Securing external drives w/10.4.8

I have a Lacie 250GB drive - connected to my MBP via FW800 cable - that I use to backup my Home folder. How can I secure that drive so that, for example, someone else can't simply plug it into their mac while I'm out on a business trip and start having a picnic with my personal information?
I'd like a solution that works with the Keychain and Backup 3, if possible.
From what I've read in various Discussions, using (as a target for the backup) an encrypted sparse image on the Lacie might fill the bill. But I'm way over my head already! How do you create a spare image? Is there an option in Disk Utility that I'm not seeing or must I get a third-party app involved?
Or am I way off the mark?
Thanks. Any help would be greatly appreciated.

In the Disk Utility, click on the New Image icon in the toolbar or choose Blank Image in the Image menu. Next, choose AES-128 for the encryption and specify how big you want the image to be; if the external drive is in the FAT32 format, the disk image must be smaller than 4GB. A sparseimage file will automatically resize itself as needed, while a read-write disk image can have its size changed by converting it in the Disk Utility.

  • Latest security update and the disappearance of my external drive

    I'm sure you're going to tell me that one has nothing to do with the other, but after running the latest security update, the Iomega MiniMax external drive that's been connected to my TiBook for the last 3 years has all of a sudden disappeared from my desktop.
    System profiler sees it, Disk Utilities sees it. But there are a couple of things bugging me:
    - I'd never paid attention before, but both the System profiler and DU indicated that SMART is not supported
    - When I ran DU (off the OSX install disk) to try to repair the HD, I got the following message:
    +Invalid node structre+
    +Volume check failed+
    (these 2 lines in red type)
    +Error: The underlying task reported failure on exit+
    (this in bold, red type)
    +1 HFS volume checked+
    +1 volume could not be repaired because of an error+
    I think that was in red, too, but can't swear to it, as I'm totally rattled by now.
    Now, there is no system on the Iomega, nothing but precious photos and music (since the original HD on this TiBook could only hold 30 Gb), and I'm at a loss as to why all of a sudden I can't access it. Whenever I've come back from a trip, I just plug the external back in (via firewire and usb), and it would just show up, as if nothing had happened.
    Any ideas, any help would be, as usual, most appreciated.
    Thank you all.

    I realize I'm getting 'way off this thread, but wanted to post back. I brought the Iomega to work, plugged it into my iMac and… nothing. Running DU gave me the same results as posted above. Then, for want of a better idea, I pulled out the install disk for the iMac, started up off that and ran DU.
    Guess what? It went through its verifications, came up with problems and then proceeded to repair the external. And that wonderful little orange icon was there on my desktop at startup!
    There shouldn't be any difference; my guess is it just happened to pick that time to mount. Sometimes a HD with issues will not mount 10+ times in a row, then, for whatever reason, it does on the eleventh try.
    There's a new folder in the Iomega now, called "lost+found", weighing in at a little over a Mb and full of files ending with ".nib". Any idea what those are and if I need to keep them?
    Hmmm, Google search turns up this from wiki:
    Interface Builder is a software development application for Apple's Mac OS X operating system. It is part of Xcode (formerly Project Builder), the Apple Developer Connection developer's toolset. Interface Builder allows Cocoa and Carbon developers to create interfaces for applications using a graphical user interface. The resulting interface is stored as a .nib file, short for NeXT Interface Builder, or more recently, as a .xib file.
    Do you use Xcode?
    Another hit mentions iPhone, and another Corel. Don't know what to make of it in your case. Can you open any of the files? Any have same name as your data? Creation dates?
    I shall now proceed to back up before reformatting.
    Good plan.
    And check out the cost of a replacement here (they're a good bit higher than in the States.
    Ask yourself what your data is worth, and after it's gone, what you would have spent to have retained it. My guess is the answer would be a lot more than the cost of a HD.
    Do I want a SATA?
    Nope, TiBook doesn't have that interface.
    I liked this model because it also worked as a hub… There are so many flavors out there now!
    Indeed.
    er, ahem, that's a sheepish "yes".
    'Nuff said.
    A while back, thanks to you and other forum members, I'd gathered up the courage to swap out the original HD for the biggest one the PB could take, and had always meant to to a "backward" backup of the stuff that was on the external — or copying photos onto CDs. Needless to say, the task got put off until this scare. Won't be doing that again.
    I considered myself "lucky" the first time I lost data, as it wasn't too, too important, but it taught me a lesson I've never forgotten.
    So, once again, thanks for the hand-holding (you had also talked me through/encouraged me to deal with the tight hinges on the TiBook).
    You're welcome. Together with RAM and HD, that was the best thing I ever did for my TiBook.
    Love this forum!

