Internal HD (aluminium PWB) refuses to be erased.

Erasing the original internal HD on a aluminium PWB does not work.
I friend of mine had a big crash on a aluminium PWB and was no longer able to access the machine. It would get as far as initializing network and than we would get the awful grey restart screen in the many languages.
Thanks to the discipline off backing up no serious data loss occurred and I was also able to access the computer in T mode to safe anything that was not backed up.
I also tried with several tools to get the disk to work again but to no avail.
I decided to erase the disk completely before installing any new software for them (they are pretty illiterate in computer terms). This is where the problem begins. The disk refuses to be erased. Not with Disk Utilities or with TechTool Pro v4. It simply claims to have erased the disk in a few seconds (100 GB).
After several attempts to zero data or erase the HD I gave up and installed the system software from the original CD. This worked but the machine is temperamental and unstable and as I ad more programmes it gets only worse.
Any suggestions? Any ideas?
Thanks

Try this:
1a (If this is the startup drive.) Boot from your OS X Installer Disk. After the installer loads select Disk Utility from the Installer menu (Utilities menu if using Tiger.) Be sure to use the installer disk for the version of OS X you intend to install.
1b (If this is a non-startup volume or external drive.) Open Disk Utility in the Utilities folder of your Applications folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.

My external HD refuses to be erased !!!

My Lacie external hd refuses to be erased.
I have tried ALL of the options in Disk utility - also partitioning,
but all i get is " Unknown error: -20 "
Erasing with the " 8Way random write format" seems to work; but it will LITERALLY take almost a whole week!
Really needs help with this one !
(see also my topic "ERASING REGRET" in this discussion)

I'm relieved to see I'm not the only person having trouble with Lacie's drive. I just bought one, and it is very temperamental. At first, I could not get it recognized at all, so I followed a suggestion on LaCie's website, and disconnected everything, power and all, for 15 minutes. I then partitioned the drive under Tiger. It appears to get temperamental if any other device is connected to Firewire. It would not allow me to write to it or eject it if my iSight were connected, and when I tried daisy chaining my OWC hard drive, it allowed me to copy 3GB of material and then stopped. It now gives an error message saying the file names are too long. When I try to eject it, it says it's in use. The only solution seems to be to turn everything off and restart with only the LaCie drive connected.

Disk Utility: No Mac Drive in Internal HDD. Can't format or erase.

Hey guys, I just got my new mac mini and I installed a Samsung pro 840 SSD. The thing is I messed up. I turned my mac on and everything went fine, Disk Utility showed up telling me that the drive was "unreadable". I decided to turn the thing off and start Recovery so I could install Mountain Lion onto the SSD. When igot to Recovery, disk utility told me there was an error with the drives and it had to erase them, while it was working I got the The Spinning Rainbow Beach Ball of Death so I turned my mac off. Huge mistake it seems. Now when I want to install Mountain Lion there is no available disk to install it. I started Internet Recovery and accessed Disk Utility again and the Internal Drive actually appears but with nothing installed in it. The option to erase or format are not available. I did a disk verification and repair and everything was OK. I'm going crazy over this. Please help me guys!!! I'm leaving a picture so its clearer. THANK YOU!!

Being a new Mac Mini the system is attempting to create a Fusion Drive setup out of your SSD. Do you have dual drives in the system, the built-in one in addition to the new one you installed?
This is an issue with the new Mac Mini and iMac systems (see here: http://reviews.cnet.com/8301-13727_7-57584237-263/disk-utility-may-combine-custo m-drive-setups-on-some-macs/) as these systems ship with Fusion Drive setups and Disk Utility assumes this is the desired setup when you use it to "fix" the drives.
You can see that when you select "Internal Drive" the type is "Logical Volume Group." Since this group is greater than the 840GB, my guess is this is the combined space from your SSD and the built-in one.
To clear this issue, open the Terminal (from the Utilities menu in the OS X installer), and run the following command:
diskutil cs list
You will see a tree of information, with one grouping showing a UUID for the Logical Volume Group (the UUID will be a string of numbers and letters, separated by several dashes).
With this UUID, run the following command to destroy the logical volume group (you can try copying and pasting the UUID, though I"m not sure if the services in the Recovery HD partition support copy and paste--otherwise just type it in manually):
diskutil cs delete UUID
When finished, follow the instructions in the artifcle I linked to above to install OS X to an external drive (if available) and use Disk Utility there to fix and manage the drives, as opposed to the version in the Recovery HD partition.

