How Safe is a Password Protected Disk Image?

I've created a Disk Image Volume with a password on my hard drive and have placed sensitive files into it as an alternative to using File Vault. Does anyone know if there is a way that these files be accessed without the password?
Thanks,
Joe

If you created the Disk Image Volume with a Password then it cannot be acsessd without said password.
It is the same with Filevault.. You cannot make changes without a Password.....Don

Trying to create a password protected disk image in 10.8.4

Trying to create a password protected disk image in 10.8.4. I follow steps in Apple:Support but I get an error saying "Resource busy"?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Version doesn't work on external password protected disk image

Version doesn't work on external password protected disk image.
Any ideas?

Hi
Did you assign the external monitor as a primary display in the graphic properties?
I think you did it due to the fact that the Toshiba boot display appears on the external monitor.
But just moment please. The Tecra M7 was delivered with the Win XP Pro tablet edition and not with Vista.
Did you install it at you own hand?
I presume everything has worked running Win XP
Maybe you should try remove the graphic driver from the Vista system and use one from the 3rd site like www.laptopvideo2go.com

USB Flash Drive (with password protected Disk Image) copies files very slowly. Why?

I'm backing up some data onto a 32GB flash drive that I've put a password-protected Disk Image onto, and am copying this data into, but it is achingly slow. It's taking hours to copy just 500MB!
I have another 64MB flash drive that I have set up the same way, but this one copies files very quickly. I can't spot any difference between them in Disk Utility/System profiler.
For the record, the process I've used for bothe drives is reformatted to Mac OS Extended (Journaled), then created a new Disk Image onto each drive (just a bitsmaller than the maximum size of the drive to enable it to fit) with 128--bit encryption.
Does anyone have any idea why the 32GB drive would perform any differently? I am using the same USB port on my iMac for each drive, but am getting very different copying speeds. It's driving me nuts! Many thanks.

The drive seems to be working fine if I copy files onto it outside of the Disk Image file (there's about 200MB of free space left over after I added the DMG). So I can only deduce from that that it is something specifically to do with the DMG itself. Though, as mentioned, I compared the DMG on my (fast) 64GB stick and the DMG on this problematic (slow) 32GB stick in Disk Utility/System Profiler (and I originally set them up in an identical way, as far as I am aware), and they seem to be the same. But one is performing achingly slow. Even dropping a file into the mounted DMG takes a few minutes to even think about it. It's very odd.

Cannot open leopard password protected disk image

i had created a password protected disk image under leopard. Now that i have snow leopard i can't open it anymore with the right password. Since then i know that i have changed the name of the disk image also. does anyone know if either changing the name of the image or upgrading from leopard to snow leopord would explain why i cannot open the image anymore?

Neither change should matter. I suspect that the password is wrong, maybe missing a cap or lowercase item or a number. Find someone running Leopard, copy it over, and see if it'll open there.

How big can a password protected sparse image be ?

I'd like to make a sparse image fit on a 3tB external USB 2.0 WD drive (I haven't bought it yet), can I make
one that's as big as 3tB ? (or close to it ?).
I'm backing up a drive with lots of information on it and it's going to stay at work as an
offsite backup..
Or is there a good way to PW protect such a big drive ?

With a single sparse image (not FV, which uses bands, but still quite risky) it's an all your eggs in one basket thing. Especially with a sparse image that large, if there's any file contamination, the whole thing goes bad and you lose it all. As Linc said, "as long as it's not your only backup." I woudn't trust it. Not only that, but the technology of a 3TB drive, itself, may not be that stable. You are looking at two layers of potential instability.

No password asked for Protected Disk Image...

I set up a Protected Disk Image using the given instructions yet when I click on it it does not ask for the password I set for it...? I thought it worked by having to ask for the password before it opens...?

It can be, that the password is saved in the keychain. When it is, it not ask for the password.
When you create an Protected DiskImage, you can choose if the Password should saved in the Keychain or not.

How Can I Password Protect An Image Field

Is there a trick that you know of to password protect an image field?
I have an image field, Only few directors allowed to use it.I want to restrict others from using it.

var pswd = app.response("This image is protected by a password. \n Please enter a valid password.");
if (pswd == "password"){ ImageField1.access
= "";} else
{ app.alert("You entered an invalid password!")

How do I open password protected email attachment?

Does anyone know how to open a password protected attachment in email.
My email will not download the attachment if it is password protected

I have the same problem. When a password protected attachement is sent to my iPhone, there is no icon attached, only the code in the email. However, it's normal when I view the email with my PC (Fire Fox or IE). The same thing happens on the iPhone 3, 4 and iPad 3. If a PDF file is not password protected, the PDF icon appears and all I have to do is click on it and it opens. Does anyone have any ideas? Apple Support is clueless on this one.

An easy way to password-protect certain folders
To password protect a specific folder in any version of OS X, if you're an administrator, simply change the permissions in the "Get Info" box so that the folder is owned by the system. You'll be prompted for a password. To access the folder again, just change the ownership back - and it will require a password to be made accessible.
Secret Folder lets you conceal a folder and its contents.
