How to erase a Partition?

I want to erase the secon partition of 32gb that is been used for windows, I changed to VMware Fusion so I dont need to have a second partition.(I think)
So I want to have in just one.
But How to erase that 32gb Partition? on Disk utilities doesn't let me click in any of the options to erase.
If I have to have to be an administrator account, there it is I am the only one that uses the computer, and in only one account.
So please If anybody can help me.
(ps.: Bootcamp assistant has expired)

How to erase Windows partition with Boot Camp

I used Boot camp to create windowsXP partition, but windows got corrupted and I want to go back to zero by having boot camp erase the windows partition. The boot camp instruction setup guide says to open boot camp assistant, Introduction window and click on the third category " Restore the startup disk to a single volume". However, when I open Boot Camp Assistant there is no Introduction window as shown in the printed guide. Where do I find this so I can restore to a single volume again?
iMac Intel Mac OS X (10.4.8)

Try downloading the brand new Boot Camp version that Apple just posted within the past week (1.1.2 IIRC). Install the new version and it should give you the introduction screen again where you can remove the Windows partition.

How can I reformat my hard drive if erase and partition don't work in disk utility and I get an error when I try to erase and install from the Leopard install disk? I have had several kernel panics, but the volume shows up in startup disk.

I have had several kernel panics on my iBook G4; the panic message shows up just after the desktop appears. Although the startup volume shows up in Startup Disk, the installation disk reports an error when I attempt an erase and install. Disk utility is unable either to erase or partition the hard drive. The hard drive shows up in disk utility, but the startup volume doesn’t HELP!!!

Do you have the original system discs that came with the iBook when it was new?
Which exact iBook model is it?
You can choose from this list:
http://www.everymac.com/systems/apple/ibook/index-ibook.html
Erasing the disc and installing Mac OS X 10.5 will result in loss of the other applications (such as the iLife applications) which came pre-installed on the iBook.

How can I erase NTFS partition on my Mac

Hi Warder, Welcome to Apple Discussions.
Disk Utility cannot unpartition a drive without erasing the entire drive. There are some utilities that can unpartition on the fly DriveGenius is one. (I'm not sure if it is Universal yet) Prosoft is a trusted software vendor but I would still do this "at your own risk".

Any need to defrag (by (reverse-)cloning) after erasing Windows partition?

I did this before creating the partition because I didn't have enough contiguous space to create it, then started doing it again after erasing the partition thinking it might be safest to assume the space might not get used as efficiently as the space that had been reserved for OS X.
Based on some very quick research, it seems like this was a silly assumption. But I haven't seen any article explicitly addressing whether any kind of hard drive maintenance/optimization might be useful after erasing a partition. Can anyone confirm that this is because it's just not something to be concerned about?
I've already nearly finished by clone/reverse-clone process, but I was thinking about doing it for my girlfriend's computer, too, since it's in the same situation. Looking to save some time.
Thanks in advance.

Here is a link to an excellent user tip by ds store that will likely answer any question.

How to erase and install new version os Mac Os X?

Can someone tell me how to erase and install new copy of Mac OS X 10.5.8 ?? IS there a way to do this without CD?? I no longer have the disks and I cant find a way to get this done.. The reason I want to do this is because a 12 year old was using this computer for a long time and there is a lot of junk stuff on the disk, so I want to start from fresh.
Thank you in advance.
Yani.

Hi Yani,
Your out of luck without an Install Disc, & on dangerous ground also.
2 ways to go...
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
   3. Click the Erase tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion do a new install.
Or...
Open System Preferences>Accounts, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.
In the same pref pane highlight your old account, click the little minus icon, then use Disk Utility to Secure Erase Free Space.

How to delete a partition entirely?

I had a bootcamp partition, and I can't figure out how to completely get rid of it. I've erased everything ON the partition but I can't seem to figure out how to restore the partition's memory back to the original Macintosh HD partition.
Since I used disk utility to erase it, bootcamp assistant won't give me any options as to how to delete the partition. It's using up 50gb of my harddrive and I need the space for my original partition.
Any help would be greatly, greatly appreciated.
Thanks so much

Select the drive in the sidebar, click on the Partition tab, delete that partition, and drag the slider at the bottom of the Mac OS X partition as far down as it will go.

How to erase a MacBook from a pawn shop ?

