My Secure Empty Trash not working?

I click on Trash & open it, then I click on secure empty trash and open that, next an option to empty locked items appears, and I click that.
It appears to start deleting unwanted files for a brief moment, then stops and the files remain in the trash, taking up much needed space.
Could anybody please help me so I can dump this trash and get started collecting the next load?
Thanks

HI,
Goto Finder > Help > type in Trash...
From Finder Help Trash...
" Empty the Trash
Command (⌘)-Shift-Delete
Empty the Trash without any warning or when it contains locked files
Command (⌘)-Shift-Option-Delete
Hold down the Option key, and then choose Finder > Empty Trash "
Hope this helps...

HT1526 Secure Empty Trash not working

when I press secure empty trash : the items load up then when I press either of the options (locked or unlocked) it stays on screen for a few seconds then disappears ??

Hello. Thank you for your help. When I follow your directions using the
terminal window I get the following message: unable to execute /bin/rm:
Argument list too long. I have over 100K items in my trash folder. Could
this be the problem?

Secure Empty Trash not 100% safe

Recently I use finder to enter directly into Firefox's cache files and move all the files into the Trash. Next I use Secure Empty Trash.
After that, I used Data Rescue II to see what i can find.
I am very surprised to find most of the images that i have securely deleted.
I know the best way is to use Disk Utility's erase free space function, but if Secure Empty Trash is going to write the data 35 times over, and still can't get the job done.
Then using Erase free space's 35 times write-over isn't completely safe too?

Normally when a file is deleted insecurely, the data isn't deleted at all - the only thing that is removed is the reference to the data in the file catalogue. Overwriting a file even once (let alone 35 times) should prevent recovery by programmes like the one you mentioned that are designed to detect unlinked files and create new catalogue entries for them. Given the above, a few possibilities come to mind that could account for your observations.
One is that the files you recovered were not the ones you thought you deleted. For example, working with "TextEdit.app", any time a previously saved document is modified, an invisible "autosave" copy is created on the hard drive, intended to preserve any modifications in case the programme or computer crashes. This copy is removed insecurely once the changes are manually saved. If the original is then securely erased, it will be unrecoverable. However, data recovery programmes can easily recover the remnants of the multiple intermediate "autosave" files. I have no idea how "FireFox" works with cache files, but perhaps what you recovered was remnants from previous times you visited the sites that were cached in the files you securely deleted.
A second, less likely possibility is that your files were recoverable due to a design flaw introduced in Leopard's version of "Secure Empty Trash" (I haven't tested recently so I don't know if the issue has since been addressed). It is possible to configure it so that files are not securely deleted, even when selecting the option. However, such a configuration would not be a random occurrence - basically, a user would have to set it themselves, although malware or a malicious person with access to your account could do the same...
A third possibility, perhaps related to the second, is that in Leopard, regardless of whether the over-writing stage of "secure empty trash" succeeds or fails for any reason, the process will still continue to the unlinking stage, in effect deleting insecurely. Prior to Leopard, if over-writing failed, the file would not be unlinked, which had at least two benefits: i) since the file was never insecurely deleted, it would not be necessary to initiate a time consuming "erase free space" procedure to ensure that the data was destroyed; and ii) the very presence of the file serves as feedback to the user that the procedure has failed, unlike in Leopard where it fails silently.
Either way, using "erase free space" shouldn't be affected by these issues. If the file has been deleted (i.e. copies do not still exist in a hidden cache file somewhere), then overwriting "free space" should prevent basic recovery software from restoring it, assuming the procedure is allowed to run to completion.

Empty trash not working in safe mode

eemptied cache into trash. Booted in safe mode. Now empty trash in safe mode not clearing the cache trash. Help needed. Thx.

Why would you even want to empty the Trash in Safe Mode? You should do that in normal mode, I suspect yo don't quite understand what Safe Mode is for, please read Apple's OS X: What is Safe Boot, Safe Mode?