  • Security Update - now can't connect to external drive - The alias could not

    Hi, I loaded the new security update and now cannot connect to my external hard drive connected to my Airport Extreme. It sees the network and tries to mount the drive, but they I get an error saying "the alias could not be found...." I can't get further.
    Anyone have any ideas? Or I can I set up the external drive again?
    Thanks!

    i'm getting the same error trying to connect to either my imac or a lacie 2big ethernet raid drive. the first time i got this error was after connecting my other ibook to the imac as one of my other users. since then, my main ibook throws this error on every connect attempt.
    weird thing is the mount succeeds. the shared files are accessible. the mount can even be "ejected". but each connect throws this "error code -35" popup. additionally, none of my machines has spaces in its system name or in its shared directories. just simple names like store2big, itunes, jeeeem, etc. most baffling.

  • Making an external drive secure

    I have 2 external drives. How can I make them sure? I have passwords for my start up disk, but if someone were to steal one of my externals drives that hold my backup clone, wouldn't they have open access to all my files?

    Unless the external drive is password protected, the files will be available to anyone who mounts the drive, even if they cannot boot it. The best security is not to lose the drive.
    Even your password protected startup disk is easily accessed by anyone with a modicum of computer knowledge.
    Again, keep the hardware itself secure. If you have very important data, you might consider a safe.
    In general it's best to consider that nothing is really secure. All you can hope to do is make it difficult and time-consuming for someone to access the data.
    If you use WiFi with anything less than WPA, your data are easily available to anyone who wants to get it.

  • Time machine on external drive will not back up itunes media file on a separate external drive. Have already reformated itunes media drive,dragged itunes media backup file from time machine (old copy) and removed time machine plist and restarted.

    Two external drives, one for time machine backups and a second (daisy chained firewire) for itunes media folder . Time machine fails to backup the media file saying could not be completed, with no error specified. Steps taken already include reformating drive with media, dragging older media backup file from time machine disc to media disc, and deleting time machine plist and starting time macine preferences upon startup. Media folder is approx 200 gb, mostly ripped dvd movies.
    Any help for this??

  • ESATA/USB Secure Hard Drive is not recongized

    Hi all,
    I got this cool external hard drive in my work and it have been workin great... until now.
    I had it connected to my computer and then my wife turn that computer into hibernation (ohh no), and since that I can't get my computer (any computer) to recongize it. When I connect it I enter my pin and the LED turns green (static) but the computer do not recognize it, it does not even say "found new hardware" when connecting it to a computer (with or without entering pin)
    Please help, can I recover my data?
    Best regards
    Per

    Hi,
    I had the same problem a few weeks appart with two 500GB eSATA/USB Secure Hard Drives. I had safely disconnected the drive but I only physically disconnected it hours later.
    After that, the disk wasn't recognized on any computer I tried it with (Windows or Linux, eSata or USB). After disconnecting the data cable, the led stayed green forever (usually it turns red a few seconds later).
    I was able to make it work again by performing a complete reset (but of course everything was erased and I had to re-partition the drive).
    Fortunately these drives are used for backups so I didn't lose any data. But it is worrying to know that we can't rely on it so much... It would be great to come up with a upgrade that would make the disk more robust for that kind of problems. I didn't find anything for this product on Lenovo's support website...
    Best regards,
    Nathalie

  • When I connect an external drive I'd like to run a program which is on it. How could I do that?

    When I connect an external drive I'd like to run a program which is on it. How could I do that?
    I tried automator, but without success.
    Thanks

    Interesting question.  Others have provided the direct answer (no, massive security hole), and a little time with a search engine finds various existing discussions of autorun-related topics (eg: here and here and here), and a link to the Do Something When tool, and there is the DeviceListener example in the Xcode kit and to adding a folder action where the volumes are mounted.  See the topics for details.   Haven't tried this stuff, though.

  • How to move itunes library .New vista pc &keep music on an external drive?

