Filevault secure delete problem

Hi,
I installed Snow Leopard and updated my system and everything was running smoothly. It freed up over 17gigs on my hd!
Then I turned on Filevault with the option to secure delete the old home folder. While it was deleting the old home folder, ( after encryption) the progress bar got stuck at about 70% for about 2 hours.
I clicked "continue" so that it would delete the rest in the background while I used my mac.
Under security prefs it still said it was 73% after a long time so I thought something was wrong. I rebooted and it was about 76%.
I thought something was wrong so I disabled filevault and saw that there was about 15gb of space being used on my hd, ( presumably from the old unencrypted folder was wasn't deleted.)
Then I turned on filevault again in the hopes that it would work this time but it didn't. After it encrypted, it started to delete the home folder but after a while it said that "couldn't delete home folder" because a previous version of the home folder couldn't be deleted. But now there's another 15 gb of space being used on my hd, for a total almost 37 gb of space being used from the 2 instances where filevault was unable to delete the old home folders.
I guess I should've just let the filevault do its' thing the first time, but I really thought something was wrong.
My question is how can I get rid of the all that space that is being used ( the 37 gb). Can I use 'erase' from the disk utility, or will it not work? Should I do a complete reinstall of my computer???
I hope someone can help. Thanks

Hi, Dave.
re: A keyboard shortcut for Finder > Secure Empty Trash.
Such a keyboard shortcut is not defined by default. However, you can define your own keyboard shortcut for Secure Empty Trash within the application Finder using the instructions in "Mac OS X 10.4 Help: Creating keyboard shortcuts for applications."
If you think Apple should add one by default, I suggest you submit a Mac OS X Feedback.
Good luck!

Should files be securely deleted if using File Vault?

Do I need to "shred" or in someway securely delete files and mail that sit in File Vault? I am new to the MacOS and I am not sure where deleted files/mail go. If they don't leave the Home Folder it should be ok but if they somehow are relocated outside the Home Folder, I assume I would have a problem unless they are securely deleted.

Interesting question, sgmiller.
The default Trash location is a hidden directory in your Home folder, ~/.Trash, which would be in your File Vault, assuming the File Vault includes your entire Home directory and doesn't leave anything out.
When you delete a file, its directory entry is updated, rewriting the parent directory of the file to the ~/.Trash folder. Then when you empty the Trash, the directory entry of the file is simply removed and the file disappears from the file system. They don't really go anywhere, they just disappear. However, the bytes still remain on the disk until something else comes along and writes to those sectors, so Secure Delete can be used to overwrite the previously used areas of the disk with zeros.
I guess it depends on how careful you want to be. You may also be interested in using Secure Virtual Memory if you aren't already, under "System Preferences->Security".
Clear as mud, my apologies!

Mac Classic, System 7,0 (or 6.0.7), secure delete ...

A friend is retiring her venerable Mac Classic running System 6.0.7 (and MacWrite II) in favour of a grape iMac she's getting free from another friend (oh my, what a shock she'll have - from System 6 to OS 9 in one fell swoop!). Anyway ...
Moving the data over isn't a huge problem, I think she's opted for 1.44MB floppies and an external floppy drive for the iMac. It's the data left on the Classic that's worrying her.
I'm sending her my complete set of System 7 Install discs from my original Classic, which includes the Disk Tools disk, on which is the System Folder and HD SC Setup (version B1-7.0)
So, the question is (aah, finally, you're thinking!) ... Does the version of HD SC Setup as supplied on the System 7 discs for the Classic (they install System 7.0, although there is a "System 7 Tune-Up" disk too) and especially the Disk Tools disk have a secure delete option? Unfortunately the Classic in question is over 250 miles away so I can't get to it at the moment.
Will I need an third party utility to completely erase the data on the internal hard disk or will HD SC Setup do it?

Burn.sit is only 89 k-should work.
You can use a 7.5 DisTools Disk on the Classic. For DiskTools you may look at

Disable default "Secure delete"

Hi,
I encrypted my home directory with filevault and enabled "use secure deletion". Is there a way to reverse this setting? I can't find it in my System Preferences.
Kind regards,
Chris

Any add ons / third party apps?
It's a feature of MacKeeper.