"Secure Empty Trash" Didn't Clear Space on HD

How can I reallly clear the space formerly occupied by BackUp files?
When I used "Secure Empty Trash" after putting lots of BackUp files in the Trash, there was no change in the amount of available HD space. I have about 10GB of applications and files on a 60GB HD, so there should be about 45 GB of free space, but there's only 4 GB available.
FWIW, I've Repaired Permissions (only a few were necessary) and Restarted to no avail. I've used "Secure Empty Trash" to remove another file, and it worked just fine!
So how can I clear the part of my HD that I asssume is written with random 0s and 1s left by "Secure Empty Trash", not real files?

John:
Thanks for hanging in there with me! As you knew it would, WhatSize worked.
It identified the old Backup files (that the Finder didn't) and transferred them to the Trash. I used Secure Empty Trash delete them. This time it worked correctly and I have space for Backups again, thank-you very much!
If you have any idea why it didn't work the first time, I'd appreciate knowing it. I've never used it before, so I don't know if it has a repuitation for being buggy or otherwise problematic.
The name "WhatSize" was a little misleading.... I initially thought it would just do what the Finder's View > Show View Options > Calculate all sizes command does. Some of the comments on the Version Tracker site supported that idea, so as the stubborn Dutchman that I am was reluctant to do something that might make matters worse.
I also never considered the possibility that using Secure Empty Trash (as I had) would convert files into hidden files..... especially since I've never had such an experience in uising standard Empty Trash in 25+ years of Apple II and Mac use.
As you expected, I have learned that lots of HD space is devoted to hidden files (that once were visible in the "old days", if I'm not mistaken).
In any case, I very much appreciate your wisdom and willingness to keep replying when I didn't take your suggestion! Thanks!
Cheers!!

Secure Empty Trash Setting not working HELP!!!

Im trying to turn off the secure empty trash I dont know how it got turned on
but its not working
Ive tried going to Finder > Preference > advanced > uncheck the secure empty box
but it doesnt work it keeps asking me if im sure to delete the item
I dont want secure empty trash i like keeping the files for a while just in case
HELP please

Click on the item in the Finder's sidebar with the house icon and verify that you are able to write to this folder in the Ownership & Permissions section of the Get Info window, and that it isn't locked; if it is already set this way and you get that error, open the Terminal in the /Applications/Utilities/ folder and run the following:
mkdir ~/.Trash
If you get a message stating that the folder exists, run the following:
sudo chown $UID ~/.Trash
chmod u+rwx ~/.Trash
The first command in the second set will prompt you for your administrator password; nothing will appear in the Terminal window while it is being typed. In either case, click on the Finder icon in the Dock with the Control and Option keys pressed, and relaunch it.

After i empty trash (the secure empty doesn't work either), the system does not reclaim the free space.

After i empty trash (the secure empty doesn't work either), the system does not reclaim the free space.
I need to run the erase free space option from the disk utility every time...which is really annoying and time consuming.
Any ideas how to solve this?
Thanks in advance =)

There is a thing in iPhoto whereby the first time you delete a photo it asks if you want to delete or just remove from the album, something like that. Unfortunately it is one of these things with a "don't ask me again" checkbox. Now, "deleting" photos only removes them from the album they are in. To actually trash them I must then go to "all photos" and find them, to send them to the trash. To help find them, what I do is rename them zzz or something, so sorting them will get them to the bottom of my collection. Just maybe your photos are still lurking around?

Secure Empty Trash doesn't work

Working in Mavericks on an iMac 27. Secure Empty Trash starts but disappears and nothing is deleted. Is it safe to use Erase Free Space in Disk Utility?

