How to completely erase ( no recovery partition remaining) a lion partition with disk utilities on lion install disk?

Where in a lion install disc made from the installer can I find a bootable file with disk utilities?
I downloaded lion a few hours ago and installed.
I have 4 large hardrives (1.5TB) arranged in 8 partitions to allow me to work on a varied group of projects. I have some projects that need to be worked on with software running under Tiger, some with software that runs under leopard, some with snow leopard, and now Lion. I own multiple copies of software and multiple user pack system install discs.
On a regular basis, I back up chunks of work on projects to external discs, and special backup areas on one of my drives. I don't like using time machine because I am running many operating environments on my mac pro and I don't ever want to be tied to one operating environment for important functionality, and I want to maximize the open space on my hard drives.
Several partitions involve large video files. I am working on them in various versions of final cut, premiere and imovie. Because I have to use the same software versions my different clients are running, I don't want to move all the files " up" to a modern version. It would be professional suicide to stop accommodating my various clients. I say this to try to head off being told to make my clients upgrade. There are too many different clients and they are not going to replace all their equipment.
On these volumes with video files, I often fill them up and copy off what I need to backup before I erase and do a clean install. I also run VM Fusion and windows XP. I absolutely do not want to have a Recovery HD partition left on the drive when I erase or influencing the other partions using different OS versions on that same drive.
Is there a bootable disc on the installer disk I just made? Can I use the disk utilities to do a low level erase on the lion volume that will remove the recovery partition?
Can I go back to booting from Snow Leopard and erasing the Recovery partition with the drive partition that way? Will the Snow Leopard utility take out the Lion HD recovery partition?
I am used to erasing my drives and rebuilding my machine and I believe it is the right way to use my multiple drives in my workflow. Now that I've got this invisible recovery partition, can you help me remove it and create a bootable disc that includes disk utilities?

I assume the unix pdisk command will show you want is going on.
You may not have a big worry. There have always been a lot of hidden partitions. Disk Utility under 10.4.11 reports this drive has three (my now report four ) partitions, when pdisk reports that there are 15.
Macintosh-HD -> Applications -> Utilities -> Terminal
Press return when done typing sudo pdisk -l
-l include a lower case L
The sudo command will ask for your administration password. No characters will appear when typing your password. Press return when done typing. sudo stands for super user do. It's just like root. Be careful.
mac $ sudo pdisk -l

How do you make a bootable install partition from a disk image of an install disk.

I have an iMac g4 running Leopard and would like to install OS X 10.3 on a different partition Leopard is on. However the super drive in the iMac will not read the disk I have, so I used my MacBook Pro to make a disk image of the install disk to use to install on the iMac. I do not know how to make the disk image into a bootable partition so I can install 10.3. The person I bought it from has already created a partition of the Leopard install disk and it is bootable but I do not know how he did this. Please help me. Thanks!

Could be the cd is bad. Could be a bad cd reader.
I' not sure what you are trying to do.
To install,
-- you need to boot from a cd.
-- copy a working installation from another partition. try carbon-copy-cloner
-- could try target disk mode. There is a cd sharing mode.

How to completely erase Lion and Reinstall SL

Also how many times can you erase your HD and not damage the Drive? This will be the 3rd time i have erased and started over.

Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.

This might depend on how you made your installer. If it is a flash pen installer that you made yourself, depending on how you made it, it has consequences on what is installed.
I am assuming that you have made an installer?
If you have and you did it manually, without using the Terminal command then it is a know caveat that a recovery partition is not installed as part of that procedure. The second method to create a bootable installer, using Terminal, will allow and install a recovery partition.
See here (without Terminal): http://www.macworld.com/article/2151706/create-a-bootable-mavericks-install-driv e-for-newer-macs.html
& here (with Terminal): http://www.macworld.com/article/2056561/how-to-make-a-bootable-mavericks-install -drive.html
Alternatively, have you zapped the PRAM and SMC, prior to trying to install?
See here: About NVRAM and PRAM
Some of these might help or even answer your query...
Good luck.

