Securely erasing HD and ejecting disk

I just got a 24" Intel iMac to replace my old flat panel mac (yay!).
I want to sell or donate my old iMac, so after transferring all the data, I reinstalled the system software on the old iMac, choosing to erase the HD. So far so good, but now when I start it up, I get the welcome screen which i can't get past without registering my name, address, etc. I can just shut it down, but how do I get the disc out? I'm planning to include the install disk anyway so I suppose it doesn't matter, but still it seems there must be a way. Also does reinstalling the system software with "erase" option checked SECURELY erease the data?
Thanks for replies!

"Also does reinstalling the system software with "erase" option checked SECURELY erase the data?"
Depends upon your definition of SECURELY.
1. For the truly paranoid, the only secure method is physical destruction of the drive.
2. Mac OS X has an option to do a fairly decent job of erasing data. See Disk Utility/Erase/Security Options. It takes a long time (many hours) to run, but will stop most everyone except the NSA.
3. Reinstalling the software with the erase option will prevent most people from seeing your data.

I start my macbook air up and a file comes up with a question mark. When I go to Disk Utility I go to update things or erase everything and my disks don't show up or anything. Anyone know what to do?

These are related but not identical issues. Their causes are outlined in Intel-based Mac- Startup sequence and error codes, symbols. Solutions may be found in:
A flashing question mark appears when you start your Mac
Mac OS X- Gray screen appears during startup
In most cases the problems may be caused by:

Repair the Hard Drive and Permissions
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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
The main difference if you are using Lion or Mountain Lion is that you must first boot from the Recovery HD:
Boot From The Recovery HD:

DVD studio pro won't finish and eject disk

I have been having a problen with dvdsp. it will write the disk and then it hangs up on writing lead out. I actually have to re start the computer to get the disk out. The disk plays but why will it not finish?

Last night I tried to just burn the video_ts file with toast and it did the same thing. I actually had to shut down the computer and restart to get the disk to stop and eject. Today I tried toast again but this time I slowed the burn speed to 8x (was at 16x, using mamorex 16x disks) and it worked. I don't know if the disks are crap or not. I have had good luck with them but I have only burned 160 of them and had probally 5 coasters which is good right? Is there a way to slow the speed down in dvdsp?

HD secure erase, reformat, and clean install.

BRIEF HISTORY:
i selected the manufacturers (fujitsu ...) HD from the list in disk utility booted from the mac os dvd. i first erased free space then selected it again and erased the entire disc securely w/ the 1x zero out method. then formatted it and chose one partition guid type, sized at 111.83 GB. the size of the fujitsu drive. clicked ok and the newly formatted drive size listed as only 111.47 GB with a dialogue box saying "this volume will not be erased".
MY QUESTION:
according to apple phone support (2 diff techs) i should be able to create the partition the same exact size as the manufacturers size. they sent me to genius bar who said its normal due to ds.store but the difference/mb should be only 10-15 max. which one is right? is there a different operation to completely start fresh? without replacing the drive physically.
advance thanx for the time/effort to help

Hi notfunny;
No. It is the directories and other system area so that system is able to find everything that is stored on the disk. If you want you can think of it as system overhead.

Bootcamp Not Install Xp. Restarts and Ejects disk???

Hi,
I have an Alu 24" imac running Snow Leopard and using Bootcamp 3.x
I had a previous Windows Xp bootcamp partition but it was getting a bit small and i felt a nice clean install would do it some good as well.
So i opened Bootcamp Assistant, deleted the old partition and ran a disk permission on my mac drive just to get the yin and yang all back together.
I created a new Bootcamp partition (Bootcamp icon appears on desktop, etc) made it 105gb and popped in my WinXp sp2 disk. I then hit Start Installation. My mac restarts, takes a while on the white screen ejects my disk and then loads my log in to mac os x. I tried again. Bootcamp, start install, it restarts, takes a while then ejects and takes me to the mac log in. So i restarted again and held down alt. Only the mac drive pops up, no other option to boot into even with the cd popped in.
Any ideas? It's the same cd i used for the first bootcamp partition i had, i've also tried my win7 cd that i used in parallels file and the same thing happens?
Thanks in advance,
Tara

I got mine to work
I'll tell you what i did in case it helps fix yours as well but i don't know if this is an actual solution or just worked for me but here goes.
I finally decided to create another version of the dvd i had which was an orginal win7 downloaded from my school's MSDN account.
I popped in the dvd which mac os x mounted fine and opened it up - bunch of files and folders as it's supposed to have.
I opened Disk Utilities, highlighted the dvd in the left side and hit create new image. When that was done my new image file name appeared on the left also, I clicked it then hit burn, put in a new blank cd and let it go. When that was done i ran the Bootcamp Assistant an hit start installation. It restarted and loaded up the WIN7 boot cd.
So i reckon i just needed to stroke my mac's ego a little. Yes, mac you did all the work, you even created the cd, good boy, now load it, yes well done
I hope that helps someone else, if not good luck on finding a solution that works for you to

