Clearing hard drive data

I am giving away my G4 - but naturally I want to erase all personal data. What's the best way to clear absolutely everything except the OS and applications?

Hi, Daniel -
That's very difficult to do as you have described it. Individual data files can be dragged to the Trash and the Trash emptied, but a reasonable savvy user can recover most of such with little effort.
The simplest, more secure way to get to that end is to deep-wipe the drive, erasing everything on it; then re-install just the OS. Installation of applications can be left to the new owner's discretion.
It is good practice, both for reasons of courtesy as well as legality, to also include all appropriate disks - this should include install disks for any applications included with the machine, as well as disks for any OS installed that is a generation or more newer than the one(s) that originally came with the machine.

  • I am migrating to a new iMac via TimeMachine back up.  My iPhoto libraries are on external drive.  I'd like to migrate only the internal hard drive data to the new internal Drive then just plug in iPhoto library drive.  Is this going be a problem?

    I am migrating to a new iMac via TimeMachine back up.  My iPhoto libraries are on an external drive.  Both drives are backed up on Time Machine.  I'd like to migrate only the old internal hard drive data to the new internal Drive and then just plug in iPhoto library drive to the new iMac.  This would save having to transfer several hundred GBs of data.  Will this work using Set Up Assistant?

    Your user account on the new Mac must have a different UID than on the old one.  See the pink box in Problems after using Migration Assistant for an explanation.
    You'll need to change the permissions on the iPhoto library on the external HD.  Do a Get Info on it, click the padlock at the bottom of the Sharing & Permissions section of the Info window and enter your Admin password. 
    Then click the plus sign, select the user account you want on the next screen, and click Select.   Then change Read only to Read & Write for that user via the little arrows.  Finally, click the "gear" icon and select Apply to enclosed items.  That may take a few mintutes on a large library.

  • Use time machine to save both the iMac hard drive data & an external one

    Can i program time machine to save both the iMac hard drive data & an external one

    Yes, but it's not advised because it's placing too many backups into one hardware basket, also it will greatly shorted your TimeMachine states where you can go back in time to undelete a file.
    It's better to have two backups, each on seperate hardware of each drive.
    So if you have a boot drive and a external drive, you should have a clone drive and TimeMachine drive of the boot drive, and a backup drive of the external drive. (or two depending how valuable the data is)
    If you drop a drive, or knock it over while it's running, all the data could be lost.
    With only TimeMachine as your backup, if you drop or lose it, or if it gets stolen, it takes two backups with it.
    A clone and a backp of the external drive stored safely off site is ideal, update it once a week or bi weekly as needed.
    A clone is bootable, and is exactly like your boot drive, up in seconds.
    A TimeMachine can only boot to restore to a new drive if your boot drive dies for some reason.

  • Help! Need to recover lost hard drive data after creating a partition!

    So, I'm the world's biggest idiot, and I was trying to reformat my hard drive so that I could bring the documents from my Mac to my PC.
    All of the docs were perfectly organized in folders and subfolders a long time ago, and once that had been done, I deleted everything off of the MacBook itself. I never thought I'd have to move all of the docs to a PC, but alas, nothing ever goes the way we plan now does it?
    Anyways, I created a FAT 32 partition not realizing it would delete everything I already had on the hard drive, so now I need to recover all of that.
    Is there ANY way that I can recover all the data I lost?
    Pls respond.

    When you create a partition, the partition is the erased so all content is lost.  There are data recovery services that may be able to recover the material, but they are very, very expensive, if they can even succeed with this kind of erasure.
    Check and see if there are any hard drive data recovery services in your area.

