OS X :: Secure Deleting Files Within An Encrypted Disc Image?
Jun 28, 2008
I have a question about OSX 10.4.11 and secure deleting. My understanding is that even after secure delete has been used to erase a particular file, older fragments of that same file can remain on the hard drive. Assuming this also applies to secure deleting files from a mounted encrypted disc image (created using the disc utility), would I be correct in saying that even if file fragments remained, once the image is unmounted, those file fragments would be encrypted like everything else within the disc image. I guess what I'm really asking is whether, when one deletes a file from an encrypted disc image, that file data is moved outside of the encrypted data blocks into clean drive space. I don't see why this would be the case but was wondering whether anyone knew.
I appreciate one can always use the free space eraser within disc utility to "mop up" but I'm still interested about individual file deleting.
(Btw, this is my first post and as a courtesy, I did search the forums for this topic but didn't find anything. If I missed something in my search and this has already been answered, apologies!)
Early 2011 Mac book pro running 10.9.4. Deleting iPhoto files does not create additional space. iPhoto is about 160gb, iTunes which I use for viewing slideshows remotely is about 135gb.

So my current backup strategy uses two western digital external hard drives. The first I have permanently connected to my iMac using Time Machine. On the second I use CCC to backup to every week and keep it in the trunk of my car as an offsite backup.
Just had a couple of questions to make sure I'm prepared for the worse... - What temperatures can hard drives survive at? Is there a risk of it overheating in my car? - I've read about some issues with CCC's backups. I'm currently backing up to an encrypted disk image - is there any way to verify the backup? If I just cloned the drive instead so it was bootable is there any way to encrypt it? And is Super Duper more reliable?
I have a 10 GB encrypted disk image on my macbook (type OS Extended (journaled)). I've pretty much filled up the space so I want to resize. I go into disk utility with the disk unmounted and 'Resized' it to 20GB. Then I mount it and go into the Partition tab. I drag the corner all the way down to fill up the space and hit Apply. It goes through the motions without error but it does not actually extend the partition to the resize. On the right next it then says something to the effect that the disk is read only and cannot resize the partition. The write status is read/write until I click apple....then it switches to 'Unmounted, read-only'.