How do I erase the hard drive on my 2007 Macbook with operating system 10.4.11 ?

I am going to recycle my old Macbook and want to erase the hard drive. When I go into utilities-disk utility-click on Macintosh HD-and the Erase tab, the only active button is Erase Free Space. The Security Options and Erase button are not active. How can I erase the entire hard drive? The operating system is 10.4.11.

You have to boot to another drive. You cannot erase the drive to which you are booted. Typically you would use the system installer discs that were provided with the computer originally.
Alternatively you can use another computer which is running OSX and put the old one in Target Disk Mode. The old one will simply be seen as a normal hard drive which you can erase.
How to use FireWire target disk mode - http://support.apple.com/kb/HT1661 - includes description of hardware and software requirements. [What to do if your Mac doesn't enter FireWire Target Disk Mode|http://docs.info.apple.com/article.html?artnum=75414], also read about [Open Firmware Password Protection|http://www.apple.com/support/downloads/openfirmwarepassword.html] which can disable Target Disk Mode.

Trying to erase hard drive on MacBook before resale, but dvd player not working for install disk. Is there a work-around?

I have a new iMac running 10.6 if that helps.

If your MacBook and your iMac have firewire ports you can install by Target Disk Mode. You'll need a retail version of a Mac OS to do this if you don't have your MacBook's gray install disks.
Start up your iMac with your install disk. After you get to the install screen on your iMac connect your MacBook to your iMac in "Target Mode" with a firewire cable http://support.apple.com/kb/HT1661
Then open "Disk Utility" from the "Utilities Menu" on the Menu Bar from the install disk on your iMac. You should see both your MacBook and your iMac hard drives in there. Erase and partition your MacBook drive and then choose that drive when you go back to the install screen.

2011 macbook pro with Mavericks - do I need install disks to erase hd?

So I inherited my dad's 2011 macbook pro and updated to Mavericks, and added myself as a user on the computer. I want to erase the HD so that I can start over, be the only user, 'own' the computer, etc., but when I open disk utility the erase buttons are grey. I also don't want to erase the HD and find out that I need to order 2011 era OSX install disks. What's the deal? Thanks!

You can't use Disk Utility from the drive that you want to erase. Depending on whether you have an early or late 2011 machine, it may have shipped with Snow Leopard, and with discs, or with Lion, and no discs.
Go under the Apple menu and select "About This Mac", "More Information," and see if it's an early or late model. If it's a late model you can do what you wish with no discs, using only Internet Recovery.
Call back,

Physical partitioning have anything to do with where data is on the disk?

Hi All,
I've read through numberous threads here and understand the difference between physical and logical, but no discussion (that I've seen) has asked if there is any relation of physical partitioning to how the data is organized on the disk. For example in SAP the options for physical partitioning are 0CALMONTH or 0FISCPER, so when you select, lets say 0CALMONTH, does that also mean that all your cube's data for March 2010 is physically read and written near all other March 2010 data on the disk?
Conceptually this makes sense to me as part of the reason for improved performance because the disk won't have to move very far to retrieve all related (in this case March 2010) data.
Is this true? or am I extrapolating too far?
Thanks.

I read that thread and in the SAP library which is quoted, it says, "you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units."
So what is meant by physically independent in this definition? The way I've described it seems compatible, since data of similar partitions are physically seperate on the disk, though again I'm not sure if its true.
More inputs would be appreciated... points have and will continue to be awarded.

I want to install hybrid drive in Macbook pro. I bought my Mac book with lion and am now running mountain lion. I was told I needed install disk to set up new drive before restoring from my time capsule.Is this correct and if so how do I get disk osx10?