  • Powerbook Hard Drive Data Recovery

    A few months back, I bumped the desk that my Powerbook was on pretty hard. The laptop did a bounce, the desktop locked up, and that was it. Whenever I attempt to boot up the drive, it makes god-awful sounds, and the farthest I get is the grey Apple logo - no spinning wheel. Sometimes just a blank grey screen. Seems pretty clear that it's a physical problem, as if the hard drive can't spin. I have no idea what this means for the data - if it could possibly still be in tact and retrievable (no, I don't have it backed up, and yes, I know that's a no-no).
    I tried hooking up the Powerbook to my desktop in Firewire target disk mode, but the screen just stayed black after powering on. I tried booting from my DiskWarrior 3.0.3 CD, but it will not look at the hard drive, because it's the boot up drive.
    The prospect of a home remedy looks pretty hopeless at this point, but if you know of anything else I can try, please let me know. And if not, I'd appreciate it if you could point me in the direction of a reliable, affordable service company that might be able to assist. Many thanks.

    if the drive makes noises, problem is likely with the hardware and running utilities may not be able to fix it.
    if possible, get a qualified technician to check internal connections or possibly remove the drive and connect it via external enclosure/adapter

  • Good Hard Drive Data Recovery Companies?

    My Powerbook G4 Seagate 100gb hard drive recently crashed. I am a little desperate. I have been calling many different ones and not sure which to choose from.
    Any suggestions or recommendations or experience? This is a really confusing and frustrating process. I'm afraid to send it to a bad place and risk losing the data, but also worried about spending a couple thousand dollars when I don't need to.
    I was told that based on the sound of the hard drive that the heads crashed and that the head is broken. It hasn't been opened or anything. When I heard the sound, it sounded like a very faint clicking, almost inaudible. No software will work cause my hard drive is not recognized by anything, even in target mode.
    I have contacted DriveSavers (very, very expensive), Lazarus Data Recovery, DTI Data, OnTrack Data, and looked at many, many website pages.
    DTI DATA offered NO DATA, NO CHARGE, plus free evaluation and a fixed price, they seemed reasonable and confident on the phone anyway. For a head crash recovery, they said $1195.
    DriveSavers was very expensive. $225 attempt fee and said they would cap the price at $2000. They have clearly an amazing reputation and it seems like they could recover it. But they were a little weird, like used car salesmen telling me I had to hurry and decide because the price was only good for 7 business days. But, I haven't seen any posts saying they didn't recover anything.
    Lazarus was very, very nice and friendly and I liked them a lot, very nice and patient with me, explaining everything. Spoke to the technician. Much less expensive. $225 if they need to take it to the clean room. They said they would first try to clone the drive and avoid the clean room to save me money, but it sounds like they will need to go to the clean room. Their upper price range was about $600-$800. Much more affordable, but after scanning the web, I saw some people thought they were fantastic, miracle workers, others were not so enthusiastic.
    OnTrack had a $100 evaluation fee and a range of $400-$2400, but said most likely $1600. I couldn't ask details because the person on the line wasn't a technician.
    Anyone know who to go to? Or others? Help!

  • Using Time Machine to restore external hard drive data

    I have been using a Mac Mini running 10.6.8 for years as a media server.  I have always been very careful to maintain backups of everything, and the inevitable did happen - the hard drive containing all my media did fail.
    To clarify my set up, my Mac Mini internal hard drive is insufficient to store all my media, so I have been using an external 2TB drive to store it.  I then set up Time Machine to back up both the Mac Mini and the 2TB external drive to a second 3TB external drive.  Now that the 2TB drive with my media has failed, I seem to be having problems restoring all the media from 3TB drive.  This is because the Time Capsule interface is designed to display finder windows at various points in time so you can go back to when your missing files existed and restore them.  The problem is that I need the entire contents of the dead 2TB drive restored to a new drive, but I can't open a Time Capsule window that shows the contents of the old drive.  I have tried opening /Volumes in a finder window, then invoking Time Machine, but my dead hard drive does not show up in the list of volumes.  When I open the 3TB drive in a Finder window I can clearly see that it has backups of the 2TB drive, but they are spread out among 83 different snapshots of various dates.
    How can I use Time Machine to easily restore the entire contents of the dead 2TB external drive to a new external drive?

  • How to clear hard drive?

    Hi there
    Soon I am giving my powerbook 12" to a friend. How do I clear off my hard drive of all my personal data (i.e., restore back to original)
    Thanks for any help you all can give me.