I think i Have secure deleting on, on my Mac OS X 10.5.7. It takes a good 10mins to delete like only 200 files (relatively small, like picture/music/document files). I don't remember how I turned this future on, but how can I turn it off? Its really annoying how long it takes to delete something!!
I've done all of this and it won't open. I double click on it, the default program to open it is diskimagemounter and nothing happens when I double click.(Mac OS X Lion 10.7.4)
I got some good advice about deleting dmg files so I thought I'd ask about the Previous Systems folder on the HD. I recently tried to delete too much and had to reboot from the disk. It put a folder named "Previous Systems" on the HD and its taking up 7.72 GB. I'm back up again and up to date. Everything seems to be working. I know I screwed up before so I'm asking here before I delete too much again.
I go into System Preferences->Dektop & Screen Saver. As the program "loads" availabe image sources and such I get a pop-up requesting a password to my secure disk image. Yes, I have a secure disk image in my home directory. Yes, the secure disk image is currently "locked" (Not mounted in finder).
I click cancel (a few times, probably 2 maybe 3 times) and things continue along fine. I select a photo source that I want for a screen save and exit peferences. I then go an start the screen saver (I'm using Hot-Corners). I get the message "Looking for pictures....." for , well...basically forever...
Sure enough I touch the mouse to leave my screen saver and there is the pop-up again. Asking for me to unlock my secure disk image.
I thought this might be related to Spotlight. I tried reading several threads and have gone as far as taking my entire hard-drive/volume and putting it into the "Privacy" tab under spotlight.
how I might get it so the "Desktop & Screen Saver" stop prompting me to unlock my secure disk image? (WITHOUT having to make sure the disk image is unlocked before I sleep my screen or open the screen saver utlity) As always, I am only speculating that this is Spotlight related so that could be a red-herring....
I'm in a situation where I have a file (specifically, a pages document) that I want to encrypt with a password, and in the best of cases, hide it from spotlight searches and such.Any ideas on how to achieve this? Please consider that I have to constantly open, view and edit the archive at times, so a disk image, zip or rar file won't work for me.
I thought FileVault, but I don't really want all of my files with password, and it gave me the "not enough space on disk error" when I tried to do it anyways.I'm assuming this service is available in the OS itself, but I haven't been able to find it just yet. Or can anyone tell me of a program that allows that option without having to leave Finder?
i'm having trouble decompressing this multi part (.zip and .z01-.z03) files becuase i eitehr get an issue with the file not beinga supported archive or something along those lines usually. ive tried about 6 different decompression applications without much luck. i have a password for the files but havent been prompted to use it.
I have a few programs on their original DVD discs that I want to put on another computer w/ a broken disc drive. In theory, can I create a disc image w/ the disc utility program, copy that file onto an external hard drive, and then put it on the other computer that way and have the program as workable "disc" (but it will really just be the image of the disc). On a side note, if I got a new disc drive on that computer, would I still be able to burn that file to a DVD disc in the future to create an exact replica?
So I had to have my macbook pro HDD replaced (applecare) and I made a disc image backup beforehand and put it on my external HDD.
I just picked it up from the apple store today, and called tech support for help with restoring it from the disc image. I was instructed to put the install disc in and boot holding the 'c' key, then go to disc utilities, to the restore tab, find the image as a source, and then drag the internal HDD volume to the destination field. It didnt work, so I was transferred to a senior advisor, who told me to do the same thing. The only time it would work is if I dragged the indented one that reads "Macintosh HD" instead of the one with the GB size and brand name. The senior advisor told me that it wouldnt work for him either (dragging the volume) and dragging the macintosh HD isnt how it's supposed to work, so he couldnt guarantee a proper result. It didnt work anyway. I dont remember the error message.
So he starts telling me that the best option might be to install the operating system from the discs, update to 10.5.8, and then just copy the "user" folder and then move everything where it is supposed to be. I wasnt particularly impressed and I'm not convinced that it has to be that difficult or time consuming.
I am using Itunes Match as my music collection is bigger than my Macs memory. I downloaded tunes from the Cloud so I could put them on my old style Ipod, but now I need to delete them from Mac so the drive is free. If I delete them how do I recover them from the Cloud to my libary?
All I am trying to do is transfer ISO disc image over to an external Usb Hard dive. Any time I attempt to drag the file over I receive an error that says " Sorry, the operation could not be completed because an unexpected error occurred. (Error code 0)
I recently downloaded Transmission, and whenever I open the program, the disc image mounts on the desktop. I can't eject it until I quit the program, and then it always pops back up when I reopen the program.
I just bought a brand new 2.4ghz imac. I went to transfer data. Hooked it up with the firewire. When I tried to restart while pressing "t" the g4 made the happiness sound and ran for a bit then clicked off. Kept trying, got "there are no discs with osx on your computer" and some other error messages. The g4 starts up fine and runs otherwise. When I tried to do it with the migration assistant it told me that I have to be running the latest os on the g4. Well, according to mac, I can't f'ing run the latest os on the g4 because the machine only runs at 800 mhz.
I have a group of docs on my MBP that contain private stuff - bank a/c details etc...
Now I keep those files in an encrypted sparse disk image and I'm reasonably confident that if my MBP is stolen they won't be able to access that disk image.
But this just occurred to me: when I open those files in Pages is there a temp copy of the file save somewhere outside of the sparse disk image that could be found?
I really don't want to use file vault to encrypt the whole disk but I do want to be sure those private files won't get accessed.
I installed Windows 7 32-bit Home edition on a 200gb partition using Bootcamp. I am installing and tweaking the Windows installation and would like to take a snapshot of the system after I have installed all programs and settings.
I used Acronis True Image 2011 on my previous Dell laptop to take a disc image of my installation then used that on subsequent reinstallations using an Acronis boot disc and disc image accessed from a USB hard drive.
How can I reinstall the disc image of an Aronis True Image partition on a Macbook Pro 13" 2010 if part of the drive has OSX? Could I boot from an Acronis boot CD then reinstall the Windows partition on the MBP?
I am doing a project at Unnamed Wireless company, and I need to send out a updated Leopard image to 14 MacBook Pro's. this is a Apple that is used as a display device to show web surfing over EVDO. I need to know what is safe to delete or remove on the OS so I can possibly fit it to DVD dual layer media. Unless you can split Mac image copies to multiple discs with the built in image software.
my mid-'09 whitebook has a dvd in it that will not eject. there's no disc image on the desktop and i can't eject from the dvd player either... i've tried shutting down and booting up, and restarting....
this is my first issue with this computer so i'm pretty worried... is there any way i can force it to eject? i mean, without damaging anything...
I've been using an external HD as my disc image for Time Machine. Recently, both of my USB ports failed due to a juggling accident with cables connected to the ports. I'd like to send my computer for repair, but'd feel safer if I could backup before that.
Through file sharing and an ethernet cable I'm connecting to my old mac and can see the my HD for Time Machine, but how do I configure Time Machine to use that disc?

I'm not talking about a tool like Onyx, which is "excellent". Definitely the best, most simplest maintenance tool/utility.app for the Mac.I'm talking a simple tool for searching, editing and deleting both specific .plist files and cache files on an app-by-app basis. Is there one?I know of PrefEdit, but that is only for .plist (preference) files, and leaves out cache files:
I need, well desperately want; one that does both.Yeah I could use AppZapper, but I would prefer something that is designed for this specific purpose. Anyone?
I want to delete backup files that are more than a year old from my time machine. I moved them to trash and although it then asks if I want to remove secure items and I check yes, it then stops. As a result I can't securely delete any new files either since each time the same thing happens if I add a new file, none of it deletes.
I have a password protected disk image that mounts, but when I mount it there's a lock that shows up in the icon and I can't access the contents- "The folder "Disk Image" could not be opened because you do not have sufficient access privileges." When I Get Info it has my account, (unknown) and "everyone" all set with custom access. Ignoring ownership does nothing, and I can't change the permissions. I can't get at it via Terminal, and sudo chmod doesn't work either. How can I get at the contents of this disk image?
I made a backup image file of D2 LOD and im trying to install it again but the installer keeps telling me that i need to insert disc. So my question is, how do i mount this image so that the installer can use it.
Clarification: I lost the original cd so i just have this backed up image, so the image is legit.I just wanted to play this game and i dont wanna have to go buy the disk again.
i just deleted some files+emptied the trash... and just now read up about "secure empty trash", is there anyway to make sure the files i have already deleted are unrecoverable?
nstall Windows XP SP3 on my macbook with a dual boot. I downloaded it from Windows, and have an iso file. I used the disc utility to burn it to a disc, but when I try to use it with Boot Camp, Boot camp does not recognize it as a bootable disc.
In dreaded Microsoft word I use "Save As", then click "Options" and there is the option to save my file with a password so that my kids can't get in and muck up my business writing.
I can't see "Options" under "Save as" but I'm just trialling iWorks (full iWorks disc arrives next week).