My ipod won't sync and it keeps coming up with an error message saying "internal error" or it tries to get me to restore from a backup. All of my music and movies have been wiped from my ipod and the apps don't work. The backups don't work either. help.

I plugged my ipod touch into my computer to sync it and it came up with an error message saying that it encoutered an internal error and it refused to sync.
I then unplugged it and plugged it back in and this time it told me that I needed to restore from a backup or set it up as a new ipod. I tried to restore from a backup but it came up with the error message "Backup session failed" every time. I then looked on my ipod and all of my music and movies are gone though it still says that they are on the ipod in itunes. I decided to use the restore function and let that finish. After restoring it still doesn't allow me to sync or back up and The music and movies can still not be seen. I am currently attempting to copy the music and movies to my ipod though this did not work with my apps as they transfered but when I attempted to open them they just crash... If someone could please help me it would be great. It is driving me crazy.

If you get an error that says can't backup, try moving the existing backup file to a safe location and thry again. again. You can find the location of the backup file here:

'erase free space' not secure - it doesn't seem to work?

Just wanted to point out that the erase free space option in Mountain Lion does not seem to work, at all.
A week ago I ran erase free space on my primary data drive then later, out of curiosity, I ran an inexpensive third party recovery program on the disk just to see what happened. Interestingly enough the recovery software was able to find and restore files that I had deleted over a year ago.
This has me thinking, so today I tried it again, only with a 7 pass erase this time. Nope, same thing. After a 7 pass erase (erase free space) this low end, less than $35 recovery software turns up tons of files, everything from stuff I just deleted a few days ago to stuff from over a year ago.
If I'm doing something wrong I would love for someone to point it out to me. Not that I'm toting state secrets or anything on my mac, but still - my privacy is important to me and I assume it is to others.
I'd encourage folks to try this out for themselves.
My set up is a 2011 macbook pro with an SSD as the boot drive, I've got a second harddrive installed in the optical bay and this is where my home folder lives. The secondary drive is the drive where I'm running erase free space.
The only thing that I can think of is that, even though the button is not greyed out, maybe I need to be booted to recovery in order to succesfully run erase free space on system drives?
Any input would be greatly appreciated, otherwise this seems like a pretty ugly security lapse on the part of Apple. Imagine if you're selling your machine and secure erasing before turnign it over to its new owner - and the new owner can run a $35 dollar recovery program and access everything on your machine.
Not good.

Thanks for your response, William.
I think that the issue may have to do with being booted to the system while trying to erase free space. I ran a 7 pass erase free space on a 1TB external Lacie drive this afternoon, the operation took a bit over 6 hours to complete and recovery sofatware is turning up nothing.
This is in contrast to the main drive, which my original post referenced, which is a 500gb 7200 rpm internal drive. A 7 pass secure erase took less than 5 minutes to complete - so, even though the drive is 1/2 the size, there's obviously something not right with the 7 minutes time to complete.
Tomorrow I'm going to try either booting to another account (which doesn't utilize this partcular disk) or booting to recovery and seeing what happens.
I have a feeling that this will solve the problem - I'll post back tomorrow evening.