Here's a synopsis of what I'm dealing with. Ive never owned a MAC before so I thought instead of spending a grand for a new one I would see if i could find one locally. so I purchased an early 2008 Black MacBook with OS X 10.7.4 Lion from a local pawnshop. The person who had it before me was still logged on and it had all kinds of accounts set up and such. So I went online and researched how to erase all of that. I did the restart holding the option key which brought me to the MAC OS X Utilities. I selected Disk Utility then selected Macintosh HD and then the Erase Tab. After that I clicked security options and then selected single pass of Zeros. Clicked ok and the clicked erase. It took about an hour and then I selected to erase the free space. After that I went to to the MAC OS X utilities options box and selected Reinstall MAC OS X. All said and done its now asking me to input my Apple ID and then it says my ID has not purchased the operating system.
Now what do I do ?
Do I really have to go to the iTunes Store and buy lion ?
If that's the case Mountain lion is only $20 will that work as well?
Once I purchase the software, do I go through the motions again to have it installed like before ?
Should I just buy a hard copy rather than doing it over the Internet ?
Much needed help would be appreciated. I've spent days working in this and now my GF wants to kill me. I need this fixed soon.

Buying a used Mac from any source is best left for experienced Mac users, for the very reasons you described.
At best you purchased an expensive education, at worst, stolen goods.
All said and done its now asking me to input my Apple ID and then it says my ID has not purchased the operating system.
A 2008 Mac would not have had OS X 10.7.4 "Lion" already installed, and it is impossible for you to install it from the Recovery partition since the license to use Lion is not transferable by any means. The seller (more than likely, the thief who stole it) erred in not restoring the Mac to its original condition before selling it to the pawn shop. Without that MacBook's original System Install DVD - which the pawn shop didn't supply, right? - it will not be useful to you.
There are no "hard copies" of Lion available. Lion exists only as a download from Apple, whose servers check your MacBook for a legitimate purchase of it.
Your best alternative is to phone Apple at the number shown on the Apple Online Store website. Explain that you purchased a used Mac and require a replacement System Install DVD. Use those exact words. Have the MacBook's serial number ready for them - it will be required.
Determine the Mac's serial number using the following: http://support.apple.com/kb/HT1366
Apple will collect a nominal fee, $25 or so. Once you get the disc, boot from it by starting the Mac by holding the c key with the disc inserted, and pray the original owner did not configure a Firmware Password.
Reinstall its original operating system from that disc, after which you will have reached Step 1 toward using your Mac.
After installing it, you will need to purchase Snow Leopard from the Apple Online Store, unless its original OS was already Snow Leopard (yours was probably OS X 10.5.2 "Leopard"). Snow Leopard costs $20.
Only after installing Snow Leopard can you purchase Lion from the App Store. You will need to call the Apple Online Store again and purchase a download code since Lion no longer appears in the App Store. That will be another $20. You will "redeem" this code in the App Store.
Your MacBook is too old for Mountain Lion.
Total cost: $65 + tax + whatever you already spent.
Tell your GF she was right. Do that now, to prevent further compounding your misery

I cannot erase or partition new MB Air SSD drive

I have a two month old MB Air which was delievered with Snow Leopard and since upgraded to Lion at the AppStore.
Five days ago it turned itself off because of low battery power and it would not start up again even after 1 hour of charging the battery. I heard the system open but the screen was black. Finally, on the fourth restart, I just typed in my password into a black screen and it started and came back to life, but everything is completely messed up. No permissions repair because of an SUID error. No ability to erase the disk and reinstall the software (all grayed out). No ability to partition the solid state drive (all grayed out). Reinstalling LION on top of existing system does zero to improve the situation.
Does anyone know how I can get the SSD to erase or partition and do a clean install from the LION dmg I have (or go back online to download it again?)
To make things worse, I just opened the thumbnail drive with the system recovery software that came with the NEW MB Air and it isn't even recognized as a drive on this computer, or on a 3-day-old MB Pro I had to buy out of desperation while the MB Air is out of order, or on my 2-year-old MINI. Now when your new computer dies, that's bad enough, but when the unwrapped and untouched Recovery thumbnail drive won't mount on ANY computer, that is insult to injury.
So far from Apple, bring it in for service. But I am in France for a month and I cannot deal with the French Apple store people in Paris because of language problems and this is "vacation time" in France which means come back in September.
Does anybody know how to FORCE this thing to erase or partition so I can try to correct the problems? I am at a loss here.
Thank you.
Mike

