I havve a segate external hard drive that I would liketo store sensitive data on. Is there a way to require a password to enable mounting?

Yes, by configuring it as an encrypted drive via Disk Utility.

  • How to password protect external hard disk drives

    Hi All,
    I have purchased and external USB port hard disk. The problem with it is anyone just plug it to thier computers USB port and use it as we use our windows explorer to browse the filesystem. However whenever I plug to my computers USB port it should prompt me for a password and once authenticated it should allow me to browse the filesystem of my external hard disk. How can I achieve this using java ?
    Thanks & Regards,
    Kumar.

    If you really want this to work properly, you will have to write a DLL for Windows that will intercept the appropriate filesystem call and prompt you for a password. Otherwise, another option would be:
    Create a standalone Java application that will read/write from the hard drive
    Use Java Cryptography extension for all read/writes to the hard drive (encrypt onto hard drive, decrypt into memory or internal hard drive)
    Have your sign-on required to use the Java application (and hence, decrypt the contents of the drive)
    Use passphrase-based symmetric encryption so that the password can be the actual key for the encryption/decryption (or if you want, have that key unlock a larger symmetric key also encrypted on the drive)- Saish

  • Password Protect external hard drive, it hasn't worked, why?

    Hi, I've surfed around and read how to password protect an external hard drive and I encrypted it, etc as told.
    However, and this will likely show my ignorance but isn't that the point of asking a question...
    The thing is, it's made the disk image that requires a password, but the hard drive can be ejected and put in and accessed without a password. The disk image is protected, permanently there (so maybe now it's taking up space on my hard drive, and the actual external hard drive is the same as it ever was and can be accessed without any password.
    Is there something I've done wrong, or something I'm not understanding about the concept?
    Thanks in advance.

    Hi-
    Welcome to Discussions!
    Double clicking the disk image should respond with a password request.
    Does yours work that way?
    If so, you didn't do anything wrong, as far as the encrypted disk image goes.
    That's about all that you can do.

    To encrypt the entire drive and make it inaccessible without password, this might be what you want:

  • Password Protected External hard drive

    I have a password protected external hard drive that I want to format so I can give it to a friend. When you format the drive does the password protection also get erased? Is there anything essential that I need to know before doing this? Thanks for your help!

    Welcome to Apple Discussions!
    If it's a WD MyBook, I'm not sure. I formatted and partitioned a MyBook for a friend, but was never able to get rid of the password protection so we just left it. It may be possible to do it, but I don't know how. Definitely check it out, and if the password is still required, be sure to pass it on to your friend.
    Good luck!

  • How to password protect a numbers document

    I'm trying to figure out how to password protect a numbers document.
    My intention is to load this document onto a website, but only want authorized persons with the correct password to be able to access.
    Any ideas??
    Thanks

    I am using Numbers 08
    And the Numbers User Guide, supplied with iWork '08, make no mention of password protection, which was introduced in Numbers '09.
    Looks like the best option is Wayne's second suggestion—open via File > Print > PDF > Open in Preview, then Save the resulting PDF document with encryption turned on.
    An alternate, if you want the recipients to receive a copy of the Numbers '08 file, and to be able to edit that file, you could enclose it in a secure disk image file.
    The basic procedure is to:
    Use Disk Utility to create a new, blank, sparse disk image, assign a password and save.
    Double-click the .dmg file (and enter the password when requested) to mount the disk image on your desktop, then Save a copy of your file to the (open) disk image.
    When done, eject the image, and upload the (encrypted) .dmg file to the website.
    Detailed instructions may be found in Disk Utility's Help files.
    Launch DU (found in the Utilities folder in Applications), click the Help menu and choose Disk Utility help.
    Go to the index, scroll to and click Security, then click a title similar to "Protecting confidential documents in a secure disk image." (a search on 'confidential' should also take you to a list containing that title.)
    My version of DU is old enough that sparse images hadn't been introduced, or I'd post a copy of the article here.