So it won't help me at all. I don't quite see any use for it, a good reason not to use it. But I have some 560 000 files in Trash and they won't budge.
When you delete a file (without Secure Empty Trash), all the data of the file still exists on the file system free list. It will remain there until the file system reuses the space. Erase Free Space is a way to address this, after files have been deleted.
It is only really useful as a once in a while event, such as someone forgot to use Secure Empty Trash for a file with sensitive data. And Secure Empty Trash is very time consuming, and worse it is if you have an SSD, this wears out the SSD faster.
A better approach is to use FileVault so that a deleted file is instantly securely deleted because it was always encrypted.
Since you are attempting to use Secure Empty Trash, then I would try this from the command line using the 'srm' command. "man srm"
srm -f -r -v ~/.Trash/*
The srm command will perform a secure erase. The -f will keep it from prompting for approval. The -r will recurse through and directories of files in the trash. The -v will display the progress while deleting so you can see how things are going, and have an idea of how much progress you are making.
Be very careful with srm, as if you point it at the wrong directory it could delete something you care about, or a lot of somethings.
If there are files that srm -f will not delete, then you bring out the sudo command. But be VERY CAREFUL with sudo, as you can delete a lot more than just a few files you care about.
sudo srm -f -r -v ~/.Trash/*
Password: you enter your account's password here, assuming you are the admin of the Mac.

My secure empty trash keeps stopping and saying 'I do not have permission to trash" I ahve checked the file info and there is no tick in the locked box also the files are from a memroy stick

My secure empty trash stops and will not let me empty the trash. It says; I do not have access to some of the items. I have clicked continue, but it will not empty them. I have tried looking at the files in the trash box and the file info does not have the "locked box" ticked. Any suggestions please.

Open Terminal.app(/Applications/Utilities/Terminal) and type
sudo rm -rf ~/.Trash
Be careful all of files in the trash are deleted with above command.

How do I make trash not do a "Secure Empty Trash"?

Here is what's happening to my Trash whenever I move a file to it for deletion. Ever since I changed the Trash settings to "Secure Empty Trash", and I securely empty the trash when it only have 1 or 2 files in it, it comes up saying there's like 20. when there isn't...so help?
OR Could someone tell me how to chnage the Trash settings so it is just "Empty Trash".
Thankayou.

Uncheck "empty Trash securely" in Finder > Preferences > Advanced tab.

Is it possible to create a secure empty trash shortcut in file menu?

I have second finger click enabled so that I can quickly move files to the trash bin from the contextual menu. This is fine and dandy, however, for files containing sensitive informaton, I'd like to have a "Secure File Delete" option available (file bypasses the trash bin and is wiped after selecting said option).
I've searched the threads and checked system prefs. Only options are to change "empty trash" to "secure empty trash". This wouldn't work as I have more files that are typically trashed and not wiped. It'd be nice to have it available as a convenience I suppose
I know theres an app in the app store that offers this functionality. It's $3-4.
So my question...is it possible to create such a contextual menu option on my own?
heres an example of what I'm ltalking about...

Create a new Service in Automator.
Set it to receive files an folders in the Finder.
Drag in an Ask for Confirmation action if you want it.
Drag in a Run Shell Script action from the Utilities section of the Library.
Set it to Pass Input as Arguments and Replace the code with:
srm -r "$@"
--That's ess-ar-em for Secure ReMove (just copy and paste)
Save it and it will show up in the Services menu when you right-click on an item in the Finder.
There are options you can add to it like -s for simple, -m for medium. The default (without options) is 35-pass Gutman.
You can see what options are available by opening Terminal and typeing
man srm
Hit space to scroll down. Q to quit the man page.
The Verbose and Interactive options won't work since you can respond.
Note that depending on the algorithm chosen, it may take some time for the file/folder to disappear from the Finder view.

What exactly does "Secure Empty Trash" do?

There's very little technical detail on the web about this. I'd like to understand exactly what secure empty trash does.
What method does it use to overwrite?
How does it deal with temp files?
Why does it take so long?
Why, when there's only one file in the trash, does it always claim it's erasing 9 files?
What other files is it erasing in addition to the visible trash contents?
Can it work across network connections and external drives?
Has the method changed in Leopard?
etc.. etc..
Feel free to get all technical, if you know the answers!
Thanks!

What method does it use to overwrite?
It writes over the files with 0's.
How does it deal with temp files?
Not sure what you mean. It treats any file in the trash the same. Could you elaborate?
Why does it take so long?
Because it has to first write over the item with 0's, then delete the item.
Why, when there's only one file in the trash, does it always claim it's erasing 9 files?
What other files is it erasing in addition to the visible trash contents?
It's a bug.
Can it work across network connections and external drives?
Yes.
Has the method changed in Leopard?
Not that I know of.

