Can I erase everything on my computer?

I'll sell my computer, but want to clear the memory of my files and passwords. How can I do?

Reinstalling the operating system will take care of MOST of the problem, but to be completely safe, you need to replace the hard drive.

See the following quote from a wikipedia article

"Similarly, formatting, repartitioning or reimage a system is not always guaranteed to write in all areas of the disk.

http://en.Wikipedia.org/wiki/Data_remanence

I think the same if you do a clean reinstall of your OS, a skilled hacker could still recover some of your data.

See these discussions really scary:

If you can't replace your hard drive, then you might want to try a file shredder:

  • I can erase everything on my computer since I bought without a Vista DVD

    I don't have a recovery disk with my Toshiba Satllite with Vista Home. It was installed in the factory and I have the product key from the bottom of the laptop. The only drive I have is the CD to upgrade to Vista.

    Call you the manufacturer of the computer...

    Ask to speak to a technician. Ask the person to teach you how to access your recovery Partition and use it to restore the factory settings.

    Another way is to ask the manufacturer of your computer for a set of recovery disks. The cost is minimal, and you should have a set. All of the recovery disks will also restore your computer back to factory settings.

    Do not erase everything on your phone under the procedure of release.  If you have your phone set to backup Contacts on iCloud, they will be saved and then can be later reloaded on your phone after erasing it.  I just got two iPhone 5 and it worked well.  Also to do a full backup to your computer via iTunes and transfer everything what is not already saved if you are asked.  The only problem I encountered was that some applications does not and I had to manually reinstall the.

  • Can't erase my hard drive recovery utility

    Hello everyone,

    Huge disappointment a few hours ago. My system would not start. Rebooted from OS X Recovery and scanned with utility disk to find out there was a mistake not repairable in the hard disk which told me that I should restore with time machine. Fortunately, I had my backed up system and that's what I was doing. After the process, I found that my data was back, I have not all apps! No safari, no itunes, no store apple to re - install applications, nothing... Maybe I should have stopped here and ask for help, but given that my data has been backed up, I thought it wouldn't hurt to try the other option in the OS X Recovery: reinstall OS X.

    So I tried to reinstall OS X. It took a few hours, and when the system was finally restarted to complete the installation, it prompted a message saying that OS X could not be installed (don't remember why).

    Now, when I try to start the computer, it automatically goes to the recovery, and practically I can't do anything... I can't use time machine because the hard drive to the mac does not present as an option to install the system. It won't let me delete the partition that the system created to install the OS X either (about 1.3 GB)... the options for 'clear' are grayed out.

    I tried to erase everything, but I'm not power, and it seems that there is not much I can do, given all the options appear to be available... What a physical error in the hard drive? It was working perfectly before this happened, and the laptop has not left the office in between.

    The system is a MacBook Pro from 2012 (originally with the Mountain Lion and now ran on Yosemite). The hard drive is a semiconductor.

    All the miraculous solutions are welcome!

    Thank you!

    Should be explained a little more disciplined, please.

    For example: the system created to install the OS X is (about 1.3 GB) is not clear: 1.3 GB is much too small to install OSX on it, then of course, you can't go. And you cannot use the RecoveryPartition for anything other than repair or reinstall the disk 'real '. The Partition Recovery itself not even 1 GB by a long shot...

    Since you have the TM backup, what you can do is:

    in the recovery partition, open DiskUtility, select the disk (not the partition, but the disk with the name 'complicated': DiskUtility should give the size (128GB, 56 GB or other): then in DiskUtility choose tab partition, then the partition: 1 partition, OS X Extended (journaled), (Advanced :) button) GUID Partition table.

    a when you're done, exit DiskUtility, select install OSX then TM, or install it directly from TM.

    You can disable hibernation if it is enabled and you do not...

    When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

    -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
    -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
    -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

    You can control the amount of space your system restore can use...

    1. Click Start, right click my computer and then click Properties.
    2. click on the System Restore tab.
    3. highlight one of your readers (or C: If you only) and click on the button "settings".
    4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
    5. click on OK. Then click OK again.

    You can control the amount of space used may or may not temporary Internet files...

    -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
    -Click OK.
    -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).

  • My rocket downloaded everything on my computer.

    I just got my Sansa for Christmas. Love it, think it's great, and it has some pretty cool features. I plugged in my computer yesterday, transferred all my songs in iTunes to WMP (I didn't immediately put videos or photos) and let it sync. I was wondering why it took a full day just to synchronize the songs of 500 or more, until I realized that the downloaded Sansa every single photo, music and video files on my computer!

    Now I have about 5 000 photos, 300 additional songs and 20 videos, that I'm not on it. So my question is, how to remove the extra stuff alllll (preferably without having to delete them all one by one on the player) and make sure that my Sansa download all the files in my files again?

    Your problem is Windows Media Player, which is set to Auto-Sync. Depending on your version, the settings are in different places, but connect the Sansa and then click Rip, Burn, sync etc. around and make any manual or sync music just for some files.

    If you want to just start again, on the "rocket" under Settings/Control Panel is Format, which will erase everything you have added to the Sansa (it will not disturb the firmware).  So keep an eye on Windows Media Player and what he adds.   At this point, since WMP has already indexed all the media on your computer, you will need to tell it to forget its index - but make sure that it does not remove the files too!

    The real way to avoid this kind of madness is to change modes (under Settings/Control Panel) USB - MTP Media Transfer Protocol, which connects with WMP - Meteorological Service of the Canada, which makes the work of Sansa as a flash drive. (You will see two drives, the internal memory and the slot for card, computer or workstation). Then, you can simply drag-and - move folders in the Sansa and see exactly what you get. If you like playlists, you can make them with Winamp in MSC mode.  Personally, I'm a Windows Media Playa hata.

    Hi strayschool,

    Have you tried to put the iPad into DFU mode? Here's how...

    1. Launch iTunes on your computer and connect your iPad to your computer.
    2. Power Off the iPad by pressing the power button on the top of the iPad for 3 seconds and then drag the slider to power it off the coast.
    3. Once it is off, press and hold the power button on the top of the iPad for 3 seconds. After 3 seconds, press on and hold down the Home button and the Start button / stop for 10 seconds.
    4. After 10 seconds, release the Power button but now hold the Home button for 5 seconds. Then release the Home button.
    5. The screen stays black and the iPad should now be in DFU mode. ITunes on your computer should now say that it detects your device and you can restore it.

    If you see the "Connect to iTunes" screen then you are in recovery mode (not DFU) and you should try the above steps again. But maybe the recovery mode just need you to bypass the password protected iPad and you can restore... Give it a shot.

    Hope this helps!
