used by both cards (HDMI and normal output)
Note 2: It is also known that blacklisting it can switch off the redlight at the price of muting the system.
Note: Based on this article, http://support.apple.com/kb/TS1574
A Mac (Except Mac Pro) needs servicing when there is a red light while the system fails to detect internal speakers. However, this article does NOT applies to this issue.
5A) More Tips:
Install gnome-tweak-tool for more customization
Search for: "gnome-package" to install:
Install Gnome Package Installer for advanced package repository
Install Gnome Package Updater for advanced updates to be install (Whereby Fedora's App Store alike might not show the relevant updates)
14. Verify if disk is still GPT:
Use Gdisk to determine if the disk is pure GPT:
http://ubuntuforums.org/showthread.php?t=1742682
Command: sudo gdisk -l /dev/sda (The entire hard drive)
You should see the MBR is "Protective" instead of anything else.
15. Congrats, the system is ready for triple boot. (I forgot to eject my Windows DVD when the photo was taken)
Note 1: You cannot set the default startup disk in Linux due to the lack of Boot Camp Control Panel in Linux.
Neither is changing startup disk recommended in Windows due to the inability to display correctly.
For me, I click "Cancel" whenever I am on this tab (Feel free to make other Boot Camp adjustments in other tabs).
Only OSX I know that can show the startup disk options correctly.
Note 2: For some reason, OSX likes to auto mount the EFI partition everytime it boots up. It is not known to have any issue for ejecting other disks or mounting disks via Disk Utility.
Note 3: It is not determined if any Firmware or System upgrades will cause issues. It is only known that all 3 OS's regular updates should not be an issue.
System Updates excludes Mac OSX 10.9.3 updates to OSX 10.9.4 type as I had done it on a OSX 10.9.4 Mac or Windows 8.1 to Windows 8.1 Update 1 since my Windows DVD comes with Update 1.
System Upgrades refers to OSX Mavericks to Yosemite, Fedora 20 to Fedora 21, Windows 8.1 Update 1 to Windows 8.2 / Windows 9 for that matter.
Note 4: Reset SMC and / or PRAM will NOT affect your ability to boot any of the OS (OSX, Recovery HD, Fedora & Windows 8)
Yup, that is it!

Recovery disk Creator & data partition won't work - Satellite L300

My niece asked me to re-install her Toshiba Satellite L300 laptop, because the windows installation is rather buggy. She didn't have a recovery disk. Using Toshiba's Recovery Disk Creator I tried creating a recovery disk.
However, the program wouldn't start. Checking the directory of the program, it would seem that the program simply isn't there. Afterwards, I checked the data partition of the laptop.
There was a map with HDD recovery. However when using Windows' advanced boot (F8 before Windows startup) there was no choice of repairing the notebook. They only choices were the standard windows options (Save mode, normal start, etc.).
In short, it seems impossible to re-install the notebook with the current information at hand.
What would be the next course of action? Is it possible to order a recovery CD from Toshiba?
Another niece has the same notebook, would it be possible to use that notebook to create a recovery disk?
I'll appreciate and look forward to your reactions.

Hi
It looks like something has been changed on the HDD
However, fact is youve no Recovery disk and you cannot use HDD recovery option.
This means you need to order a new Recovery disk from Toshiba.
You can do this here:

PS: one tip if you would use a search option of this forum, you would find the right answer too ;)

Disk Utility - Partition map needs repair because a data partition needs loader space.

