Will the hard disk be erase when I update to Lion

Will my document be erased when I update to Lion?

No. Your user accounts will be maintained.
HOWEVER, that doesn't mean you shouldn't backup first, in case anything goes wrong (and if you don't backup and things don't work out as intended, you've only yourself to blame!).

  • I want to give away or sell a 6500/250 running 7.6.1. How can the hard disk be erased so that the data are gone, not recoverable? thanks, LifeisRich

    I'd recommend that you check for Mac User Group(s) in Orange County.  That's where you'd likely find a diehard Mac fanatic who might want to add your 6500 to his/her collection.  Even if you got nothing for it, it would be better than e-cycling it.  I upgraded my 6500/275 with what was a "large" hard drive at the time (15 GBs), maxed the memory at 128 MBs, installed the 512K L2 cache card, a better ATI Rage Pro PCI graphics card, a USB PCI card, and an internal 56K modem.  With it running OS 9.1, it did all of the pre-OS X stuff I needed it to do.  As I previously mentioned, it's a nice-sounding MP3 player.  Internet Explorer 5.1.7 (the final release from 2001) kept it useful for surfing the web up until 2005, when it became too outdated/incompatible with many web sites.  Unfortunately, the demands of the internet and the need for a modern browser, as well as faster processing to digest it all, are what retired many older Macs from active duty.  So my (2) 6500s and (3) 6400s (same tower design) sit in storage.  There is one concern that I'll pass along: The motherboard has a 4.5-volt alkaline battery, that's a small, black plastic cube, secured in place by velcro.  If your 6500 has been disconnected from electricity for a long time, the battery will undoubtedly be dead.  Unlike the many Apple computers that used a small ½AA lithium battery (that I've never seen leak when completely dead), the 6500's battery can and usually does start leaking.  Because the motherboard sits vertically oriented on its side edge when installed, the leaking battery will drip alkaline solution down the board, corroding any components in it path.  I've seen motherboards ruined from this.  If you're going to give it away or sell it, you might want to pull the motherboard (remove the two machine screws on the rear I/O panel, next to the pull tabs).  Slide out the board and unplug the battery's small connector (has red & black wires), then lift up on the battery, while holding down the "toothed" velcro mount with something non-conductive, like a popsicle stick.  Once it's free, dispose of the battery.  If you're interested, a replacement can be purchased for about $5-$7 from battery specialty retailers - it's a Rayovac 870 or 871.  Even if you don't replace it, removing one that will eventually leak is a good idea, (hopefully) before any damage is done. 

  • Sleep Question when "Put the hard disk(s) to sleep" is unchecked

    In the Energy Saver options, I unchecked the "Put the hard disks to sleep when possible" option ... what happens if I close the lid? Does that option get overridden and the hard drive goes to sleep?
    Will I be safe to move my mbp around in my backpack when I travel? Or do I have to shut it down totally? I tried finding the answer but couldn't find a real response.
    I just want to know if the laptop's drive stops spinning and I can move it around safely or if I should always turn off my mbp when I put it in my backpack. Thanks for any answers.

    > what happens if I close the lid? Does that option get overridden and the hard drive goes to sleep?
    Yes, it's over-ridden, the heads park and you can move it around happily
    Make sure it does actually go to sleep and not hang up on some run-away (BootCamp) process or similar ... you can tell by the noise. If it's not silent within 10 seconds of the lid closing open it up again and check Activity Monitor.

    i use windows and i got my hard disk replaced now when i try to sync wirelessly my ipod detects my computed as being a different one how can i make it forget the old one?

    You will have to sync it to the new one, erasing the current content from the ipod and replacing it with the content from the new drive.
    Make sure you have copied everything from your backup copy of your computer back to the new drive first.

  • Recovery of Factory Default Software or Erase the Hard disk

    I'm tryiong to wipe my laptop (Satellite A305) clean and reinstall Vista using my recovery disk and the Toshiba Recovery Wizard. When I get the the point of no return I have 2 options, either Recovery of Factory Default Software or Erase the hard disk. I've tried to use the first option (Recovery of Factory Default Software) before and it didn't wipe the virus I have on my computer off so I want to try the second option (Erase the hard disk) but i'm not sure what will happen

    To rid yourself of a virus, you should delete all the partitions and overwrite all of the sectors on the hard disk. Those bugs can hide even in other partitions.
    See the section Recovering the original factory image (recommended recovery method), which begins on p. 62 of the User's Guide.
       Satellite A300 Series User’s Guide
    That Guide most likely applies to your computer. But if you reply, be sure to give us the complete model number. I've noticed that sometimes Toshiba modifies the Guide.

    Hello, I changed my Imac hard drive which no longer worked. I installed a hard drive
    Western Digital 500 GB 7200 rpm SATA3 WD5002AALX 32M Black. Sometimes I see the hard disk in the utility on the Starter CD, but access seems very slow. By cons when I want
    install OS X 10.4.2 on the hard drive, I do not see the disk. What is the problem?

