Partitioning - does it erase data?

I have MacFuse, which is meant to enable my Macbook to write to a NTFS formatted external hard drive, a Maxtor Basics 500gb.
I need to partition the hard drive, so it has a Mac part and a Windows part. Can someone advise whether partitioning is safe, ie will it erase the existing data? How can I partition without erasing existing data?

Thanks for prompt response. Is there an easy and cheap way to back up the contents of the external hard drive, given that my Macbook (120gb) is full, and I am wanting to shift files from the MacBook to the external hard drive ... I assume I need to back up the external hard drive to another device ... can I copy its contents to my time capsule before I partition? then I would have the external hard drive's data somewhere else ... Will MacFuse enable me to do this, as previously I couldn't write from the external hard drive to Time Capsule.

Partitioning External Drive w/o Erasing Data

I have one 500GB external drive (USB) that I want to partition. I have 85GB on data on it now and really don't want to copy it back to the Mac HD (if at all possible).
When I run Disk Utility/Partition and select 2 partitions, it allows me to shrink either partition to ~52GB - smaller than my current data size. So I'm not confident what I am doing will partition w/o erasing data.
The drive is formatted as Mac OS Extended (Journaled).
My eventual goal is to use SuperDuper for a clone backup. I'm using the free version that only allows erase & copy. If I purchase SD, could I add a clone to the external w/o erasing existing data?
Any other suggestions?

yes you can.
quote from disk utility help:
Creating new volumes on a disk
You may be able to create multiple volumes on your disk without losing any data. Each volume works like a separate disk. You may need to create a new volume if you want to install multiple operating systems on your computer. Volumes can also help you organize your files.
NOTICE: Back up your data before creating new volumes on your disk as a precaution.
To create new volumes on a disk:
Select the disk from the list at the left, and click Partition.
Select an existing volume in the Volume Scheme list, and click Add .
Disk Utility splits the volume into two, leaving the data in one of the new volumes. If the volume is less than half-full, Disk Utility creates two volumes of equal size. Otherwise. it creates one volume large enough for the data, and another volume with the remaining space.
Resize the volumes as needed.
You can drag the dividers between the volumes in the Volume Scheme list, or you can select a volume in the Volume Scheme list, and then enter a value in the Size field.
Choose how to format the volumes that will be erased or created.
For each new volume, select it, enter a name, and then choose a format.
Click Apply.

Just an update... A rep contacted me and we did a screen share. They were convinced that I wasn't full of <insert proper word here>. They promised to get back to me in a few days, and now? A few months later? Nothing.
Still no files. Still no correction... Still no nothing from Adobe.
The person I spoke to was kind, saying he'd make sure I got CC for free for a while...
Still though, no follow up.
Adobe, are you going to correct this or just let your customer suffer at your mistakes?

I used a partitioned HDD for time machine, using a partition already containing other data files. I am now no longer able to view that partition in Finder. Disk Utility shows it in grey and "not mounted". Any suggestions of how to access the files?

Yes, sharing a TM disk is a bad idea, and disks are cheap enough so that you don't need to.

"Erase data" vs "Reset all settings"... do both erase Restrictions?

I would like to prevent my son from resetting his iPhone, thus erasing the Restrictions (General>Restrictions) I have set.
I think that he can't use the Reset function (Settings>General>Reset) without knowing his iCloud password (which he does not know).
But what about the "Erase all data" function (Settings>General>Passcode Lock>Erase Data) when one enters a Passcode wrong 10 times? Would that also erase the Restrictions? And if so, is there anything to prevent that from being done?
It looks as if that feature can be turned off, so that 10 Passcode attempts does not erase the data, but there is nothing to prevent a person from going in and turning that feature back on.
Thanks!

Note: If you lose or forget a restriction passcode, you will need to perform a factory restore to remove it.
The above comes from here:
http://support.apple.com/kb/HT4213
However, performing a factory restore would turning off Find My iPhone on the device, which disables Activation Lock. This is described here:
http://support.apple.com/kb/HT1414
But ... turning off Find My iPhone requires the Apple ID and password, which you say is not available!
So, you're safe!!

How do I turn off the new "Erase Data" feature

With 2.1, in Settings>General>Passcode Clock, there is the option to "Erase Data" which will "Erase all data on this iphone after 10 failed passcode attempts". Mine is set to "Yes", but is grayed out so I cannot turn it off.
How do I turn it off?
It is a cool feature, but my kids pick up my phone and try to use it all the time - it is only a matter of time before they try ten times and I'll be screwed.