    I'm moving from a Windows XP machine to a new Vista machine. All my music is on an external hd that I conenct via usb. Before giving away my old lap I backup the itunes files named itunes.itl,itunesmusic library.xml, albun art work folder
    I installed itunes 7.2 and then I go to the edit preferences and change the music folder to f;//my music son itunes gets the music from my external hard drive.
    Then i copy the itunes files that i back up into the the c ;users itunes folder.
    WHEN i open itunes it start loading my library but suddenly stops and somtekind of error as file lock appears. son i unistall itunes an reistall it. but need to install it rigth so i can keep with my playlist etc.
    I aloso
    tried to add all my music to the new library. So i go to add folder to library and itunes starts getting some songs (i have more than 10000) but after a few minutes it suddenly stops and no songs were added to the library. and itunes freezes, so the only way to go ,is control alt delete ,stop itunes and start again.
    I triend adding folder by folder , my music is organized as example. each floder has artist album and songs but I have to many folders . i tried adding one folder each time it ,instead off adding the my music folder with all the subfloders and it seems to work but it is going to take me months to finish.
    does some one knows what should i do ? or why itunes sotps suddenly? or what is the right procedure i should follow to keep my music in the external hard drive and continue with my play lists.?it is like a new installation with all the music in an external hd, an I want to keep it that way.
    Does some one know if i have to do something with the ituneslibrary files befre copynig then to the new ditunes directory created with the new installation , in refering as permits or porperties ets?
    what i want to do is a clear new installation of itunes and keep my music in the external usb hard drive , but keep or restore my playlists and library that i back up before.?

    I do the same thing as you do...
    My music is on an external drive as to not use up gigabytes of storage that need not be used for media.
    There are a couple basic principles to iTunes that I believe you should know.
    1. iTunes is not a media storage program. It does not store your media "in iTunes". It simply is an organization tool for your media already on a hard disk.
    2. As iTunes is not a storage mechanism, it has no way to "know" whether or not the media that is listed is actually there. This is where the "design" of iTunes comes into play.
    I like to think of iTunes as a bread-crumb trail. The "music" in iTunes, isn't actually there. The bread crumb is the location on the external hard drive.
    If that bread crumb trail disappears (in this case the external drive you use). If said external drive is not plugged in, that bread crumb trail is not able to be followed. iTunes is "lost" and unable to find the media. The only way to remedy this is to place the media on your local drive.
    To address your issue of the library. If you hold down shift, you can select your library on your external drive. It will be a file with an .itl extension. The folder name will be your external drive.
    I go into edit > preferences > advanced and set my library to the correct location. Make sure you check the box "Copy to iTunes Folder when importing" (or whatever it says).
    You can't fix the issue of iTunes not seeing the media if your drive is unplugged unless you physically move the content to your OS HDD...Or any other HDD you use.

  • Can't Install Snow Leopard on external drive

    Hey Mac Addicts,
    I'm trying to install Snow Leopard on an external drive (Lacie Triple Rugged, FW800 USB3.0)  but keep on getting "Installation failed, can't copy the support files.
    My drive is partioned in to 5x100GB partitions, GUID partition scheme. I boot from my installation disk, choose my partition and hit install. The DVD spins and spins and eventually give me a failure. I've tried not installing the custom options (Quicktime 7, Rosetta and have even unchecked X11) but still get the same.
    The MacBook Pro I'm trying this from is running 10.6.8 and previous successful attempts at doing this were from 10.6.4, I'm thinking this is the issue, but would rather not have to clean install my machine and try again.
    If anybody has any idea's that'll be marvellous, as I am a little confused and lost, especially as I've done this before.
    All the best and thanks in advance.
    BigMik

    Two things,
    1: Use FIrewire
    2: Use Disk Utility to first Erase with Security Option Zero All Data, the entire drive, then setup the partitions
    3: If it doesn't work, then increase the size of the 10.6 parittion or reducing the partitions until it works.
    4: Also do all this from the Disk Utility on the internal drive, then try again from the 10.6 install disk. Apple might have pulled something.
    Also you can clone your present OS X 10.6 partition using the donationware Carbon Copy Cloner, however the external partition needs to be large enough for all the contents (recommended)

  • Emptying trash isn't freeing up any space on MacBook Pro or external drive. Time Machine is OFF.