Installing Boot Camp on a second internal disk

Ok, so I searched the forums for quite some time on this, but couldn't really find the information I was looking for. Really, I just want to share my experience of installing Windows XP 64bit on a second internal disk, operating with leopard 10.5.2 on an dual quad core Intel box:
The directions for boot camp are specific to installing windows on a partition from your OS X drive and can be a bit confusing for people wanting to install on a secondary internal disk. When you first run boot camp, you are presented with 2 options, create or remove a windows partition or start the windows installer. If you have a partition already formatted for windows, use the second option. In my case, I wanted to create an entirely new windows partition.
You are then presented with the option to choose which drive you want to partition. I selected my second internal disk in bay 2, enabling the "erase disk and create a single partition for windows" option. Do not be fooled. This does not format the disk, it only makes a partition on the disk which you will then later format in the windows set-up. Clicked continue with the windows XP disk in the dvd drive, and the system will then make the partition and restart the computer into the ugly windows setup blue dialog screen.
Here's where I was confused. After loading some drivers, you are then presented with the option to format disks... If you were making a second partition on a pre-installed OS X disk, Boot Camp cleverly makes a title on that partition, telling you which is the correct disk to format <BOOTCAMP>. In my case, I was presented with three options. Disk 1 (J:), which had 300 gb, and disk two, which had two partitions in it already, one at 200mb (D:) and one at 280gb (C:).
DO NOT PICK YOUR OS X DRIVE!!! It will erase your entire mac system. The problem is, if your drives are exactly the same size, there is really NO WAY to tell the difference between the two in the windows setup except for some subtle hints. I unfortunately picked the wrong disk, and erased my machine into the ether.
However, after I reinstalled my OS X drive and tried the XP install again, I found there were clues as to which drive to format. Apparently, windows likes to be installed on drive C:. My background is with Mac, so I didn't catch that hint the first time around. Also, if I paid careful attention to the sizes of my drives, instead of guestimating they were both the same (the mac is just a bit larger than the second internal), I could have solved the puzzle long before I began banging my head on the desk.
Formating the drive is straight forward, but takes about 2 hours to do. Windows goes through it's setup, and before you know it, you have a quasi-functioning windows system on your mac. The final step is to reboot, hold down option, click the windows HD, have your OS X install disc 1 in the drive, then install the rest of the mac-windows driver (automatically does this for you).
Boom. You're done.
P.S. I was told by a apple rep that boot camp does not work with a 64 bit install of XP. It worked for me... eventually!
Hope this helped

I understand that you were able to load windows on another internal disk beside the one where OSX resides. In my case I have two drives that are stripped (software raid). Will I be able use bootcamp with windows installed on a third internal disk dedicated to windows?
Thanks...Chris

Miss erased disk? and reinstall MAC OS X problem!

NEEDS HELP...
very new to mac...

"Macintosh HD"
Im completely erased the "macintosh HD' on my macbook using disk utility....
then i try to reinstall MAC OS on it....
but then it couldnt find any disk to locate the installation....
PLEASE HELP ME!!! =(

Does Disk Utility still see the drive? If so, did you format it as Mac OS Extended (Journaled)? (Select the formatted volume, with whatever name you gave it, in Disk Utility and look at the Format info at the bottom of the window.) Also in Disk Utility, select the drive itself, not the volume, and see what the Partition Map Scheme says... should be GUID if you want to install Mac OS X on it.

Problem erasing MacBook drive while booted from external drive

Hello,
I'm booted on a MacBook Pro from an external drive, and I want to erase the drive inside the MacBook using Disk Utility from the external. For some reason or another, it won't let me do this.
When I click on the Erase tab (whether clicked on the disk itself or the volume "Macintosh HD") and try to erase it, it returns with the error:
Disk Erase failed
Disk Erase failed with the error:
Could not unmount disk.
When I try to install an image onto the drive, I get a similar error, except it says "Operation not permitted."
When I tried it while booted with an OS X DVD, it worked fine.
As far as I know, I should be able to do this while booted from the external HD.
Any solutions to this problem?
Thanks,
Jason

Hello Jason and welcome to the discussions. You could try to re-partition the internal drive while booted from the external. Using disk utility from the externals Application/Utilities folder click on the internal drive (the manufacturers #, should be above the internal name) and select the partition tab.
change the partition table and then restore it back to the original. This will wipe out all the partitions and should show the drive as empty. Then I would erase all the free space using the erase tab and selecting your Macintosh HD or whatever you named your new internal startup drive the click on the "erase free space" button. Select "zero out deleted files" then erase. It will warn you that the drive is full when it gets near the end...thats okay just click to ignore or proceed. That should do it.
Cheers,
Glynn

Thanks for the info regarding the latest update. I like some of the new/improved options, however I am highly disappointed that the update discontinued the reminder option. I would think that setting a program reminder is a highly used feature and many will be unhappy now that it is gone. I know I surely am!