I just finished setting up both my OSX and Windows installs from scratch after fitting an SSD, which in-turn was right before my logic board died and Apple replaced it, now it looks like I have some sort of hard drive issue brewing.
This was my plan for the SSD, and how it currently displays in Disk Utility although that wasn't the case earlier:
And in Terminal:
My intention was to have two boot partitions for each OS, 'Macintosh HD' and 'Win 7 Pro' and a third shared data partition 'Projects' on the SSD, which I made in Drive Genius after installing Boot Camp. I don't want Macintosh HD accessible from Windows because I'll be using Paragon HFS+ or MacDrive to give write access and don't want OSs stomping on other OSs turf, hence needing three partitions. Everything looked fine until I just checked Disk Management under windows and realised it couldn't see the Projects volume. Even though it's fine in OS X, it was just marked black/unallocated space.
So I booted back into OSX, all my files look fine so I ran Disk Utility and the Partition tab looked really odd - unfortunately I didn't get a screenshot. All volumes reported their size correctly but visually, Macintosh HD took up most of the drive. I could see 'Windows 7 Pro' under this, but the Partition Layout section had a scrollbar, which if I scrolled down showed 'Projects' squished into a tiny gap at the bottom. I ran a Verify, which reported no problems, and at some time since the Partition Layout has reverted to how it should look (as in the screenshot above), with 'Projects' book-ended by "Macintosh HD' and 'Windows 7 Pro'.
Now when I run a Verify on Macintosh HD or Projects volumes, it says there's no problem, but if I run one on the drive, I get this message:
Volume Macintosh HD on disk0s2 has 0 bytes of trailing loader space and it needs 134217728 bytes
Problems were found with the partition map which might prevent booting
Error: Partition map needs repair because a data partition needs loader space.
I've only managed to find one other mention of this error here, but the fix is not relevant to me because I don't have Sophos installed. I've tried Single User/Safe Mode but it just boots into normal mode, so I can't do a fsck -fy.
** /dev/rdisk0s2 (NO WRITE)
Can't open /dev/rdisk0s2: Permission denied
That value in bytes is exactly 128mb, so I suspect the problem lies with one of the invisible partitions that show up in iPartition and Disk Management under Windows, but not in Disk Utility. I have backups and I suspect the root of the problem is partitioning in iPartition after installing Boot Camp, but I've never had issues with this approach in the past so I'm wary of just giving up and reinstalling Windows again will be massive hassle because I no longer have a SuperDrive and last time it refused to install from USB.
Anyone have any idea what's going on? It seems like the sort of issue Disk Utility should just handle, at least in Recovery mode, but it's not playing ball. It also doesn't seem like a massive problem since my files all look fine and performance is OK, so I'm reluctant to do anything major.
I'll update with a shot of the drive in Disk Management from Windows in a few minutes, in case that sheds light on anything. Thanks!

Similar issue here. I manually partitioned my hard disk for triple boot (using Gparted on Linux), then everything was just fine until I ran bootcamp, to do something as simple as create a boot USB.
I get the same error as a result and have to work my way into booting, by resorting first to a Linux live USB, then restarting from the live USB, to finally reach my rEFInd boot manager, or whichever boot manager should be initialized at startup.
I suppose that the cause in my case is that some operation "scratched" the protective MBR. See this:
http://www.mactech.com/articles/mactech/Vol.23/23.03/APMtoGPT/index.html
I am hoping to fix it using an external Yosemite installation media: see this guide -
http://www.macworld.com/article/2367748/how-to-make-a-bootable-os-x-10-10-yosemi te-install-drive.html
And as a last resort to reinstall.
I'll admit I am negatively surprised. I need this computer for professional reasons, and for the sake of "preserving the integrity of OSX", measures defined by Apple instead tend to make partitions far easier to damage. And this problem seems to affect a number of users.
As for what I have to go through to fix it: a 5GB download, during which I have to register my credit card to the Apple Store. "Pay first, get your free software next."
IF Disk Utility can fix it, from the external media, then fair enough. The hassle is unpleasant but it files as "a choice".
Otherwise you can file it safely under software design calamity.

