Shredder methods

Ocky · Aug 28, 2007

Ayone know which method of shredding is used by AVG AntiSpyware ?
(eg. Guttmann, US DoD 5220-22 M or others).

I suppose shredding of folders (directories) can also be done ?

Regards.

Looking in my AVG AS (free) > Tools> Shredder offers the options 1 overwrite (fast) 4 (secure) or 10 (paranoid).
By comparison Ccleaner offers 1, 3, or 7.
Eraser 1,3,7, or Gnuttman35.
Guttman is 35 passes. DoD usually 7, I think. I would imagine 4 would be more than enough to take care of confidential data.
Sorry, I've rabbited on...

It really depends what your erasing, a single file; email or freespace. A single doesn't take long. I used to think A single pass of Pseudorandom Data was enough for wiping freespace till I tryed DOD 7 passes and came up with 1550 files just on C drive and I use Eraser v5.7, I rabbit on too. Sorry.

Thanks for rabbiting on. Seems Eraser is king, and I may give it a chance
on my 'puter. Carver, have you had any problems using the available
features Eraser offers ? The free-space wiping is undoubtably useful, but
there was a FAQ post complaining about the free-space being drastically
reduced after running Eraser.

Sorry somewhat off-topic maybe. Will allow moderators to remove.

Lost Space Issues
After running Eraser, the free space on my drive was lost or reduced noticeably. How can I fix this?
Option 1:
Untick cluster tips in Eraser preferences and select a one pass option and run Eraser again. This should return your full freespace allocation.

Option 2:
It could be that either Eraser was terminated abnormally or the system crashed causing the temporary files to be lodged there and the temp Folder (~ERAFSWD.TMP) may have used up your diskspace. You can remove the folder “~ERAFSWD.TMP” and all the files in it to reclaim the disk space
How to find the ~ERAFSWD.TMP Folder to erase it:
1. Open Windows Explorer.
2. Click on View->Options and Show Hidden Files.
Run a Find.
3. If found Erase it.
If you wish to use the command prompt you can type “deltree X:\~ERAFSWD.TMP”, where X is the drive letter

Option 3:
1. Run ScanDisk.
2. Using File Finder in Windows, look for files that were changed around the date/time you ran Eraser. This may find ~ERAFSWD.TMP.
3. Erase it.

Option 4:
Turn off System Restore in System Control Panel applet
How to turn on/off System Restore in ME
1. Right click the My Computer icon on the Desktop and click on Properties.
2. Click on the Performance tab.
3. Click on the File System button.
4. Click on the Troubleshooting tab.
5. Put a check mark next to 'Disable System Restore'.
6. Click the 'OK' button.
7. You will be prompted to restart the computer. Click Yes.
8. Re-enable the Restore Utility, follow steps one to seven and on step five remove the check mark next to 'Disable System Restore'.
9. Reboot again.