Secure Delete gives me a "don't have permission to access some of the items

I am cleaning up my drives on a MBP and it came time to delete files from my trash.
Lots went but I ended up with several that blocks the delete process and I get a message "don’t have permission to access some of the items."
Well I did repair my permissions and tried the secure delete again and got the same message.
I do not have the option of doing just a plain delete.
Does anyone have a fix for me?
Thanks
Dunc

do not have the option of doing just a plain delete.
Of course you do (disable secure delete in finder prefs/advanced) - and when you do, a dialog will appear that allows you to enter an admin password. Delete all that fall into this category first...
Secure deletes take forever....why do that - if you're getting rid of the computer/hd, just format and zero it out then, instead.

Two Related (?) file deleting problems in Finder and Time Machnine

My internal drive is partition into two volumes. In the second one (the "non-boot" one), I was have trouble putting files in the trash that were locked. As I was tracking that down I coincidentally(?) started having another problem.
I started getting a message that the files being put into the trash must be deleted immediately. I check permissions and I had read/write Privileges in the user account I'm normally logged into. However, If I logged into my administrator account, I could put things in the trash without deleting them. I noticed that ignore ownerships wasn't checked, so I checked that.
That allowed my to put files into the trash without immediately deleting them. I went ahead and deleted the files I wanted to get rid of. However, I'm wondering if there was another issue because I am lead to understand that the ownership privileges shouldn't have necessitated checking "ignore ownerships"?
Also, I had trouble deleting the backups of those files and folders in time machine. I can delete most of it. But for one folder (and all the folders in which it resides in the hierarchy) I can't deleted it. I tell it to delete backups of that folder (or folders it is in), I put in the password, and goes "ding". But nothing disappears...
(After I wrote this, I tried unchecking "ignore ownerships" and the problem did not reappear. I can still put files in the trash without the immediate deletion problem.)

Are you doing that via the Finder or Terminal? If so, that's not the way to delete backups. See #12 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 the +Time Machine+ forum).
And now I'm getting an error in time machine. "Files can't be copied onto the backup disk because it appears to be "read only"". I do get info on the disk, and my account has Read & Write privleges, but it say "You can only read" above that".
The Finder or Terminal deletions may have corrupted your backups. Repair them, per #A5 in [Time Machine - Troubleshooting|http://web.me.com/pondini/Time_Machine/Troubleshooting.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).

I'm doing the deletion through Time Machine (I go into Time Machine, find the folder in the backup, and ask Time machine to delete all backups of that folder).
I did find the tip of unmounting the disk, rebooting, and remounting it. That Stopped messages about the disk being read only. However, the folder still doesn't delete. I'm also a bit worried about these being symptoms of some other problem...

Web Center app with ADF Security - login problem

I have a custome Oracle Web Center app.
I have a page.html with an embedded login form posting to j_security_check. I've configured the ADF security policies to redirect to a JSPX on successful login.
When I try the correct username/password, I get redirected not to the page I defined in ADF, but to the root page http://127.0.0.1:7101/MyApp-ViewController-context-root/
and i get
Error 403--Forbidden
I've checked the weblogic.xml as per http://andrejusb.blogspot.com/2009/12/solving-error-403-forbidden-in-adf.html, all the required entries are there.
This works fine if i use a Login link with
destination="#{'/adfAuthentication?login=true&end_url=/faces/postLogin.jspx'} "
which redirects to the default login.html and then to the right page. I've copied the form from the default login.html into my master HTML page.
Hope my question is clear. Any suggestions why it is going to the wrong URL after login.
Is there anything specific I should see in the jazn-data.xml or web.xml regarding the post-login URL since i cant see that in either.
P.S. Have been advised to try here when I originally asked this in the WebCenter forum. Web Center app ADF Security - login problem
Edited by: new_to_webcenter on 18-Jan-2011 05:25

Thanks for your response Frank.
The web.xml has
<security-constraint>
<web-resource-collection>
<web-resource-name>adfAuthentication</web-resource-name>
<url-pattern>/adfAuthentication</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>valid-users</role-name>
</auth-constraint>
</security-constraint>
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.html</form-login-page>
<form-error-page>/error.html</form-error-page>
</form-login-config>
</login-config>
When configuring ADF Security via JDev , I chose "Redirect upon successful authentication" to the Welcome Page
"/faces/postLogin.jspx"
this then adds into web.xml
<servlet>
<servlet-name>adfAuthentication</servlet-name>
<servlet-class>oracle.adf.share.security.authentication.AuthenticationServlet</servlet-class>
<init-param>
<param-name>success_url</param-name>
<param-value>/faces/postLogin.jspx</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
So the sequence which works is:
Login via the '/adfAuthentication?login=true&end_url=/faces/postLogin.jspx' and this redirects to login.html (OOTB form which posts to j_security_check) and then to the postLogin.jspx
I'm trying to do away with a Login link, and trying the simple login form embedded in my page alongwith other content.
So should the form be posting to j_security_check directly or to the adfAuthentication ?