Lion 10.8.2 + Windows 8 + Shared exFAT data partition

Greetings!
I have a Macbook Pro 13 inch mid-2012 model that I self upgraded to 1TB HDD and 16GB RAM. The system runs flawlessly and VMWare is also fully functional for my basic needs on Windows. However I am at the point that I NEED BOOTCAMP, and VM is not an option for some of my needs.
Here is what I want to achieve, I have read numerous forums but entries either were somewhat dated, or did not have enough details on ALL the 3 aspects I mentioned above in the subject. Here is my plan, I would like to hear suggestions from the experts on this subject matter: I would basically like to have 3 partitions, 1 for OSX (100GB), 1 for Windows 7/8 (bootcamp, 100GB), and 1 for my user folder (remaining space, about 700GB+) which I intend to share between the 2 OS's.
Here is what I already know:
- I have to delete the recovery partition otherwise Windows will complain having more than 4 partitions on the boot drive (EFI, and the 3 others I mentioned). I am fine with loosing the reovery partition
- I know only exFAT is the format supported "natively" for BOTH read's and write's by OSX as well as Windows 7/8.
- I got some tutorials about somewhat convoluted and no so clean instructions on how to actually get the stuff installed, I am ready to take on the challenge and have backups etc so do not mind taking the risks
Here is what I want your advice on:
- Does exFAT perform well enough (as compared to HFS/NTFS on the same physical spinning drive I mean). Has anyone done something like this and if any suggestions
- Is it possible to get files corrupted while sharing the data like this between the 2 OS's
- Is creating the data partition as NTFS and installing some native NTFS I/O handler on OSX a better option if your experience on the above 2 is somewhat negative
- Anything else that I should be aware of?
Many thanks in advance,
Kaushik

Since yours is a newer machine, you have Internet Recovery, command option r held at boot up.
You need a Ethernet connection preferably, use Disk Utility to select the entire drive and erase with the middle selection and wait, it will take some time and map off any potential bad sector it discovers for a more reliable drive.
Next head to Partitions and click the box and set 3, option: GUID, adjust them to size, format the first partition OS X Extended journaled, name Macintosh HD. The second one exFAT and the last one MSDOS, name BOOTCAMP.
Install OS X into Macintosh HD partition, quit and setup. It will likely balk at you and say no Filevault or Recovery HD partition.
Follow the method to install Windows from disk, as you know the BOOTCAMP partition needs to be changed to NTFS by the Windows installer disk before it can install Windows.
Also follow the BootCamp drivers install from Apple.
https://www.apple.com/support/bootcamp/
Use Cabon Copy Cloner to clone the OS X partition to one blank external drive and WinClone to clone the BootCamp partition to another drive.
EFI partition
Macintosh HD partition 100GB
ExFAT partition 700GB
BOOTCAMP 100GB

Repairing Boot Camp after creating new partition

I'm running OS X 10.8 and Windows 7 x64 Pro.
After properly setting up Boot Camp to dual-boot Windows on my Mac mini, I decided to test whether or not it was true that creating another partition (a data partition for OS X) would interfere with Boot Camp. Wikipedia claims it does interfere but without citing a source, whilst the Boot Camp documentation itself only specifies that the disk must be a single partition _prior_ to setup - there's no mention of whether the disk must be _kept_ that way afterwards.
I opened Disk Utility, reduced the size of my OS X parition from 420GB to 80GB, and created a new partition in the unallocated space. Here's how it looks now:
When I attempted to proceed with the process, I did receive a warning that doing this (and I quote), "may" cause problems with Boot Camp. Seeing as it was inconclusive, I thought I'd give it a shot - nothing ventured…
Of course, it borked Boot Camp, otherwise I wouldn't be posting here. Whilst OS X boots just fine, the Boot Camp partition now no longer shows up in the Startup Manager, though it does in the Startup Disk prefPane. If I do attempt to boot into Boot Camp, I receive the following message on a black screen:
No bootable device --- insert boot disk and press any key
The advice given to someone who had this same problem was, "fix your damaged Boot Camp volume." But I'm at a loss as to how to do that.
So, anyone know how to proceed now so that I can keep my partitions as is, whilst fully restoring normal Boot Camp functionality?

How to create another partition on mac and restore from time machine

I want to create another partition on my macbook running on OS X Yosemite. I want to recover a time machine back up on this partition. Basically this is a backup of my other old PC which I saved on a time machine external hard disk and now I want to create it as a new separate partition which I can log into to as opposed to continuous to connected to it via USB.
Any advise on how I can do that?

