In order to wipe Free Space, you need to have Administrator write access to the root directory (/).
If you are the only user on the computer, you should have that by default.
If there is an Administrator for the computer,
– Log in as the Administrator
– Run the Disk Utility and Repair Permissions on your startup disk
– Run ShredIt again.
If its still not working, then
– launch the terminal and type this command: sudo chmod ug+w /
– You will be prompted for the admin password.
– Then run ShredIt again.
If following these steps doesn’t solve the problem, contact support.
None of the files left in a ShredIt X Items folder are completely erased. You need to drag the ShredIt Items folder on to the ShredIt X icon to finish erasing.
If the files will not erase, there may be a problem with your hard disk. Please contact Support.
(Please Note: ShredIt X did not cause the problem with your hard drive. The inability to erase is often indicative of bad sectors on the drive, an early indicator of a failing hard drive.)
Yes, but you want to ensure that Time Machine is not backing up the ShredIt X temporary file when you are wiping free space. Configure Time Machine to “not” backup the ShredIt X Freespace folder. (You only need to do this once, not every time you shred freespace.)
Follow these instructions:
– Run ShredIt X and start wiping free space. (You have to create the temporary file so you can exclude it from Time Machine.)
– Open the System Preferences and Select “Time Machine”.
– Click the Options button.
– Add the ShredIt X Freespace folder to the Time Machine “Do not back up” list On the Time Machine “Do not back up” Dialog, and Click “+”
– Using the window, find the folder HardDrive>ShredIt X FreeSpace
– Select it using the “Exclude” button
About Shredding | Erasing | Secure Delete
Throwing a file in the trash does not remove the file contents from the hard drive – it just removes the file name from the directory, leaving the data intact and vulnerable. In order to securely delete the file contents from the hard disk, you need to overwrite the area on the disk where the file contents are stored with other data. This is what ShredIt does. In addition, you need to ensure that you securely delete all copies of the file. When you edit a file, the app will create and delete working copies each time you save, leaving multiple copies of your file on the hard disk in the disk free space area. In order to securely delete these copies, you need to shred your free space. ShredIt also does this. For more information, read “Secure Delete versus Delete – What’s the difference?“
If you are using a File Recovery App and you shred files using ShredIt or NetShred, you will be able to recover the names of the files you have shredded, but not the contents. For an explanation of why, read on.
A File Recovery App will recover files that have been erased. It does this by keeping a separate directory of the files on your hard drive and keeping the current location of the last contents of the file. So, if you accidentally deleted your doctoral thesis, you could recover the file using a File Recovery App. But, if you had made changes to your thesis first, saved it and then deleted it, your File Recovery App could recover the file, but not recover it the way it once was, before you changed it.
Both NetShred and ShredIt work by overwriting the contents of each file with other data before deleting the file. So, even if you use a File Recovery App, it can’t recover data in the file the way it once was before NetShred or ShredIt overwrote the file with other data. It can, however, recover the file name since it stores this in it’s own directory file.
Since the function of a secure delete app is to make files unrecoverable and the function of a file recovery app is to make files recoverable, you have to decide which is more important to you. We’d recommend the following:
– Since a File Recovery app stores the file name in it’s own directory file, using such an app will make it possible to recover the file name. If you don’t want this, don’t use a file recovery app on your computer.
– If you don’t want to be able to recover the contents of any file you have shredded, but do want to be able to recover the contents of any file you have deleted, use both a file recovery app and a secure delete app on your machine. (Just make sure you don’t shred a file you might want to recover.) This will be a good compromise provided that the ability to recover the file name does not compromise your security.
To assess your risk, take the ShredIt Quiz
By shredding | wiping | erasing, we mean that for each requested file ShredIt will overwrite the contents of the file. The pattern of bits which ShredIt will use to overwrite with is configured by the user. The default pattern used is proprietary. The number of times the data will be overwritten is configured by the user. The default number of times the data is overwritten is proprietary.