Time for Secure Empty Trash and Free Disk Space

Hi Forum,
Can anyone give me a guesstimate of how long secure empty trash would take or can take? I have 290 items and its been there for about an hour.
Also, if I choose to free disk space, how long approximately would this take? Is it worth doing this? I have 40gb "free" now.
Thanks.
S

it's not necessarily the number of files, but more the total size of all the files combined. But lets just say it dose take a while to do. you really only need to use secure empty trash on files of a sensitive nature. Such as financial information (credit card numbers, back information, social security numbers)
Also by spending all that time writing to the hard drive, over and over. Witch is what secure empty trash dose. your reducing the life span of your hard drive. Like car tires your hard drive is only good for so many miles.
I ones secure emptied trash on a GB worth of data. I remember it takings hours. I ones tried scrubbing a whole hard drive, after two days I stopped it because I didn't realize it was going to take so long. That being said it doesn't take too long to scrub a few files that are a few MB in size.

Kernal panic and ejecting disk

i was trying to load a new os on my g5 , (by the way, real upset that i can not buy leopard anymore) everything was going well until i got a kernal screen, now i can not eject that disk or figure out what the prob is, is there a way to start in safe mode
?

A PRAM/NVRAM zap should clear the default boot path from what it is set to.
You may have either left out or not used the Option (Alt) key as part of 4-key boot into Open Firmware.
Holding Option (Alt) on startup at least stops it at the boot manager and yes, lets you eject CD/DVDs.
And all because the physical 'eject' key is not accessible on Mac

After secure erase of disk ready for sale of MBP I needed to input my AppleID and password in order to install operating system. is this a problem for the buyer?

I ran a secure erase of the hard disk ready for sale of my MBP 2007 (Snow Leopard). But then I needed to input my AppleID and password in order to download and install an operating system (Yosemite). The screen the showed the Welcome opening as it does for a completely new machine. It is ready for a new owner to register and use his or her own AppleID. Will the fact that the OS was downloaded under my AppleID mean that the new owner will still be able to update it as necessary when the time comes?

You can't sell that computer with an OS newer than 10.6.8 on it(or 10.7.5 if you originally got Lion from a thumbdrive and not the Mac App Store.) Any higher version will be tied to your Apple ID.

Consistent OS bug when ejecting disks (Mac OS 7.5.5 to 10.4.9)

I have a problem and a complaint about a bug in every Mac OS since 7.5.5, up to and including 10.4.9, and it is about disk images and ejecting disks. It has already happened to me twice tonight, and I hate rebooting my macintosh so frequently.
The problem has been both highly repeatable and extremely annoying because I have to reboot the computer every time it happens.
Its simple to repeat, just put a cdrom in the drive--I'm using an imac G4 USB with OS 10.4.9 at the moment but I've verified a similar problem occurs with floppy disks in various OS versions back to 7.5.5 on a Mac SE 30.
Next use Disk Utility to make a copy of the disk. I make a copy on the desktop and keep the same name as the original disk because I want to use them for archives. Now open the disk image to inspect its contents and make sure it looks right. Once the disk image opens on the Desktop it becomes impossible to eject the cdrom.
I've tried:
- the media eject key--graphic flashes but nothing happens
- dragging the icon to the trash can--icon disappears but the disk doesn't eject
- remounting the disk in Disk Utility and then using 1) the eject command, 2) the media eject key, 3) dragging the disk icon to the trash can.
Since I have an iMac G4 USB (the flat panel) the computer doesn't have a manual cdrom eject. The only way I've found to change cds is to reboot the computer and hold down the mouse button. Every single time I copy a disk I have to reboot--I hate that.
This bug is really overdue to be squashed. Until then, is there a way to force the cdrom to eject without either 1) damaging the drive or 2) rebooting the computer?
I don't want to damage the computer by forcing the cdrom drive open. Nor do I want to keep rebooting every time I make a disk image.
Thanks,
- Mike

Can you eject the disk after unmounting the .dmg file? Can you eject the disk if you change the .dmg's name slightly? BTW, my mate has a 17" 1GHz G4 iMac and her keyboard has an eject button.
If none of those work, the file a bug with Apple through their BugReporter system. Go to https://connect.apple.com/MemberSite and join the Apple Developer Connection (ADC)—it's free and available for all Mac users and gets you a look at some development software. Then, go to https://bugreport.apple.com/, click on the Login to the Apple BugReporter link (using your Apple ID username and password), and file your bug report/enhancement request. The nice thing with this procedure is that you get a response and a follow-up number; thus, starting a dialog with engineering.
Posting here won't get you any action from Apple engineering.