    Thanks for the help
    I started on the installation CD OS X 10.4.2, I used Disk Utility
    to partition the disk according to the document that you have proposed. unfortunately
    I have not succeeded. When I partition the disk, even if I called it Macintosh HD, it
    does not keep the name and it shows disk0s3 instead. I did an erase on disk.
    When I mount the disk it tells me that I must repair. When I tried to repair, I got
    the following message:
    Volume check failed
    The underflying task reported failure on exit
    1 HFS volume checked
    1 volume could not be repaired because of an error.
    I also had a message:
    Invalid b-tree node size.
    Note: The disc is new, but it has already been formatted on a computer Imac 27 inch 2011 OS X Lion.
          I used a USB 2.0 to SATA cable to adjust the formatting.
    What to do to fix it?

  • Can I access my files stored in the hard disk connected to airport extreme when I am away? how?

    Can I access my files stored in the hard disk connected to airport extreme when i am away? How?

    You can't technically. iPads cannot directly read HDDs like a computer can. 
    You will need an app liie FileBrowser to do this. Of course all file operations will be done through the App itself.

  • "Put the hard disk(s) to sleep when possible": How to Exempt One Drive?

    I have a Mac Pro with 4 internal hard drives, 2 external hard drives, the built-in SuperDrive, and a new Pioneer BDR-205 internal Blu-ray drive. Here's the problem: If the "Put the hard disk(s) to sleep when possible" option is enabled, when the system puts the BDR-205 to sleep, it will never wake up unless the computer is shut down and restarted. (Basically, it disappears from the System Profiler and can no longer be accessed.)
    If I turn off the Energy Saver "Put the hard disk(s) to sleep when possible" option, then the BDR-205 never has a problem -- but then none of my other drives ever go to sleep, either.
    Does anyone know of a way to exempt a specific drive (or drives) from being put to sleep by the "Put the hard disk(s) to sleep when possible" feature? I've found where the settings for this feature are stored, in \Library\Preferences\SystemConfiguration\com.apple.PowerManagement.plist (the setting is Disk Sleep Timer -- 0 = never sleep, any other number = how many minutes before a drive is put to sleep), but I can't find where there might be some undocumented option to allow us to say, "Don't put THIS drive to sleep". It seems silly that this option is an all-or-nothing proposition.
    Anyone have any ideas? Thanks in advance.

    I am having the same difficulty. A way to exempt a specific drive from sleep would be most useful.

  • When i import movies from my iPhoto app to my iMovie app does it make a copy (thereby using double the hard disk space) or does it link to my iPhoto app? The reason i ask is i want to archive all my videos from iPhoto/iMovie. HELP!

    When i import movies from my iPhoto app to my iMovie app does it make a copy (thereby using double the hard disk space) or does it link to my iPhoto app? The reason i ask is i want to archive all my videos from iPhoto/iMovie. Do i need to archive the movies in iPhoto AND iMovie? HELP!

    Hi - I'm having the same problem with freeing up space on the HD. If I can't free space if I'm using any part of the clip, how can I split up the clips so that I can discard the part I won't use? This is crazy! I have only 4 GB of free space left!
    Also, I've tried to transfer the project file to my external HD but I keep getting an error saying I can't transfer it. I've been told this is because I don't have enough space on the HD for the transfer. I tried a similar transfer with another computer with plenty of HD space but the same error occurred. Is there a way to break up the project file into small pieces for the transfer (I'm thinking the whole movie file is just too big)?
    Thanks for any info!

  • NEW to TIME MACHINE - if files deleted, will it be missing in the hard disk

    i probably know that this is a silly question but here goes:
    i've backup my hard drive into my external hard disk using a time machine.
    if, i deleted the files in my mac. will it be missing in the hard disk too?
    because, i am already low on space and would really want to delete my important files that already backed-up.
    thanks!

    YES! Not immediately, but sooner or later, Time Machine will delete it's copies of things that are no longer on your system. See #20 in [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of this forum).
    Depending on the circumstances, the copies may be deleted in as little as 24 hours.
    because, i am already low on space and would really want to delete my important files that already backed-up.
    Backups, especially Time Machine backups, and extra space are two very different things.
    Your best bet is to get a larger HD for your Mac, so you can keep all the originals there.
    Second best is a another external HD; copy some things to it and delete them from your Mac, and let Time Machine back up both your internal and the new external.

  • ? appears on top of the window when I open the hard disk

    When I open the Hard Disk I get a question mark on the top left corner.  I'm including a screen shot.
    Please advise.  What can it be?

    NO.
    Have you tried clicking on the camera icon on the menu bar?
    That should generate this window:
    Click on Browse.  Navigate to your desktop and select the desired screenshot.  Then click on the Insert Image button.