Hello Leigh
Thank you for the information. I was hoping to avoid installing Snow Leopard 10.5 which would then have to be updated with a 1gb update to 10.6 BEFORE it could be upgraded to LION. I am in France in the country on holiday and using a low bandwith and high cost internet connection. C'est la vie. There was no way to get the Lion dmg file to give me any options whatsoever to use Utilities to access the Disk Utilities and erase the disk. Just never appeared. The full dmg in fact reverted to the internet to download files and the estimated time was four hours. Perhaps after that four hours I would have been given an option to erase and install "clean" but I didn't get that far.
The thumb drive with OS 10.5 never showed up in the finder or in Disk Utilities.
I am working through it now and I hope to be finished in two hours.
Moral of the Story: Never let your computer shut down automatically because it is out of battery power. Disaster.
Thank you.
Mike

How to use Oracle partitioning with JPA @OneToOne reference?

Hi!
A little bit late in the project we have realized that we need to use Oracle partitioning both for performance and admin of the data. (Partitioning by range (month) and after a year we will move the oldest month of data to an archive db)
We have an object model with an main/root entity "Trans" with @OneToMany and @OneToOne relationships.
How do we use Oracle partitioning on the @OneToOne relationships?
(We'd rather not change the model as we already have millions of rows in the db.)
On the main entity "Trans" we use: partition by range (month) on a date column.
And on all @OneToMany we use: partition by reference (as they have a primary-foreign key relationship).
But for the @OneToOne key for the referenced object, the key is placed in the main/source object as the example below:
@Entity
public class Employee {
@Id
@Column(name="EMP_ID")
private long id;
@OneToOne(fetch=FetchType.LAZY)
@JoinColumn(name="ADDRESS_ID")
private Address address;
EMPLOYEE (table)
EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID
1 Bob Way 50000 6
2 Sarah Smith 60000 7
ADDRESS (table)
ADDRESS_ID STREET CITY PROVINCE COUNTRY P_CODE
6 17 Bank St Ottawa ON Canada K2H7Z5
7 22 Main St Toronto ON Canada L5H2D5
From the Oracle documentation: "Reference partitioning allows the partitioning of two tables related to one another by referential constraints. The partitioning key is resolved through an existing parent-child relationship, enforced by enabled and active primary key and foreign key constraints."
How can we use "partition by reference" on @OneToOne relationsships or are there other solutions?
Thanks for any advice.