Hi Patrick,
Thanks for the that great tip.
In that time machine back up I have some applications for e.g. MS office etc and I wanted it to be like a virtual machine as such that I launch when I want to use the applications, see my data etc....I have bought parallels as that allows you to have multiple virtual machines on your laptop whether these are multiple mac images as time machine backups or linux, Microsoft Windows 7, 8 etc....
Thats what I eventually want to do here...
This feature that you provided is also of good reference for me in future.

Partitioning - best way 500gb drive, 3 Linux OS's and a data partition

Hi All
This morning I killed my laptop. No, it wasn't Windows that annoyed me, I was watching the Rugby and wasn't really concentrating. It was 7am kick off though. Anyway, I have decided to completely rebuild the system, and as an interim measure have installed Ubuntu (cos it is simple and quick to install - btw Oneiric is actually not bad at all).
Now, to the question. I have a 500gb hard drive on my laptop. I ideally would like:
1) Essential - data partition of about 80Gb or so. I want this so that I can point Dropbox, Videos, etc. at this.
2) Essential - Arch as the main system.
3) Not really essential - Ubuntu - I do like Ubuntu, and besides i find it convenient to use one Dropbox account on Arch and one on Ubuntu. Ideally I would like to be able to use both on Arch but...
4) Would like - CentOS or Scientific Linux. Essentially a RHEL lookalike. It's not really necessary but it would look better on my cv or whatever. Problem here being that CentOS et al use LVM.
No Windows to complicate things.
What I guess I'm really asking is what order to create the partitions and a suggested layout. I figure on giving a big chunk to the data partition, and then pointing all of the other systems at Documents, Video, Music etc. on the data partition. Whatever OS's I install I just want them to work along with each other, and essentially home (apart from settings) will be on the data partition, i.e. Videos, Music etc.
Any suggestions welcome, particularly in terms of what to install first, second etc. Should the data partition be at the start or end of the drive? One swap partition? By the way my laptop has 3Gb ram.
Thanks
Rich

This way, you could carry your configuration files for apps across distros, if you so choose. Your swap partition would probably only be useful to you if you want to hibernate because you have 3 gigs of ram already. I have 4 gigs on my laptop and I only went above 1 or 2 when I had tons of apps open at the same time. I haven't checked, but I imagine it's less for Arch. If you want to be able to hibernate, it has to at least be the size of your ram. Your root partitions for the distros should be 15-20gb each.
Good point about Swap. I wouldn't mount the data partition as /home because of the possibility of different OS's screwing up the settings. However, I do point the .thunderbird folder at the data partition though because it makes it one heck of a lot easier to keep contacts etc. synchronised across distro's. Not sure this approach would work with everything though. Why on earth haven't Mozilla written a decent method of synching Thunderbird?

As for a layout, here's what I would do:
/dev/sda1 - extended partition to hold everything else
/dev/sda5 - data partition
/dev/sda6 - arch, 15 GB
/dev/sda7 - ubuntu, 15 GB
/dev/sda8 - centOS/scientific/whatever, 15 GB
/dev/sda9 - swap, 4 GB
I had a similar layout in mind to this. Thanks for the suggestions.

How to create new partition on a brand-new Satellite P50T-A0EE?

Hi,
I bought a Toshiba, Satellite P50T-A0EE SLV laptop yesterday with installed Win 8, in Adelaide. First, I realised that only one C:/ partition is available and no additional partition is created for data and for some reason, already 150 GB is used on the C:/ by the factory installed software.
Moreover, checking the disk management, it came up that four primary partitions exist.
One is the C:/, two others are called Healthy (Recovery Partition), and one is the Healthy (EFI System Partition).
As I read up about it, a fifth primary partition is questionable to create, maybe even not supported.
When I just started to launch on C:/ the 'shrink volume' command, much less space was offered to use than it was displayed as free under file manager.
Could someone help, please how to create a separate partition with a reasonable size (600 GB at least from the 1Tb) for data? I would not like to keep my data files on a same partition with windows.
Thanks,
Gerti

Hi dude,
Before you would start to modify the HDD partitions table, I recommend strongly to create an Toshiba Recovery Medium using the preinstall software/tool called Toshiba Recovery Media Creator.
This software creates either the recovery disks (DVDs) or Recovery USB flash memory.
Its very important to create such medium in case you would like to go back to the factory state.
After that you could use an open source software like Gparted tool to create the partitions and to modify the HDD partitions table.