  • How to password protect sensitive info

    Hey all,
    I have an Imac that is shared by the family. Occasionally, the kids move or delete things that I need for work.
    Can anyone help me with how to password protect specific folders so that the Imac is open to use but some files can not be accessed without a password.
    I would settle for a "hiding" program so they can't delete what they can't see.
    Thanks

    You can use Disk Utility to create encrypted disk images of your secret folders (menu File > New), also encrypted sparse images that can grow as you add more data to it.
    But the different User Accounts for each member of family is by far the most friendly and natural solution IMO.
    For your common family email, you know you could just create yet another User Account and name it "Family Account" or whatever, and it would be the one which hosts family mail?

  • Open An Encrypted, Password Protected Saprsebundle Disk Image With iPhone?

    Is it possible to open an encrypted, password protected sparsebundle disk image using an iPhone/iPad/iPod Touch that is stored on a NAS drive connected to an AirPort Extreme Base Station?
    If so, how do I do it?
    If not, would you be able to explain why not?
    Thanks, Alex

    Hi Robert,
    > Once you through a sudo in there, you lose the option
    to have a regular user
       That's not really true. Sudo is one of the most flexible commands around and not only can a regular user use it but they can use it without a password. Mind you I'm not suggesting that you make all users admins; you can specify both of these privileges for this command only. All you have to do is to put a line like the following in your /etc/sudoers file. (with sudo visudo of course)
    ALL ALL = NOPASSWD: /usr/bin/hdiutil create -encryption -certificate*-stdinpass -type SPARSE -fs "HFS+" -volname-size
    I've included wildcards so that the cert file, volume name, size and image are arbitrary but the others must be in the user's command to qualify. I realize that you'll want different options to use FileVault certs but I don't know how to do that so I used your original example as my example.
       Of course it wouldn't be that easy for your lusers to get all of those options correct so the next thing you do is to wrap the command, with it's sudo preface, in a shell script that parses the cert file, volume name, size and image from the options the user passes to the script and puts those into the command with the right syntax. If you want to get really fancy, the script could prompt the user for any arguments that were omitted. Your lusers will think that you created this really cool command and never know that sudo was involved.

  • How to password protect numbers file on iphone?

    How to password protect numbers file on iphone?
    I've made a password protected numbers file on iMac and saved it to itunes.
    When i open this file on my iphone for the first time i have to type in the password. But afterwards it's not protected anymore and i can open the file without the password!
    How can i secure my files?

    There is at this time no way to put a password in the Numbers app nor on a Numbers spreadsheet, and as Michael said it's not something a third-party developer could add. You can suggest that Apple add a password feature via their feedback pages:
    http://www.apple.com/feedback
    or you can look for a third-party spreadsheet app that does allow password-protecting a sheet. Documents To Go from Dataviz is a commonly-recommended app that supports spreadsheets, but I don't know if they support passwording.

  • Password-protected Sparse Disk Image Bundle remembered after eject

    I use password-protected Sparse Disk Image Bundles to protect some files. Every now and then, when I open the image, it doesn't ask me for the password and opens immediately.
    At first, I thought I may have inadvertantly agreed to save the password in Keychains. But that is not the case. After running some tests, I noticed it may take up to 3 ejects before it asks me for the password again. It seems to happen more when I modify files in the disk image, but not when I simply read files. I suspect it is not completely unmounting the image.
    This is potentially a security issue. Any suggestion on what I can do short of re-ejecting images until it asks for a password again?

    You may have successfully increased the sparsebundle's potential capacity while failing to resize the contained partition. That seems to be what happened when I tried this myself. A resized sparsebundle containing the same files would not occupy much more space on disk than it did before.
    *Provided you have a backup*, you could try the following:
    Remount the image, then run Disk Utility and select the .sparsebundle (non-indented icon) in the left pane. Click on the Partition tab, and then see if you can pull down the lower right corner of the disk image partition to increase its size. If you can, then drag it to the bottom and click Apply.
    Again don't try this without a backup. It may not be worth doing in any event - it's easy enough just to make a new, bigger sparsebundle and copy your stuff over.

    I'm not sure what you are looking for, Joe. The passcode lock code is also required when restarting the phone after turning it off, and when rebooting after a reset procedure.