Mine is set to on as well and greyed out.. Here is the catch. Im syncing to my companies exchange as well. For all our smart phones they request a mandatory pin and require a remote wipe after 10 failed attempts. Now if you think back to when you setup your exchange.. did it require you to put in a pin, and can your disable that pin if you wanted? if the answers are yes and no respectively then chances are your company does the same thing mine does and you would not be able to disable the erase data option unless you stop syncing to echange. Hope this was helpful..

Hello, I am trying to upgrade to yosemite, but I get the "disk cannot be used to startup your computer" error. Resizing the partition does not work, I get the error "MediaKit reports no such partition" probably because I installed linux in dual boot

Hello, I am trying to upgrade my macbook pro to yosemite, but I get the "disk cannot be used to startup your computer" error.
Resizing the partition does not work for me and I get the error "MediaKit reports no such partition" probably because I installed linux in dual boot and the disk manager is lost.
Anyway to tell the yosemite installer that it should not pay attention whether the disk is bootable or not ?
If I am doomed, any way to delete the installer and downloaded OS from my hard drive ?
Thanks for your help

As usual, the Linux installer wrecked the partition table. You would have to boot from your OS X installation disc and repartition. Doing so will of course remove all data from the drive, so you must back up first if you haven't already done so.

Partition w/o erase?

Just got my iBook repaired by AppleCare. I want to repartition the hard drive, and I was wondering if there is any way to add a partition with out erasing everything already on it. (It would be a pain for me to use the Tiger disk to install, and then to have to do a software update on everything) I guess I could carbon copy clone my the iBook and then partition it and carbon copy clone back the old OS? Does this work? Any other ideas? Thanks.

Thank you. So I guess I ought to use Carbon Copy Cloner. Do I have to use the root folder of the target external drive, or is there a way I can create a folder on the external and carbon copy clone my laptop to that folder? Thanks.