Can't do factory restore & only disks that keep ejecting are the osx install and apps disks

First of all let me say, this is my first Apple computer and I'm not experienced in forums. Please do not read rudeness into what is actually frustration at searching forever for a solution and trying not to wish I had been talked into an Apple. With that said....
I've had my iMac for about a year and a half. We had lost our internet and were using a hotspot for awhile so we could look for another provider and get online if we needed to. One day I signed on and, we didn't have an isp mind you, but the browser opened up to the dominant isp in this area saying a virus was detected coming from this iMac address? I thought that was strange and panicked so decided to do what I would on a pc, just restore the whole thing to factory settings. Everything was going smooth, (my updates were at 10.6.8 at the time)... when I restored I was back at 10.6.2. (osx disk) I was doing systems updates and one apparently hung.... when told to restart, I did... but the computer would never boot back up. It would turn on.... go to gray screen... then blue screen... then shut off. I couldn't boot in safe mode, pram reset did nothing, smc reset did nothing, couldn't hold 'd' to get to diagnostics, couldn't boot to recovery... it kept spitting out disks after trying to read them... with all those solutions I found online and nothing helping I had to call Apple... they couldn't help over the phone because Apple Care expired, unless I purchased help... this frustrated me because every where I found my problem and a different solution their Apple Care had expired too.... so had to set an appt at an Apple store.
So took it in to Apple, just got it back yesterday. I let them know I was restoring to factory settings so wasn't worried about losing anything. When I picked it up, I was told no charge... it was a software issue they saw where it hung and fixed it. I tried to ask questions about the 'software repair' but they didn't seem to want to answer my questions. It just says 'software repair' on my order. So I asked 'okay, so it's back to factory settings like when I bought it?' I was told yes and I said great that was my goal anyway. I get home and it's NOT like when I first purchased it or like a factory restore. Everything I was doing before it crashed is on there. So I'm back to trying to do a factory restore. But for some reason now, it seems the only disks that keep self ejecting are the osx install and application disks. I still can't do a boot recovery, AHT, or 'c' boot... since the apple disks eject I can't use start up to get to them.
I find it odd that both the oxc install disk and applications disk would be damaged at the same time when they both previously worked. I called the Apple Store where I took it to talk to the geniuses that worked on it because I had a question about the repair they did....
Apple: I'm sorry we don't offer tech support
Me: I understand but I had a question about the repair done from there the other day
Apple: We are just a store and can't answer tech questions
Me: I understand and get that but since I took my mac to your store to be worked on I thought I could ask the person that worked on it a question about the 'software repair' and meaning and what software was repaired
Apple: No you will have to set another apt to bring your computer in if you are still having problems
Me: UGHHHHHH (pulling hair out)
So (a little late huh?) to make a long story short giving what I stated above:
Why is it, only the osx install and application disks not working now? They worked before taking it to Apple
What can I do at this point?
Can you do a factory restore without disks on a Mac?
If by chance both disk did for some reason go out, how do I get them replaced?
If I gave TMI without enough important info let me know.
My OS X install disk says version 10.6.2 on it
About this Mac currently says Mac OS X version 10.6.8
Batteries died on keyboard and mouse so am using usb wired keyboard and mouse
At some point I had used bootcamp and then later found parallels so I could install a Corel product and keep using... could some windows files be messing something up in there somewhere?
It used to say Mac OS X Version 10.6.8 and I could have sworn I saw it said 'snow leopard' in there somewhere, now I can't even find that word in search on the computer. Long post I know but trying to set what was going on at the time I took it in.
I'm not sure what else needs to be added to get this to the correct thread or help. As I stated my goal is to have it like I just pulled it out of the box for the first time so no solution will scare me off about loss of data.
Thanks for any help.

Wow, sorry to hear of your experience. Seems strange that your disk would just eject like they did. It could be a lot of things but more than likely you just kind of have to start all over.
What I would do is insert your system disk and instead of going immediately to an install I would go to disk utility and erase the drive. That will erase everything on the disk and give you a new blank disk to start with. After that I would try to reinstall the system. Assuming that goes well then you should be restored to where it was when you purchased it. After that you can reinstall all your applications or personal files. I hope you have good backups.
I remember one time I was having a similar problem and don't ask my why I did it but I actually could not get it to install a system. I removed both of my ram sticks, shut the computer down for about 10 minutes including unplugging it from the wall plug, then reinstalled the ram, plugged it back in and started up from the system disk and all worked just fine. To this day I have no idea if pulling the ram helped but I have never had to do it since and for some dumb reason that solved the problem I was having, which is the same problem you are having now. Call it voodoo but it worked.
Good Luck!!