Time Machine backup from clean reinstall of mountain lion

I have a few niggles before and after installing mountain lion. Previously using snow leopard.
I want to do a clean reinstall of mountain lion and then use time machine to restore files and folders.
I dont want to do a full restore of time machine as i dont want to restore my niggles.
When I currently go into Time machine the restore button is alwats greyed out.
I am therefore not confident of being able to restore files selectively after clean reinstall.
I must admit I dont fully understand how time machine works after reading various tips and instructions.
Can anyone help or steer me in the right direction please.
Niggles include:-
Cant run Kaspersky or Sophos
Shutdown and restart problems
Small Desktop screen in front of blue screen after leaving idle for a while
Thanks

That button should be enabled once you navigate to a backup and select something.
But it's not going to work that way once you erase the internal HD. That's because the erased drive is treated as being a different one. Since the "old" drive isn't connected, you can't restore things to the place they were saved from, via the Restore button.
But you should be able to select what you want, right-click it, and choose the Restore <item> to ... option, to get a prompt to select the "new" drive.
Also, if you don't use either Setup Assistant or Migration Assistant to put your stuff back, Time Machine will do a full backup of the "new" drive. You may be able to prevent that, by telling it to "associate" the "new" drive with the old backups, per #B6 in Time Machine - Troubleshooting

HT201250 My MacBook is full. I want to 'save' (backup) everything on my Time Capsule and then reset my MacBook to factory settings so it is empty again. Can I access my files on the TC without restoring the whole thing to my MacBook?

I also bought a WD My Book 2T external hard drive, but I think I wasted my money. The thing is not easy to navigate. I bought it because I didn't understand (and still don't really) how the Time Capsule works. I want to be able to basically 'reformat' my MacBook so it is empty, but have all my current stuff accessable so that if I want to find a photo or file, I don't have to restore the entire thing back onto my MacBook.

Then what you want is a Carbon Copy Cloner of your entire OS X boot partition which includes everything (OS X, programs and files) and is hold the option key bootable at boot up (wired or built in keyboard) this way you can boot from it or use Migration or Setup Assistant against it, or access it directly from any computer capable of reading the HFS+ format (Windows PC needs MacDrive installed)
It's like the ultimate backup system, just blows TimeMachine and TimeCapsule away completely in almost every manner.
You need another backup anyway in case TC wasn't doing it's job. With the clone you can check it out completely before erasing the original drive too.
Most commonly used backup methods
So you need a blank powered external drive formatted Partition: 1 option: GUID and format OS X extended journaled in Disk Utility, use the Erase > Secure >Zero (or middle selection in 10.7+) and allow that work, may take a few hours but it's good for all new drives to be done once.
Next download CCC and select your boot drive and clone it to the external drive, then when it's finished you hold the option key down (wired or built in keyboard) and while booting up (Startup manager) to select the clone to boot from and check it out.
Next you need to use Disk Utility (on the clone) and select the Macintosh HD partition of the internal drive and use the Secure Zero Erase (or middle selection) and allow that to work, it will scrub your drive of everything.
Next you install OS X again.
How to erase and install Snow Leopard 10.6
How to reinstall just OS X or erase/install OS X
Next you install your free iLife and third party programs from original sources

Then you can cherry pick just want you want off the clone drive.

Upgrading from Snow Leopard to Yosemite

Hello,
Long-time user of the forums, first-time poster (such a fantastic wealth of knowledge here!).
One question prior to installing Yosemite:
Does anyone have any experience installing from Snow Leopard to Yosemite - ideally with a Macbook Pro 15-inch mid 2009?
The second question is more closely related to what I do after I make the install, which I plan to do to a test partition first:
If I install to a partioned drive, will I still have the option to install onto my original drive (and then I would delete the test partion - I presume this is the best way to do it) if I like Yosemite and wish to go ahead with it? Will I just be able to use my Mac log in again?
If I don't like Yosemite, or it is incompatible with my mac, will I be able to easily remove the newly partioned test-drive, with Yosemite on it?
Lastly, Will I need to reinstall Microsoft Word for Mac 2011? As I don't have the boot disks I just wanted to check this.
I plan to run the usual diagnostic precautions (Time Machine Back-up, Verify/repair Disc permissions,make sure all software up to date) Many thanks all,
Much appreciated.
Below are my specs:
Macbook Pro 15-inch mid 2009
HDD: 250 GB
Model Name: MacBook Pro
Model Identifier: MacBookPro5,4
Processor Name: Intel Core 2 Duo
Processor Speed: 2.53 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 3 MB
Memory: 8 GB (I upgraded to this about 18 months ago)
Bus Speed: 1.07 GHz

Hi Kahjot,
Wow - fantastic this is so useful! So I would partition the external HDD first? And then clone my current OS to both of those partitions? And I would need to run the whole of the OS off my external drive - I would need to keep it in at all times...?
If possible can you please describe the process of cloning it back on to my internal drive - will this remove all my existing apps etc that I have modified over the course of the month?
Many thanks again,