    Actually, there are only three options available for a secure erase. (I wondered about that "17-pass" option since it doesn't exist). There is the "Zero Out" option, the "7-pass" option which zeroes out your data seven times, and then the "35-pass" erase that I mentioned which zeroes out, of course, thirty-five times.
    Now for the most infamous answer of all to your new predicament. One that I always give out. Target Disk Mode.
    You can do this by connecting your PowerBook to another Mac capable of running/installing the version of Mac OS X that's on your disc. Trouble is, this can only be done--because you have the original discs, not retail versions (or are they retail?)--on a similar model PowerBook. (Or if you have retail versions of the disc, since that runs on any machine).
    Though I wonder if it would work if it detects a compatible system, your PowerBook, and goes through with the installation process.
    Long story short, Target Disk Mode allows you to do many things, but in your specific case, now that I've gone into it, it might not work with original restore/install discs. (That's a first for me... giving a solution that won't work because of a rare stumbling block).
    Target Disk Mode is usually for transferring files, but you can also do it to install software to other computers that may have a faulty optical drive. For instance, if you wanted to install, say, iLife '08 on your PowerBook, you connect it to another Mac with the disc running, and then under Target Disk Mode, select your PowerBook as the destination volume.

    You know, you can do a simple method of deleting your files. Any files that you created yourself and know you did, simply put those in the trash. When you've found all your files, do a "Secure Empty Trash" from the file menu instead of the regular empty trash method. The only other thing I see that would need to be deleted are preference files (this is more risky because if you throw something out that the system needs, there could be conflicts... back in the days of Mac OS 9, it was easy to just pick and choose things to throw out. Not with Mac OS X) from things like Safari, iTunes, iPhoto, and any other place with personal info, like Address Book, iCal, etc.
    The other big thing would be your user account itself. You'd have to rename it (the short name can't be changed without using third-party software), change the password to something else or just leave it blank so your friend can use it. The problem there is that even though the password is changed, I've found that the system will sometimes look for an original password for things like Keychain Access, etc. So your friend might want to install something new, or could be just working in Safari, and a pop up dialog box might come up asking for a keychain password or admin password (other than the new one).
    So I guess the real thing to do is completely reformat your hard drive to pack it all up and make it clean and usable from the start. =(

  • Time Capsule Hard Drive Data

    Of course my Time Capsule has failed, but the hard drive is fine. I can easily mount it and see the 3 partitions. Problem is, I cannot access the data on the storage partition. "you don't have permission... etc". I have googled this for hours and I cannot find anyone having this problem. Surely there is a simple way to access the data on a fully functioning TC hard drive without purchasing a new TC and then swapping the drives.
    Does anyone know how to do this or could someone please post a link to someplace that does?
    Thanks

    Is this a Time Machine backup you are trying to recover or actual files?
    When you used the TC did you have disk password set? Most people leave it to device password but if you increase the security level to disk you have changed the permissions when on the TC.
    Normally you should just be able to change the permissions in the normal way.
    eg on Mavericks.
    http://support.apple.com/kb/PH13799
    If you need files and have windows running.. windows can generally see the files as it is rather less than interested in permissions.. it is often a quick and dirty way around the problem.
    The actual command line for changing permissions..
    http://www.chriswrites.com/2012/04/how-to-change-file-permissions-using-the-term inal/
    You do realise how dangerous doing command line stuff tends to be, I hope!!
    What size drive and what era TC did it come out of?
    If you are in Australia I could help you. TC shells are something I generally have loads of.
    And getting a new shell can still be a good way to go.. buy a second hand TC of the same model.. change hdd.. then you get your files back.. you can sell it on ebay again when you are finished.

  • External Hard Drive Data Recovery

    Hello Apple Support Communities!
    I have a Western Digital 320GB external hard drive and it currently has 0 bytes available. This has prevented me from even viewing the hard drive on my finder window. I can only see it in disk utility. I have tried repairing the disk and verifying it but neither has worked in letting me view my files. I use the hard drive for movies and now i can't see them! Can anyone recommend free data recovery software so i can delete a few files so that i can view my hard drive? Thank you!