    Yesterday, while using Final Cut Pro X, I noticed the program/my computer was starting to run slow--and then I was totally caught off guard by a warning that my startup disk was full. I checked Storage and Finder and both my MacBook Pro and external drive had less than 1gb of space each! I usually use Secure Empty Trash and have no problems...but for my drives to be full, it clearly hasn't been working for a few days, possibly weeks.
    I'm using a MacBook Pro (early 2011) and a LaCie Thunderbolt external drive. I'm running Mavericks (10.9.2)
    I am not using Time Machine. When I look at Storage under About This Mac, my Backups on my MBP and LaCie drive are both at zero KB.
    I read through the forums and tried going into Terminal and entering sudo rm -rf ~/.Trash ...but all that did was free up about 10gb on my external drive (I'd emptied upwards of 90gb from my trash).
    Right now I'm basically stuck with a slow laptop and very little storage space, which has slowed my work to a halt. Does anyone know how to fix this?

  • Can you restore an external drive using Time Machine

    I have my media libraries (iphoto, imovie, itunes) on a separate external drive connected to my mac. They are being backed up to another HD through my time machine backups. However, should my media external drive fail, is it even possible to restore the files to a replacement external HD using time machine? Would it be better to partition my time machine external drive and use half for time machine and the other half to manually copy/backup my external medial HD?

    Would it be better to partition my time machine external drive and use half for time machine and the other half to manually copy/backup my external medial HD?
    Bad idea, thats putting everything in once place. Worst premise for data protection
    Methodology to protect your data. Backups vs. Archives. Long-term data protection
    Everything is about 1. redundancy, 2. redundancy and 3. multiple storage platforms (DVD, multiple HD, online server archives ala a personal website etc.)
    The first realization is that your data on your computer is highly vulnerable
    The second realization is that you need a HD backup of your OS and data
    The third realization is that you need at the very least a secondary HD backup
    The fourth and final realization is understanding the fragility of any and all HD & ferromagnetic storage, and that vital data needs to be “frozen” on unassailable redundancies across multiple storage platforms including multiple HD, online backup, archival DVD burns comprising at the very minimum triple platform redundancy of data you have been working on for years or decades that cannot be replaced.
    The B.A.R. “rule” (backup-archive-redundancy)
    Backup: Active data emergency restore. Backups are moved from backups to archives; or from backups to the computer for restore or data retrieval.
    Archive: Active and static data protection with the highest level of redundancy. Archives are only moved from itself to itself (archived copies). Generally a “long-term retention” nexus.
    Redundancy: A fail-safe off-site or protected and “frozen” copy of your vital data and foolproof protection against magnetic degradation and HD mechanical failure. A likewise failsafe from theft, house fire, etc.
    Redundancy has two points of premise:
    A: redundancy (copies) of data archives.
    B: redundancy of data on different platforms (optical, online, magneto-optical, HD).
    Send your backups to your archives (as often as possible), and your archives to self-same redundancies.
    *When referring to backups and archives here, this is in reference to your data saved/ created/ working on,... not your OS, your applications, and your system information / settings,...which is the idealized premise for use of Time Machine as a system-backup after internal data corruption or HD-failure.
    Here we are referring to data backups and archives, not system-backups for restoring your OS-system.
    If your data on your hard drive is the cash in your wallet, a backup is your bank account/debit card, and an archive is a locked safety deposit box.
    Its easy to get your wallet emptied (corrupted) or stolen, your backup checking account is somewhat easy to get corrupted/drained or damaged, but your bunker security is in the lockbox inside the vault, where your vital data and archives reside. In the premise of preventing data loss, you want as often and as much as possible one-way transfers from your “wallet” to your safety deposit box archives; and further still a minimum of two copies of those archives.
    Highest priority (archives) requires highest redundancy.  In the premise of often copying data from backups to archives, backup redundancy plays a minor role.
    Long-term active file backups (a book, a major time-involved video creation etc.) requires double-active redundancies, preferably a minimum of Time Machine and an autonomous external formatted HD, so there are at least three copies of this data: internal drive, Time Machine, and secondary non-TM HD backup.