‘iPad is disabled’ fix without resetting using iTunes
Today I met my match with an iPad that had a passcode entered too many times, resulting in it displaying the message ‘iPad is disabled – Connect to iTunes’. This was a student iPad and since they use Notability for most of their work there was a chance that her files were not all backed up to the cloud. I really wanted to just re-activate the iPad instead of totally resetting it back to our default image.
I reached out to my PLN on Twitter and had some help from a few people through retweets and a couple of clarification tweets. I love that so many are willing to help out so quickly. Through this I also learned that I look like Lt. Riker from Star Trek (thanks @FillineMachine).
Through some trial and error (and a little sheer luck), I was able to reactivate the iPad without loosing any data. Note, this will only work on the computer it last synced with. Here’s how:
1. Configurator is useless in reactivating a locked iPad. You will only be able to completely reformat the iPad using Configurator. If that’s ok with you, go for it – otherwise don’t waste your time trying to figure it out.
2. Open iTunes with the iPad disconnected.
3. Connect the iPad to the computer and wait for it to show up in the devices section in iTunes.
4. Click on the iPad name when it appears and you will be given the option to restore a backup or setup as a new iPad (since it is locked).
5. Click ‘Setup as new iPad’ and then click restore.
6. The iPad will start backing up before it does the full restore and sync. CANCEL THE BACKUP IMMEDIATELY. You do this by clicking the small x in the status window in iTunes.
7. When the backup cancels, it immediately starts syncing – cancel this as well using the same small x in the iTunes status window.
8. The first stage in the restore process unlocks the iPad, you are basically just canceling out the restore process as soon as it reactivates the iPad.
If done correctly, you will experience no data loss and the result will be a reactivated iPad. I have now tried this with about 5 iPads that were locked identically by students and each time it worked like a charm.
~~~~~~~~~~~~~
Try it and good luck. You have nothing more to lose if it doesn't work for you.

Main partition does not work

Hello,
I have an iMac with a 2TB Hard Disk. It is partitioned to have a nearly 1,99 TB "Main Partition" with the System and everything on it. It has an addition partition, too.
With Lion, I set up FileVault/complete HardDisk encryption/CoreStorage.
Last week, I started the Mac, got the starting screen that shows the user und promts for a password to decrypt the hard disk, but after typing the password and pressing enter, the Mac does not boot (Something like a "No-Passing-Through"-Sign appeared on the screen).
I started from recovery partition and varified disk with Disk Utility. This is the log:

The volume 42342140-D56E-4138-8DD3-78A32575FBB4 was found corrupt and needs to be repaired.
Problems were found with the partition map which might prevent booting
Error: Storage system verify or repair failed.
I tried to repair, but got the same log.
As the main partition is encrypted, no third party application can access it, repair it or copy file from it.
Before I give my Mac to TechSupport to replace the hard disk, I would appreciate of doing a useable copy/clone from the partition to get my data saved (I have time machine running, too, but it is not backup up everything and it is hard work to restore from there – so a clone would be best).
Best,
Stefan

I have discovered the solution and it involves an issue I suspected. After the restore of my old Time Machine Lion files to my new MBP running ML, the restore restored my computer back to Lion. After an install of ML, my computer worked perfectly except the fancy Scroll and zoom featured we all love from the trackpad. Ha already installed ML on other partitions and the trackpad worked perfectly on them. Even the guest login's trackpad worked perfectly but not the main admin account.
First thought was to create a new admin account and copy everything from the old admin to the new admin and then delete the old admin account. Hated the idea because all files had to be copied rather than moved.
So what was left to do. I had thought of deleting all the apple preferences from the library and replace them with the contents of the library on another partition in ML. First I deleted old preferences many of which were old Lion preferences. That didn't solve the issue.
I forgot that Lion and ML HIDE the user library so I was working on the wrong library. Discovered the Terminal command "chflags nohidden ~/Library" and I chose to reveal the user library on a ML partition.
Solution:
I booted into another ML partition. I guess that I could have booted into the new admin user account and changed the permissions to access the old admin users Library But I chose to boot
from another ML partition: copy ALL the com.apple. XXXXX.plist files and the folder BY Host. It has special hidden files. Other way is to copy the Preferences folder we'll say into the Desktop.
I then proceeded to delete ALL the com.apple…….plist files and the Host folder into the trash. Then I copied all the apple.com…plist files and the Host folder and then rebooted. And now my wonderful Trackpad works as mountain Lion intended it to work.
I'm leaving this solution because there's someone else in the MacWorld with the same issue.

What does the "Erase Free Space" function do?

in the disk utility, there is an option to erase free disk space.
what exactly does this do?

From Disk Utility Help:
"When you delete files by emptying the Trash, Mac OS X deletes the information used to access the files but doesn’t actually delete the files. Although the disk space used by deleted files is marked as free space, deleted files remain intact until new data is written over them. As a result, deleted files can be recovered.
You can use Disk Utility to erase the free space used by deleted files by having zeros written over the space once, 7 times, or 35 times. If you have a lot of free space on your disk, overwriting the free space several times can take a long time.
Erasing free disk space does not erase the other files on your disk."

Can you reliably erase data after HDD disc i/o error?

My HDD has failed with disc i/o error on my 24" Intel based iMac.
Does any one know if Disc Utility can reliably erase data despite the hard drive failure?
I'm in the process of disposing my iMac and want to make sure all my data is securely erased before doing so. Otherwise, I'll need to resort to physically removing the drive.
Thanks!

If you zeroed the disk using the security option (which you did) and it succeeded, then the bad sectors were likely remapped to spare sectors. However, you might want to check it periodically to see if the drive continues to develop bad sectors. If it does it's actually likely a mechanical failure in the process of developing.
I use a product called Scannerz to test my drives, and the repair procedure they recommend is to do what you've done but using only a single zeroing pass. After such an event occurs they recommend testing the drive periodically at increased intervals for a while to verifiy that more sectors aren't going bad. If they are it apparently indicates bearing wear and either the platter is wobbling enough to cause the heads to crash onto the platter or the bearings in the actuator arm are going bad with the same result. They have a fair amount of information on their web site at:
http://www.scsc-online.com
either in their how-to section or in the downloads section. I know I remember reading this stuff there but I don't remember which document or how-to article had the information.

If you reinstall Mac OSX 10.5, does it erase all your files and settings??

If you reinstall Mac OSX 10.5, does it erase all your files and settings, if it does, how would you install iMovie by itself, because I accidenatlly deleted imovie

jd087 wrote:

that depends what reinstall option you choose. an erase and install will erase everything. an archive and install will preserve user data and applications.
However neither one will reinstall imovie which is part of ilife which is separate from the OS itself. you can reinstall ilife only. there is no need to reinstall the whole OS. if you bought ilife separately then use the ilife DVD. if ilife came with your mac then insewrt install disk 1 that came with your computer, open it in finder and double-click on "install bundled software only".