    I found a way to sort of mount the drive and consequently do a data recovery.
    What i did was highlight the 'iphone-dump.img' and opened it with 'Disk Utility'. Inside of 'Disk Utility', I double-clicked the 'iphone-dump.img' icon and low and behold, it split into two drives, despite it giving me an 'Unable to attach 'iphone-dump.img' (no mountable file systems)' message at the same time.
    I wasn't able to do much with it in 'Disk Utility' from there on, so I opened 'Data Rescue III' and it became available to scan as a 'Virtual Interface' called 'Apple read:write'. I performed a scan and was able to locate my missing photos. It took a while because there were several duplicates of older photos. I think this is because each time I've restored the phone from a backup, data has been placed in a different location on the hard drive. Therefore, it has not overwritten these very same photos that have been on most of my backups for some time.
    I wasn't able to find my missing voice memos from the 'QuickVoice' application though. They appear not to be there. I found the existing ones from the recovery. They must be somewhere surely? Maybe the photos are stored in a different way since the photo application is a default app and 'QuickVoice' is a bought app.   ?
    Ideas anyone

  • Hard drive data cable issues

    I have a 2010 13" Macbook pro. It was refurbished when bought in 2011, and I've had it since May of 2011. The first time I had the flashing folder with a question mark was about a year after it was bought in summer 2012, and the data cable connecting the hard drive and motherboard was replaced. I have now had the issue two more times, once in March 2013 and again March 2014. All three times I had the flashing folder with a question mark, and all three times the data cable was the issue. While I am glad the issue has not been the hard drive itself, I am really peeved that I keep having this issue, and have to be without a computer for at least a week while it's being diagnosed and repaired.
    I read some other forums and the cable seems to be a fairly common issue, but I am wondering why I have had this issue 3 times in the last year and a half. I keep my computer on a cooling pad because I thought the heat caused the problem the first time, and I take very good care of it. Does any one have any ideas what could cause the data cable to have issues? Could it be something I am doing, or have I just been unlucky and gotten faulty cables? I don't want to have to replace this every year, it's getting a little ridiculous.
    Thanks in adavance for any input!

  • Hard Drive Data Transfer rate setting

    I am looking at upgrading my MacBook hard drive, but the drive I wanted to get is SATA-300, and I want to set the data transfer speed to 150 MB/sec to reduce the power draw of the drive without changing performance much. I know in Windows you can do this in to BIOS settings. Does anyone know how I would do this in Leopard? I assume it would be Terminal commands.

    As far as I know, they were just talking about Laptop drives only. It was a great article with lots of detail.
    I am trying to find the article I read on setting BIOS, but pages that carry the info on Laptop power consumption that I was reading were...

  • Crashed Hard Disk! What is the Hard Drive Data Recovery Service, & why wasn't it offered?

    I thought I had purchased the best extended warranty available.  Apparently the 3-year warranty I bought didn't include the Hard Drive Recovery Service.  I can't help but wonder why it wasn't mentioned when I bought the extended warranty. Now I have a trashed HD, and am looking at where I go from here.  I was told I should send the drive back to Toshiba... the manufacturer... for the most secure data recovery.  WHAT NOW?      who can steer me toward the best solution.  Of course, I don't have unlimited funds... and someone said it would probably cost $500 to $1000 to recover the info on my HD.  Arrgggh.  Help.
    This is a TouchSmart Tx2 laptop... not even a year old.  Under original warranty and has the 3-year extended warranty.

    I will check out your link...http://lowcostrecovery.com/pricing.html 
    Do you know anything about carbonite?  Perhaps had I gotten that service, I wouldn't be in this position.  I do back up a lot, when I'm at home.  However, we have been traveling for a coupe of months... and I'm a photographer.  Poof.  photos.   Important ones!  The tech who looked at my drive after putting it in an enclosure said he didn't "see" any files on it.  He said he HOPED I could get them recovered.  Gave me a sick feeling, as he didn't seem very hopeful that even data recovery would work. 
    Thanks for your replies.

  • My MacBook Pro's hard drive data recovery

    A short while ago, my macbook pro wouldn't boot. I took it to an apple store close by and they said they had to reformat the hard drive. They promised they'd try to retrieve some files. Sadly, only old files were recovered, I lost all my applications, photos, and music, and school work. Is it possible to recover the data that was on my previous hard drive? I'll appreciate any information. Thank you.

    If they've formatted and reinstalled on top of what was already there, it's gone. If they had pulled the old drive and you still had it, there might be a chance. This is why backups are important.