  • How best to move user folder to a Mac Mini + external drive

    I am streamlining my desktop computer setup. Whereas before I was using a PowerMac G5 as my primary desktop computer, I realize I am using my MacBook Pro more often, so in the interests of conserving space, I will be switching over to a Mac Mini connected to my AV system for hosting all my iTunes music, videos, media, photos, etc.
    Here is where I need advice. My PowerMac has a lot more media on it than can fit on the internal hard drive of a Mac Mini. I have already secured a 1 TB external drive which will be permanently connected to the Mac Mini, but I am unsure as to how to best go about copying my data to it.
    My initial thought was that I could move the iTunes music folder to the external drive using the library consolidation feature, and I could copy my iPhoto library to it, then point the respective applications to the new location. However, I want the external to act as my home folder where the OS looks for all my personal data, including movies, documents, etc.
    I know there is a procedure for changing your home folder's location to an external drive, but because of the limited size of the Mac Mini's internal HD, I would like to use migration assistant when I first start using the Mac Mini. Should I hold off on moving the home folder until after I have migrated, or can it be done beforehand?
    Anyone have any thoughts or ideas? Thanks!

    Thanks for the procedure. It seems very easy, but I am wondering about the consequences depending on when I do it. For example, let's say I first copy my entire home folder to the 1 TB external drive, set up the PowerMac to use it as my home folder, then use migration assistant to import my user accounts, applications, and settings onto the Mac Mini. Will it try to extract the data from the external drive onto the Mac Mini's internal drive? There won't be enough room for everything.
    As an alternative, I can move my iTunes library and iPhoto library onto the 1 TB external first, keeping the rest of my user data in its original location. Then it can fit on the Mac Mini, and I can do the migration, then move the home folder to the 1TB external once it's all up and running on the new computer.
    Which will work best?
    I had heard about people using a single drive as their home folder across multiple computers, but that is not the case for me. My MacBook Pro will become my primary computer, but I intend to keep it clear of media, whereas the MacMini will become my media server for my AV system in my living room. The 1 TB will be constantly connected to the Mac Mini, so there shouldnt be a problem with starting it up once the user folder location has been moved.

  • Where Can I Learn About Connecting an External Drive to My Airport Extreme?

    I'm having trouble find information on this. I want to know the pros and cons of connecting my LaCie drive to the FireWire port of my base station so that different computers in the house have direct access to it. I'd like to know whether there will be a big change in the data transfer rate, any security issues, and whether permissions will be assigned automatically by the computer creating new folders on the drive. Also, I'd like to know whether Time Machine works well this way.
    Any thoughts would be most appreciated.

    You're right about the USB. Must have been imagining things. Darn those meds. Thanks for the speed comparison too; I think I'll experiment a bit. Shame about Time Machine though. I thought I had read a post elsewhere on the discussion board saying that Time Machine recognized an external drive connected to a router. It may not have been an AEBS, and perhaps recognizing it doesn't mean Time Machine will back up to it.
    Thanks again for your reply.

  • Using an external drive with iMovie HD

    I just received and formatted my external drive. At first I chose Mac OS Extended (Journaled) and Zero out data. When I got info (⌘+I) of the drive afterwards, it had 79 MB being used, journalling? So I then Erased it and chose Mac OS Extended and now it shows 59 MB as being used, whatever for IDK.
    Does it matter which format I use for working with iMovie, journaled or not?
    In the Get Info window there is an Ignore Ownership option. I know it doesn't need to be ticked when an OS is going to be loaded on the drive but am wondering if I should tick it since the drive is only going to be used mainly for iMovie projects and no OS is going to be loaded.
    Should I tick Ownership or leave it off?
    I have iMovie projects that have not been edited yet and a iDVD project on my internal drive.
    Can I just drag and drop or copy and paste the iMovie projects to the external drives icon and delete the project from my internal drive to create a little more space? Is it simple as that?
    Same thing with the iDVD project after archiving it first? Copy/Paste,Drag/Drop and delete.
    I've got a backup drive but use SuperDuper! so I don't have any experience with using 'scratch?' drives.
    I've read elsewhere on this Discussion site that the finished iMovie projects need to be on the internal drive in order to transfer to and edit in iDVD.
    How and where do I move the project to from the external? Drag/Drop or Copy/Paste to my Desktop then Drag/Drop, Copy/Paste to iDVD, or some other way?
    Thanks.

    I am not sure zeroing out data on a SATA drives "marks" bad blocks/sectors. I think this may have only been on SCSI drives. I couldn't find a reference that it behaves this way on a SATA drive. Thus the only advantage being that it more securely erases files.
    The click and hold works the same on a PB!