Secure Empty Trash just gets stuck

Secure Empty Trash doesn't work. it just gets stuck/crashes. Why is this?
10.9.5 mavericks

from Apple docs worked for me. Mine was \\\\\\\.\\\ derived from installing Windows.
If there are several locked files in the Trash, you can unlock them all at the same time at the command line. Follow these steps:
1. Open Terminal. It's located in /Applications/Utilities.  Type: chflags -R nouchg  Note: Type one space (not pictured) after nouchg in the line above, so that it ends in "nouchg ". Do not press Return yet. 
2. Double-click the Trash icon in the Dock to reveal the contents of the Trash. If necessary, arrange the Finder window so that a portion of the Terminal window is still visible.
3. Press the Command-A key combination to select all files in the Trash.
4. Drag the files from the Trash to the Terminal window.  Note: This automatically enters the pathname for each file. This eliminates the need to individually empty multiple Trash directories, particularly when multiple disks or volumes are present. 
5. Press Return. No special text message will be shown indicating that the command was successful.
6. Empty the Trash.
If the Trash does not empty or if you see a message in Terminal that says "usage: chflags [-R [-H | -L | -P]] flags file..." you most likely did not type the text in step 2 as indicated or did not leave a space. Repeat the steps if this happens.

Does Secure Empty Trash Accomplish the same task as Running disk util to wipe free space

Does using the secure empty trash option accomplish the same task as running disk util to eliminate free space from old deleted files? I'm currently running the 7 pass deal on my late '12 iMac. Says its gonna take 7 hrs. Can I use safari or iTunes while the Big Mac works its magic?

Does using the secure empty trash option accomplish the same task as
running disk util to eliminate free space from old deleted files?
No.
Finder > Empty Trash just tells the file system that those areas on the drive are now available for overwriting with new data. Data deleted off hard drives can be recovered if this method is used before it's overwritten with new data with special software.
Finder > Secure Empty Trash runs a 7x pass military approved overwrite only on the deleted files in the Trash, works for hard drives only.
Disk Utility > Erase Free Space creates a huge file that takes the remaining free space on the volume selected and either writes zeros or 7x pass, then confirms it and then removes the file. Takes a long time to complete, do not interrupt.
This can be used if one forgets to use Secure Empty Trash or wants to scrub caches or other files that don't necessarily go to the Trash for user deletion, such as program files that self delete and download cache files etc.
Only works for hard drives and there is no recovery possible for nearly all users. Those with special expensive magnetic equipment can possibly recover data off a zero pass, but not off a 7x overwrite.
The zero erase free space can be also be used to pre-eliminate potential unknown bad sectors on hard drives before wanted data is written to them, thus preventing future issues with data retention on hard drives.
Disk Utility > Erase - (not moving the slider) will erase all data on the volume or partition selected, including wanted data. It just tells the file system the deleted data is ready for overwriting. Thus can be recovered using special software before it's overwritten on hard drives only.
Disk Utility > Erase w/Security Option - (or moving the slider from the left) will secure erase all data on the volume or partition selected, including wanted data.
It can vary on the operating system version used from zero pass, to 3x overwrite, to 7x overwrite to 35x overwrite (old version for days past of smaller drives, don't use on newer larger drives as it will take weeks to finish.)
Secure erase methods are used to secure erase private data off of hard drives only, doesn't work for SSDs.
For secure data deletion off a SSD or any flash media, it's NSA advised to grind it into a fine powder.
How do I securely delete data from the machine?

Secure empty trash very slow

Are there suggestions for speeding up Secure Empty Trash?

I got a tip from a Genius at the Green Hills (Nashville) Apple Support Bar today on how to instantly empty the Trash folder. This comes with a big warning/disclaimer: you will not be prompted about any of the action to delete the contents of your Trash as this sequence of steps force deletes all trash. In other words, there's no turning back. I did this after facing 8 hours of a trash emptying cycle to get rid of 280,000 files...
Here it is: while simultaneosly holding down Command + Option keys, press Shift and then press Delete (all four, in that order).
It works - it's instant! But be sure you want to take this action.