There is a problem with this connection's security certificate The remote computer cannot be authenticated due to problems with its security certificate. Security certificate problems might indicate an attempt to fool you or intercept any data you send

Hi,
I have this Windows 2008 R2 on which I installed remoteapp some years ago.
Now the certificate expired and I get the message
"There is a problem with this connection's security certificate
The remote computer cannot be authenticated due to problems with its security certificate.
Security certificate problems might indicate an attempt to fool you or intercept any data you send to the remote computer."
How should I renew the certificate? I already went to certification store and tried to renew certificate with same key but then it says "the request contains nor certificate template information".
Please advise.

Does the computer account have Enroll permission to the certificate template?
From the Server running your CA, run mmc, click File then Add/Remove Snap-in...
Add Certificate Templates and click OK.
Find the certificate template, then right click and select properties. On my CA its call ed RemoteDesktopComputers but might be called something different depending on what what template your certificate is based on.
On the security tab, click Oblect types, check Computers then OK. Enter the Computername and click OK. Then give your computer account Enroll permisssion.

A 'cleaner' app with SECURE delete option?

Hi all,
basically, I work for the entertainment industry and my systems are sometime loaded with very 'for your eyes only' materials, such as scripts and videos for movies still on working, etc.
As the leaking of those material may cause me serious trouble, I'm especially concerned with the 'secure deleting' of sensible files, particularly to avoid any risk in case of any of my computer being stole.
So as for cleaning/mantainance I normally use our beloved OnyX, or CacheOutX (for simple tasks) yet both lack the option of 'secure deleting' (shredding, overwriting, call it as you like) what they clean.
I went and searched for any app capable of performing such a 'secure clean' of OSX, but failed.
This is too be for me, especially for OSX itself allow to use secure VM and has Secure Trash ans Disc Free Space ereasing built right in! So basically what I'm forced to do is 'Erease Free Space' out of my HDs EACH TIME I perform a system cleaning. This is, in a word, boring. Or seriously annoying if you like.
So, any clue to help me out?

SInce there are thousands of system files scattered all over the place, and various utilities may not keep track (unless you can extract them from a log file somewhere), securely erasing the free space after using something like Onyx seems like the thing to do. There may be existing maintenance scripts out there - perhaps a script run from one of the periodic utilities that uses diskutil.

How do I "delete" files that I emptied from the trash but not securely deleted

just dont want to waste memory

They are gone. Securely deleting a file or files in no way affects memory. It doesn't affect disk storage space either. I merely makes it more difficult for someone to recover data from a hard drive.

Secure Delete Apps

Hey what happened to the secure delete apps like iErase and iShred that you used to be able to get to ensure your deleted files were really deleted? Apparently they are not available in the US store?

When I downloaded photos from a camera SD card using an adapter, I noticed two Albums were created in the Photo app.(Last Import & All Import). Like you stated, there is no option to delete excess photos without deleting all of them. So this is the lengthy steps I went through to delet the extra album (I hope someone comes up with a shorter process):
1) Connect iPad into your PC (Make sure you configured to Sync with iTunes)
2) Go to My Computer > right click and open Apple iPad > right click and open Internal Storage > right click and open DCIM. (This will show the photos from those to Albums only)
3) Right click on a empty space on the desktop
4) Click on New > Folder
5) Go back to the DCIM files and right click on each file(one at a time) then copy and paste each file over the New Folder.
6) Go back to the DCIM files and open each folder and right click and delete each photo.
You will notice that all the same photos are being deleted on the Photo app simultaneously.
7) Then drag the New Folder into you Pictures on the PC.
8)Then open iTunes on your PC and click on the Photo tab and click Sync on the bottom right to import those photos back to your iPad.
I hope my scenario can apply to you.