How can I securely erase my Apple TV's Hard Disk?

The 40 GB drive is too small as everyone is experiencing and I need to upgrade my Apple TV’s hard disk to a 250 GB drive that are now available. I thought of doing it myself but it is not quick and I do not have the time people are reporting. Therefore, I decided to send it to a company to do the upgrade. I would like to securely erase the hard disk before I sent it out, because the company told me that they do not return my old hard disk. However, I do not know how to erase my hard disk, especially how to make a secure erase. Will Apple’s Disk Utility see the Apple TV’s hard disk to make a secure erase? I tried but it is not coming up in its pane. I would appreciate your help, please. Thank you, Tumay

There is no way to securely erase the drive without removing it from AppleTV and using a utility.
Best thing you could do would be to do a system restore which should erase the files, and then sync with a load of rubbish a couple of times (make some dummy video/music files) if you want to overwrite stuff on the drive. Seems unlikely that the company in question would be interested enough in your files to use professional data recovery to try and recover what you had on there.

Disk Utility - secure erase process does not complete

Help, please!
It is taking "for ever" for Disk Utility* to securely** erase (a) the 37.25 GB hard drive in my G4 Powerbook (while booted from a startup disk), and (b) an external 55.9 GB firewire hard drive (connected to a 17" G4 iMac).
After more than a day, the progress bar for the Powerbook is only about half way over, and the progress bar for the external hard drive is only about 1/7 of the way over. (See the notes marked * and ** below.)
Additionally, the note next to the progress bar for the Powerbook has changed from "Writing random data to disk" to "Creating partition map".
Yesterday when I tried this process previously, after a very similar situation developed I quit Disk Utility on both machines and started the process again - so now the situation is about the same as before I quit Disk Utility yesterday.
* I am using Disk Utility v10.4.4 to erase the external drive. I am using Disk Utility off the boot disk for OS X v 10.3.3 for an iBook to erase the Powerbook - but I can't see what version at the moment because the pointer is currently a spinning "beach ball".
**By "securely erase", I mean I selected the option to write random data eight times to each location.
(Prior to starting the secure erasure process, I had Disk Utility write zeroes at all locations - and that process did completed within a few minutes for each hard drives.)

How can I securely erase my hard drive and reinstall OS X Mountain Lion?

Hi, I am selling my MacBook and I was wondering if there's a way I can securely erase my hard drive, (... 7 pass, 35 pass) using these steps: http://www.mactip.net/how-to-securely-wipe-your-mac-hard-drive-before-selling-it /
and also reinstall OS X Mountain Lion afterwards.
Thanks in advance. 

Boot into recovery mode by holding the command and r keys down during boot. Bring up Disk Utility and do the security erase you want to do. When done, choose to download Mountain Lion.

Erased free space in Disk Utility, and after it finished it kept a DMG there.

I erased free space in Disk Utility, and after it finished it kept a DMG there called "DeveloperDiskImage.dmg", why is it left behind? can it be deleted? how? if erasing free space is supposed to help get memory and remove all the files truly, it shouldnt be creating anything, it created a DMG at the start, but it went away, after a hour and a half it made the DeveloperDiskImage, i went to eat dinner and when i came back it was done but that was left.

Delete it. Erasing the free space isn't supposed to free up any space; it's there in case someone deleted a file insecurely when they meant to securely delete it.

Using Disk Utility Secure Erase Makes it hang?

Hi, I wanted to erase part of my drive (I was doing a generalized clean-up). I tried using the Disk Utility Secure Erase option. Even going with the single pass -- I'm just cleaning off free space, you know? ANyhow, it seems to hang a lot. The other functions on it seem to work ok. I looked at the force quit option and it says it isn't responding.
I did try just leaving it alone for a really long time, but unless I am doing the 35-pass erase it shouldn't take all night (which it did at one point and it still wasn't done).
(Computer is a MacBook late 2008 13" aluminum)
I had it do a repair and after I forced it to quit it said it did find bad areas of the disk and repaired them, or so it said.
But then I tried a verify and it seemed to crash again. So I get the sense there is something weird or fishy with Disk Util for 10.5.8. Any thoughts? My copy of TechTool works fine, it seems. Disk Util seems a bit unreliable right now, and I don't want to damage anything. But I also want an option to clean off the disk if I ever sell the computer or something like that. (I've been ID theft-ed once already, I'd rather not go through that again).