I purchased a Mac book Pro in Aug 2012 with lion and have upgraded to mountain lion. I currently am looking to install the segate 750 gig hybrid drive. I watching video I shows me needing a OSX 10 disk to boot off of when the new disk is in and the use time capsule to restore system from back up drive to new hybrid. Hope I got this correct so far. that being said my Mac Book did not come with a disk therefore is one available, when I get to point of restoring from back up with it be the same mountain lion system I had. Sorr if this sounds redudant.. Thank you in advance

Connect the new hybrid drive to your MBP. Start up your MBP holding the OPTION key, the two HDD icons will appear. Select the 'restore' icon on the right. When you get to the menu where you have 4 options, select Disk Utility. Format the drive and then you can use the option of restoring it from Time Machine.
Ciao.

How can I use an external USB drive on my Macmini with Boot Camp and Lion/Windows 7?

I have a MacMini (Last model with a disk drive). The Mini has Lion and Windows 7 installed using Boot Camp. I want to attach a 350GB, USB, HP Personal Storage Device (Hard Drive) to the computer and be able to use it in both Lion and Windows 7 mode. The USB drive is formatted for Windows 7. I only want to use it for storage and back-up purposes for both operating systems. It would be nice if I could access the total disk from either system without having to reboot to change operating systems to view Windows 7 files and reboot again to view Lion files. Can anyone offer any guidance or any informational websites to help me? Thank you for any help!!

Yes, you’ll be able to do that.

I want to completely erase and rebote my computer

Someone just told me how to do this but they were talking about disk utilities and I can't figure out what that is. I looked on my installation disc one and it talks about selecting a destination but I don't know where that is located either. Can anyone explain either of these or give me more specific instructions of how to completely erase my laptop (to get it back to the factory settings) and re-install everything.

Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo appears.
5. Wait for installer to finish loading.
Use the Tiger installer disc that came with the computer (gray label.)
Drive Preparation
1. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. DO NOT click on the Install button.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. After formatting has completed quit DU and return to the installer. Complete the OS X installation.
Alternatively, from the installation options select Erase and Install which does the same thing.

Windows based WD external hard drive not showing up in Disk Utility to reformat to Mac... how can I erase the drive

We have a WD external harddrive previously used with a PC that we want to completely erase and reformat for use with our iMac desktop for use with Time Machine. The drive shows up on the desktop of the Mac, but it does not show up in Disk Utlity, assuming because it's Windows format. Outside of the standard "erase" feature in Disk Utility, is there any way to reformat this drive for Mac OS X? Or how can I get this drive to show up in Disk Utility? Note: The drive functions properly, has power, and we are able to view its current contents through the desktop icon, so it is a working drive. And we are ok with losing all the current data on the drive.

Hmm strange, I had just moved my external Lacie drive from my windows machine to my iMac and it was showing up in disk utility still formatted fat32 or whatever. I would disconnect the drive and restart the machine then replug the drive and try again.
Also not that it will make a difference ( I dont think it will but hey why not ) try accessing disk utility from the install disk?

How can I restore the recovery partition of Lion without erasing drive?

Hello there,
I have a mid-2011 MBP equipped with Snow Leopard, but at one point I needed to access the AHT, which doesn't boot from the second DVD, released months before. It turns out this Mac requires AHT to run from Lion's Recovery HD partition. Since this Mac doesn't contain any Lion software, is there a way I could install the content of Recovery HD without reinstalling Lion itself so I can have the AHT ready if I need to? Of course I don't want to erase nor get rid of Snow Leopard. Drive is not original.

Apple Hardware test is only available two methods on Intel Macs
Pre-July 20, 2011 Macs through the prebundled installer discs you can order for around $20 from AppleCare if you lost the disc. The 'D' key boot then boots off the disc that contains the hardware test
Post-July 19, 2011 Macs through the 'D' key boot (no CD/DVD necessary, and no installed software necessary)
Both methods are described here: http://support.apple.com/kb/ht1509
Dates given are based when the vintage of the Mac was sold through Apple authorized retail stores, and not when you bought an operating system or purchased used or refurbished.