Note: the partitions which are already available on the HDD contain the Toshiba recovery image which allows you to recover the notebook from HDD. But this is possible only in case the HDD partitions table has not been modified in the past.

Problem in Creating New partition in Pavilion dm4 1217TX

I have a hp Pavilion dm4 1217TX model laptop. I want to partition the hard disk (640GB) to separate the OS to the data. I think this is a very basic safety feature that will save my data in case of Windows failure (which is a very common problem). I have already split the C Drive and the new condition of my hard drive is
System           199 MB       Primary
C                        70 GB       Primary
Unallocated   494 GB       Logical
Recovery           32 GB       Primary
HP Tools        103 MB      Primary
Now I can't create partition in the Unallocated space because of 4 Primary Partition it already has. Now what can I do ? I can't understand that why it comes with four Primary Partition and without any Extended partition.

Hi, there, I have the same problem with you, because of the OEM of the laptop, they have partitioned our hard drive in advanced, however this partition is not logical. As we know, when we install Windows7, the system partition and system reserved partition are set as primary partition without doubt, but how could they make the HP tools and other partition as primary partitino too. I'm very unhappy with this. I don't know WHAT are they thinking about. Every one who has a bit comptuer knowloage knows the rules of createing new partitions in Windows. In my situation, I could only copy the data on recovery to C drive, then delete it. and recreate logical partition, then copy it back. Hope this could also help you.

X200 - Windows 7 - Data partition

I hope this message will be helpful. Our X200 we just bought with Windows 7 (32-bit) had only one C partition for the system, the programs and the data. I wanted to create a new D partition for data. Unfortunately, it was impossible to do it with the Windows 7 integrated disk managing tool: I was not able not reduce the C partition under 98 Go, and my D partition was only around 50 Go. The reason invoked was that some files could not be moved (I wonder if those files would not be generated by the Lenovo "Restore and Recovery " program, but I am not certain).
I found the solution with the Easeus tool which worked perfectly. Prior using it, I came back to the initial situation with the only one C partition using Windows 7 tool. Afterwards, I performed a scandisk and a defragmentation just to ensure that the partition was in good shape. Then I created the D partition and adjusted the size of C (around 50 Go) and D (around 100 Go) with the graphical interface. Easeus asked for restarting the computer, and made what it had to make when the computer started again.
I was a bit anxious, but the computer has really been working fine for now more than one week (programs installation, frequent use, etc.).
Like other manufacturers like Fujitsu, Lenovo should provide an option for creating a data partition.
I found this solution on the temporary Windows 7 forum, and promised to myself to give a feedback to the X series community.

Have you been able to solve this?
I'd be curious to hear from other X200 owners running Win 7, do you have any issues with the fan?

Creating a Partition on an new R200?

Hi, I have new portege r200. Came from the factory with XP pro and one partition, taking up the whole of the disk. I'd like to create 2 more partitions on the disk. I don't need to dual boot. Thing is I don't have an external cd writer, though have ext floppy and data key. I've downloaded partition magic 8.0 shareware. Can I create 2 partitions without messing up the OS? If so, how? Is it better to create primary partitions or logical drives?
I did this successfully on my old laptop, which had an internal cd/dvdrom, but used F.Disk. Any advice?

Hi. Thanks for that. I don't think that there is any unpartitioned space on the disk. The primary partion (C: drive) appears to extend over all of it. Though most of the 60 gig is empty of programmes, of course. I'm maybe getting this terribly wrong. It looks like I have to shrink the primary partion, in order to free up some unpartitioned space in the disk, to make room for another partition. Is that correct? If so, can I risk doing that with PMagic without endangering the OS and other programmes in the primary partition? My knoweldge of all this stuff is very rudimentary.
(What I cannot do at the moment is to wipe the disk and start from scratch. I guess I could do that if I purchased and external CD-Rom/RW. The worst that could happen is that I have to buy one and use the rescue disk, I suppose. But i'm hoping to avoid that.)