You would really only have to keep the external attached when you want to fool around with the clone that you updated to Yosemite. You could either run off the external for Snow Leopard, or from your internal drive. I'd pick one and stick with it. Let's say it's the Snow Leopard internal drive. You would clone it to your external Snow Leopard partition from time to time to keep that clone up to date. If you decide that you really want Yosemite on your internal drive (you may not!), you could make a final clone of your internal drive to the Snow Leopard partition, to make sure that you still have it and can go back to it when you need to, and then you would clone the Yosemite drive onto your internal. That would, of course, completely erase what is on your internal drive and replace it with the Yosemite system. Or you could just run the Yosemite installer (that you wisely saved) to update your internal drive that way.
I am thinking in terms of cloning with software such as SuperDuper or Carbon Copy Cloner: I've never used Time machine. I can't advise you on how reliable Time Machine is, or how easy it is to restore a system with it. You might do some research here on that. SOme users have reported missing files in their Time Machine backups: http://www.macintouch.com/
One "gotcha" with Carbon Copy Cloner, which I prefer because it clones the recovery partition, is that you will need version 4 to clone Yosemite onto anything, and an earlier version (3.5.7) to use within Snow Leopard.
When you download the Yosemite Install app, it will launch itself. Don't run it immediately. Quit the Install app, and option-drag a copy of the installer to a safe location (not in your Applications Folder!). The Apple OS installers starting with Lion have the annoying habit of deleting themselves from the Applications folder after the installation is finished, so if you allow that to happen and need to install it again, you have to download it from the App Store again.
One snag is that Yosemite volumes are not seen by Snow Leopard's Startup Disk pref, so you will have to switch from Snow Leopard to Yosemite by rebooting with the option key held down.

Possible solution for those suffering from poor battery life - data dropouts etc...

I was having the same bizarre data dropouts - an FDR and cache wipe with no app/data/settings restore fixed it for me, yes it IS a pain in the rear - YES it will take a couple hours if you have a ton of apps and accounts - YES it IS worth it, phone is working as it should now!
Cache Wipe:
Press and hold the Power button and turn the phone off.
When the screen turns off, press and hold Volume Down and Power.
When the white HBOOT screen appears, use the volume button to move down to “RECOVERY.”
Press the Power button to select “RECOVERY.”
When the triangle and exclamation appears, hold the Volume Up and Power button at the same time.
Using the volume button, scroll down to “Wipe cache partition” and select it.
Select “Reboot system now.”
Before doing the FDR do this:
Menu-->System Settings-->Privacy-->under the Backup & Restore items clear the Automatic Restore checkbox.
***NOTE*** By doing this you will lose everything on the phone and internal storage(NOT on the microSD) - you will have to manually reinstall all apps, setup all accounts etc...it take awhile to do but it has solved 99% of the issues I was having: dragginess, dropped 4G, poor battery life etc...
Factory Data Reset
From the screen of your phone, press the Menu button
Tap System Settings.
Scroll down and tap Privacy
Tap Factory Data Reset
Check Erase internal storage if you would like to erase all the data on the phone internal storage such as applications, music, movies or photos.

Reconnect to TM backup after HDD replacement?

I have just got my iMac back after a warranty repair that included a replacement of the HDD. They migrated all of my applications and data from the old HDD to the new one and everything seems to be fine. However, TM wants to doesn't recognise the existing backup file and wants to do a full "first time" backup (which is a problem anyway as there isn't sufficient space on my Time Capsule).
Does anyone know whether it is possible / how to get TM to recognise the existing backup as relating to this machine?
I just worried about deleting the existing backup only to discover there is a file missing that I might have been able to restore from the "old" TM backup.
Thanks, Brian

TM knows it's the same Mac; the problem is, it isn't the same internal HD. And no, there's no practical way to fool it into thinking it is.
If your TC isn't well over twice the size of the data on your internal HD, your only choices are to erase the TC's internal HD, or get another external HD.
You can connect a USB drive to your Time Capsule and back up to it (it will be a new backup; the old one can't be "continued" onto a different drive); or you can "archive" the TC's current contents to it, then erase the TC's internal HD and let Time Machine start over.
See the green box in #Q3 of the Using TIME MACHINE with a TIME CAPSULE *User Tip,* also at the top of the +Time Capsule+ forum, for instructions on doing the "archive".