How to accelerate by partitioning drives & how to distribute data among 'em

Dear forum,
I have read guide to storage acceleration and guides to phototoshop acceleration, but they always warn that the best solution depends on the work i do, the hardware i have, and the hardware i think i can afford to buy. I'm hoping that if i tell you what photoshop work i do, what hardware i have, and what hardware i'm intending to buy, you can tell me how to accelerate by partitioning my drives and how to distribute data among them. My biggest questions are about how big the volumes should be, and what should go on each volume. It sounds vague here, but I get more specific below:
THE PHOTOSHOP WORK I DO:
*wet-mount raw scans of 6x7 cm film using silverfast software on microtek artixscan 120tf 4000dpi scanner: resulting 16-bit TIFF file is typically 550 MB in size.
*working in Photoshop CS2 on same file, adding multiple layers makes file 1 GB to 1.4 GB in size
*my system's limitations show up most painfully when I OPEN a file (this can take five minutes) SAVE a file (this can take more than ten minutes!), when i FLATTEN the image's layers for printing (this can take 5 minutes), and when i CONVERT the file from 16-bit to 8-bit (this can take 5 minutes). most other operations in Ps CS2 are fast enough (not snappy, but fast enough) for me to stay with my current processor for the time being.
THE HARDWARE I HAVE:
*Power Mac G5 dual 1.8GHz, made in 2004, with only 4 slots for RAM (not 8 slots).
(I'm told this has quite limited bus speed, as compared with other dual-processor G5s, and that this hardware will not benefit much at all from adding a RAID array.)
*one internal seagate 80GB 7200rpm SATA drive. this is half-full (it has 39 GB on it): it holds my OS and my Users folder, but NOT my photoshop image files.
*one internal Western DIgital 400 GB 7200rpm SATA drive. this holds my photoshop image files, but not my user folder.(This WD drive turns out to cause the G5 to hang up occasionally, requiring a re-boot; to avoid this, i recently learned, i can connect it with a host card adapter [see below].)
*two 500 GB external firewire drives
*two 300GB external USB drives
*I have 2.25 GB of RAM, but I'm about to buy 2 more GB to max out at 4GB.
THE HARDWARE I'M INTENDING TO BUY:
*2GB of RAM, of course.
*two Hitachi T7K500 500 GB SATAII HD 16MB Cache 7200rpm drives to occupy both internal drive slots in the G5
*a 2-drive external enclosure to hold my old seagate 80GB drive and my old WD400GB drive.
*a seritek host card adaptor for connecting the external enclosure to the G5.
THE PLAN:
What follows is a combination of suggestions I have received about what I could do and my speculation about how I could do it. Please see my Questions, embedded in the lines below: I'd be very grateful for any amendments or directions you can offer on this topic.
Drive A: first newly internal Hitachi 500GB drive:
partition into 2 volumes:
first (faster) volume, "volume A1," of 100GB to hold OS and Users folder but NOT photoshop image files.
(Question: how much space should I leave free on volume A1 for optimum performance? is 50% free of 100GB optimal? is 60% free of 100GB better? Is 50% free of 150GB better still? or does that cut into the other volume's space too much (indirectly cutting into the space of "volume B1" on Drive B, which is to be the WorkDisk/ScratchDisk)?
second (slower) volume, "volume A2" of remainder GB (almost 400GB) as backup for 400GB "volume B1" of the OTHER internal Hitachi Drive, a.k.a. Drive B.
Drive B: second newly internal Hitachi 500GB drive:
partition into 2 volumes:
first (faster) volume, "volume B1" of almost 400GB as designated WorkDisk/ScratchDisk for large photoshop image files;
second (slower) partition "volume B2" (exactly 100GB) as backup for 100GB volume 1 (OS volume) of the OTHER internal Hitachi Drive, a.k.a. Drive A.
(Question: how much space should I leave free on this WorkDisk/ScratchDisk for optimum performance? is 50% free of almost 400GB optimal? is 60% free of almost 400GB better? Is 50% free of 300GB just as good, with the additional advantage of indirectly allowing "volume A1" on Drive A to be 150+GB?
Drive C: old Seagate 80GB drive, in external enclosure: disk designated for running the Photoshop Application? How would I set this up? any pitfalls to watch out for? should i partition this drive, or leave the whole thing for Photoshop? or is it better to run photoshop off Drive D?
Drive D: old WD 400 GB Drive: second scratch disk? Storage disk? Both storage and scratch disk? how large should an empty volume on this disk be in order to be useful as a scratch disk? volume 1 or volume 2? if i run the Photoshop Application off of this drive, how large should the volume for that be? should it be volume 1, the faster, outside volume, leaving volume 2 for scratch disk space? or vice versa?
External Firewire and USB drives: i guess i'll just use them for storage/archiving and extra backup? or am i much safer buying more SATAs and Enclosures? or are the external firewire and USB drives plenty safe (so long as i double-back up), since i'll only power them up for the data transfer, and then power them back down?
Given that the large Photoshop files are not in my User folder, does it matter whether i keep the User folder (with its MS Word docs and a bunch of PDFs and so on) on my OS volume, "volume A1"? would it speed things up when I'm using photoshop if i moved the Users folder to another drive? what if i'd like to play iTunes while also working on photoshop? my iTunes music folder (with all the song data) is already on an external firewire drive. but the iTunes Library and iTunes application are, of course, in my User folder, which is on the OS drive. would moving the Users folder to another drive make much difference when i use photoshop and iTunes simultaneously?
But I wonder whether it makes sense to be using volume A2 on Drive A as a backup drive: wouldn't it make more sense to back up my working files to two external drives that can be traded out, one on-site and one off-site, back and forth (not so convenient when one of the backup drives is internal!)? and after all, why would i devote a 400GB volume to the task of backing up another 400GB volume that will never be more than half full? I need to leave a WorkDisk/ScratchDisk half empty for efficient use, but i can back up that 200GB of working files on a 200GB volume, right? so for a backup drive, I might as well use a slow, inexpensive external USB drive that will only be tuned on for backup and will then stay powered off, a drive that's easily transportable on and off site, right? or am i misunderstanding something?
by the way, what backup software do you recommend for backing up back and forth between Drive A and Drive B? I've been using Carbon Cpy Cloner. do you recommend that? or something that does more archiving of progressive states of data?
Thank you for any help you can offer!
Sincerely,
